The release of new p0.62 micro led and p0.62mini LED display solutions of crystal stage has a milestone significance for the whole LED display industry: p0.62 level spacing display can realize 110 inch 4K ultra high definition display, and achieve the same definition as traditional LCD display, Thanks to the advantages of high contrast, high brightness and wide color gamut, the LED industry has entered the trillion level display market from the professional display market.

Mini LED P0.62 level display used in the trillion level display market will accelerate the application of Internet display terminal, promote the rapid development of new retail, and bring about the rapid popularization of home market. यद्यपि, in order to break the industrial barriers and turn the cross-border concept into reality, the pioneers of LED industry still need a number of pioneer enterprises to drive the industrial chain to be relatively mature and controllable, which is what crystal stage plays Role.

Holding high the banner of 5-year quality assurance, the high-end KS series of crystal stage opens a new era of ultra-high-quality display devices

In addition to the release of new displays, one of the major actions of crystal stage this year is to advance into the high-end display highland. KS series once appeared in the Netherlands ISE 2020 प्रदर्शनी, it has attracted a lot of attention. It is regarded as a new benchmark in the industry of ultra-high-quality display devices. What kind of luxury gene does it contain? To this end, crystal RGB product manager Yang Yong officially released high-end KS series for the whole industry.

When it is manufactured with ingenuity, KS series adopts top-grade raw materials, unique structural design and surface treatment process, which can improve the performance of various aspects by more than 30% for the use scenarios. Its super energy-saving and long-life performance advantages completely solve the biggest pain point of fixed installation, and it still has ultra-high stability in high heat, cold and high humidity environment.Based on a lot of excellent product quality, crystal stage officially announced in the press conference that KS series all provide super long 5-year warranty, providing the highest service for customers.In addition to the release of new products, the trend of LED display industry in 2020 has become the most concerned hot spot. While China has leapt to become the world’s highest LED production capacity base, two high-end application trends of LED display industry are emerging cinema and conference hall

Let’s take a look at the trend of decreasing pixel spacing in LED displays. In 5g era, if the pixel spacing of 0.9375mm is adopted, the size of 8K screen is 325 inches and the height is 4 मिटर (the screen of 4K is 163 inches). If the hospital or epidemic prevention center has enough space, then the LED screen of p0.9 is a better choice; if the screen height of 8K is limited to 2.7m, then the pixel spacing needs to be 0.625mm.

When 5g solves the transmission problem, the display screen of the key hardware device must also keep up with it. For better experience, telemedicine display is developing towards large screen and high definition. हाल, the mainstream display equipment LCD screen, when the size is between 100 inches and 120 inches, is expensive, inconvenient to transport, and the larger size needs to be spliced. This is an extremely serious problem for the medical industry which pays great attention to rigor, accuracy and sensitivity. After years of technology accumulation and market expansion, LED display screen has not only completed the major transformation from outdoor to indoor, but also driven by the mature small spacing, 3D and touch technology, and the trend of continuous narrowing of spacing, it has a greater space of development in the field of medical display, and is expected to have high expectations.

त्यसैले, in recent years, LED display has the advantages of large size and seamless splicing because of its high resolution, कम चमक र उच्च खैरो, HDR, response speed and other indicators, which can show all the details of medical images and help doctors improve the accuracy of diagnosis.

In particular, as the distance between LED points continues to narrow, the realization of 8K ultra-high-definition display, combined with 5g ultra-high-speed transmission, will have a revolutionary impact on telemedicine.

Let’s take a look at the trend of decreasing pixel spacing in LED displays. In 5g era, if the pixel spacing of 0.9375mm is adopted, the size of 8K screen is 325 inches and the height is 4 मिटर (the screen of 4K is 163 inches). If the hospital or epidemic prevention center has enough space, then the LED screen of p0.9 is a better choice; if the screen height of 8K is limited to 2.7m, then the pixel spacing needs to be 0.625mm.

हाल, for high-definition display solutions below P1.0, as early as June 2018, National Star optoelectronics, the leader of RGB display packaging devices, simultaneously released the first mini LED device imd-m09t with integrated matrix devices integrated packaging technology in China and the United States, which effectively solved the problem of commercialization of p0.x in the industry and won the approval of the mainstream market.

For the p0.6 LED display, from the packaging point of view, the new mini LED display application imd-m05 appeared at the just concluded ISE exhibition in the Netherlands, which has made a good technical and market layout for products below p0.6 and micro LED applications.

To sum up, although LCD and other display technologies are still the mainstream of medical display, with the support of 5g and micro spacing LED display, it is expected to help telemedicine Ultra HD and accelerate the arrival of revolutionary experience. And the novel coronavirus infection is a major practical opportunity for China’s telemedicine industry. It is a great training, and will provide valuable research samples and experience for 5G and the super HD display energy medical industry in the future.

हाल, novel coronavirus is the first to launch a visualization solution for LED display enterprises. It hopes to provide the epidemic prevention and control command with the fastest speed to help improve the quality and efficiency of epidemic prevention and control. This is also one of the fastest remote prevention and control guidance programs.

We remind LED display enterprises that they may seize the opportunity to research and develop the integration of LED display in telemedicine.

LED display industry enterprises are faced with the audit problem of returning to work. Before that, due to the impact of the epidemic, local governments have postponed the work hours to after February 9. यद्यपि, the condition for returning to work is that the enterprise should provide the application for returning to work, which can only be resumed after the examination and approval. In the application process, the relevant departments review all enterprises one by one. This audit takes a certain period of time, and most of the enterprises in the LED display industry are small and medium-sized enterprises. It will be difficult for small and medium-sized enterprises to pass the resumption audit. Fortunately, on February 17, the Shenzhen municipal government began to cancel the approval of enterprises’ resumption of work verification and filing, and changed it into the enterprise filing commitment. As we all know, Shenzhen is the most perfect area of China’s LED display industry chain.

On the way back to work and production, we also see that some enterprises in Zhejiang and Fujian hire buses to pick up colleagues and return to their jobs when public transportation is inconvenient. Among them, 15 return to work buses in Dongyang, Zhejiang Province, travel all night to transport personnel from Guizhou Province to Zhejiang Province and return to work with police cars. Yiwu has opened a special train, shouting the slogan “you come to work, I’ll pay the bill.”. LED display industry is a labor-intensive enterprise, if there is a need, related enterprises can also use a similar way to receive workers to work. तेस्रो, there will be some difficulties in the life and work of LED display enterprises after returning to work. In the current epidemic situation is still tense, LED display enterprises need to provide sufficient protective equipment for employees. Such as masks, disinfectants, protective clothing, thermometers and so on, these resources are still in a relatively scarce state in the market, but with the continuous overtime work of some enterprises related to protective equipment, the market gap of relevant protective equipment will be further reduced. As one of the manufacturing industries, LED display enterprises have their own factories. It is inevitable for many people to gather in their daily meals. LED display enterprises will also manage their employees reasonably and effectively, such as separating people from each other when eating, so as to avoid personnel infection as far as possible. अन्तमा, LED display enterprises are faced with the problem of difficult to resume production.

With the further control of the epidemic situation and the further solution of various traffic problems, it is only a matter of time before the LED display enterprises return to work. After the problem of returning to work is solved, LED display enterprises are faced with an arduous task of resuming production. Affected by the epidemic, many LED display enterprises have been affected. On the order side, the orders of many enterprises will be reduced, but with the control of the epidemic situation, new orders will continue to be released. उदाहरणका लागि, the Tokyo Winter Olympic Games will be held in 2020, and the holding of the Winter Olympic Games will also release new orders for industrial enterprises. In terms of raw materials, LED display industry is an integrated industry, and the production of LED display needs the cooperation of upstream, midstream and downstream industry chains. In the face of a sudden epidemic, enterprises in the industry with raw material inventory can make timely emergency response, even enterprises without raw material inventory can coordinate effectively through the strength of industry associations.

Aviation media has an audience advantage over other outdoor media advertising. In aviation media, airport LED display screen has become the most advantageous media with its unique location resources and digital technology characteristics.

1. The audience belongs to high-end social groups

The overall characteristics of airport media audience tend to young and middle-aged married group with high education background. They have high income level, strong consumption power and significant business background, and take civil aviation as the main travel mode. 67.7% of the audience said that the quality of goods was one of the main factors affecting their consumption decisions, र 59.1% of the audience would be affected by brand awareness.

2. The airport led transparent screen enhances the value feeling beyond expectation

Compared with other types of media, led transparent screen itself as a high-end, fashion technology products, easy to form a high-end media image in the minds of the audience, and has a higher psychological expected price for advertising products. Like a car, if it appears in the airport led transparent screen, the audience thinks the price of the model is 300000 युआन. If it appears in the commercial street LED screen, outdoor brand or building LCD TV, the audience’s psychological expectation price is low, बारेमा 250000. त्यसैले, the airport led transparent screen advertising can effectively enhance the audience’s perception and expectation of the value of goods. त्यसैले, the airport led transparent screen has more advantages in improving the value and image of high-end durable goods and luxury brands.

3. Airport led transparent screen promotes brand value

If it is to shape and maintain the brand image, we can hold a long-term and stable advertising plan in the airport led transparent screen. For advertisers who want to quickly promote new products, they can consider putting a large number of airport led transparent screen advertisements in a short period of time. Advertisers should make full use of the more shocking visual effect of transparent LED display screen and attract more audience attention through better advertising creativity.

Outdoor LED advertising screen media is the development trend of the advertising industry in the 21st century. It is a kind of indoor and outdoor advertising display equipment with audio and video functions. It is a leading high-tech product in the world. This kind of equipment has a novel and unique appearance, and its area can be adjusted at will. It can not only play audio and video advertising programs, but also can install fixed light box advertising space on all sides. Now local governments encourage the use of outdoor LED screens, and gradually cancel the approval of canvas advertising and light box advertising.

With the gradual expansion of the application field of LED display screen, the present presentation forms of LED display screen are gradually enriched and diversified. Many local tyrants use outdoor LED advertising screen to express their feelings, celebrate their birthday, and publish some blessings. This form is gradually accepted by people. Due to the high cost of outdoor LED advertising screen advertising, it is difficult for ordinary people to pay for it. त्यसैले, this other way of celebration has gradually become unique to local tyrants To be able to attract a large number of citizens and netizens in a very short period of time.

For some fans who are crazy about following the stars, this method has attracted their attention. Many local fans will contract many outdoor LED advertising screens on the birthdays and concerts of some stars. Next, let’s take a look at what kind of contracts have been invested in this year.

In May this year, a news spread on the Internet that Lu Han went to Hefei to record the program “I’m going to school”. Fans who love him have done something unimaginable, that is, they spend a lot of money to buy led advertisements to express their love to Lu Han. The outdoor LED advertising screen is almost full of the whole building. The words “Lu Han, I love you” are clearly displayed on it, which is very eye-catching. Soon the news spread quickly on the Internet, causing numerous netizens to pay attention to comments. “Netizens are really rich, and I just don’t want to be rich.

LED advertising screen

साथै, on Zhang Yixing’s birthday, Zhang Yixing’s fans all over the country contracted LED large screens to offer their blessings to Yixing. The local tyrant fans can’t help but be astonished!

In fact, there are not a few cases of using LED display screen to promote the blessing of stars in recent years, but what I have to admire is that the fans are really local tyrants!

LED display screen is popular in the field of outdoor advertising, many businesses and enterprises use the super large outdoor LED advertising screen to carry out a variety of publicity. Especially in the commercial streets, squares and representative buildings in some well-known cities, the amount of advertising investment of LED display screen is amazing, and the corresponding advertising cost is also a huge sum of money, but for some advertising investors, this is indeed an excellent opportunity for publicity.

near 40 degrees high temperature, is the LED full-color display still working normally?” we have to sigh how important it is to make a good heat dissipation solution for the customer’s LED display screen! Here, we recommend wall mounted and column mounted cooling solutions.

First, the explanation of common heat dissipation methods

1. Air hydrodynamics, using the shape of lamp shell to produce convection air, is the lowest cost way to strengthen heat dissipation.

2. Thermal conductive plastic shell, which is filled with thermal conductive materials during injection molding, increases the thermal conductivity and heat dissipation capacity of the plastic shell.

3. Aluminum fin, which is the most common way of heat dissipation, is used as a part of the shell to increase the heat dissipation area. [large electronic display screen]

4. The surface radiation heat treatment, the lamp shell surface to do radiation heat treatment, the simple is to paint radiation heat dissipation paint, can take the heat away from the lamp shell surface by radiation.

2. Wall mounted and column mounted cooling solutions

If the installation method of LED display screen is column, it is better to use fan for heat dissipation. The fan is installed on the aluminum plastic plate on the back of the large screen, and it is better to lean upward to make the form of louver, so that the rain water will not enter the display screen when it rains. If it is a double column, a few blinds should be opened in the middle of the double column. The Baiye window is the air inlet, and the fan above is the exhaust port. In this way, complete air convection is formed and the heat dissipation effect is better.

2. [vehicle LED display] if the installation position of LED display is close to the wall, it depends on how much the LED display can protrude. If it can protrude one meter from the wall, it is recommended to select the fan according to the area, and the fan installation position should be arranged above the side of the screen. If the LED display screen purchased by the customer is p16 outdoor full-color LED screen with an area of 80 वर्ग मीटर, six axial-flow fans with a diameter of about 600 mm should be selected. Special attention should be paid to ensure that the fan is pumped out and equipped with protective net, so as to prevent the technicians repairing the display screen from sucking in clothes and causing personal injury. साथै, the air outlet of the fan on the outside aluminum plastic plate should be installed with aluminum alloy blinds, which can achieve the waterproof effect.

The full-color LED display screen hanging on the wall can also be installed with air conditioner. It is necessary to ensure that the host of the air conditioner is placed in a position, which does not affect the overall appearance of the wall. The selection of air conditioning is required. साधारणतया, 1.5p, 2p and 3P air conditioners are used most, and the air conditioning calculation of 12 square 1p air conditioning in northern cities and 9 square 1p air conditioning calculation in southern cities are adopted. If the area of LED outdoor display screen is relatively large, the air conditioner will be directly customized by the manufacturer. If the area is not large, you should go to the exclusive store to buy it. यद्यपि, the display panel cooling air conditioner has the function of calling compensation.

Different applications determine the different driving modes of LED display screen. In a certain display area, the ratio of the number of lines lit at the same time to the number of lines in the whole area is called scanning mode; indoor single and double color scanning is generally 1 / 16 स्क्यानिङ, indoor full-color scanning is generally 1 / 8 स्क्यानिङ, outdoor single and double-color scanning is generally 1 / 4 स्क्यानिङ, outdoor full-color scanning is generally static scanning.

हाल, there are two driving method of LED display screen in the market: static scanning and dynamic scanning. Static scanning can be divided into static real pixel and static virtual, and dynamic scanning can also be divided into dynamic real image and dynamic virtual image; the drivers are generally hc595 made in China, mbi5026 in Taiwan, and TB62726 in Toshiba of Japan. साधारणतया, there are & nbsp; 1 / 2 & nbsp; स्क्यानिङ, 1 / 4 स्क्यानिङ, 1 / 8 scanning and 1 / 16 स्क्यानिङ.

उदाहरणका लागि: a commonly used full-color module pixel is & nbsp; 16 * 8 & nbsp; (2R1G1B); if the mbi5026 & nbsp; driver is used, the module uses:

16 * 8 * (2 + 1 + 1) = 512 & nbsp; and mbi5026 ; 16 bit chip, 512 / 16 = 32

If 32 mbi5026 chips are used, it is static virtual

If 16 mbi5026 chips are used, it is dynamic 1 / 2 scan virtual

(3) if 8 mbi5026 chips are used, it is a dynamic 1 / 4 scan virtual LED display screen

If two red lights on the board are connected in series

(4) संग 24 mbi5026 chips, it is a static real pixel

(5) संग 12 mbi5026 chips, it is a dynamic 1 / 2 scan real pixel

संग 6 mbi5026 chips, it is a dynamic quarter scan real pixel

In the LED display screen, the scanning modes are 1 / 16, 1 / 8, 1 / 4 र 1 / 2 स्थिर. How to distinguish? One of the simplest ways is to count the number of LEDs in the unit board and the number of 74HC595.

How to calculate: the number of LEDs divided by the number of 74HC595 and then divided by 8 = a fraction of the scan

Real pixel and virtual pixel are corresponding: in simple words, real pixel screen refers to the red, green and blue light emitting tubes that constitute the display screen, and each of them only participates in the imaging of one pixel in order to obtain enough brightness.

The virtual pixel uses software algorithm to control the light emitting tube of each color, and finally participates in the imaging of multiple adjacent pixels, so that the larger resolution can be achieved with fewer lamps and the display resolution can be increased by four times. [large electronic display screen]

The dot spacing is one of the important technical parameters of LED full-color display. What is the dot spacing? How to select the LED full-color display according to the point spacing? This is the question of many friends, and the following are the answers of technical engineers

What is point spacing?

The distance between two pixels reflects the pixel density, which is the physical attribute of the display screen; the information capacity is the unit of information carrying capacity displayed at one time of pixel density per unit area. The smaller the distance between points, the higher the pixel density, the more information capacity per unit area can be displayed at one time, and the closer the suitable viewing distance is. The larger the distance between points, the lower the pixel density, the less information capacity per unit area, and the farther the distance suitable for viewing.

How to select dot spacing of P3 LED full color display पर्दा?

The selection of dot spacing of LED full-color display screen is related to two factors: [एलईडी डिस्प्ले स्क्रिन]

First, the sight distance of LED full-color display screen

The position of the display screen and the distance people usually stand at is only an important factor to determine the distance between points when selecting led full-color display screen.

साधारणतया, there is a formula for the best visual distance = point spacing / (0.3 ~ 0.8), which is a rough range.

उदाहरणका लागि, for a display screen with a dot spacing of 16mm, the best visual distance is 20-54m. If the distance between the stations is closer than the minimum distance, the pixels on the display screen can be distinguished. If you stand far away, the human eye will not be able to distinguish the detailed features. (we aim at normal vision, excluding myopia and hyperopia). In fact, this is also a rough figure.

For outdoor LED full-color displays, P10 or p12 are generally used for the short distance, and p16 or P20 are used for the farther ones. For indoor display screens, P4 ~ P6 are generally available, and p7.62 or P10 are used for remote led full-color displays.

Second, the total number of pixels in LED full-color display.

For video, the basic format is VCD, संकल्प 352 * 288, DVD format 768 * 576. त्यसैले, for the video screen, we suggest that the minimum resolution should not be less than 352 * 288, so that the display effect is good enough. If it is lower, it can be displayed, but not better.

यद्यपि, for the single and double primary color LED full-color display screen which mainly displays text and pictures, the resolution requirement is not high. According to the actual size, the minimum display of 9 font size can be determined according to your text amount.

त्यसैले, the smaller the dot spacing, the higher the resolution and the clearer the display. यद्यपि, we should also consider the cost and demand, application scope and other factors.

Different applications of LED display determine the different driving modes of LED display screen. In a certain display area, the ratio of the number of lines lit at the same time to the number of lines in the whole area is called scanning mode; indoor single and double color scanning is generally 1 / 16, and indoor full-color is generally 1 / 8; स्क्यान गर्दै, outdoor single and double color is generally 1 / 4 स्क्यानिङ, outdoor full-color is generally static scanning.

हाल, there are two driving modes of LED display in the market: static scanning and dynamic scanning. Static scanning can be divided into static real pixel and static virtual scanning, and dynamic scanning can also be divided into dynamic real image and dynamic virtual device. The driving devices are generally hc595 made in China, mbi5026 in Taiwan, and TB62726 in Toshiba of Japan, which generally have & nbsp; 1 / 2 & nbsp; respectively; स्क्यान गर्दै, 1 / 4 स्क्यानिङ, 1 / 8 स्क्यानिङ, 1 / 16 स्क्यानिङ.

उदाहरणका लागि: a commonly used full-color module pixel is & nbsp; 16 * 8 & nbsp; (2R1G1B); if the mbi5026 & nbsp; driver is used, the module uses:

16 * 8 * (2 + 1 + 1) = 512 & nbsp; and mbi5026 & nbsp; is & nbsp; 16 bit chip, 512 / 16 = 32

If 32 mbi5026 chips are used, it is static virtual [LED full color screen]

If 16 mbi5026 chips are used, it is dynamic 1 / 2 scan virtual

(3) if 8 mbi5026 chips are used, it is dynamic & nbsp; 1 / 4 scan virtual

If two red lights on the board are connected in series

(4) संग 24 mbi5026 chips, it is a static real pixel

(5) संग 12 mbi5026 chips, it is a dynamic 1 / 2 scan real pixel

संग 6 mbi5026 chips, it is a dynamic quarter scan pixel [large electronic display screen]

On the LED screen, the scanning modes are 1 / 16, 1 / 8, 1 / 4 र 1 / 2 स्थिर. How to distinguish? One of the simplest ways is to count the number of LEDs in the unit board and the number of 74HC595.

[manufacturer of LED electronic display screen]

In today’s media society, images have gradually replaced words and become a social necessity of living vividly. As a new media advertising form, LED advertising also relies on visual images to spread information and attract audience’s purchase desire through image expression.

For different customer groups, advertisers can put LED display screen with appropriate area in different space to maximize the communication effect of advertising, which makes the visual communication form of LED advertising become rich and colorful.

Compared with other advertising methods, outdoor LED display has many excellent performances.

Superior location

द LED advertising screen is usually located in a crowded area. Large size and gorgeous pictures can create a stronger visual impact. In the era of information explosion, this unique form of realization is often easier to stand out from the overwhelming advertising, effectively realize the information communication with the audience, and achieve the purpose of brand image and public information dissemination. [LED full color display screen]

As outdoor advertising is usually located in the busy road section with huge traffic flow, it is regarded as an important means of enterprise brand and image publicity by many businesses.

यद्यपि, with the promotion of high-definition and 4K technologies, the definition of outdoor display screen is constantly improved, which can provide larger size options. This makes the position of LED display in outdoor advertising industry is increasingly recognized by the market.

Information is available 24 hours a day

LED display screen has its own energy-saving and environmental protection features, and can support the 24-hour uninterrupted broadcast of information dissemination needs. Moreover, it has excellent performance of waterproof, lightning protection and anti-seismic, which can meet the application requirements of harsh outdoor environment. With its high brightness performance, the display effect is not easy to be affected by the environment, so it can ensure the effect of outdoor communication.

It can be used as a display window of city image

साथै, compared with TV advertisement, outdoor LED screen can also broadcast public welfare content such as city propaganda film, so it is not easy to be disgusted by the audience, and its acceptance rate is significantly higher than that of traditional TV advertisement.

एउटै समयमा, it can beautify the city image, enrich people’s spare time life, and become the display window of brand image and city image.

LED advertising screen has become one of the fastest growing markets in the global advertising industry. It has become the first advertisement in Asia. This huge business opportunity has attracted worldwide attention.

हाल, more and more LED displays enter the interior, especially in large hotels and supermarkets. So big

In the indoor environment, द large-scale full-color display screen with an area of more than 5m2 mainly includes ordinary rear projection, DLP (digital liquid crystal rear projection) and LED display

There are three options on the screen.

rear projection displays have the advantages of small pixels and high definition, while the disadvantages are low brightness, small viewing angle and short lens lamp life (only a few thousand)

घण्टा). The advantages of plasma splicing are also small pixels, उच्च परिभाषा, the disadvantage is that there is seam, the minimum seam can be up to 1 mm.

Rear projection and plasma display are suitable for close viewing.

&The advantages of LED display screen are high brightness and no seam. The disadvantage is that the pixel particles are coarse and the definition is low. Commercial indoor

The highest density of color LED display is P4, that is 62500 पिक्सेल / m2. LED display screen is suitable for viewing indoor places with a long distance.

when selecting LED indoor display screen, the following aspects should be considered. [LED display manufacturer]

① real pixels and virtual pixels. Like the outdoor full-color screen, the number of pixels of indoor full-color screen is also divided into real pixels and virtual pixels.

② die. As with the outdoor full-color screen, it is generally recommended that the blue tube and green tube of indoor full-color screen should adopt the core of SLM, and the red tube should be used

The tube core of Guanglei or Guangjia. It is recommended to use Nippon and Cree for high-end products.

③ package form. The LED surface forms of indoor full-color LED display include single lamp, sub surface sticker, three-in-one surface sticker and three in one surface sticker

Several, the appearance is not the same. The advantages of surface mount package are large viewing angle, good luminous consistency and easy automatic welding processing. It is full-color LED

Screen mainstream products, but now the price is relatively high; single light angle of view is relatively small, brightness is slightly higher, the price is lower. In fact, sub surface post is also single

A kind of lamp. Both single lamp and sub surface sticker are relatively cheap and are a transitional product.

④ density. Due to the high heat output of indoor full-color LED chip and the high density of control circuit, the spot density of commercial full-color screen is now very high

We can’t do it very well. There are mainly P5, P6, p7.62, P8, P10 led screen.and so on.

⑤ drive mode. The driving mode of indoor full-color LED display screen is constant current drive and dynamic scanning mode (mainly 1 / 4, 1 / 8)

And so on). In the case of the same die, the circuit used for quarter scan is more and the brightness is higher.
