How long can a good LED display be used? No one should be able to get an accurate answer to this question, because the purpose is not

In the same way, the working conditions of LED display are very different.

In terms of environment, the indoor temperature difference is small, without the influence of rain, snow and ultraviolet rays; the maximum temperature difference outside can reach 70 degrees, plus wind, sun and rain.

Harsh environment will aggravate the aging of LED electronic display पर्दा, and the working environment is one of the important factors affecting the life of LED display screen. साथै, a good LED chip has the characteristics of attenuation, water vapor permeability and UV resistance

Very strong, so the quality of LED chip is the most important factor affecting the life of LED display. In addition to LED light-emitting devices, the display screen also uses many other peripheral components, including circuit board, plastic shell, र यस्तै

Switch power supply, connector, case, any one of the components of the problem, may lead to the life of the display screen reduced. [LED full color screen manufacturer]

साथै, the production process of the LED display manufacturer is also a key factor to determine the display life. The production process involved in the production of LED display screen includes component storage and pretreatment process, furnace welding process, three prevention treatment process, waterproof sealing process, आदि.

The effectiveness of
process is related to material selection and proportioning, parameter control and operator quality. The accumulation of experience is very important, so one has many years of experience

Experienced LED display manufacturers will be more effective in controlling the production process.

त्यसैले, in order to ensure a longer service life of LED display, it is necessary to analyze the impact of environmental factors on the LED full-color display screen, and select the appropriate one

Appropriate device and manufacturing process are appropriate to ensure the life span. This process includes: life design, process control, reliability verification, and periodic verification

The display screen is maintained and tested.

only by doing a good job of routine maintenance, can we get a very good LED display. सामान्यतया भन्ने हो भने, maintenance and repair are not

Need to do every day, as long as regular maintenance of the display, you can get very good results.

We all know that led electronic display screen is driven by electricity. We can say what effect the product can achieve. On the one hand, it is the quality of the product,

On the other hand, it is not whether the efficiency of the power supply is sustained and stable. So how to improve the driving efficiency of LED power supply? Here are eight tips for you

1. The main current circuit PCB should be as short as possible: the experience and layout of laypcb are nothing, and the fast way is to look at the works of large factories.

2. Optimize transformer parameter design: reduce eddy current loss caused by ringing. This is relatively difficult. First of all, we should master the basic knowledge of electromagnetic and design a reasonable change

Pressure, the most important thing is patience, even if you want to improve the efficiency of 0.5%, also want to try. Reasonable selection of switching devices: This is the balance between cost and performance, what kind of customer requirements, what kind of device to use, but reasonable. as

For efficiency, there is no doubt cool MOS, low VF output diode. If the input EMI part of the optimization design has passed the safety regulations, this part will be more elaborate, mainly experience. [price of LED electronic display screen]

5. Selecting high-efficiency extension structure is the beginning of scheme selection, such as PWM and QR PFM. If the current customers ask for efficiency, they should evaluate it

What kind of extension should be selected.

6. Choosing a good electrolytic capacitor is ignored by many people, and the electrolytic loss is very large.

7. On the premise that the power consumption design of start-up part is efficient, it should be considered that at present, many chips have HV startup pins, and the starting current is getting lower and lower

Point is to understand more about new devices, of course, there are additional circuit lossless start, I think it is not suitable for LED drive.

8. Chip assisted power supply optimization. This point is pointed out in the l6562d application document of St that 15V is the best, but the LED is generally wide voltage output, so

My choice is to add a linear voltage regulator to make the chip work at 15V to reduce the loss.

the above eight tips are summed up in the daily work of liansen optoelectronics, hoping to help the majority of LED manufacturers.

Compared with the traditional advertising products, LED display screen exists more in the outdoor environment because of this situation Installation conditions, running time and other complex issues need to be considered, which requires us to regularly maintain the display screen

Ensure the quality and life of LED display. So how to repair and maintain it? Let’s introduce it to you.

1. Pay attention to the humidity of the surrounding environment of the LED advertising screen, and do not let the articles with moisture enter into the LED advertising screen. If wide on wet led

When the advertising screen is electrified, the internal parts of the LED advertising screen will be corroded by water vapor, which will cause irreparable damage to the LED advertising screen.

2. Try to avoid possible situations, and keep the LED advertising screen away from the screen. On the screen

Line cleaning, but also to gently scrub, as far as possible to reduce the risk of injury. [Shenzhen LED display price]

3. The screen has the most contact with customers, and daily maintenance is also necessary. Regular dust removal and cleaning of the screen can

To improve the display effect of LED advertising screen, increase the influence. The power supply of the screen is also required to be stable, and the grounding protection should be done well. In case of bad weather, strong wind, rainstorm and heavy thunder, the power supply of the screen should be stable,

The screen should no longer be used.

5. The screen interior should be closed to prevent water and other conductive metal objects. LED advertising screen should be placed in good ventilation, dust than

Less in the environment. Large particles of dust will not only weaken the display effect, but also damage the circuit of LED advertising screen.

6. Correct switching sequence of LED advertising screen: ए: turn on the control equipment of the screen first, and then run the control software of the screen,

After stable operation, open the LED advertising screen after power on. बि: Turn off the screen before turning off the computer.

7. The LED advertising screen should be guaranteed to be out of service for more than two hours. In wet and cold weather, at least led should be used every seven days

The ad screen runs once. It is suggested that the LED advertising screen should be turned on more than once a month, and the lighting time must be more than 2 घण्टा.

8. Regularly check the LED advertising screen, and if there is any improper problem, it should be timely reported, repaired and replaced.

please remember that the above 8 items will definitely be of great benefit to you in your daily use of LED display screen. If there are other problems about LED display screen,

Various types of LED display also emerge in endlessly, although the development is fast, but the prospect is not optimistic. The good market prospect of will also attract more competitors. Coupled with the promotion of industrial policies, more capital will enter the LED industry in the future.

यद्यपि, at present, the concentration of domestic LED screen industry is not high, the market share is relatively scattered, and the problem of product homogeneity is prominent, so the enterprise’s anti risk ability is worrying.

Once a large amount of external capital is injected, the current loose brand pattern will be easily disintegrated, and industry reshuffle is inevitable.

profits decline or endanger the survival of enterprises

as we all know, LED industry technology updates rapidly, raw material prices continue to decline, leading to a downward trend in product prices. With more capital in the future

With this injection, more production capacity will be released in a centralized way, which will form a more competitive situation. The domestic market environment with price war practices will eventually lead to enterprises

The decline of profitability even threatens the survival of enterprises.

in the face of homogeneous and low profit market risks, LED display enterprises actively explore new profit growth points and profit models. For the current industry hot

With the highest degree and high profit margin of small space LED display screen, enterprises have been increasing their R & D investment. After the 0.8mm small spacing LED display screen came into being,

At the end of March, 0.7mm small spacing products were also developed, which effectively improved the competitiveness of high-density small spacing products with DLP and LCD splicing technology,

It promotes the small space LED screen to stride forward to indoor application.

LED display market continues to heat up, which brings both opportunities and challenges. In the face of increasingly fierce market competition, LED display enterprises have their own advantages

To explore the survival and development of enterprises. एउटै समयमा, it also brings a signal to the market: industry reshuffle is inevitable, and enterprises need to be far sighted and accurate

Positioning can effectively cope with the coming tide of the industry.

त्यसैले, in response to the wave of led development, each company has made its own moves to cope with different development pressures, and finally hope that the majority of LED.

It can be said that professional development, design and strict production management are essential for the LED display screen.

1. Flatness the surface flatness of LED display screen should be within ± 1mm to ensure that the display image will not be distorted, and local bulge or concave will cause display

There is a dead angle in the visual angle of the display screen. The flatness is mainly determined by the production process.

2. [Shenzhen LED display] brightness and visual angle the brightness of indoor full-color screen should be more than 800cd / m2, and that of outdoor full-color screen should be at least 800 सीडी / m2

1500 सीडी / m2 above, to ensure the normal operation of the display screen, or because the brightness is too low to see the image displayed. The brightness of the main size

It is decided by the quality of LED core.

the size of the viewing angle directly determines the number of screen audience, so the larger the better. The size of the viewing angle is mainly determined by the packaging mode of the die

decision.

3. White balance effect white balance effect is one of the most important indicators of display screen. When the ratio of red, green and blue is 1:4.6:0.16

Will show pure white, if the actual proportion has a little deviation, there will be a deviation in the white balance, generally pay attention to whether the white is blue, partial

Yellow green phenomenon. The quality of white balance is mainly determined by the control system of the display screen, and the tube core also has an impact on the color reducibility. [LED display price

Case]

Color reducibility refers to the color restoration of the display screen, that is, the color displayed on the display screen should keep high

with the color of the playback source

In order to ensure the authenticity of the image.

5. There are * * SEG and dead point phenomenon. Mosaic refers to the small four squares which are usually bright or black on the display screen, which is not only the module necrosis phenomenon, but also the main reason

Because the quality of the connector used in the display screen is not up to standard.

the above five points can help you to make a reference when purchasing LED display पर्दा, but even if the quality is up to standard, please pay attention to the product

 

We all have different opinions on whether the LED display can be used normally and for a long time. यद्यपि, we believe that the quality of the products is one aspect, and the safety of the LED display screen is very important.

The environmental choice of installation is also a very important part.

There are a lot of optical elements in the
Quality led display पर्दा. In the process of using, there will be a lot of dust in the air, and then pass through some small particles

The optical element is the vulnerable part of dust, which is dangerous to the optical element

We can’t look down on it. Sometimes a little dust can bring fatal damage to our machines.

LED electronic display screen currently attaches great importance to the details of the screen, and the details of each project are required to be very high, seamless splicing technology is constantly

Improve, their display effect is very good to ensure the final display effect is perfect.

from the process of using LED electronic display screen, dust protection is also a very important part of the process. How to achieve better dust prevention is led

One of the most important aspects of electronic display technology upgrading. [Shenzhen LED display screen]

too much dust will reduce the brightness of our screen. If the LED electronic display screen is installed in a dusty environment, it is generally dusty

It will reduce the brightness by 30%. If it is serious, it may reduce the brightness of the screen by 70%, so we must think about it in the process of operation

Law to make our system dust less, if there is dust, but also through the correct method to remove as soon as possible. In the screen display, 7200 rpm is generated during the operation of the color wheel. A lot of dust will accumulate

The rotation speed of the color wheel is uneven and the color of the image is shifted.

it is precisely because dust has such a great impact on our whole large screen system that we should pay special attention to the operating environment of LED electronic display screen.

because of this, when we install, we really need to work hard to choose the environment. Only perfect after-sales service

Nowadays, there are many manufacturers and products of LED display screen. When buying LED screen, customers usually go to the manufacturer for inspection, so it is necessary to know the inspection of how to detect LED screen:

visual inspection and hand feeling can be used to detect whether there is a problem with the LED screen. Adhesion of coating: there should be no peeling off.
