The influence of LED lamps on the quality of full-color LED display screens

Posted on March 9, 2024March 9, 2024 by Hytedisplay

Everyone knows that full-color LED display screens are composed of LED lamps in three colors: red, green, and blue. LED lamps are the most important raw material for LED screens, and the quality of LED lamps directly determines the quality and display ability of the LED screen. Choosing different LED beads will result in varying brightness, color, and lifespan of the LED screen.
For full-color LED displays, LED beads are the most critical component, and the quality of LED beads plays a crucial role in determining the quality of LED displays.

Firstly, Nationstar leds are the most commonly used in the entire LED full-color display, with thousands or even tens of thousands of LED beads per square meter.
Finally, LED beads directly determine the performance and color saturation and clarity of full-color LED displays.
The important indicators of LED bead quality mainly include:
1、 Full color LED display brightness
The brightness of LED beads determines the brightness of full-color LED displays. The higher the brightness of LED beads, the greater the margin of current usage, which is beneficial for saving power and maintaining the stability of LED beads. LED beads have different angle values. When the chip brightness is set, the smaller the angle, the brighter the LED, but the smaller the viewing angle of the display screen. Generally, LED beads at 100-110 degrees should be selected to ensure sufficient viewing angle for full-color LED displays.
2、 Full color LED display screen failure rate
LED display screens are composed of tens of thousands or even hundreds of thousands of red, green, and blue LED beads. The failure rate of lamp beads will not exceed one in ten thousand even after aging for 72 hours.
3、 Attenuation characteristics of full-color LED display screens
The brightness of LED beads will gradually decay with increasing usage time. The attenuation rate of LED bead brightness is related to LED chips, auxiliary materials, and packaging processes to a certain extent. Generally speaking, after a 1000 hour, 20 milliampere ambient temperature illumination test, the attenuation of red LED beads should be less than 7%, and the attenuation of blue and green LED beads should be less than 10%. The consistency of red, green, and blue attenuation has a significant impact on the white balance of full-color LED displays in the future, which in turn affects the display fidelity of the display screen.
4、 LED display screen anti-static ability
Due to the fact that LED beads are semiconductor devices and are sensitive to static electricity, they are prone to electrostatic failure. Therefore, anti-static ability is crucial for the lifespan of LED displays. Generally speaking, the failure voltage of the human electrostatic mode test for LED beads should not be lower than 2000V.

In order to help more customers use LED screens more proficiently and effectively, we have summarized some knowledge that must be considered and understood in the use of LED screens. Users who are not very proficient in using LED screens can take it seriously. After reading this article, I believe you will definitely gain something.

Factors that must be considered when using LED screens:
1. Consider the screen area that the user’s site can allow
(1) The relationship between effective line of sight and actual site size;
(2) Pixel size and resolution;
(3) Estimating the area based on units;
(4) The installation location and environment of the display screen;
(5) Space for mechanical installation and maintenance of the screen body;
(6) The influence of screen tilt angle on distance.
2. Users need to achieve the expected playback effect
(1) Text display: Depending on its text size and resolution requirements;
(2) Normal video display: 320 x 240 dot matrix;
(3) Digital standard DVD display: ≥ 640 × 480 dot matrix;
(4) Complete computer video: ≥ 800 × 600 dot matrix;
(5) The customer designs the display resolution themselves;
3. Environmental brightness affects screen brightness
The general brightness requirements are as follows:
(1) Indoor:>800CD/M2
(2) Half indoor:>2000CD/M2
(3) Outdoor (facing south and north):>4000CD/M2
(4) Outdoor (facing north and south):>8000CD/M2
4. Brightness requirements for red, green, and blue in terms of white composition
Red, green, and blue contribute differently to the quality of white. The fundamental reason is that the retina of the human eye perceives different wavelengths of light differently. After extensive experimental verification, the following approximate proportions have been obtained for reference design:
① The simple red green blue brightness ratio is 3:6:1
② The precise red green blue brightness ratio is 3.0:5.9:1.1
5. High end full-color display screens require pure green tubes
In the actual production of LED display screens, three primary color LED chips with high luminous efficiency and the ability to obtain rich and bright color display should be selected, so that the area of the color triangle in the chromaticity chart is as close as possible to the tongue shaped spectral color curve, in order to meet the rich colors and emit sufficient brightness. The top of the tongue shaped curve is 515nm wavelength light. Therefore, high-end LED display screens choose pure green color LED chips with wavelengths close to 515nm, such as 520nm LED tubes with a wavelength of 525nm or 530nm.
6. How to calculate the brightness of an LED single tube under clear requirements for brightness and point density?
The calculation method is as follows: (Taking two red, one green, and one blue as examples)
Red LED brightness: brightness (CD)/M2 ÷ points/M2 × 0.3 ÷ 2
Green LED brightness: brightness (CD)/M2 ÷ points/M2 × 0.6
Blue LED brightness: brightness (CD)/M2 ÷ point

The LED rental display screen market is just starting to take off and is a niche market that is not very promising. LED rental display screens have high requirements for the box, high design and mold costs, and low market demand, so most companies are unwilling to undertake such business. Some companies with foresight and advantages in structural design have begun to invest in this area (such as Big Eyes, Guangxiang, and Leiling, which have become synonymous with renting LED display screens).

Due to the rent (such as P6) being above 600 yuan/square meter, the leasing company is not price sensitive when purchasing screens. At this time, the main focus is on the competition between the convenience and aesthetics of die cast aluminum boxes (i.e. structural competition).
LED rental display screens are much more expensive compared to engineering screens, but the good rental income has attracted a large number of young entrepreneurs to invest crazily in display screen rental. For a while, LED rental display screen companies have been booming and thriving.
A P6 LEDLED rental display screen was priced at around 1500 yuan/square meter in 2008, around 1200 yuan/square meter in 2009, around 800 yuan/square meter in 2010, around 500 yuan/square meter in 2011, and by early 2012, most places had dropped to around 250 yuan/square meter. At the same time, in less than a year between the second half of 2011 and the first half of 2012, the number of LED rental screens in China increased threefold. As a result, by 2012… the rent for P6 rental screens was around 150 yuan.

Due to the huge market demand, almost all enterprises with sales exceeding 20 million are producing LED rental display screens themselves. With a broad perspective, companies such as Leiling, Guangxiang, Redio, Shijue, and Huiming have accumulated professional teams in the design, production, and sales of LED rental screens, forming their own advantages in box design; 2. Although companies such as Zhouming, Lianjian, Ruituo, Mairui, Yishida, Liade, and Lijing do not specialize in producing rental screens, they have also designed corresponding rental boxes based on their scale advantages and gained a certain share of the rental market business; 3. Kress, Xincai, Huijiarui, Tongpu, Decai, Haobo, Kemeixin and other companies do not have rental boxes, but their small scale has a price advantage and they also sell a certain amount of LED rental display screens.
We firmly believe in winning customers with product quality and brand benefits, focusing on the challenges and pressures that customers are concerned about, providing competitive LED display solutions and services, and continuously creating maximum value for customers. Gathering industry elites, possessing a large number of experienced and highly skilled technical and management talents, and having an excellent sales team; By relying on sophisticated testing instruments and equipment, a complete product quality control system has been established, covering the stages of research and development, production, installation, and debugging, as well as final inspection and passing of the factory; Relying on strong integration and team collaboration capabilities, Leiling Display has established strategic partnerships with domestic and foreign LED display raw material suppliers and sellers, achieving resource integration, complementary advantages, and efficient collaboration for modern enterprises; We adhere to the business policy of “customer first, quality first, reputation first, abide by contracts, and keep promises”, and work together with people from all walks of life at home and abroad to create a better future.

Feb

In terms of fire prevention technology, led transparent screen mainly depends on the fire prevention raw materials and box process of transparent screen. Refractory raw materials include transparent screen inner wire, power supply, fireproof materials, plastic kit and other aspects: in most transparent screen applications, the larger the area, the greater the power consumption, and the higher the power on stability of the wire.
Among many wire rod products, the safety and stability of wire rod can be ensured only by adopting wire rod meeting the requirements of national standards. There are three requirements: the wire core is the conductive carrier of copper wire, the cross-sectional area tolerance of wire core is within the standard range, and the insulation and flame retardant performance of core-clad adhesive layer meet the standard. Compared with ordinary copper-clad aluminum wire core, the cross-sectional area of wire core is small, and the grade of insulation rubber is not enough, The charging performance is more stable and is not prone to short circuit.
UL certified power products are also the best choice for similar products. The effective conversion rate can ensure the safety and stability of power load, and can work normally under the hot external environment; 3. Another important component of LED transparent screen fireproof raw materials is plastic bag.
The plastic kit is mainly used as the material for the bottom shell of the unit module mask. The main raw material is flame retardant PC glass fiber material, which not only has flame retardant function, but also can be used for a long time at low temperature without deformation and embrittlement. Indoor materials will affect the fire prevention effect. The external configuration and design are also very important, but the external configuration mainly focuses on the surrounding heat dissipation.

How to choose a small pitch LED display advertising wall

Posted on February 27, 2022October 18, 2022 by Hytedisplay

Feb

When purchasing LED displays, the precautions for choosing small spacing LED displays: users should consider their own cost, demand, scope of application and other factors. Before buying a small spacing LED display, decide whether you really need a small spacing. It should be decided according to the actual situation.
1、 The prerequisite is “low brightness and high gray”.
As a small spacing LED screen of the display terminal, we must first ensure the viewing comfort, so when purchasing, the primary consideration is the brightness. Relevant research shows that as an active source, LED has twice the brightness of passive light (projector and LCD) in terms of human eye sensitivity. In order to make the eyes look more comfortable, the brightness range of small spacing LED screen can only be between 100cd m2 and 300cd .
2、 When choosing point spacing, we should pay attention to the balance of “effect and skill”
Ordinary LED screens want to get good visual effects. Some people can only see the sight distance and small spacing LED screens. Users can simply measure P2 through sight distance = sight distance . For example, the viewing distance of P2 small spacing LED screen is about 6m.
3、 Select the resolution and pay attention to the matching with the “front-end signal transmission device”.
The smaller the dot spacing of the low spacing LED screen, the higher the resolution, and the higher the definition of the image. In practice, users want to construct a good LED display system with small spacing. While paying attention to the resolution of the screen itself, they should also consider the matching with the front-end signal transmission products.

Nov

LED display is now more and more widely used. When the application field and installation environment are different, the installation methods of LED display are also different. How to install the LED display? What are the installation methods?

1、 The most common installation method (wall mounted or embedded)
Wall mounted installation is the most commonly used installation method. The LED display will protrude 10 cm or more from the wall. Embedded is that the whole LED large screen is embedded into the wall, and the display plane is at the same level as the wall. These two installation methods are usually used when there is no rain indoors or semi outdoors, and the front maintenance design is generally adopted (i.e. front maintenance design, which is usually assembled by unit plate magnetic suction).
2、 Cantilever or suspension type
This method can be used both indoors and outdoors. Generally, indoor scenes are used at the entrance of passages and corridors, as well as at the entrance of stations, railway stations and subway entrances. Outdoor scenes are used for traffic guidance on highways, railways and expressways.
3、 Column installation (single column and double column)
There are many column installation methods, which are generally used for outdoor billboards, and the single column installation method is suitable for small screens; Double column installation method is suitable for large screen; Closed maintenance channel is suitable for simple box; The open maintenance channel is suitable for all outdoor boxes.
4、 Floor standing and roof type installation method
This method is applicable to indoor and outdoor. Generally, the back wall cannot bear load or the surrounding is open, so it can only be installed vertically on the ground. This installation method is generally thick, because there are no support points around, and all forces are supported at the bottom.

What are the advantages of full-color LED display video wall billboards?

1. It has a wide viewing angle. For the surface paste screen display, it has a viewing angle of more than 110 degrees in the horizontal direction and the same performance in the vertical direction. In many external environments, such a large viewing angle is very advantageous.
2. In terms of light distribution, the brightness of blue, red and green LEDs looks the same from all angles. This can make the full-color LED display screen more perfect to show its playing effect. No matter what angle the viewer can enjoy the best color picture, instead of the traditional direct plug-in lamp bead display screen with large angle deviation, There is a problem of color distortion.
3. In terms of light mixing, due to its three in one chip design structure, the chip body with a very small distance can mix light in the same support cup, that is, the red, green and blue chips form a light bead, which is different from the three chips of ordinary led. In different LED light beads, the three light beads form a light mixing point, and the light mixing performance is poor. If you watch it closely, the watch paste screen display will have a better viewing effect.
4. In terms of contrast, because its structure is three in one, the SMD will be very small. The direct result is that there is a small area of luminous formation and a large area of black area, resulting in a very high contrast of the screen display.
5. In terms of product production, the surface pasted full-color LED display has high automation. It can be produced by full-automatic equipment. It has a high production efficiency and excellence rate. In terms of production links, its quality is better than the traditional LED full-color display with in-line lamps.
6. In terms of the weight of the body, it is very light, which has a great relationship with the material of aluminum alloy used in the box. It is not only light in weight, but also very beautiful. After long-term use, there will be no deformation. It has very high use value for both companies renting products and users’ own purchase.
Although there are various shortcomings in the installation of this full-color LED display, for example, its brightness is lower than that of other products, and its waterproof performance is also worse, in terms of cost performance, this product has excellent performance in many aspects, and its advantages outweigh its disadvantages. It is still worth buying this product.
