The technical issues that have always plagued the LED industry
2024-12-12
Static electricity damage problem
Since 1998, The LED display industry has been continuously improving its formal lead packaging technology for over 20 years, but so far no company has promised to prevent electrostatic discharge (ESD) damage to lamp beads at 2000V
Lamp bead failure rate issue
From 2012 to 2019, it took the LED display industry 7 years to perfect the assembly components. But there is no LED packaging manufacturer in the industry that can promise customers a 20PPM LED bead failure rate
Heat dissipation and power consumption issues
Since 2001, The LED display industry has been working for 20 years without solving the problems of high brightness, heat dissipation, and power consumption of indoor SMD light beads above 3500CD.
To solve the above industry problems, it is necessary to introduce:
Inverted chip technology, common cathode packaging technology, and common cathode driving technology

LED display gray scale identification level and brightness identification level test

LED display gray scale identification level and brightness identification level test
ALISEN specializes in commercial displays
The grayscale level of ALISEN LED displays depends mainly on the number of A/D conversion bits of the system. Of course, the system's video processing chip, memory and transmission system should provide the appropriate number of bits to support. Currently ALISEN domestic LED display mainly uses 8-bit processing system, that is, 256 (28) levels of gray scale. Simple to understand is from black to white there are 256 kinds of brightness changes. Using RGB three primary colors can constitute 256 × 256 × 256 = 16777216 kinds of colors, that is, usually referred to as 16 trillion colors.ALISEN international brand display mainly uses 10-bit processing system, that is, 1024 levels of grayscale, RGB three primary colors can be composed of 1.07 billion colors.
Although the gray scale is the determining factor in deciding the number of colors, it is not that the larger the better without limit. Because the resolution of the human eye is limited, and then the increase in the number of bits of system processing will involve the system video processing, storage, transmission, scanning and other aspects of the change, the cost of a sharp increase in cost-effective rather than decline. Generally speaking, civil or commercial grade products can be used 8-bit system, broadcast grade products can be used 10-bit system.
ALISEN Brightness identification level:
The brightness discrimination level of ALISEN LED display refers to the brightness level between the blackest and whitest images that the human eye can distinguish.
As mentioned earlier, some gray levels are very high and can reach 256 levels or even 1024 levels. However, due to the limited sensitivity of the human eye to brightness, and can not fully recognize these gray levels. That is to say, there may be many adjacent levels of grayscale human eyes look the same.
Moreover, the eye's ability to recognize these levels varies from person to person. For LED display, the human eye to recognize the level is naturally the more the better, because the image displayed is, after all, for people to see. The more luminance levels the human eye can distinguish means the larger the color space of the display and the greater the potential to display rich colors.
Brightness identification level can be tested with special software, the general display can reach more than 20 levels even if it is a better level.

What are the scenarios of indoor small-pitch led display applications?
With the continuous development and improvement of LED technology, indoor LED display, especially small pitch products with its seamless splicing, high refresh rate, high definition, low energy consumption, long life and other advantages are increasingly favored by the market. So what are the common application areas and use scenarios of indoor small pitch led display?
1, live room, TV studio
Live studio, TV studio video background applications, the anchor background video wall is the most typical, live room, studio on the display panel color temperature, brightness, gray scale, perspective, contrast, refresh rate and other technical indicators requirements are quite demanding. Small pitch led display in the technical indicators can meet the application of such scenes, and LED display because of no slit, unit size is small, can easily meet the internal arc dance design, in contrast, color and other aspects is better than other panels, so the broadcasting application will be an important territory of high-definition LED.
2、Corporate meeting room
Small pitch led display is very suitable for application in the company enterprise conference room video conferencing system display terminal, conference room configuration small pitch led display can not only enhance the corporate image of the company, more enhance the conference effect.
