LED display driver IC technology breakthrough

The LED display driver IC is a key component. It is like the central nervous system of the human brain, in charge of the body's physical actions and the mental thinking of the brain. The performance of the driver IC determines the effect of the LED display screen broadcast, especially in the application of small-pitch LED display, in order to ensure the user's eye comfort for a long time, the low-light high-gray becomes a test driver IC performance Especially the main standard, making people more stringent requirements for LED display driver IC. As we all know, the development of LED display technology will dominate the future of the industry. In recent years, the domestic LED display driver IC technology has also made rapid progress. The small-pitch LED display is an important market for the industry, and it is also the market with higher profitability. First, with the progress of LED display driver IC technology, the resolution of small-pitch LED display screens has been greatly improved, and the pixel center distance of indoor high-density LED display screens has continuously made breakthroughs. Now it has entered the era of 0.X mm. .

At the same time, as terminal display requirements continue to increase, the carrier of display can also be described as new. For example, micro-LED has become the focus of attention in the display industry. Micro-LEDs have high brightness, high efficiency, low power consumption, and ultra-high resolution. Color saturation, long life and other features. Nowadays LED display driver ICs on the market can realize the vision of driving micro-LEDs and make the picture quality more exquisite. The LED display driver IC is used more effectively for the micro-LED ultra-small display display panel space. The high integration function can effectively reduce the number of cloth space and components; in addition, the low-brightness and high-stability in the picture quality performance. Has been the key to dominate the viewing distance and display effect, a single color average constant current drive can be as low as 15uA, the number of gray levels can reach 16bit, so that the display screen contrast and uniformity more delicate, but also to achieve energy-saving low power consumption effect.

From the above we can see, LED display driver IC in the development of LED display screen plays a vital role in promoting, as a green energy, energy saving is the eternal pursuit of LED display, but also consider the driving IC performance of an important standard . During the R&D process, the IC operating voltage and operating current are reduced by optimizing the IC algorithm and design while effectively reducing the constant-current knee voltage and further reducing the conventional 5V power supply to below 3.8V.

In addition, product integration will also become an important trend in the development of LED display driver ICs. With the rapid decrease in the pixel pitch of LED display screens, the packaging devices to be mounted on a unit area will increase geometrically, greatly increasing the drive surface of the module. The density of components. With so many devices, the available wiring space for PCBs becomes extremely congested, increasing the difficulty of circuit design. At the same time, the arrangement of such crowded components can easily cause problems such as poor soldering and also reduce the reliability of the module. Drive ICs use less, PCBs have larger wiring areas, and the demand from the application side forces the driver ICs to embark on a highly integrated technology path.

The application technology and scenes of LED display screens are continuously iteratively updated, which brings many challenges to the driver ICs, but we are fully aware that only a solid foundation can be made to help the LED display industry to develop well. Today, LED display driver ICs are There has been a very big breakthrough, but I believe that in the future will make us more eye-catching


In addition, overseas markets are increasingly demanding for LED stage screens. This large market is one of the major driving forces for the development of the internationalization of Chinese screen companies. Many domestic LED screen companies have extended their strategies overseas. In contrast, the overseas market places more emphasis on practicality and perfection from the outside to the outside world. In order to make the overseas stage leasing market a hot spot, domestic LED display companies are increasing overseas. At the same time as the market extension, it will also increase the R&D investment in product technology and quality, ensure the stability of the product, and further better capture the digital dance market of overseas led display screens.


The style of the stage is varied, but the led display undoubtedly becomes the trend of this era. Under the background of rapid economic development in our country, the digital dance market is growing, further stimulating the booming of the LED stage screen and LED stage leasing market, making the led display have dazzling performance in major concerts and large-scale performances. . Although this year's Spring Festival Gala has not disclosed the relevant figures and design information, there is no doubt that it will bring us a visual feast, and what led display will show and breakthrough, let us wait and see.
