As a high-tech product, after more than 20 years of market development, LED display can not only effectively transmit information that benefits the people, but also bring unparalleled audio-visual enjoyment to the audience, playing an important role in people's daily life. essential role. For example, the LED display driver IC plays an important role in the high-quality display quality of the LED display. The role of the driver IC in the LED display.

   The dedicated driver chip for LED display refers to the driver chip specially designed for LED display according to the luminous characteristics of LED. The maturity of LED display driver IC technology has brought a qualitative leap in the display effect of LED display. With its large output current and constant current, LED display can be applied to various occasions with high current and high image quality. , which directly promotes the development of the form and application field of LED display content towards a more diverse direction.

  Technology leads the future to help the industry achieve innovation and high quality

  The LED display driver IC is a key component. It is like the central nervous system of the human brain, which is in charge of the body movements of the whole body and the operation of the brain's thinking consciousness. The performance of the driver IC determines the broadcast effect of the LED display screen, especially in the application of small-pitch LED display screens, in order to ensure the comfort of the user's eyes for a long time, low brightness and high gray have become a test of the performance of the driver IC. In particular, the main standards make people's requirements for LED display driver ICs more stringent.

  The LED display driver IC makes more effective use of the micro-LED ultra-fine pitch display light board space, and the high integration function can effectively reduce the layout space and the number of components; in addition, in terms of picture quality performance, low brightness and high stability It has always been the key to dominate the viewing distance and display effect. The average constant current drive of a single color can be as low as 15uA, and the gray level can reach 16bit, which makes the contrast and uniformity of the display screen more delicate, and can also achieve energy saving and low power consumption. Effect.

  In recent years, domestic LED display driver IC technology has also made rapid progress. With the advancement of LED display driver IC technology, the resolution of small-pitch LED displays has been greatly improved, and the pixel center distance of indoor high-density LED displays has been greatly improved. Continuous breakthroughs have been made, and now we have entered the era of 0.X mm.

  At the same time, as the demand for terminal display continues to rise, the display carrier can also be described as bringing forth new ones. For example, micro-LED has become the focus of attention in the display industry. Micro-LED has high brightness, high efficiency, low power consumption, ultra-high resolution and Color saturation, long service life and other characteristics. Today's LED display driver ICs on the market can realize the vision of driving micro-LEDs and make the picture quality more refined.

  Two new trends of development: energy saving and integration

  LED display driver IC plays a vital role in promoting the development of LED display. As a green energy, energy saving is the eternal pursuit of LED display, and it is also an important criterion for considering the performance of driver IC. In the research and development process, while effectively reducing the constant current inflection point voltage, and then reducing the traditional 5V power supply to below 3.8V, the operating voltage and operating current of the driver IC are reduced by optimizing the IC algorithm and design.

  The LED display application technology and scene are constantly updated iteratively, which brings many challenges to the driver IC. The LED display driver IC has made great breakthroughs in technology, which can help the good development of the LED display industry, which will make us more and more in the future. Impressed.

  In addition, product integration will also become an important development trend of LED display driver ICs. With the rapid decline of the pixel pitch of LED displays, the number of packaged devices to be mounted per unit area has increased geometrically, greatly increasing the drive area of the module. component density. Such a crowded arrangement of components can easily cause problems such as poor soldering and reduce the reliability of the module. Less usage of driver IC, larger wiring area of PCB, and the demand from the application side make the driver IC have to embark on a highly integrated technical route.
