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

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

1. Technology leads the future to help the industry achieve innovative and high-quality: LED display driver IC is a key component, it is like the central nerve of the human brain, in charge of the body's movements and the operation of the brain's mind and consciousness. The performance of the driver IC determines the effect of the LED display screen, especially in the application of small-pitch LED displays. In order to ensure the user's long-term eye comfort, low brightness and high gray have become a test of the performance of the driver IC. Especially the main standards make people have more stringent requirements for LED display driver ICs.

The LED display driver IC makes more effective use of the space of the micro-LED ultra-fine-pitch display panel. The high integration function can effectively reduce the 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 the viewing distance and display effect. The average constant current drive of a single color can be as low as 15uA, and the number of gray levels can reach 16bit, making the contrast and uniformity of the display screen more delicate, and it 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 Continuous breakthroughs have been made, and now it has entered the 0.X mm era. At the same time, as the demand for terminal display continues to rise, the display carrier can also be described as new. For example, micro-LED has become the focus of the display industry. Features such as color saturation and long service life. Nowadays, LED display driver ICs on the market can realize the vision of driving micro-LEDs and make the picture quality more refined.

2. Energy-saving and integration are major development trends: LED display driver ICs play a vital role in the development of LED displays. As a green energy source, energy-saving is the eternal pursuit and consideration of LED displays. An important standard for driver IC performance. 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 scenarios continue to be iteratively updated, bringing many challenges to the driver IC. The LED display driver IC has made major breakthroughs in technology to help the good development of the LED display industry. In the future, it will make us more Admiringly.

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