The LED display application technology and scene are constantly updated to bring challenges and opportunities for the driver IC

LED display driver chip refers to the driver chip designed specifically for LED display according to the LED light emitting characteristics. The maturity of LED display driver IC technology brings a qualitative leap to the display effect of LED display. With the characteristics of large output current and constant current, the LED display can be applied to various occasions with high current and high image quality. , Directly promoted the display form of the LED display screen and the application field to develop in more directions.

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, 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.

In recent years, the domestic LED display driver IC technology has also been rapid progress. With the progress of LED display driver IC technology, the resolution of small-pitch LED display has been greatly improved, the pixel center distance of indoor high-density LED display. Continuous breakthroughs have now 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.

Develop two new trends: energy saving and integration

LED display driver IC plays an important role in the development of LED display. As a green energy, energy saving is the eternal pursuit of LED display, and it is also an important standard to consider the performance of the driver IC. 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 decline in LED display pixel pitch, 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. The arrangement of such congested 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. The LED display driver ICs have made major breakthroughs in technology in order to help the LED display industry to develop well. In the future, we will let us More impressive.
