Mini-LED backlight technology is divided into two mainstream technologies: AM Mini-LED and PM Mini-LED. AM refers to Active matrix, that is, active matrix drive. PM refers to passive matrix driver, which is a relatively mature Mini-LED backlight technology solution currently on the market.
Compared with PM, AM driving method has more advantages in image quality, display fineness, contrast, power consumption, etc., and AM mode can control the light source to continuously emit light, so there is no screen flicker and it is more eye-friendly. Due to the increasing market demand for high-end display products with high partitioning, AM Mini-LED backlight technology with better picture quality and precise control advantages has now entered a stage of rapid development.

Tianma has previously laid out the application of Mini-LED backlight technology in automotive applications, providing diversified Mini-LED backlight display solutions to automotive customers at home and abroad. Among them, the existing display solutions have been commercialized for large automotive customers and entered the mass production stage. At the same time, Tianma announced the layout of automotive AM Mini-LED backlight technology and continues to optimize existing automotive We provide screen display solutions and actively promote project cooperation with customers.

IT House learned that AM Mini-LED backlight technology can make every Mini-LED Each pixel can be driven to emit light continuously and independently to facilitate individual control of each light source, which means more precise and delicate local dimming (Local Dimming) can be performed. In other words, compared with traditional LCD screens of the same size, LCD screens using AM Mini-LED backlight technology have more advantages in important display parameters such as brightness, contrast and picture fineness, and have better display performance. < p data-vmark="22b2" microsoft="" text-align:="" text-indent:="">AM Mini-LED technology can also achieve better display effects with high brightness and high contrast, making the display quality more delicate and effectively reducing screen flicker. At the beginning of the year, Tianma exhibited a 12.3-inch AM Mini-LED automotive display at CES 2023. Its peak brightness can reach 1500nits and its dynamic contrast ratio exceeds 1,000,000:1. At the same time, the no screen flicker can effectively reduce the driver’s eye fatigue and provide a safer driving environment.

In addition, compared to conventional LED backlights, AM Mini-LED has more advantages in reliability and lifespan. It can also achieve active control of individual light sources and reduce the power consumption and heat of the screen by reducing the number of LEDs that are lit.
