Shulou(Shulou.com)11/24 Report--

CTOnews.com February 2 news, Tianma Microelectronics announced the launch of a vehicle display backlight solution based on AM Mini-LED technology.

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 drive, which is a relatively mature Mini-LED backlight technology scheme in the market at present.

Compared with PM,AM drive mode, it has more advantages in picture quality display fineness, contrast, power consumption and so on, and AM mode can control the continuous light source to achieve no screen flash, more eye protection. Due to the increasing market demand for high-end display products with high division, better picture quality and accurate regulation and control, AM Mini-LED backlight technology has entered a stage of rapid development.

▲ Mini-LED backlight technology schematic Tianma has previously laid out the application of Mini-LED backlight technology in vehicles, providing a variety of Mini-LED backlight display solutions to on-board customers at home and abroad. Among them, the existing display solutions have realized the commercial application of large customers in vehicles, and have entered the stage of mass production. At the same time, Tianma announced the layout of in-car AM Mini-LED backlight technology, continue to optimize the existing vehicle screen display solutions, and actively promote project cooperation with customers.

▲ 12.3in AM Mini-LED exhibit CTOnews.com learned that AM Mini-LED backlight technology allows each Mini-LED pixel to be driven continuously and independently to help achieve separate control of each light source, which means more precise local dimming (Local Dimming). In other words, in the same size, compared with the traditional LCD screen, the LCD screen with AM Mini-LED backlight technology has more advantages in brightness, contrast and picture fineness, and has more excellent display performance.

AM Mini-LED technology can also achieve a better display effect of high brightness and high contrast, the display image quality is more delicate, and can effectively reduce screen flicker. At the beginning of the year, Tianma displayed a 12.3-inch AM Mini-LED vehicle display on CES 2023, with a peak brightness of 1500nits and a dynamic contrast of more than 1, 000, 14, 000, 000, and 1. At the same time, the non-screen flash can effectively reduce the driver's eye fatigue and provide a safer driving environment.

▲ uses conventional LED backlight display

▲ uses AM Mini-LED backlight display. In addition, compared with conventional LED backlight, AM Mini-LED has more advantages in reliability and life. At the same time, it can actively control a single light source and reduce the power consumption and heat of the screen by reducing the number of LED lighting.
