使用直下式RGB LED作为座舱用液晶显示器背光源,并采用背光模块分区技术;通过对背光源驱动电路的设计,使用CAN总线通讯,实现了显示器背光模块的光强根据周围环境光的三原色光强或用户喜好自动或手动调节。该设计能更好地满足座舱内用户的需求。
The use of direct-type RGB LED as a cockpit with liquid crystal display backlight and backlight module partition technology; through the backlight drive circuit design, the use of CAN bus communication, to achieve the display backlight module light intensity according to the ambient light of the three primary light intensity Or user preferences automatically or manually adjusted. The design can better meet the needs of users within the cockpit.
