摘要
为了使户外显示器能够达到更好的显示效果,户外显示器应具有亮度自动调节功能。将显示器的亮度表示为环境光的3次函数,检测环境光的照度,通过单片机计算和控制显示器的实际亮度,实验表明该方案是可行的,可以为座舱显示器的设计提供参考。
In order to achieve better visualization, outdoor displays should have brightness autoadjustment function. A cubic function of ambient light is used to represent the brightness of display. The ambient light illuminance is detected by a light sensor, and then the actual brightness of display is calculated and controlled by a MCU. The experiments show that this scheme is feasible, can provide a reference for the design of cockpit displays.
