摘要
座舱中液晶显示器的背光亮度自动调节功能非常重要,背光亮度直接影响信息的可读性。为了研制高效的能自动调节背光亮度的显示器,通过对相关电路的设计和对单片机定时器和中断器的编程控制,实现了液晶屏亮度的自动和人工调节,使得座舱显示器在各种环境光下都能正常有效的工作。该电路不仅可用于军用显示器还可用于民用显示器。
In cockpit, the automatic regulation of backlight brightness of LCD is very important, because it will influence the information＇s readability directly. To develop a high-efficiency display which can regulate the baeklight brightness automatically,the automatic and manual regulation of LCD are realized by designing the relevant circuit and programming the timer and interrupter of MCU. That can make cockpit display work well in various environment lighting. The circuit can be used not only in military display, but also in civil display.
