摘要
机载大尺寸液晶显示器(liquid crystal display,LCD)显示模块具有亮度高和功耗大的特点.为了降低其动态功耗,介绍了一种用于大尺寸机载显示模块的动态背光控制系统.该系统采用发光二极管(light emitting diode,LED)动态背光控制技术,通过对背光的动态调节,提高动态显示效果和达到节能的目的.对系统的硬件电路和软件设计算法进行了详细的介绍,并进行实验验证.结果表明,该系统能够有效地提高机载显示模块的动态显示效果,并显著降低了动态功耗.
Abstract
Large-size liquid crystal display(LCD)modules for airborne applications have the characteristics of high brightness and high power consumption.In order to reduce their dynamic power consumption,a dynamic backlight control system for large-size airborne display modules is introduced.The system adopts light emitting di-ode(LED)dynamic backlight control technology to improve dynamic display effect and achieve energy saving by dynamically adjusting the backlight.A detailed introduction to the hardware circuit and software design algorithm of the system is provided,and experimental verification is conducted.Results show that the system can effectively improve the dynamic display effect of the airborne display module and significantly reduce dynamic power consump-tion.
