Description

汽车挡风显示系统及汽车 技术领域
本发明涉及显示技术领域，尤其涉及一种汽车挡风显示系统及汽车。
 背景技术
随着显示技术的发展，液晶显示装置（Liquid Crystal Display，LCD）等平面显示装置因具有高画质、省电、机身薄及应用范围广等优点，而被广泛的应用于各种消费性电子产品，成为显示装置中的主流。
目前市场上的液晶显示装置以光源需求大略分为三类：透射式液晶显示装置、反射式液晶显示装置及透反式液晶显示装置。其中，透射式液晶显示装置以液晶显示面板背面的背光模组作为光源，背光模组发出的光线穿过阵列基板透明的像素电极进行画面显示，透射式液晶显示装置适合使用在弱光环境中，而在强光环境下，背光模组的光强会受到外在光的干扰，影响显示品质，若此时提升背光模组的亮度，对显示品质的提升较小，且功耗增加。反射式液晶显示面板主要是以前光源或环境光作为光源，其阵列基板上设有用反射材料制作的反射电极以对前光源或环境光的光线进行反射实现画面显示，反射式液晶显示装置适合用于环境光较强的场景，但在环境光较弱的场景显示效果不佳。透反式液晶显示装置则是透射式液晶显示装置及反射式液晶显示装置的结合，在阵列基板上既设有反射区，又设有透射区，可以同时利用背光源以及前光源或环境光进行显示。在光线较暗的环境下，主要靠透射模式，也就是利用背光源发出的光线显示图像，在环境光较强的情况下，主要靠反射模式，即利用液晶显示面板内的反射电极将环境光反射而显示图像。
随着汽车行业的发展，车载显示技术越来越引起重视。目前的车载显示屏需要单独的装置，一般设置在仪表板外部的右侧，在车辆行驶过程中，驾驶员需要低头才能观看到显示屏上显示的内容，观看不变且易于造成事故。
 技术问题
本发明的目的在于提供一种汽车挡风显示系统，能够依据环境光的强度及控制指令进入不同的工作模式，适应性强，产品品质好。
