LCD背光接口

 

  现在市面上,大多LCD屏都采用了LED背光源。一般情况下,LVDS接口的LCD屏的背光电源,是与LCD屏的工作电源相互独立的,且电源电压也不同,常见的LCD屏的背光电源是DC12V和DC5V。为了方便一部份LCD屏背光电源连接,在ESMARC EVB评估底板上,设置了专用的LCD背光电源及控制信号接口CN21。背光电源及控制信号接口如下表所示:

1 +5.0V DC5V输出,可用于LCD背光电源
2 GND 公共地
3 NC 留空
4 LCD_BH TTL电平LCD背光控制信号,高有效

LCD电阻触摸屏接口

 

  福彩3D走势图绝大多数的LVDS显示屏的触摸屏,都是额外配套了一张触摸板,所以触摸屏的信号线是没有和LVDS显示信号在一起的。为了方便连接这种情况下的LCD触摸屏,在ESMARC EVB评估底板上设置了专用的4线电阻触摸屏接口CN22,它的信号定义如下:
