现在项目需要,要用到一款友达的“A101VW01 V1”800*480宽屏液晶,看到其有一个引脚是“POL”,注释是Polarity selection ,
Note 3: POL
“POL” value is latched at the rising edge of “LD” to control the polarity of the even or odd outputs.
POL=1: Even outputs range from V1 ~ V7, and Odd outputs range from V8 ~ V14
POL=0: Even outputs range from V8 ~ V14, and Odd outputs range from V1 ~ V7

现在准备使用2440去驱动,但是看了半天2440的TFT接口上并没有这个控制POL的引脚,不知有没有大侠可以告知一下是怎么回事,谢谢!
