WinCE.NET系统下黑白LCD的应用

为了降低智能手持终端设备显示部分的功耗,对基于WinCE．NET探作系统的多种单色液晶屏方案进行研究,设计了采用屏幕拷贝方式巧妙实现彩色向单色转化的简单、有效方法．TNS-G320200FTDLY-1W型LCD为例,介绍了显示器件的硬件连接、软件驱程及屏幕拷贝机制中位图的色彩和坐标变换算法设计．经过对程序代码进行优化后,进一步降低了屏幕刷新响应时间,完全能够满足应用的要求．该方案在铁路GSM-R编组站手持移动终端设备研制中得到了成功应用．

Implementation of Mono LCD in WinCE.NET System

A solution of implementing mono LCD in Windows CE.NET,as a substitution of color LCD,is put forward to reduce to display power consumption of intelligent handset in application-specific mobile communica- tion.Several possible solutions are compared and an optimum one is eventually chosen as a simple and effective solution,which creatively uses screen-copy mechanism to convert dispay data from color to mono.Taking LCD module TNS-G320200FTDLY-1W as an example,hardware interlacing,driver developing,algorithm of color convemtion and coordinate coversion in the screen-copy mechanism are expanded.To meet the requirements of the application,codes are optimized to reduce the refreshing latency of the screen.This solution has been ap- plied successfully in the development of mobile handset in GSM-R railway marshalling station.
