| Abstract: | 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 communication. 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 interfacing, driver developing, algorithm of color converstion 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 applied successfully in the development of mobile handset in GSM-R railway marshalling station. |
