| Abstract: | In this paper, a software model based on PC is developed for the hardware-driving and grey shading technology of Color Super Twisted Nematic-Liquid Crystal Display (CSTN-LCD). The influence of different combinations of Multiple Line Addressing (MLA) arithmetic and grey shading technology are considered. By applying Frame Rate Control (FRC) and Pulse Height Modulation (PHM), the FRC-MLA-PWM scheme for driving CSTN-LCD is validated for high cost-performance ASIC design. It is believed that this scheme will offer a useful reference for Register Transfer Level (RTL) circuit design. |
