【Abstract】 A design project of STN LCD driver and controller with 4-gray scale is presented in this paper. The key modules including interface circuit, SRAM module, display control circuit and power supply circuit are discussed in detail. In the conditions of implementing many display functions, we adopt power save mode, gating clock and retiming method to reduce power consumption. SMIC 0.35um CMOS High Voltage model is used to verify the function of this driver and controller.更多还原
