Abstract:
1. A method for driving a transflective LCD, wherein the transflective LCD has a plurality of pixels arranged in a matrix, each including a reflective cell and a transmission cell, the reflective cell having a first storage capacitor and a first active device, and the transmission cell having a second storage capacitor and a second active device, the method comprising the steps of: providing first switching devices coupled between the reflective cells of the pixels and first driving voltages respectively; providing second switching devices coupled between the transmission cells of the pixels and second driving voltages respectively; turning on all the first switching devices and scanning the reflective cells in turn to apply the first driving voltages to the reflective cells in turn; and turning on all the second switching devices and scanning the transmission cells in turn to apply the second driving voltages to the transmission cells in turn; wherein the first driving voltages are applied to the reflective cells in turn and the second driving voltages are applied to the transmission cells in turn in one frame period.
