Method for driving transflective liquid crystal display

A method for driving a transflective LCD, wherein the transflective LCD has a plurality of pixels arranged in a matrix, each pixel 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;
• scanning each row of the pixels in turn in one frame period;
• and
• turning on the first switching device and the second device at different times to apply the first driving voltage to the reflective cells and the second driving voltage to the transmission cells respectively, when each pixel row is scanned.
