Low Power Consumption Transflective Liquid Crystal Displays

摘要

Techniques are provided to drive a normally white or mixed mode LCD with low voltages and low power consumption. A sub-pixel in the LCD may comprise a reflective part and a transmissive part. The cell gap for a liquid crystal layer in the sub-pixel may provide at least a half-wave phase retardation. A driving voltage range with a maximum voltage at a low value may be used to drive the reflective part and the transmissive part of the sub-pixel to various levels of brightness.
