LIQUID CRYSTAL DISPLAY PIXEL WITH INCREASED VOLTAGE MODULATION CAPABILITY

摘要

A liquid crystal display pixel is presented that maintains voltage modulation capability across a liquid crystal display pixel while keeping sustainable voltages across the junctions of the gate transistor for fine semiconductor fabrication processes. In one embodiment of the present invention, a liquid crystal display pixel includes a first gate transistor and a second gate transistor coupled in series from a substrate of the liquid crystal display pixel to a driving voltage line. The configuration prevents unsustainable voltages from appearing across the junctions of any single gate transistor while maintaining voltage modulation across a liquid crystal. In a second embodiment of the present invention, a liquid crystal display pixel with frame store capability includes a further clamping transistor to prevent high transient voltage from appearing across the junctions of any single gate transistor. The configuration prevents unsustainable voltages from appearing across the junctions of any single gate transistor while maintaining voltage modulation across a liquid crystal.
