Development of a resistivity division driving method for the vertically placed RGB pixels of the eight-domain thin-film-transistors liquid crystal display

摘要

A new multi-domain driving technology for a vertically placed RGB pixel structure with subpixels (MB7) was developed. Subpixel A (high-tilt-angle domain) was charged with the data voltage, without any change. The two directly connected thin-film-transistors (TFTs) functioning as a parallel-resistors circuit could reduce the data voltage supplied to subpixel B (low-tilt-angle domain). The amount of voltage drop for subpixel B could be easily controlled by adjusting the TFT channel width ratio between the parallel resistors. Through the use of this new method, a 32-in. HD TFT liquid crystal display (TFT-LCD) TV panel with a wide viewing angle was successfully fabricated.
