Patent ID: 7573459

Claim:
A pixel structure for an liquid crystal display (LCD) with an embedded touch screen, comprising: a plurality of first pixels and a plurality of second pixels, each formed by intersecting two adjacent gate lines and two adjacent data lines, said first pixel comprising: a pixel transistor having a gate electrode connected to one of said gate lines, a drain electrode connected to one of said data lines, and a source electrode; a pixel electrode connected to said source electrode of said pixel transistor; a liquid crystal capacitor C LC formed between said pixel electrode and a common electrode; a compensation capacitor C C formed between said pixel electrode and a compensation electrode; and said second pixel comprising: a pixel transistor having a gate electrode connected to one of said gate lines, a drain electrode connected to one of said data lines, and a source electrode; a pixel electrode connected to said source electrode of said pixel transistor; a liquid crystal capacitor C LC ″ formed between said pixel electrode and a common electrode; a readout capacitor C read-out between said pixel electrode and a readout line, wherein said pixel electrode is positioned above said readout line, and said pixel electrode and said readout line are overlapped.
