摘要： In an LCD pixel, the pixel voltage is usually reduced after a gate line signal has passed. To compensate for this voltage reduction, the voltage applied to the charge storage capacitor in the pixel is increased from Vcom to Vcom1 after the gate line signal has passed. Voltage adjustment can be achieved by using two switching elements connected to the second end of the charge storage capacitor. One is activated by the gate line signal so that the applied voltage is equal to Vcom, and the other is activated by the next gate line signal so that the applied is increased to Vcom1. In a transflective LCD panel or a color LCD panel, each pixel is divided into two or three sub-pixels, each sub-pixel having a separate charge storage capacitor, a similar Vcom change is applied to each of the charge storage capacitors in the pixel.

The gate lines are for deciding whether to enable the pixel units. Each of the touch control units is electrically coupled to the readout line and a corresponding one of the gate lines and includes a switching element. When one of the touch control units is touched, the switching element of the touched touch control unit is turned on, and thereby a waveform on the gate line corresponding to the touched touch control unit is coupled to the readout line and a position of the touched touch control unit is determined according to a timing sequence of a waveform on the readout line. The present invention also provides a touch detection method adapted to be implemented on the above-mentioned display apparatus.
