    摘要: A common-voltage compensation circuit functions to provide a crosstalk interference suppressing mechanism for use in a liquid crystal display having a liquid-crystal capacitor and a storage capacitor. The compensation circuit includes a buffer for receiving a preliminary common voltage, a current/voltage converter, a high-pass filter and a ripple-voltage inverter. The current/voltage converter is utilized for generating a liquid-crystal capacitor common voltage furnished to the liquid-crystal capacitor according to an output current of the buffer. The high-pass filter performs a high-pass filtering operation on the liquid-crystal capacitor common voltage for extracting a ripple voltage. The ripple-voltage inverter is employed to generate a storage capacitor common voltage furnished to the storage capacitor through performing an inverting operation on the ripple voltage based on the preliminary common voltage. The ripple voltage of the storage capacitor common voltage has a phase opposite to that of the liquid-crystal capacitor common voltage for suppressing crosstalk interference.

    摘要: A pixel circuit includes a first sub-pixel and a second sub-pixel. The first sub-pixel is coupled to a scan line and a data line, so as to determine whether to be enabled according to a first scan signal transmitted on the scan line, and whether to be driven according to a data signal transmitted on the data line. The second sub-pixel is coupled to the scan line, so as to determine whether to be enabled according to the first scan signal. The data signal is in a first state when the first scan signal is in a pre-charged period. The data signal is in a second state during a time interval after the pre-charged period is over and before the first scan signal enters a turn-on period. Voltage polarities of the first state and the second state are opposite. The pixel design can improve color shift and frame flicker.
