  • Patent number: 9570034
    Abstract: The present disclosure relates to a pixel cell circuit of compensation feedback voltage. The pixel cell circuit is provided with the compensation capacitance (C_co), one end of the compensation capacitance (C_co) electrically connects to the compensation level wirings G(m)_co, and the other end of the compensation capacitance (C_co) electrically connects to the drain of the TFT (T1) and the pixel electrode (P). A level of the compensation signals transmitted by the compensation level wirings G(m)_co is opposite to the level of the scanning signals transmitted by the scanning lines G(m). When the pixel electrode has been fully charged, the compensation capacitance generates a pull-up feedback voltage for compensating the pull-down voltage caused by the parasitic capacitance so as to eliminate the effects toward the pixel electrodes caused by the scanning signals transmitted by the scanning lines. This configuration not only decreases the flickers, but also the image sticking.

    Abstract: An array substrate includes a gate line, a data line and a plurality of pixel units defined by the gate line and the data line intersecting with each other, which are formed on a base substrate, and each pixel unit includes a thin film transistor. The farther the thin film transistor is away from a gate driver side of the array substrate, the more likely an overlapping area between an active layer and a source electrode of the thin film transistor shows an increasing trend. By changing the overlapping area between the active layer and the source electrode, a dielectric constant between a gate electrode and the source electrode increases to enlarge a gate-source capacitance Cgs, leading to an increase of ?Vp; as a result, a common electrode voltage tends to be stable, thus avoiding crosstalk at the time of displaying.
