Claim:
1. A pixel cell circuit of the compensation feedback voltage, comprising: a TFT, a gate of the TFT electrically connecting to a scanning line corresponding to a row of the pixel cell, a source of the TFT electrically connecting to a data line corresponding to a column of the pixel cell, and a drain of the TFT electrically connecting to a pixel electrode; the pixel electrode electrically connecting to the drain of the TFT; a parasitic capacitance, one end of the parasitic capacitance electrically connecting to the gate of the TFT, and the other end of the parasitic capacitance electrically connecting to the drain of the TFT and the pixel electrode; a compensation capacitance, one end of the compensation capacitance electrically connecting to the compensation level wirings, and the other end of the compensation capacitance electrically connecting to the drain of the TFT and the pixel electrode; and compensation level wirings, a level of the compensation signals transmitted by the compensation level wirings being opposite to the level of the scanning signals transmitted by the scanning lines; and wherein C_co×V_co=(Vgh−Vgl)×Cgs; wherein C_co represents a compensation capacitance, V_co represents a voltage difference between the high and low level of the compensation signals transmitted by the compensation level wirings, Vgh represents the high level of the scanning signals transmitted by the signal line, Vgl represents the low level of the scanning signals transmitted by the signal lines, and Cgs represents parasitic capacitance.
