First Claim
Patent Images

1. display device, it comprises:

  • Pixel portion, it has a plurality of image element circuits of two-dimensional arrangement, and each image element circuit is as comprising that the circuit of switching device, display element and holding capacitor is arranged on the intersection point place of sweep trace and signal wire;

    WithCorrecting circuit, it is configured to proofread and correct the storage capacitor voltage that offers described holding capacitor,Wherein said correcting circuit adopts;

    Comparer, it is configured to detect each current potential of receiving from the part of described pixel portion, as having the pixel current potential of positive polarity and have difference between the pixel current potential of negative polarity, and be configured to the described difference of comparison current potential and reference voltage andOutput voltage controlling circuit, it is configured to convert the comparative result of described comparer output to be used to proofread and correct described storage capacitor voltage correction signal, and described correction signal will be applied in the storage capacitor line that is used to provide described storage capacitor voltage.
