  • Patent number: 11081051
    Abstract: Provided is a pixel compensation circuit, which includes a signal amplification circuit, a signal storage circuit, a comparison calculation circuit and a signal compensation circuit. The signal amplification circuit collects an anode potential of an organic light emitting element and a driving current, such that the signal storage circuit can determine a threshold voltage of the driving transistor and a preset gray-scale voltage based on the anode potential and the driving current. The comparison calculation circuit calculates a compensation voltage required for the pixel while actually operating based on the threshold voltage, the anode potential and the preset gray-scale voltage. Thus, when a display gray-scale voltage is inputted, it can be compensated using the compensation voltage and then outputted to a gate of the driving transistor, such that the driving transistor can drive the organic light emitting element to emit light.
