Abstract
A pixel circuit compensation method is provided, including: acquiring a threshold voltage of a driving transistor in each subpixel of a display panel; determining whether there is an abnormal voltage in the threshold voltages; and when there is the abnormal voltage, adjusting a compensation signal to be applied to a first subpixel corresponding to the abnormal voltage.
Claims17
A pixel circuit compensation method, comprising:
- acquiring a threshold voltage of a driving transistor in each subpixel of a display panel;
- determining whether there is an abnormal voltage in the threshold voltages;
- and
- in response to determining the abnormal voltage, adjusting a compensation signal to be applied to a first subpixel corresponding to the abnormal voltage,
- wherein determining whether there is the abnormal voltage comprises:
- determining whether the threshold voltages applied to all subpixels in a same row or a same column are the same;
- and
- when the threshold voltages applied to all the subpixels in the same row or same column are the same, determining the threshold voltages applied to all the subpixels in the same row or same column as the abnormal voltages.
