Compensation method of dark spot sub-pixel in display panel and display panel

The application discloses a compensation method for a dark point sub-pixel of a display panel and the display panel. The method comprises the following steps: generating a brightness compensation value according to the brightness value of a dark point sub-pixel group at a preset gray scale and the brightness value of a normal sub-pixel group at the preset gray scale; and compensating at least one normal sub-pixel in the dark point sub-pixel group according to the brightness compensation value. After determining that there is a dark point sub-pixel in the display panel, the brightness compensation value is generated according to the deviation between the brightness value of a dark point sub-pixel group to which the dark point sub-pixel belongs at a preset gray scale and the brightness value of a normal sub-pixel group at the preset gray scale, and the brightness of the normal sub-pixels near the dark point sub-pixel is compensated according to the brightness compensation value, so that the brightness of the normal sub-pixels near the dark point sub-pixel is improved, and then the brightness value of the dark point sub-pixel group at the preset gray scale after compensation is equal to the brightness value of the normal sub-pixel group at the preset gray scale, and the display unevenness caused by the dark point sub-pixel is improved.

Display device

ActiveCN120833735BRealize chargingMinimize charging variance
This invention provides a display device in which two cascaded gate driving circuits are spaced X gate driving circuits apart. The phase difference of the first clock signals corresponding to the two cascaded gate driving circuits is (X+1)H. In at least one sub-pixel, the effective level of the first gate control signal corresponding to the compensation transistor and the effective level of the second gate control signal corresponding to the data transistor at least partially overlap. The effective level of the second gate control signal corresponding to the data transistor is located between the two first effective levels of the first clock signal applied by the gate driving circuit corresponding to the compensation transistor, and the phase difference between the effective level of the second gate control signal corresponding to the data transistor and one of the two first effective levels is greater than 0 and less than (X+1)H. This ensures that in the same sub-pixel, the effective level of the second gate control signal corresponding to the data transistor does not coincide with the moment when the voltage drop of the first gate control signal corresponding to the compensation transistor occurs, thereby improving the problem of uneven display.
