Problems solved by technology

[0004] However, since the connection wire has resistance, the longer the connection wire, the greater the resistance. Therefore, different lengths of the connection wire have different effects on the voltage input from the driver to the data line, which will affect the brightness uniformity of the display panel and affect the brightness of the display panel. display effect

Abstract

The application discloses a display panel driving method, device, computer equipment and storage medium, belonging to the field of display technology. In the method, before displaying the target image, the first voltage corresponding to the target data line is determined first, and the first voltage is greater than the target voltage of the Pth sub-pixel connected to the target data line. At the beginning of the P-th scanning period for displaying the target image, the first voltage is input to the connection line corresponding to the target data line. When the luminous brightness of the Pth subpixel connected to the target data line reaches the target brightness, the target voltage of the Pth subpixel is input to the connection line corresponding to the target data line. The display panel driving method can eliminate the influence of the connection line corresponding to the target data line on the luminous brightness of the sub-pixels connected to the target data line, thereby improving the brightness uniformity of the display panel and improving the display effect of the display panel.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display panel driving method, device, computer equipment and storage medium. Background technique [0002] The display panel includes a plurality of scanning lines, a plurality of data lines, a plurality of sub-pixels, and a plurality of switch circuits corresponding to the plurality of sub-pixels. When the display panel is working, the scan line outputs a scan signal to control the switch circuit to be turned on. The data line writes a target voltage into the corresponding sub-pixel through the switch circuit, charges the sub-pixel, and makes the corresponding sub-pixel emit light with a target brightness. [0003] In the related art, each data line needs to be connected to a driver on a COF (Chip On Film, chip-on-film) through a connection line. Due to the location of the drives, the length of each connecting cable is different. [0004] However, due to the ...
