Abstract
This application relates to a display panel and a pre-charge switching method for pixel units thereof. A timing controller of the display panel stores a gray-scale threshold. The timing controller calculates a gray-scale eigenvalue by using a first gray-scale parameter corresponding to pixel units in a first row and a second gray-scale parameter corresponding to pixel units in a second row, and pulls up a potential of a pre-charge signal when determining that the gray-scale eigenvalue satisfies a condition of the gray-scale threshold. A gate drive unit provides a scanning signal to a gate line in a second row within a period of providing a scanning signal to a gate line in a first row when the pre-charge signal is at a high potential.
