Abstract
A method for driving a display panel and a display apparatus are provided. The display panel includes a display region including a fingerprint recognition region and includes subpixels located in the display region, and the subpixels include first subpixels located in the fingerprint recognition region and used as a light source for fingerprint recognition. In a first mode, the subpixels are scanned at a first frequency, and in the second mode, the subpixels are scanned at a second frequency. The second frequency is greater than the first frequency. The method includes: when the display panel is in the first mode, monitoring whether the display panel receives a fingerprint recognition requirement, and if yes, controlling the display panel to enter a trigger state; and when the display panel is in the trigger state, scanning the first subpixels at a frequency greater than the first frequency.
