Title:
DISPLAY PANEL, DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/012236
Kind Code:
A1
Abstract:
A display panel, a driving method therefor, and a display device. The driving method comprises: determining a brightness segment in which a display panel is found, brightness segments comprising first to Nᵗʰ brightness segments, the maximum grayscale brightness sequentially decreasing from the first to the Nᵗʰ brightness segment, and each brightness segment from the (N – M)ᵗʰ brightness segment to the Nᵗʰ brightness segment respectively corresponding to at least one duty cycle; determining, on the basis of a gamma correction curve corresponding to the brightness segment determined and of an image to be displayed, an input data voltage corresponding to at least one light-emitting unit (200); and driving, on the basis of the input data voltage determined, or, on the basis of the input data voltage determined and of the duty cycle, the display panel to display said image, when driving the display of each frame of image from the (N – M)ᵗʰ brightness segment to the Nᵗʰ brightness segment, the current flowing through each light-emitting component being greater than a preset reference current of each light-emitting component, and the duration of connection being less than a preset reference duration of connection (300). The driving method improves the problem of motion blur and color cast and enhances display effects.
