Abstract

The present application provides a foldable display panel, a display device, an image compensation method and a device thereof. The foldable display panel includes a first display panel and a second display panel that can be folded in half along the adjacent edges, and the two display panels The sub-pixels in all are sub-pixels with optical information detection function. When the first display panel and the second display panel are in the folded and closed state, the sub-pixels on one display panel are used to detect the sub-pixels on the opposite display panel. The optical information of the pixel, so as to obtain the optical information of each sub-pixel, and then perform optical compensation for each sub-pixel. Since the optical information detection and image compensation are performed in the folded and closed state, it does not affect the use of the display panel user; in addition, the optical image compensation can be continuously performed multiple times during the use of the display panel after leaving the factory, and the optical image compensation is real-time. Therefore, the display image quality of the foldable display panel can be guaranteed.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a foldable display panel, a display device, an image compensation method and a device thereof. Background technique [0002] An organic light-emitting display device uses an organic light-emitting diode (OLED, Organic Light-Emitting Diode) to display images. Flexible OLEDs make possible flexible display devices such as rollable display panels and foldable display panels. However, in the process of use, parameters such as the threshold voltage and mobility of the driving thin film transistor (TFT) in the OLED display panel have non-uniformity, resulting in differences in the current and brightness of different OLED display devices, resulting in spotting; and the TFT threshold voltage The drift of the OLED and the degradation of the OLED will also cause differences in the brightness of the pixels related to the displayed picture on the OLED display panel, forming a displa...
