Abstract: A method of controlling a display panel, a display panel, and a display device are disclosed. The display panel includes a display panel for image displays. The method of controlling the display panel includes obtaining a target grayscale area in the display area, and driving grayscales of the target grayscale area based on a desired voltage. The desired voltage is obtained by at least two times of adjustments according to historical display data of the target grayscale area. The present application is provided to improve display effects of the display panel.

Abstract: The present disclosure provides a setting method of a display panel and the display panel, the method includes: acquiring a first chromaticity information of a first gray scale and a second chromaticity information of a second gray scale; acquiring a first difference value between the first chromaticity information and the second chromaticity information; and adjusting gray scale voltages of the first gray scale and/or the second gray scale when the first difference value is greater than a preset difference threshold, and a second difference value between the first chromaticity information and the second chromaticity information after adjustment is less than the first difference value.

Abstract: The present application provides a grayscale calibrating method for a display panel and a display device. The grayscale calibrating method for a display panel includes obtaining a screen image to be displayed of the display panel, and determining whether the screen image to be displayed exists in an abnormal display region; when the screen image to be displayed exits in the abnormal display region, increasing the grayscale of each of the first sub-pixels located in the first display region by changing a white balance component to improve the display effect of the abnormal display region.

Abstract: A display system includes a display panel and a pair of glasses. The display panel includes a display panel body, a first polarizer disposed on a non-display side of the display panel body, and a first wave plate disposed on a display side of the display panel body. The display side is opposite to the non-display side. The pair of glasses includes a second polarizer and a second wave plate. The second polarizer includes a polarizing layer. The second wave plate is disposed on a side of the polarizing layer away from eyes. The pair of glasses is configured to present images displayed by the display panel.
