Abstract: A driving chip, a control method therefor and a display device are provided. The driving chip includes Gamma voltage generating circuits, first power supply voltage output circuits and a color cast adjustment circuit. The Gamma voltage generating circuits correspond to sub-pixels of different colors. The first power supply voltage output circuits are electrically connected to different Gamma voltage generating circuits and each of the first power supply voltage output circuits is configured to output a first power supply voltage to a corresponding first power supply voltage terminal. The color cast adjustment circuit is electrically connected to each first power supply voltage output circuit, and is configured to adjust the first power supply voltage output by at least one first power supply voltage output circuits according to a light-emitting duration of a light-emitting device in a display panel per unit time.

Abstract: A display method of a display panel is described. The display panel has a first display area and a second display area, first sub-pixels are located in the first display area and second sub-pixels are located in the second display area, and a sub-pixel density of the second display area is smaller than that of the first display area. The display method includes: in displaying one frame of image, performing display in the first display area and the second display area by using different display algorithms. A sub-pixel rendering is used to perform display in at least one of the first display area and the second display area. A number of data signals provided to the first display area and a number of the first sub-pixels are identical. A number of data signals provided to the second display area and a number of the second sub-pixels are identical
