Abstract

The invention belongs to the technical field of display and mainly provides a display panel driving method and driving device. The method comprises the steps of dividing the display panel into n sub-regions, and calculating an average gray scale value of an original pixel cell in each sub-region, where n is an integer greater than 1; when the average gray scale value is great than the preset grayscale threshold, determining a gray level threshold interval corresponding to the sub-region according to the average gray level value of the sub-region, calculating a ratio of a total amount of original pixel units in a gray-scale threshold interval to a total amount of original pixel units contained in a corresponding sub-region, and according to the ratio and the preset gamma value conversion relation, resetting the gamma value of the original pixel unit in the corresponding sub-region, thus achieving the purpose of reducing the color deviation of the display panel. The problem that the brightness of the existing VA-type liquid crystal panel technology in the large viewing angle rapidly saturates with the increase of the driving voltage, thus deteriorating the picture quality of the large viewing angle and greatly affecting the experience of the user is solved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a driving method, a driving device and a display device of a display panel. Background technique [0002] Existing large-size liquid crystal display panels usually use Vertical Alignment (Vertical Alignment, VA) type liquid crystal panels or in-plane switching (In-Plane Switching, IPS) type liquid crystal panels. Compared with IPS type liquid crystal panel technology, VA type liquid crystal panel technology has The advantages of higher production efficiency and lower manufacturing costs. [0003] However, the brightness of the existing VA-type liquid crystal panel technology saturates rapidly with the increase of the driving voltage at large viewing angles, which deteriorates the quality of the image quality at large viewing angles and greatly affects the user experience. Contents of the invention [0004] The present invention provides a driving method, a driving...
