Gamma calculation method and device and display panel

Abstract

An embodiment of the invention discloses a gamma calculation method, a gamma calculation device, and a display panel. The gamma calculation method comprises the steps of: determining a corresponding register gain value of second binding point brightness on a straight line connecting line according to the straight line connecting line of two endpoints, in a first binding point brightness interval to which a reference curve belongs, corresponding to the second binding point brightness under a to-be-calculated display brightness level in a data voltage dimming interval; determining a target register offset value corresponding to the second binding point brightness according to a preset corresponding relationship between a target register offset value corresponding to the second binding pointbrightness and a preset midpoint offset value corresponding to the middle brightness of the two endpoints; and determining a gamma register value corresponding to the second binding point brightness under the to-be-calculated display brightness level according to the register gain value and the target register offset value. According to the gamma calculation method and the gamma calculation device, the gamma register value under any preset display brightness level in the data voltage dimming interval can be determined through calculation according to the group of gamma register values under the maximum display brightness level in a data voltage dimming interval, so that the gamma debugging time can be shortened.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a gamma calculation method, device and display panel. Background technique [0002] With the development of display technology, the image quality requirements of display products are also getting higher and higher. [0003] In the prior art, the image quality of the display panel is usually improved by increasing the number of gamma debugging groups, but the above-mentioned existing solution has the problem that the gamma debugging of the production line takes a long time, which affects the production capacity of the production line. Contents of the invention [0004] The present invention provides a gamma calculation method, a device and a display panel, so as to reduce the number of gamma debugging groups, shorten the gamma debugging time of the display panel, and improve production line productivity. [0005] In the first aspect, an embodimen...
