Display panel gamma adjustment method and device

Abstract

The invention discloses a display panel gamma adjustment method and a display panel gamma adjustment device. The display panel gamma adjustment method is characterized by acquiring target brightness corresponding to a plurality of preset gray scales under a preset display brightness level instruction; determining a target gray scale corresponding to the target brightness under a second display brightness level instruction according to a preset corresponding relationship between the target brightness and the target gray scale; and determining a target data voltage corresponding to the target brightness under the preset display brightness level instruction according to a binding point gray scale interval to which the target gray scale belongs under the second display brightness level instruction. A group of gamma voltages under any preset display brightness level instruction in a data voltage dimming interval can be calculated according to a group of gamma voltages under a maximum display brightness level instruction in the data voltage dimming interval; only gamma debugging needs to be carried out under the maximum display brightness level instruction to obtain a group of gamma voltages under the maximum display brightness level instruction in one data voltage dimming interval, so that the time of gamma debugging and gamma voltage burning can be shortened, and the productivity of a production line is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a method and device for adjusting gamma of a display panel. Background technique [0002] With the development of display technology, the demand for screen quality display in the current terminal market continues to increase.
