Abstract
The present disclosure provides a method and a device for modulating image display quality of a display device. The method includes: debugging a display device to a modulation state, so that a common voltage of the display device corresponding to a predetermined gray level is a standard voltage; and modulating a common voltage of the display device corresponding to other controllable gray level into a preset value, wherein there is a first preset relationship between the preset value and the standard voltage.
