Problems solved by technology

[0005] However, the existing debugging methods can only ensure good display quality of individual patterns, but they are not universally applicable, especially for large-sized display devices, such as TV products, because the image display effect will be nonlinear due to the brightness of the display device The impact has a relatively large difference, resulting in the phenomenon of image sticking (Image Sticking), which cannot meet the expected picture display quality requirements

Abstract

The invention provides an image display quality modulating method and an image display quality modulating device for a display device. The method comprises the steps of debugging the display device to be in a modulating state, so as to enable the common voltage of the gray scale 127 of the display to be a standard voltage; and modulating the common voltages of other controllable gray scales of the display device to be a preset value, wherein a first preset relation is arranged between the preset valve and the standard voltage. Therefore, the common voltages of the gray scales in the display device are maintained in a same horizontal line, so that the image residual phenomenon can be maximally reduced, and the screen display quality requirement of the display device can be guaranteed.

Description

technical field [0001] The present invention relates to the field of display technology, and specifically relates to a method and device for modulating the display quality of a display device. Background technique [0002] When the display device is displaying, there is a nonlinear relationship between the input voltage applied to the pixel and the pixel brightness / transmittance, and the curve that reflects this nonlinear relationship is called the gamma curve (Gamma curve) ). [0003] Existing display devices need to perform voltage conversion based on a preset Gamma characteristic curve during use, and the gap between the gamma value of the actual Gamma characteristic curve of the display device and the target gamma value (generally 2.2) determines the The final display effect (the smaller the gap, the better the display effect). [0004] Therefore, before the display device leaves the factory, it is necessary to perform certain adjustments on the display device to obtai...
