Embodiment Construction

[0054] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0055] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain that it is in a specific posture (as shown in the drawings). If the specific posture changes, the relative positional relationship, movement, etc. of the components below will also change the directional indication accordingly.

Abstract

The invention discloses a display device, and a driving method and a driving assembly thereof; the display device driving method comprises the following steps: obtaining an original gray scale of thepixel; obtaining a correction factor of the pixel according to the original gray scale; obtaining a first gamma level of the pixel according to the first gamma value and the original gray scale; obtaining a second gamma level of the pixel according to the second gamma value and the original gray scale; obtaining a first data level of the pixel according to the correction factor, the first gamma level and the second gamma level, and applying the first data level on the main pixel; obtaining a third gamma level of the pixel according to the third gamma value and the original gray scale; obtaining a second data level of the pixel according to the correction factor, the first gamma level and the third gamma level, and applying the second data level on the secondary pixel. The method and devicecan improve the display effect of the display device.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display device, a driving method thereof, and a driving assembly. Background technique [0002] In the display device, especially the liquid crystal display device, due to the limitation of the deflection of the liquid crystal, the transmittance-driving voltage curve of the display device will drift relative to the transmittance-driving voltage curve in the case of a positive viewing angle in the case of a bias viewing angle. , Resulting in a reduction in the contrast of the screen, resulting in color shift, reduced resolution, and reduced chromaticity and viewing angle. In order to correct the phenomenon that the resolution decreases and the chromaticity viewing angle becomes smaller under the biased viewing angle, the pixel or sub-pixel can be divided into two parts A and B, and the A part and the B part can be controlled to display different brightness. However, this me...
