Display device driving method and display device

Abstract

The invention discloses a display device driving method and a display device. The driving method comprises steps that a pre-display image is acquired; n sets of target gray scale value pairs of a pixel set are acquired through table query according to an average value of preset gray scale values corresponding to two blue sub pixels of the pixel set; one pre-display image is displayed in m continuous frame display periods; each pixel set comprises two pixels; the gray scale values of the two blue sub pixels of one same frame display period pixel set are respectively a first target gray scale value greater than the preset gray scale value and a second target gray scale value smaller than the preset gray scale value in one target gray scale value pair set; the target gray scale values corresponding to the pixel set on the same position of the display panel in at least two frame display periods are different. The driving method is advantaged in that a color cast problem of the liquid crystal display panel under the large vision angle condition is further ameliorated.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a method for driving a display device and a display device. Background technique [0002] Traditional large-size liquid crystal display devices mostly use negative VA (Vertical Alignment, Vertical Alignment) liquid crystal or IPS (In-Plane Switching, in-plane switching) liquid crystal technology. When the VA-type liquid crystal display device has a large viewing angle, the brightness of the pixels in it saturates rapidly with the driving voltage, which leads to serious color shift phenomenon under the large viewing angle of the liquid crystal display device, which in turn affects the display quality of the liquid crystal display device. [0003] When the original driving signal for driving the sub-pixels in the liquid crystal display panel is divided into a high-voltage signal and a low-voltage signal to drive the sub-pixels in the liquid crystal dis...

AI Technical Summary

Problems solved by technology

However, providing different driving voltages to the main pixel and sub-pixels in each sub-pixel needs to cooperate with some metal wiring and thin-film transistor elements to drive the main and sub-pixels for display, and these metal wiring and thin-film transistor elements will affect the liquid crystal display panel. Light emitting, so that the light-permeable opening area of ​​the liquid crystal display panel is greatly reduced, affecting the transmittance of the liquid crystal display panel, resulting in an increase in the cost of the backlight of the liquid crystal display panel
