Display method and device for MVA (multi-domain vertical alignment) wide viewing angle LCD (liquid crystal display) screen

Abstract

The invention provides a display method and a display device for an MVA (multi-domain vertical alignment) wide viewing angle LCD (liquid crystal display) screen. According to the display method for the MVA wide viewing angle LCD screen, a gray scale value difference between two pixel points in two continuous images to be displayed and located at the same position is increased, and then a gray scale voltage difference obtained by the two pixel points of the two continuous images to be displayed, located at the same position, in display is increased. Due to the fact that liquid crystal deflection directions of liquid crystal molecules under different gray scale voltage functions are different, a deflection difference between the deflection directions of the liquid crystal molecules in a pixel point structure of the LCD screen when the LCD screen respectively displays a first video frame and a second video frame is increased, and after a human eye observes the first video frame and the second video frame, the human eye can observe the images displayed at different observation view angles after the first video frame and the second video frame are displayed, and simultaneously a viewing angle of the LCD screen is enlarged on the premise that the quantity of domains in the pixel point structure of the LCD screen is not increased.

Description

technical field [0001] The invention relates to the technical field of image display, in particular to a display method and device applied to an MVA wide viewing angle liquid crystal screen. Background technique [0002] In the field of liquid crystal display screens, the display resolution of liquid crystal display screens continues to increase, and consumers' demand for liquid crystal display screens shifts from higher display resolution to wider display angles. At present, the mainstream high-resolution liquid crystal display mainly adopts MVA (Multi-domain Vertical Alignment, multi-domain vertical alignment) technology to expand the viewing angle of the liquid crystal display. Such as figure 1 As shown, the MVA technology divides a pixel point into multiple regions, and the liquid crystal molecules in each region deflect in different directions after voltage is applied, thereby expanding the overall viewing angle of a pixel point. figure 1 Among them, 21 is the color f...
