Display method and device applied to MVA (Multi-domain Vertical Alignment) wide-view-angle liquid crystal screen

Abstract

The invention relates to the technical field of image display and provides a display method and device applied to an MVA (Multi-domain Vertical Alignment) wide-view-angle liquid crystal screen. The method provided by the embodiment of the invention comprises the following steps: after receiving a video frame to be displayed, determining first gray scale voltage and second gray scale voltage of each pixel point in the video frame to be displayed; and displaying the video frame to be displayed as a first image and a second image according to the first gray scale voltage of each pixel point and the second gray scale voltage of each pixel point in the video frame to be displayed respectively. The average value of light transmittances corresponding to the first gray scale voltage and the second gray scale voltage of each pixel point is not less than a pre-set light transmittance of the pixel point; meanwhile, the director of liquid crystal is different when the video frame to be displayed is displayed each time. Therefore, a wider liquid crystal screen view angle can be obtained by the method. under the condition that the light transmittance is not changed when the liquid crystal screen displays the images.

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. like 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 filt...
