Problems solved by technology

[0004] When the existing anti-peep display is displayed at a narrow viewing angle, the anti-peep display not only has a horizontal electric field that drives the liquid crystal molecules to rotate in the horizontal plane, but also has a vertical electric field, so that part of the liquid crystal molecules are tilted, from the upper right side and the right side of the anti-peep display. There will be a gray scale difference in the picture viewed from the lower side, but there will be no gray scale difference in the picture viewed from the upper left side and the lower left side of the anti-peeping display, which will cause the problem of gray scale inversion when the anti-peeping display is displayed at a narrow viewing angle

Abstract

Provided is a method for displaying a display panel in a narrow view angle. The display panel includes a plurality of pixels arranged in a matrix, each pixel includes a first sub-pixel arranged in a matrix, second sub-pixel, the third sub-pixel and the fourth sub-pixel, A method comprise that steps of: when a display panel is display at a narrow viewing angle, A first voltage is applied to the first sub-pixel and the fourth sub-pixel, and a second voltage is applied to the second sub-pixel and the third sub-pixel, the voltage magnitude of the first voltage is different from the voltage magnitude of the second voltage, and the liquid crystal twist angle in the first sub-pixel and the fourth sub-pixel is different from the liquid crystal twist angle in the second sub-pixel and the third sub-pixel. The liquid crystal twist angle in the first sub-pixel and the fourth sub-pixel is different from that in the second sub-pixel and the third sub-pixel. The narrow viewing angle display method ofthe invention can effectively improve the gray scale inversion because the torsion angle of the liquid crystal in each sub-pixel is different.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a narrow viewing angle display method. Background technique [0002] Liquid crystal display (liquid crystal display, LCD) has the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and occupies a dominant position in the field of flat panel display. [0003] With the continuous advancement of liquid crystal display technology, the viewing angle of the display has been expanded from about 120° to more than 160°. While enjoying the visual experience brought by the large viewing angle, people also hope to effectively protect commercial secrets and personal privacy. Avoid commercial loss or embarrassment caused by information leakage on the screen. Therefore, in addition to the requirement for a wide viewing angle, it is also required in many occasions that the dis...
