Liquid crystal display

Abstract

The present invention provides a liquid crystal display, comprising: a plurality of pixels arranged in a matrix, each pixel including a first sub-pixel and a second sub-pixel; a plurality of first gate lines connected to the first sub-pixel; a plurality of first sub-pixels Two gate lines, connected to the second sub-pixel; and a plurality of data lines, crossing the first and second gate lines, connected to the first and second sub-pixels, and transmitting data voltages, wherein the first and second sub-pixels of each pixel The voltages of the two sub-pixels have opposite polarities and are obtained from a single image information, and the data voltage carried by the data line is inverted by N×1 (N=1, 2, . . . ), N:M×1( M=1, 2, ...) point inversion, or N row inversion.

Description

technical field [0001] The invention relates to a liquid crystal display. Background technique [0002] Liquid crystal displays (LCDs) are among the most widely used flat panel displays. The LCD includes a pair of panels including field generating electrodes such as pixel electrodes and common electrodes, and a liquid crystal (LC) layer interposed between the panels. The LCD generates an electric field in the LC layer by applying a data voltage to a pixel electrode and a common voltage to a common electrode. The desired image is obtained by controlling the strength of the electric field which determines the orientation of the LC molecules and the polarization and transmittance of the incident light. [0003] In a vertical alignment (VA) mode LCD, long axes of LC molecules are aligned perpendicular to the panel in the absence of an electric field. The importance of this type of LCD lies in its high contrast ratio and wide reference viewing angle, ie the viewing angle at wh...
