Embodiment Construction

[0028] Please refer to image 3 , image 3It is a schematic diagram of a liquid crystal display 300 adopting a zigzag layout and a single-gate structure in the present invention. The liquid crystal display 300 includes a gate driving circuit 310 , a source driving circuit 320 , a switch control circuit 340 , and a liquid crystal display panel 330 . The liquid crystal display panel 330 is provided with a plurality of data lines DL1 -DLM parallel to each other, a plurality of gate lines GL1 -GLN parallel to each other, and a pixel matrix including M columns and N rows. The data lines DL1-DLM and the gate lines GL1-GLN are arranged alternately, and the pixel matrix includes (M×N) pixels P11-PMN, which are respectively arranged at intersections of corresponding data lines and gate lines. For example, the pixels Pm1 to PmN in the mth column of the pixel matrix (m is a positive integer less than M) are set between two adjacent data lines DLm and DL(m+1), and the pixels Pm1 and Pm3...

Abstract

The liquid crystal display includes a plurality of data line groups, a plurality of gate line groups, a pixel array, and a source driving circuit. The odd group of pixels in the mth pixel column of the pixel array is coupled to the Mth data line and the corresponding odd gate line group, and the even group of pixels is coupled to the (M+1)th data line and the corresponding Even-numbered gate line groups. The odd group of pixels in the (m+1)th pixel column of the pixel array is coupled to the (M+1)th data line and the corresponding odd-numbered gate line group, and the even group of pixels is coupled to the (M+2th) ) data lines and corresponding even-numbered gate line groups. The source driving circuit respectively outputs data driving signals with first and second polarities to odd and even data line groups to provide multi-point inversion.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a liquid crystal display with multi-point inversion. Background technique [0002] Liquid crystal display (liquid crystal display, LCD) has the advantages of low radiation, small size and low energy consumption, and has gradually replaced the traditional cathode ray tube display (cathode ray tube display, CRT), so it is widely used in notebook computers, personal Information products such as digital assistants (personal digital assistant, PDA), flat-screen TVs, or mobile phones. [0003] Please refer to figure 1 , figure 1 It is a schematic diagram of a liquid crystal display 100 in the prior art. The liquid crystal display 100 includes a gate driver circuit (gate driver) 110 , a source electrode driver circuit (source driver) 120 , and a liquid crystal display panel 130 . The liquid crystal display panel 130 is provided with a plurality of data lines DL1 -DLM parallel to each othe...
