Embodiment Construction

[0030] The invention provides a vertical alignment type liquid crystal display, which comprises: multiple data lines, multiple scanning lines, and multiple common electrode lines.

[0031] A plurality of scanning lines, a plurality of data lines, and a plurality of common electrode lines are vertically intersected to form a plurality of pixel areas arranged in an array; the plurality of common electrode lines and the plurality of data lines are arranged at intervals and uniformly.

[0032] The multiple pixel areas include multiple sub-pixel areas and multiple main pixel areas, and the multiple sub-pixel areas and the multiple main pixel areas are spaced apart from each other.

[0033] The sub-pixel area includes a first thin film transistor, a second thin film transistor and a sub-pixel, the gate of the first thin film transistor and the gate of the second thin film transistor are connected on the same scanning line, and the drain of the first thin film transistor The electrod...

Abstract

The present invention provides a vertical alignment liquid crystal display, which includes: multiple data lines, multiple scan lines, and multiple common electrode lines; multiple scan lines, multiple data lines, and multiple common electrode lines vertically intersect to form multiple a plurality of pixel areas; a plurality of sub-pixel areas and a plurality of main pixel areas are spaced apart from each other; the sub-pixel area includes a first thin film transistor, a second thin film transistor and sub-pixels, a gate of the first thin film transistor and a gate of the second thin film transistor connected to the same scanning line, and the drain of the first thin film transistor and the drain of the second thin film transistor are respectively connected to the adjacent data line and common electrode line, the source of the first thin film transistor and the second thin film transistor The sources of the transistors are all connected to the sub-pixels; the main pixel area includes the third thin film transistor and the sub-pixels. The invention can improve the defects of the liquid crystal display such as angle deviation and contrast drop.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a vertical alignment liquid crystal display. Background technique [0002] Liquid crystal display is currently the most widely used flat panel display, and has gradually become widely used in various electronic devices such as mobile phones, personal digital assistants (PDA, Personal Digital Assistant), digital cameras, computer screens or notebook computer screens with high resolution. rate color screen monitor. The liquid crystal display commonly used at present usually consists of upper and lower substrates and a middle liquid crystal layer, and the substrate is composed of glass and electrodes. If there are electrodes on the upper and lower substrates, displays in vertical electric field mode can be formed, such as TN (Twist Nematic, twisted nematic) mode, VA (Vertical Alignment, vertical alignment type) mode, and MVA (Multi -domain VerticalAlignment, multi-domain vertical...
