Embodiment Construction

[0031] The invention provides a vertical alignment liquid crystal display, such as image 3 As shown, the liquid crystal display includes: a plurality of data lines D1, D2, D3, D4..., a plurality of scanning lines G1, G2,..., G7..., a plurality of data lines and a plurality of scanning lines intersect to form a plurality of Each pixel area is surrounded by two adjacent data lines and two adjacent scan lines. For example, a pixel area surrounded by the data lines D1, D2 and the scan lines G1, G2.

[0032] Each pixel area includes a switching TFT T1 and a sub-pixel, the gate and drain of the switching TFT T1 are respectively connected to the scan line and the data line, and the source of the switching TFT T1 is connected to the sub-pixel. When the scanning signal on the scanning line turns on the switching thin film transistor, the data signal on the data line is output to the sub-pixels, driving the sub-pixels to emit light.

[0033] In two adjacent pixel regions in the same ...

Abstract

The present invention provides a vertical alignment type liquid crystal display, comprising: a plurality of data lines and a plurality of scanning lines, the plurality of data lines and the plurality of scanning lines intersect to form a plurality of pixel areas, each pixel area is composed of Two adjacent data lines are surrounded by two adjacent scan lines; each pixel area includes a switch thin film transistor and a sub-pixel, and the gate and drain of the switch thin film transistor are respectively connected to the scan lines. connected to the data line, and the source of the switching thin film transistor is connected to the sub-pixel; in two adjacent pixel regions in the same row, a first capacitor is connected in series between the sources of the two switching thin film transistors, And the source of each of the switching thin film transistors is only connected to one of the first capacitors. The invention can improve the shortcomings of the liquid crystal display, such as viewing angle deviation and contrast reduction.

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...
