A kind of driving structure and liquid crystal display device

Abstract

The invention provides a driving architecture and a liquid crystal display device. The driving architecture comprises sub-pixels in matrix distribution, a first source driver and a second source driver, wherein the sub-pixels are divided into first sub-pixels and second sub-pixels which are arranged at intervals; the first source driver is used for outputting a first driving voltage; and the second source driver is used for outputting a second driving voltage, wherein a voltage difference between the first driving voltage and the second driving voltage is adjustable when the first and second sub-pixels display a same gray scale. The driving architecture and the liquid crystal display device provided by the invention can achieve effective switching between two modes, namely a large-view-angle mode and a high-penetration-rate mode, so that the application scope and flexibility of the liquid crystal display device are enhanced; in the large-view-angle mode, large-view-angle color cast compensation can be achieved, so that a color cast problem of the liquid crystal display device is improved; and in addition, loss in an aperture opening ratio caused by increase in thin-film transistors and capacitors can be prevented.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display panels, in particular to a driving structure and a liquid crystal display device. Background technique [0002] With the continuous application of liquid crystal display devices, people's requirements for the viewing angle of liquid crystal display devices are also gradually increasing. Therefore, liquid crystal display devices with relatively large viewing angles and wide viewing angles, such as VA-type liquid crystal display devices, have been developed. [0003] In the VA (Vertical Alignment) display mode, the design of 8-domain structure is usually used to improve the problem of large viewing angle deviation, that is, by dividing a sub-pixel into a main sub-pixel area and a sub-sub-pixel area, and through the main sub-pixel area of ​​the sub-pixel Different driving voltages are applied to the sub-sub-pixel area to improve the color shift problem. However, the design of ...

Problems solved by technology

However, the design of the 8-domain structure requires multiple thin film transistors and corresponding capacitors to be jointly driven, which will seriously affect the aperture ratio of the pixel; Applying a different driving voltage to the sub-sub-pixel area causes the brightness of the sub-sub-pixel area to be low, which reduces the transmittance of the liquid crystal display device, that is, the existing liquid crystal display device can only operate in low color shift and high transmittance. choice, less flexibility
