Problems solved by technology

[0004] However, in the 8-domain structure, in addition to the need for additional thin film transistor structures and corresponding capacitor structures, the existence of these structures will reduce the aperture ratio of the pixel.
In addition, the existing color shift compensation is to improve the color shift of the liquid crystal panel by lowering the brightness of the sub-domains. As the overall brightness decreases, the light transmittance of the liquid crystal display panel will also decrease, which seriously affects the display quality of the liquid crystal display.

Abstract

The invention provides a driving method of a liquid crystal display. The driving method of the liquid crystal display comprises steps that a time schedule controller is used to output a source electrode enabling signal to a source electrode driver, and is used to output grid electrode enabling signal to a grid electrode driver; the source electrode driver is used to receive the source electrode enabling signal, and a duty ratio of a source electrode driving signal output to a source electrode line is reduced based on the source electrode enabling signal; the grid electrode driver is used to receive the grid electrode enabling signal, and a duty ratio of a grid electrode driving signal output to a grid electrode line is reduced based on the grid electrode enabling signal. The invention also provides the liquid crystal display and an electronic device. The liquid crystal display can be provided with a four-domain structure, and a quantity of electronic components is reduced based on improvement of color cast, and then an aperture ratio of a pixel is improved.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a liquid crystal display, a driving method thereof, and an electronic device. Background technique [0002] The VA (Vertical Alignment, vertical alignment) display mode has become a common display mode for large-size TFT-LCDs due to its advantages of high contrast and no need for frictional alignment. The problem of color shift under different viewing angles is a major issue that must be faced in the design of VA display mode products. [0003] At present, the design of 8-domain structure is the usual method for VA display mode to improve the problem of large viewing angle deviation. In the 8-domain structure, due to the charge sharing effect, the potential of the sub-domain (Sub Domain) is lower than that of the main domain (Main Domain), so that the sub-domain and the main domain can display different brightness, so as to control the different orient...
