Embodiment Construction

[0022] Certain words are used to refer to specific components in the description and claims, and those skilled in the art should understand that manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a basis for distinction. The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] figure 1 It is a structural schematic diagram of the liquid crystal display of the first embodiment of the present invention. Such as figure 1 As shown, the liquid crystal display includes: a data line S(N) (N is a natural number), a scan line G(N) (N is a natural number), a plurality of pixel units 10 and a control circuit 20 .

[0024] Each pixel unit 10 is connected to a corresponding data line and a scan line. Wherein, each pixel unit 10 includes at least two ...

Abstract

The invention discloses a liquid crystal display and a control method thereof. The liquid crystal display comprises a plurality of data lines, a plurality of scanning lines, a plurality of pixel units and a control circuit, wherein each pixel unit is connected to one corresponding data line and one corresponding scanning line, each pixel unit comprises at least two different colors of sub-pixels which are arranged in sequence, and the at least two different colors of sub-pixels are charged by the same corresponding data line; the control circuit receives a plurality of control signals, and controls the different colors of sub-pixels in the plurality of pixel units to be charged simultaneously according to the plurality of control signals; and the plurality of control signals are effective in a time-sharing mode in a scanning period of one scanning line, thereby completing charging for all sub-pixels corresponding to the scanning line in the scanning period. According to the method disclosed by the invention, the liquid crystal display controls the sub-pixels charged at the same moment to be not sub-pixels of a single color in the charging process, thereby improving a problem of nonuniform brightness of the liquid crystal display during a charge switching period.

Description

technical field [0001] The invention relates to the field of liquid crystals, in particular to a liquid crystal display and a control method thereof. Background technique [0002] With the development of liquid crystal displays (Liquid Crystal Display, LCD), people have higher and higher requirements on the resolution of the LCD. Due to the increase in resolution, the number of data lines (sourcelines) required for output control is also increasing. In order to reduce the output quantity of the sourceline of the LCD driver chip, the same data line can be used to charge multiple sub-pixels (sub-pixels) of different colors in a MUX switching manner. [0003] Wherein, in the process of charging, the technical solution adopted in the prior art is to charge only the sub-pixels of the same color at the same charging moment. That is to say, taking the sub-pixels of three different colors in the liquid crystal display as an example, in the charging process, the sub-pixels of the fi...
