Liquid crystal display apparatus and drive method thereof

Abstract

The invention discloses an LCD device and a drive method thereof. In the technical proposal thereof, the LCD device comprises a plurality of first gate lines, a plurality of second gate lines, a plurality of data lines, and a plurality of pixels arranged in the area where the first gate lines are crossed with the data lines and distributed in matrix shape, wherein each pixel comprises a first thinfilm transistor, a second thin film transistor, a third thin film transistor, a fourth thin film transistor, a first sub-pixel electrode, a second sub-pixel electrode and a charge shared capacitor. The LCD device and the drive method enable two sub-pixels to form different voltages through the voltage of the charge shared capacitor, thereby representing colors having larger bit number with a datadriver having smaller bit number, improving the color repeatability and saving the cost.

Description

technical field [0001] The invention relates to a liquid crystal display device and a driving method thereof, in particular to a liquid crystal display device with improved color reproducibility and a driving method thereof. Background technique [0002] Liquid crystal displays are currently one of the most widely used types of flat panel display devices. A liquid crystal display generally includes an array substrate and a color filter substrate, and a liquid crystal layer interposed between two substrates having pixel electrodes and a common electrode for generating an electric field. A liquid crystal display displays images by applying a voltage to electrodes to generate an electric field in a liquid crystal layer. [0003] like figure 1 As shown, the liquid crystal display includes: a liquid crystal display panel 10, which has a pixel matrix; a gate driver 20, which is used to drive and gate the gate lines GL of the liquid crystal display panel 10; The data line DL is ...

AI Technical Summary

Problems solved by technology

[0007] In order to achieve a color with a relatively large number of bits using a data driver with a relatively small number of bits, the current existing method is to temporarily combine several frame units and represent them by spatially combining several pixels or increasing the number of cases. Center point method to achieve, but this method is likely to cause problems such as resolution reduction or flickering
