Embodiment Construction

[0027] see Figure 5 , is a schematic structural view of the first embodiment of the liquid crystal display device of the present invention. The liquid crystal display device 20 includes a printed circuit board (PCB) 21 , ten flexible printed circuit boards (FPCB) 22 and a liquid crystal panel 23 . The printed circuit board 21 is electrically connected to the liquid crystal panel 23 through the flexible printed circuit board 22 .

[0028] Each flexible printed circuit board 22 includes a data driving circuit 24 . The printed circuit board 21 includes a timing control circuit 25 for outputting RGB image signals and polarity inversion control signals to the data driving circuit 24 . The timing control circuit 25 includes a polarity inversion control circuit 26 for controlling the voltage polarity of the data signal output by the data driving circuit 24 .

[0029] Please also refer to Figure 6 ,yes Figure 5 The internal circuit diagram of the polarity inversion control circu...

Abstract

The invention relates to a liquid crystal display device and a driving method. The liquid crystal display device comprises a plurality of data drive circuits, a data processing unit and two control units; the data processing unit transmits control signals to the two control units respectively, wherein, one control unit controls the voltage polarity of the data signals outputted by part of the data drive circuits to be unchanged, and the other control unit controls the voltage polarity of the data signals outputted by the rest data drive circuits to be changed so as to eliminate crosstalk interference.

Description

technical field [0001] The invention relates to a liquid crystal display device and a driving method thereof. Background technique [0002] Liquid crystal display devices are widely used in fields such as mobile phones, personal digital assistants, notebook computers, and televisions due to their small size, low radiation, and low power consumption. Generally, a liquid crystal display device controls the rotation of liquid crystal molecules in the liquid crystal layer by changing the voltage across the liquid crystal layer, thereby controlling the amount of light passing through the liquid crystal layer to achieve the purpose of display. [0003] When the liquid crystal display device displays static images, that is, when the same electric field is always applied to drive the liquid crystal molecules, the response of the liquid crystal molecules to the electric field will gradually become dull. In order to avoid this problem, the direction of the electric field applied to t...
