Abstract

The LCD display comprises multi data lines, multi grid lines, multi display units, two virtual grid lines and multi virtual switches. In positive polarity cycle, using the virtual grid lines and virtual switches to connect the corresponding data lines to the positive source in order to execute the charge sharing; in negative polarity cycle, using the virtual grid lines and virtual switches to connect the corresponding data lines to the negative voltage source to execute the charge sharing.

Description

technical field [0001] The present invention relates to a liquid crystal display device, in particular to a liquid crystal display device capable of reducing energy consumption through charge sharing. Background technique [0002] Due to the advantages of low radiation, small size and low energy consumption, liquid crystal displays have gradually replaced traditional cathode ray tube displays, and are therefore widely used in notebook computers, personal digital assistants ( personaldigital assistant, PDA), flat-screen TV, or information products such as mobile phones. [0003] Please refer to FIG. 1 , which is a schematic diagram of a liquid crystal display 10 in the prior art. The liquid crystal display 10 includes a liquid crystal display panel 12 , a timing controller 14 , a source driver 16 , and a gate driver 18 . The liquid crystal display panel 12 is provided with a plurality of parallel data lines (data lines) D 1 -D m , a plurality of parallel gate lines (gatel...
