Abstract

The invention discloses a liquid crystal display device and a driving method thereof, wherein the liquid crystal display device comprises the components of a liquid crystal display panel which comprises M*N subpixel units; a source electrode driving module which is used for generating a data signal voltage, wherein the source electrode driving module comprises N / 2 output channels; a data control module which comprises a plurality of first switches and a plurality of second switches, the plurality of first switches connect the N / 2 output channels with N / 2 subpixel units in one-to-one correspondence, and the plurality of second switches connect the N / 2 output channels with the rest N / 2 subpixel units in one-to-one correspondence; and a switch driving module which is connected with the first switch and the second switch, wherein in the on time of a line of subpixel units, the switch driving module makes the first switch and the second switch perform switching operation, thereby supplying a data signal voltage which is output from the output channel to a corresponding subpixel unit, wherein M and N are positive integers.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device and a driving method thereof. Background technique [0002] Liquid crystal display, or LCD (Liquid Crystal Display), is a flat and ultra-thin display device, which consists of a certain number of color or black and white pixels, placed in front of the light source or reflector. Liquid crystal displays have low power consumption, high image quality, small size, and light weight, so they are favored by everyone and become the mainstream of displays. With the development of society, small and medium-sized smartphones and PADs are more and more common in people's lives, and at the same time promote the rapid development of LCD technology. The resolution of LCD ranges from 480P to 720P, and then to the widely used FHD. (Full HD, Full High Definition; resolution is 1080*1920). In addition, in small and medium-sized applications, the refr...
