Abstract

The present invention discloses a driving circuit and a liquid crystal display device. The driving circuit is provided with a timing controller, a gate driving circuit and a source driving circuit. When a power saving display mode is started, gate driving signals output by each gate driving unit in the same sub-gate driving circuit are the same, and the number of times of switching of source driving signals output by the source driving circuit is 1 / m of the number of times of that in a color mode, so that the output signals of the gate driving circuit and the source driving circuit are changed to effectively save electricity and realize the switching of a display frame from a color mode to a black-and-white mode.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a driving circuit and a liquid crystal display device. Background technique [0002] Liquid Crystal Display (LCD) has the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and currently occupies a dominant position in the field of flat panel display. With the development and progress of liquid crystal display technology, people put forward higher requirements for the display quality, appearance design, high resolution, low power consumption and other characteristics of liquid crystal displays. [0003] figure 1 It is a schematic diagram of a partial equivalent circuit structure of an existing liquid crystal display device. The liquid crystal display device includes a display panel and a driving circuit. The display panel includes a plurality of pixel units, and each pixel...
