Abstract

The invention discloses a display module, a driving method thereof and a display device, which relate to the technical field of display. The display device comprises a display module, which is provided with a display area and a non-display area. The display module includes a display panel including a plurality of pixel unit rows and a gate driving circuit, wherein the gate driving circuit sends adriving signal to the pixel unit rows; a backlight module comprising a plurality of LED lights and a backlight driving circuit, wherein the backlight driving circuit sends a start signal to the LED lights; and a control chip electrically connected to the gate driving circuit and the sub-pixel unit and transmitting a data signal to the sub-pixel unit; wherein the backlight driving circuit is further electrically connected to the gate driving circuit, and a first trigger signal sent by the gate driving circuit can be received. The first trigger signal is provided to the backlight driving circuitthrough the gate driving circuit, so that the lighting of the LED light in the backlight module is synchronized with the display screen or later than the display screen, and the display effect of thedisplay module and the display device can be increased.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display module, a driving method thereof, and a display device. Background technique [0002] 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 reflective surface. Liquid crystal displays consume very little power, making them favored by engineers for electronic devices that run on batteries. [0003] The working principle of liquid crystal display: Liquid crystal is a special substance between solid and liquid. It is an organic compound, which is liquid under normal conditions, but its molecular arrangement is as regular as solid crystal, so it is named liquid crystal. , Its other special property is that if an electric field is applied to the liquid crystal, its molecular arrangement will be changed. At this time, if it is equipped wit...
