A display device and electronic device

Abstract

The embodiment of the invention discloses a display device and an electronic device. The display device comprises a liquid crystal display panel, n backlight modules and n backlight control circuits,wherein the liquid crystal display panel comprises n display areas which are arranged in sequence; the n backlight modules are used for providing display backlight for the corresponding display areas;the n backlight control circuits are used for transmitting backlight control signals to the corresponding backlight modules, when the ith display area is scanned, the ith backlight control circuit controls a transmission path of the backlight control signal and the corresponding backlight module to be disconnected, and the remaining (n-1) backlight control circuits control the transmission pathsof the backlight control signals and the corresponding backlight modules to be connected. According to the embodiment of the invention, the connection / disconnection of the transmission paths of the backlight modules and the backlight control signals is controlled through the backlight control circuits, the backlight power consumption can be reduced, in addition, a control algorithm is simple, thepower consumption of a driving chip can be reduced, and meanwhile, the cost of the driving chip is reduced.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display device and electronic equipment. 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. The liquid crystal display panel of the liquid crystal display does not emit light itself, it is the result of displaying graphics or characters by modulating the light, so the liquid crystal display is usually equipped with a backlight module, which provides a backlight source for the liquid crystal display panel, and its luminescence The effect will directly affect the visual effect of the LCD panel. [0003] In the existing liquid crystal display, the light source of the backlight module is always turned on within one frame, resulting in high power consumption of the backlight module. If the backl...
