Embodiment Construction

[0014] see figure 1 , which is a structural block diagram of a preferred embodiment of the liquid crystal display device of the present invention. The liquid crystal display device 200 is a liquid crystal display device capable of simultaneously realizing 2D / 3D conversion, and it has two working states of flat display and stereoscopic display. The liquid crystal display device 200 includes a liquid crystal display module 10 and a driving circuit module 20 .

[0015] The liquid crystal display module 10 includes a backlight 11 , a liquid crystal panel 12 and a controllable light valve 13 . The backlight 11 is used to provide a uniform planar light for the liquid crystal panel 12, which may include a plurality of point light sources (such as light emitting diodes) and an optical film for converting the light emitted by the point light sources into planar light Sheet (such as light guide plate, diffusion sheet, etc.). The liquid crystal panel 12 is used for processing the plan...

Abstract

The invention relates to a liquid crystal display device which comprises a display module and a driving circuit module, wherein the display module comprises a backlight source, a liquid crystal panel and a controllable light valve; the driving circuit module comprises a backlight driving circuit, a light valve driving circuit and a control circuit; the backlight driving circuit is used for supplying voltage to the backlight source to drive the backlight source to emit light; the light valve driving circuit is used for controlling the controllable light valve under the action of a display status switching signal, so that the liquid crystal display device can be switched to the corresponding display status; and the control circuit receives the display status switching signal and controls the backlight driving circuit according to the display status switching signal to adjust the brightness of the backlight source.

Description

technical field [0001] The present invention relates to a liquid crystal display technology, in particular to a liquid crystal display device capable of realizing 2D / 3D conversion. Background technique [0002] Due to its advantages of small thickness and low power consumption, liquid crystal display devices are widely used in electronic products, such as mobile phones, game consoles, handheld computers, music players, and the like. Among them, liquid crystal display devices capable of switching between flat display and stereoscopic display (usually referred to as 2D / 3D conversion) have attracted more and more attention from the industry. [0003] A conventional liquid crystal display device usually includes a liquid crystal panel, a backlight source and a driving circuit. Wherein, the backlight source is used to provide a uniform plane light for the liquid crystal panel, and the liquid crystal panel processes the plane light provided by the backlight source under the drive...
