Embodiment Construction

[0047] In order to solve the problem of light leakage in the dark state of the pixel unit or insufficient brightness of the image in the dark state in the traditional display device, the present invention provides a display device. The display device is provided with a control panel on the side where the backlight module emits light. The control panel includes a plurality of control units, the control units are in one-to-one correspondence with the positions of the pixel units, and the control units have two working states of light-transmitting and light-proof. By setting the control module, when the pixel unit is in the dark state, the corresponding control unit is controlled to be opaque, and when the pixel unit is in the bright state, the corresponding control unit is controlled to transmit light, which can effectively improve the dark state of the pixel unit. The phenomenon that the brightness of the dark state picture is not low enough makes the dark state of the pixel uni...

Abstract

The invention relates to the technical field of display, and discloses a display device. According to the display device, a control panel is arranged on the side, emitting light, of a backlight module, the control module comprises a plurality of control units, the control units correspond to the positions of pixel units of the display panel one to one, and each control unit has a light-transmitting work state and a light-proof work state. When the pixel units are set to be in a dark state, the corresponding control units are in the light-proof state. When the pixel units are in the bright state, the corresponding control units are in the light-transmitting state. The phenomenon that light is leaked in the dark state of the pixel units or the image brightness is not low enough in the dark state can be effectively reduced, the pixel units can be dark enough in the dark state, the image contrast ratio is improved, and image display quality is guaranteed.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] Liquid crystal display devices have the characteristics of small size, low power consumption, no radiation, relatively low manufacturing cost, etc., and occupy a dominant position in the current flat panel display market. The principle of the liquid crystal display device is to control the deflection of liquid crystal molecules by driving an electric field to realize the display of a specific gray scale. [0003] In order to arrange the liquid crystal molecules according to a certain alignment rule, an alignment layer is formed inside the liquid crystal panel. However, liquid crystal molecules close to the alignment layer are affected by the riveting force of the alignment layer, and their deflection is seriously affected. As a result, in traditional liquid crystal display devices, it is easy to have light leakage in the d...
