Display device and its ultra-thin backlight module

Abstract

The invention relates to the technical field of display devices and discloses a display device and an ultra-thin type backlight module of the display device. The ultra-thin type backlight module comprises a back board provided with a backlight chamber, a light-emitting piece arranged on the inner bottom face of the backlight chamber, a reflector sheet arranged below the light-emitting piece and a diffuser plate covering the cavity opening position of the backlight chamber and further comprises a main board and a light source panel which are arranged outside the bottom face of the backlight chamber, the bottom of the backlight chamber is provided with at least one protruding portion protruding to the inner portion of the backlight chamber, the protruding portion is provided with a cavity and a protrusion, and the main board and / or the power source panel are / is arranged in the cavity. Due to the fact that the cavity of the protruding portion has a certain depth, after the main board and / or the power source panel are / is arranged in the cavity, a certain distance further exists between the main board and / or the power source panel and the portion outside the back board, namely the certain distance exits between the main board and / or the power source panel and the outer side of the cavity, and therefore when the ultra-thin type backlight module is installed on the display device, the additional safety distance does not need to be reserved between the rear shell and the back board, the overall thickness is reduced, and the requirement for the light and thin development is satisfied.

Description

technical field [0001] The invention belongs to the technical field of display devices, and in particular relates to a display device and an ultra-thin backlight module thereof. Background technique [0002] In the existing backlight module, the matrix arrangement method adopted by the light strips is generally that the light strips are on the same plane, and the light row area of ​​the back panel is basically a large plane. This arrangement method has lower requirements for the light strips. The layout is relatively simple and fixed. However, due to the limitation of the light mixing distance, the space inside the module is not fully utilized, and the thickness of the whole machine is too large to be thinned; the visual effect of matrix lighting on the surrounding and four corners is often difficult to adjust. [0003] This arrangement method is as follows: the light strips are arranged on the back panel, the power board is placed outside the back board, and a safe distanc...

AI Technical Summary

Problems solved by technology

If the light mixing distance is reduced, there will be a problem of poor visual effect, so the light mixing distance cannot be reduced, so the thickness of the whole machine cannot be reduced

Moreover, with this arrangement, the central brightness is relatively high and the surrounding brightness is low. Even if the backlight power is increased, the relative visual effect of the surrounding area is still dark. Adjusting the folding angle of the reflector is often not ideal.
