Liquid crystal display module and support device thereof

Abstract

The invention provides a support device of a liquid crystal display module and comprises a backboard which is provided with a bottom plate and a plurality of support plates; the bottom plate is provided with a reflection plate, a light guide plate and an optical membrane module; the support device also comprises a rubber frame; a plurality of platforms extend out from the rubber frame and are arranged on the upward side of the optical membrane module, moreover, certain space is remained between the platforms and the optical membrane module; at least one platform is provided with a convex rib and the optical membrane module is provided with a through hole corresponding to the convex rib, moreover, each convex rib gets through the corresponding through hole on the optical membrane module and plays a role of support between the platform and the light guide plate. As the support point of the convex rib providing support for the platform is close to the free terminal of the platform, the convex rib can ensure the distance between the platform and the optical membrane module and prevent the optical membrane module from waving deformation under high temperature state.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display module and its supporting device, in particular to a supporting device of a liquid crystal display module. 【Background technique】 [0002] 1, the existing liquid crystal display module includes a liquid crystal display panel 11, a backlight module 12 arranged behind the liquid crystal display panel 11 to provide light to the liquid crystal display panel, and a supporting device for supporting and fixing the liquid crystal display panel. The display panel 11 and the backlight module 12 . The supporting device includes a back plate 13 , a plastic frame 14 and an annular glass plate 15 covering the plastic frame 14 , so that the liquid crystal display panel 11 is covered on the glass plate 15 . The supporting device and the liquid crystal display panel 11 are surrounded by a frame 16, and then the liquid crystal display module is installed in the shell of the liquid crystal display device. The back pla...

Problems solved by technology

However, in the above-mentioned existing liquid crystal display device, the platform 142 is only supported by the support plate 132, and the following problems are likely to occur: that is, when the glass plate 15 is installed on the platform 142, and the liquid crystal display panel 11 is installed on the glass plate 15 and rests on it. After a free end 1421 of the platform 142, because the support plate 132 is far away from a free end 1421 of the platform 142 to a supporting point 1420 of the platform 142, it is easy to make the platform 142 deform due to the force, causing the platform 142 to be in contact with the optics. The distance d1 between the diaphragm groups 123 cannot be maintained between 0.15-0.2 millimeters, but is lower than the ideal value. Therefore, when the optical diaphragm group 123 is under the action of heat from the light source, especially when it is subjected to a high temperature test When it is heated, it is easy to cause waving deformation due to insufficient space for thermal expansion, which will affect the picture effect of the liquid crystal display device, and even cause the optical film group to fall off.
