Light guide plate installing structure

Abstract

The invention relates to the technical field of light display structures and discloses a light guide plate installing structure. The light guide plate installing structure comprises a light guide plate, a back plate and a plastic frame, wherein the light guide plate, the back plate and the plastic frame are arranged in sequence. The light guide plate comprises a first face and a second face which are arranged oppositely. The second face faces the back plate. The four vertex angles of the first face of the light guide plate are provided with clamping positions recessed downwards. A protruding lug protruding outwards is arranged on the side wall of the middle of the light guide plate. Protruding ribs matched with the clamping positions are arranged on the four vertex angles of the inner ring of the plastic frame. A locating groove matched with the protruding lug is formed in the middle of the inner ring of the plastic frame. A groove is formed in the second face of the light guide plate. A rib plate matched with the groove is arranged on the back plate and used for locating the light guide plate and limiting expansion of the light guide plate in the installation process. According to the light guide plate installing structure, the thin light guide plate can be effectively prevented from being deformed, the light guide plate can be accurately located in the installation process, and the phenomenon that the light guide plate is prone to deformation due to the fact that the light guide plate is heated and expands is avoided.

Description

technical field [0001] The invention relates to the technical field of light display structures, in particular to a light guide plate installation structure. Background technique [0002] After years of development, liquid crystal display technology has gradually become a leader in display technology. The liquid crystal display screen produced with its technical support has become an indispensable and important component of display devices such as tablets and mobile phones. However, since the liquid crystal display panel itself does not emit light, it is necessary to arrange a backlight module under the liquid crystal display panel. [0003] Common distribution forms of light sources in liquid crystal display screens commonly used in the prior art are divided into bottom backlight and side backlight. For LCD screens that use side backlight to set the light source, the light guide plate is the most important optical component. The light source is set on the side of the light...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to propose a light guide plate installation structure to solve the problems in the prior art that the light guide plate is not easy to install and easy to be damaged during the installation process due to the thinner light guide plate.

[0007] Another object of the present invention is to propose a light guide plate installation structure to solve the problem in the prior art that the light guide plate is not positioned accurately during the installation process, and is easily deformed due to thermal expansion, resulting in a short service life.
