Light guide plate, backlight module, liquid crystal display device and electric equipment

Abstract

The invention relates to a light guide plate which comprises a first accommodating space, a second accommodating space and a third accommodating space, wherein the first accommodating space is used for fixing a liquid crystal panel; the second accommodating space is used for configuring an optical membrane set; and the third accommodating space is used for configuring a light source unit. Due to the functions of the first accommodating space, the second accommodating space and the third accommodating space of the light guide plate, the accommodating functions of a back shell and a rubber frame of a known backlight module can be replaced, and the liquid crystal panel, the optical membrane set and the light source unit are directly accommodated on the light guide plate, thus the back shell and the rubber frame can be cancelled so as to ensure that the thickness of the backlight module can become thinner. Meanwhile, the design of a clamping hook can be cancelled, thus the backlight module can be simpler to assemble and has lower cost, and the automation of the backlight module can also be introduced.

Description

technical field [0001] The present invention relates to a liquid crystal display device, more particularly to a backlight module, the functions of the first, second and third accommodating spaces of the light guide plate can directly connect the liquid crystal panel, the optical film group And the light source unit is placed on the light guide plate. Background technique [0002] With the advancement of electronic technology, especially the popularity of portable electronic products in daily life, there is an increasing demand for displays that are thin, light, small, and low in power consumption. Due to the advantages of low power consumption, low heat generation, and light weight, liquid crystal displays (Liquid Crystal Displays; LCDs) are often used in such electronic products and have gradually replaced traditional cathode ray tube displays. [0003] refer to figure 1 , the known liquid crystal display device 10 mainly includes a front frame 12 , a liquid crystal panel...

AI Technical Summary

Problems solved by technology

The backlight module 20 further includes a back shell 32 and a plastic frame 34, wherein the back shell 32 is combined with the plastic frame 34 to connect the light guide plate 22, the lamp tube 24, the U-shaped reflector 26, the optical film group 30 and The reflector 28 is fixed between the back shell 32 and the plastic frame 34. Therefore, when the backlight module 20 is assembled, it is usually necessary to design fixing methods such as hooks, which not only consume man-hours of manual assembly, but also often have the problem of poor fitting of the hooks.
