Embodiment 1

[0032] refer to Figure 1~13 , an edge-type backlight module with light and thin structure, comprising a lower case 1, a lampshade 2, a light bar 3, a light guide plate 4 and a film structure 5. The lower case 1 is used as the overall installation structure of the lampshade 2, the light guide plate 4 and the diaphragm structure 5, and also as the installation structure of the liquid crystal panel of the terminal display; the lower case 1 is preferably made of lightweight plastic parts, and the lower case 1 set the hollow structure at the bottom, such as setting figure 2 A plurality of hollows 13 are arranged in the middle, so that the weight of the backlight module can be reduced while ensuring the structural strength. The light strip 3 is bonded and fixed in the lampshade 2 by heat-conducting double-sided adhesive, and the light strip 3 dissipates heat through the lampshade 2 during operation; and the lampshade 2 can make the light emitted by the light strip 3 illuminate th...

Abstract

The invention discloses a side-entry backlight module with a light and thin structure. The backlight module comprises a lower shell (1), a lamp shade (2), a lamp strip (3), a light guide plate (4) anda diaphragm structure (5). The lamp strip (3) is arranged in the lamp shade (2); the lamp shade (2) is fixedly arranged on the lower shell (1); the light guide plate (4) and the diaphragm structure (5) fixedly arranged in the lower shell (1); the lower shell (1) is a plastic component, and the bottom portion of the lower shell (1) is of a hollow structure; the lamp shade (2) is a metal piece; thelight guide plate (4) is of a wedge structure; the lamp strip (3) enters light from the thicker side of the light guide plate (4); and a mesh point structure is arranged on the light guide plate (4),and mesh points on the light guide plate realize gradual transition from thin to dense from the thicker side to the thinner side. The weight of the backlight module is reduced, and size of the backlight module is thinned.

Description

technical field [0001] The invention relates to the technical field of backlight sources, in particular to a side-entry backlight module with light and thin structure. Background technique [0002] Backlight is a structure that provides a light source for the display device from the back, such as the backlight module of the display. Currently, most of the displays on the market are liquid crystal displays, and liquid crystal displays cannot emit light. The backlight provided by the backlight module is needed to realize the display function. ; and the liquid crystal panel is relatively thin and brittle, and it must be installed and used through the backlight module as a structural part. Therefore, the backlight module is not only the light source of the liquid crystal display, but also a structural part of the liquid crystal display, which is very important for the liquid crystal display. [0003] The backlight module needs to support its own structure and the liquid crystal ...
