Problems solved by technology

However, in this method, there is a gap between the light-emitting diode light sources and the light guide plate, so that some light rays at specific angles cannot enter the light guide plate, resulting in light leakage, thereby reducing the utilization rate of light.

Embodiment Construction

[0013] figure 1 A three-dimensional schematic diagram of a backlight module provided by a preferred embodiment of the present invention. The backlight module 1 includes a light guide plate 10 , a plurality of LED light sources 20 and a transparent glue 30 fixing the plurality of LED light sources 20 to one side of the light guide plate 10 .

[0014] The light guide plate 10 is a thin flat plate, which has an upper surface 11 and a lower surface 12 arranged oppositely and in parallel, and four sides 13 connecting the upper surface 11 and the lower surface 12 . In this embodiment, the side surfaces 13 are perpendicular to the upper surface 11 and the lower surface 12 respectively.

[0015] Please also see figure 2 , the plurality of LED light sources 20 are disposed on one side 13 of the light guide plate 10 , and are all fixed to the same side 13 by glue 30 . The LED light source 20 includes a light-emitting layer 21 inside, and the light emitted by the LED light source 20 ...

Abstract

A backlight module comprises a light guide plate, a plurality of light-emitting diode light sources arranged in the side direction of the light guide plate, and a glue body fixing the light-emitting diode light sources to the light guide plate.

Description

technical field [0001] The invention relates to a backlight module, in particular to a backlight module which improves the utilization rate of light. Background technique [0002] Compared with traditional light sources, light emitting diodes (Light Emitting Diode, LED) have the advantages of light weight, small size, low pollution, long life, etc. As a new type of light source, it has been increasingly used in in various fields. [0003] However, the backlight module of the liquid crystal panel generally includes a light guide plate and a plurality of LED light sources disposed on one side of the light guide plate. The plurality of light emitting diode light sources are generally fastened to the light guide plate through a mechanism with a plastic frame. However, in all these methods, there is a gap between the plurality of LED light sources and the light guide plate, so that some light rays at specific angles cannot enter the light guide plate, resulting in light leakage...
