Light guide plate and backlight module group

Abstract

The invention discloses a light guide plate and a backlight module group. The light guide plate comprises a main body and a bending light incidence part. The bending light incidence part extends from one side of the main body and bends toward the direction opposite to the bottom of the main body. The bending light inlet part comprises a light incidence end face, a first guide inclined plane and a second guide inclined plane. The light incidence end face is formed on a side surface in opposite direction of the bending light incidence part and the main body so as to receive the light generated by a light source. The first guide inclined plane and the second guide inclined plane are respectively connected with the top edge and the bottom edge of the light incidence end face and are respectively intersected with the main body at a first boundary and a second boundary.

Description

technical field [0001] The invention relates to a backlight module and a light guide plate included in the backlight module; in particular, it relates to a side-light backlight module using light emitting diodes and a light guide plate included in the backlight module. Background technique [0002] Liquid crystal display panels are currently the mainstream of display devices, and are widely used in electronic products such as various panel displays, flat-screen TVs for home use, flat-panel monitors for personal computers and laptops, display screens for mobile phones and digital cameras, etc. . In addition, the edge-lit backlight module in which the light source is arranged around the edge of the light guide plate has a thinner module thickness than the direct-lit backlight module in which the light source is evenly arranged behind the light guide plate, so that the edge-lit flat panel display can be It is more competitive in the market that currently emphasizes thinness. ...

AI Technical Summary

Problems solved by technology

[0006] But the above-mentioned existing edge type backlight module 10 still has the shortcoming on optics

Part of the light generated from the light-emitting diode 11 will pass through the guide slope 32 of the protruding part of the light guide plate 20 or the position of the light guide plate 20 close to the guide slope 32, and thus cause a difference in brightness at the edge of the visible area of ​​the backlight module 10. uneven
