Backlight module

Abstract

The invention relates to a backlight module, which sets the light source at the back of LCD to uniformly radiate the LCD screen, wherein said invention comprises: a light source, a light guide plate for guiding the light from the light source, a dual-surface adhesive for limiting the light range of light source, and an array lens unit between the light source and the light guide plate for angling the light. Said array lens comprises small lens, the first lens plate horizontally mounted, small lens, and the second lens plate angled mounted with the first lens plate. And the first and second lens plates can angle the light of light source, between the light source and the light guide plate; said lens plate can make brightness uniform; and when the small lens on the first and second lens plates has one angle, the mol phenomenon can be eliminated.

Description

technical field [0001] The invention relates to a backlight module, in particular to a backlight module in which a light source is placed on the back of an LCD so as to evenly illuminate the LCD screen. Background technique [0002] The invention relates to a backlight module, in particular to a backlight module in which a light source is placed on the back of an LCD so as to evenly illuminate the LCD screen. The object of the present invention is to provide a backlight module which ensures uniformity and adequacy of the brightness of the entire display screen. [0003] The invention relates to a backlight module for a display device, in particular to a backlight module for a display device that can ensure high brightness and a wide viewing angle. [0004] A display device using a liquid crystal panel (for example, a mobile phone) illuminates the panel with light emitted by a light source called a backlight unit (Back-Light Unit) and displays an image. [0005] The backlig...

[0010] However, in this existing backlight module for display devices, since the light rays on the surface of the prism sheet are almost completely refracted and reflected after being refracted and reflected in a transverse manner relative to the surface of the light guide plate, the triangular cross-sectional micro-patterns on the surface of the prism sheet are concentrated as follows: image 3 As shown by the curve in , although high-brightness and vivid images can be seen clearly when viewed at a viewing angle of 0 degrees, the larger the viewing angle, the weaker the brightness and the moire phenomenon will appear

[0011] Moreover, when the array lens unit is inserted into the support frame in the prior art, the array lens unit is shaken due to the inability to fix the array lens unit.
