Embodiment 1

[0028] figure 2 An exploded view of a backlight module provided in Embodiment 1 of the present invention. The backlight module in this embodiment can be applied to a liquid crystal display to supply sufficient brightness and evenly distributed light sources for the liquid crystal display so that it can display images normally; it can also be used as a light source for mobile phones, tablet computers, and notebook computers.

[0029] The backlight module provided in this embodiment includes:

[0030] Light emitting component 210;

[0031] The front light guide plate 220 is used to convert the light source emitted by the light-emitting component 210 into a surface light source and lead it out from the first light-emitting surface;

[0032] The rear light guide plate 230 is arranged opposite to the front light guide plate 220, and is used to convert the light source emitted by the light-emitting component 210 into a surface light source, and lead it out from the second light-e...

Embodiment 2

[0041] image 3 An exploded view of a backlight module provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. The first optical film set 360 in the backlight module provided by this embodiment includes: a first light enhancement sheet 361 and a first diffusion sheet 362; and a second optical film set 370 includes a second brightness enhancement sheet 371 and a second diffusion sheet 372 .

[0042] The first light enhancement sheet 361 and the second light enhancement sheet 371 can gather the light emitted from the light emitting surfaces of the front light guide plate 330 and the rear light guide plate 340 in a single direction, and the unused light outside the viewing angle is recycled according to the light re-reflection effect, And gathered at the most appropriate angle. In this embodiment, preferably, the internal structure of the diaphragms of the first brightness enhancement sheet 361 and the sec...

Embodiment 3

[0051] Figure 4 An exploded view of a backlight module provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above embodiments, and the front light guide plate 420 and the rear light guide plate 430 of the backlight module provided in this embodiment share the same light-emitting component 410 .

[0052] Preferably, the light-emitting component 410 may be disposed in a receiving groove on at least one side of the reflective component 440 between the front light guide plate 420 and the rear light guide plate 430 .

[0053] After the reflective component 440 is combined with the front light guide plate 420 and the rear light guide plate 430 , there is a receiving groove on at least one side for attaching the light emitting component 410 . Specifically, no reflective member 440 is pasted on at least one side between the front light guide plate 420 and the rear light guide plate 430. The opposite diffusing surface of the rear light ...

Abstract

The embodiment of the invention discloses a backlight module group and an LCD. The backlight module group comprises a lighting part, a front light guiding panel which converts a light source emitted from the lighting part into an area light source led out from a first light-exiting surface, a rear light guiding panel which is arranged opposite to the front light guiding panel and converts a light source emitted from the lighting part into an area light source led out from a second light-exiting surface, a reflecting part positioned between the front light guiding panel and the rear light guiding panel, a first optical film group positioned at the front side of the first light-exiting surface of the front light guiding panel, and a second optical film group positioned at the front side of the second light-exiting surface of the rear light guiding panel. Two iron backboards of the a bi-side displaying LCD are eliminated, thereby effectively reducing the integral thickness of the LCD and lowering cost.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a liquid crystal display. Background technique [0002] With the development of display technology, many products need to display images on both sides of the display screen, and electronic products such as dual-screen mobile phones and dual-screen advertising boards have become popular. However, the dual-screen display products currently on the market are still composed of common display technologies, and two sets of complete common displays, front and back, are installed inside. figure 1 It is an exploded view of a common single-sided display in the prior art. Such as figure 1 As shown, a common single-sided display includes: an iron backboard 110, a reflector 120, a light guide plate 130, an optical film 140, a plastic frame 150, a buffer glue 160, a liquid crystal display 170 and an LED light bar 180, wherein the optical film 140 It includes a bright...
