Abstract
The invention discloses a light guide plate, which comprises a light guide plate body and a plurality of convex parts arranged on the top surface of the light guide plate body, wherein each convex part is a frustum of a cone or a frustum of a prism, and the top part is subjected to atomization; and the angles between the peripheral walls of the convex parts and the top surface of the light guide plate body are all acute angles. The invention also discloses a backlight module. As the top surfaces of the light guide plate body is provided with the convex parts and the angles between the peripheral walls of the convex parts and the top surface of the light guide plate body are acute angles, divergence treatment can be carried out on light emitted from a light emitting surface, the convex parts can replace diffusion sheets completely after the top parts are subjected to atomization, the atomization effects can be ensured, the backlight brightness is also ensured, and the assembly efficiency of the backlight module and the assembly efficiency of a display device are greatly enhanced.
Description
Technical field
The present invention relates to display technique field, particularly relate to a kind of light guide plate and backlight module.
Background technology
Diffusion sheet is one of backlight module composition, and major function provides a uniform area source for display.The composition of the material of backlight module is followed successively by reflector plate, light guide plate, lower diffusion sheet, prismatic lens and upper diffusion sheet from bottom to up.Diffusion sheet principle of work is atomized by light source by means of the refraction and reflection that have diffusate, and light is focused on front to improve frontal luminance by low-angle bright dipping; The light sent from light guide plate mainly puts together and evenly projects on prismatic lens by lower diffusion sheet, and the Main Function of upper diffusion sheet is the optical haze penetrated by prismatic lens, and is evenly appeared by light.
Based on factors such as the assembling speed improved when producing and reduction time costs, some designs can take into account omission diffusion sheet, meanwhile, wrap up at the exiting surface of light guide plate the Ya Like material that one deck has mist degree, so just can reach light guide plate surface atomization, also serve the effect omitting diffusion sheet.But the mist degree size of this layer of Ya Like material is difficult to control, and probably greatly reduces backlight illumination because mist degree is too high.
Summary of the invention
In view of the deficiency that prior art exists, the invention provides a kind of atomizing effect is good, brightness is high light guide plate and backlight module.
In order to realize above-mentioned object, present invention employs following technical scheme:
A kind of light guide plate, comprise multiple lug bosses of light conducting plate body and the end face array in described light conducting plate body, described lug boss is round platform or terrace with edge and top atomization process, and the angle between the perisporium of described lug boss and the end face of described light conducting plate body is acute angle.
Further, the surface roughening process of each described lug boss.
Or each described lug boss surface is pasted with atomizing layer.
Further, the end face of each described lug boss is convexly equipped with the first projection of some point-like.
Further, the second projection of at least one point-like is also convexly equipped with between two adjacent described lug bosses.
Another object of the present invention is to provide a kind of backlight module, comprise light guide plate and the light source assembly being located at described light guide plate incident side, described light guide plate comprises multiple lug bosses of light conducting plate body and the end face array in described light conducting plate body, described lug boss is round platform or terrace with edge and top atomization process, and the angle between the perisporium of described lug boss and the end face of described light conducting plate body is acute angle.
Further, the surface roughening process of each described lug boss.
Or each described lug boss surface is pasted with atomizing layer.
Further, the end face of each described lug boss is convexly equipped with the first projection of some point-like.
Further, the second projection of at least one point-like is also convexly equipped with between two adjacent described lug bosses.
The end face of light conducting plate body of the present invention has lug boss, the perisporium of lug boss and the end face of light conducting plate body are acute angle, process can be dispersed to the light that exiting surface sends, and lug boss top can replace diffusion sheet completely after atomization process, both had atomizing effect and also ensure that backlight illumination, the packaging efficiency of backlight module and display device significantly promotes.

Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment 1
Consult Fig. 1 and Fig. 2, the backlight module of the present embodiment comprises light guide plate 10 and is located at the light source assembly 20 of incident side of light guide plate 10, wherein, this light guide plate 10 comprises multiple lug bosses 12 of light conducting plate body 11 and the end face array in light conducting plate body 11, lug boss 12 is round platform or terrace with edge, its top has atomizing effect after atomization process, and between the perisporium of lug boss 12 and the end face of light conducting plate body 11, angulation is acute angle.
After the reflection of the light being incident upon light guide plate 10 through light source assembly 20 through inside and refraction, exiting surface from top penetrates, and due to the existence of lug boss 12, penetrates on the one hand from the light of exiting surface injection through the perisporium of the inclination of lug boss 12, to disperse towards surrounding, form uniform backlight illumination; On the other hand, penetrate after the atomization at the top of lug boss 12, while forming atomizing effect, also ensure that backlight illumination.
During atomization process, each lug boss 12 surface can roughening process to realize atomization, or, by attaching the realization of atomization tunic on each lug boss 12 surface.
The present embodiment has the first protruding 12a of some point-like (namely hemispherical) at the end face array of each lug boss 12, degree of divergence can regulate by changing the degree of tilt of lug boss 12, and fogging degree can regulate by arranging the quantity of the first protruding 12a, size and array density.
By such setting, light guide plate can once injection moulding, only needs designing mould that light guide plate exiting surface can be made to have and disperses and atomizing effect, directly eliminate diffusion sheet; Meanwhile, deviser can change fogging degree and degree of divergence according to different atomization demands, practical; While saving diffusion sheet, also eliminate the operation of assembling diffusion sheet, need not worry to paste partially or be pasted not strongly, indirectly improve the speed of production of product.
Embodiment 2
As shown in Figure 3 and Figure 4, as different from Example 1, the compartment between two adjacent lug bosses 12 of the present embodiment is also convexly equipped with the second projection 13 of point-like (namely hemispherical).Second projection 13 can play the effect dispersed and be atomized simultaneously, strengthens overall brightness to a certain extent, improves display effect.
The present invention arranges lug boss by the end face in light conducting plate body, the perisporium of lug boss and the end face of light conducting plate body are acute angle, process can be dispersed to the light that exiting surface sends, and lug boss top can replace diffusion sheet completely after atomization process, both had atomizing effect and also ensure that backlight illumination, the packaging efficiency of backlight module and display device significantly promotes.
