Abstract
A kind of light guide plate, comprises incidence surface and bottom surface and the exiting surface relative with this bottom surface, described exiting surface is arranged protruding arc strip tape, the parallel and each arc strip interband of adjacent arc strip tape every distance equal; With the straight line residing for described arc strip tape for benchmark, be incidence surface with a side of the light guide plate of described linear vertical; Described bottom surface is dot surface.The arc of described arc strip tape is a part for standard round.The utility model passes through reasonably to arrange the width of arc strip tape and the spacing distance of height and two arc strip tapes, make light guide plate luminance of the present utility model improve and brightness is more even, adopt resin material good fluidity, simultaneously the utility model does not have horn structure, effectively can slow down light guide plate and optical film material because of the scuffing caused that rubs.
Description
Technical field
The utility model relates to a kind of light guide plate, particularly relates to a kind of light guide plate for LCD MODULE (LCM).
Background technology
Along with the market demand of the slimming of the terminal electronic such as mobile phone, flat board product, low energy consumption, high colour gamut and ultra-narrow frame is more and more tighter, require also more and more higher to the backlight of its LCD MODULE LCM.Light guide plate is as the core component of backlight, and its thickness and optical characteristics play vital effect to the thickness and lifting brightness, uniformity coefficient and picture display effect aspect that reduce backlight finished product.At present, industry Nei Ge producer is all devoted to have breakthrough in light guide board microstructure, especially updates in light guide plate V-CUT structural design.Fig. 1 lists the schematic cross-section of several frequently seen light conducting plate structure.
As shown in a, b, c, d, e, f of Fig. 1, the structure of current light guide plate, mainly based on continuous print zigzag and irregular curve shape striped, arranges the interval of a section very little between small part product adjacent stripes.
The V-CUT structure of conventional light guiding plate, not easily meets on the one hand the requirement that existing high brightness and luminance uniformity are greater than 90%; On the other hand, in process of production, film material and the mutual rubbing contact of light guide plate easily cause and scratch and destroy V-CUT structure, affect picture effect, cause the fraction defective of product to increase.
Utility model content
The utility model, for solving the deficiencies in the prior art, provides a kind of brightness high and brightness uniformity, the light guide plate for the terminal electronic such as colour screen handset, flat board product of picture good visual effect.
The technical scheme that the utility model provides is:
A kind of light guide plate, comprises incidence surface and bottom surface and the exiting surface relative with this bottom surface, described exiting surface is arranged protruding arc strip tape, the parallel and each arc strip interband of adjacent arc strip tape every distance equal; With the straight line residing for described arc strip tape for benchmark, be incidence surface with a side of the light guide plate of described linear vertical; Described bottom surface is dot surface.
Preferably, the arc of described arc strip tape is a part for standard round.
Preferably, the width of described arc strip tape is A, is highly B, two arc strip interbands every distance be C, wherein A is 20 to 40 microns, and B is 2 to 4 microns, and C is 50 to 70 microns.
Preferably, the material of described light guide plate is good fluidity, is convenient to the resin of injection mo(u)lding.
The beneficial effects of the utility model:
The utility model by reasonably to arrange the width of arc strip tape and height and two arc strip interbands every distance, make light guide plate luminance of the present utility model improve and brightness is more even, adopt resin material good fluidity, simultaneously the utility model does not have horn structure, effectively can slow down light guide plate and optical film material because of the scuffing caused that rubs.
Accompanying drawing explanation
A and b of Fig. 1 be the band wedge angle of existing light guide plate V ?CUT structure; C and d be the interval-zone wedge angle of existing light guide plate V ?CUT structure, e and f is existing arcuation light conducting plate structure;
Fig. 2 is the structural representation of light guide plate of the present utility model;
Fig. 3 is the stereographic map of light guide plate of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the exiting surface of the light guide plate of prior art be mainly V ?CUT structure, exiting surface have continuous print horn structure (a in Fig. 1 and b) or spaced horn structure (a in Fig. 2 and b), such structure easily scratches the film material contacted with light guide plate.The light guide plate of prior art is as shown in e and f of Fig. 1 in addition, for the exiting surface with arc list structure, because two arcuate structures link together, easily because mobility is not good and heat radiation inequality causes product deformity time shaping, finally affect light guide plate optical property.
As shown in Figure 2, the utility model provides a kind of brightness high visual effect to be used on the light guide plate of the terminal electronic such as colour screen handset, flat board product, comprises arc strip tape 1, exiting surface 2, bottom surface 3 and incidence surface 4.
Described exiting surface 2 is arranged protruding arc strip tape 1, adjacent arc strip tape 1 is parallel and distance that is each arc strip tape 1 interval is equal, and the arc of described arc strip tape 1 is a part for standard round.Described arc strip tape 1 is for controlling light direction.With the straight line residing for described arc strip tape 1 for benchmark, be incidence surface 4 with a side of the light guide plate of described linear vertical, the outside of described incidence surface 4 by LED lamp source 5 for light guide plate provides light source.Described bottom surface 3 is the dot surface for diffused light source, and described bottom surface 3 is relative with described incidence surface 4.
The part that single arc strip tape 1 of the present utility model connects with exiting surface 2 is the width A of arc, wherein the arc exposed portion of arc strip tape 1 is no more than the standard radius of a circle residing for arc, the height of the arc exposed portion of arc strip tape 1 is B, two arc strip interbands every distance be C, wherein A is 20 to 40 microns, B is 2 to 4 microns, and C is 50 to 70 microns.
The material of described light guide plate is good fluidity, is convenient to the resin of injection mo(u)lding, and when making, direct integral molded plastic is shaping.
The utility model, by reasonably arranging arc strip tape 1 and arranging its size, improves the ratio of light injection on the one hand, namely improves light utilization, thus improves the brightness of backlight module; On the other hand, adopt the list structure of standard circular arc, be beneficial to the radiation direction making injection more even, be conducive to the brightness and the uniformity coefficient that promote the whole guide-lighting module of backlight.
