Abstract
The invention discloses a light guide plate with high luminous efficiency and uniform brightness and a manufacturing method thereof. The light guide plate comprises a body, the upper surface of the body is provided with light guide grids, and the density of the light guide grids increases gradually from one end to the other end of the body. According to the light guide plate with high luminous efficiency and uniform brightness and the manufacturing method thereof, the light guide grids carved on the body can diffuse light emitted by a light source; the intersections of the light guide grids are provided with light guide grooves, so light can be diffused better; and as the density of the light guide grids increases gradually from one end to the other end of the body, light can be diffused more uniformly.
Description
Technical field
The invention belongs to light guide plate field, more specifically, particularly relate to the light guide plate of a kind of specular removal, brightness uniformity.
Meanwhile, the invention still further relates to the manufacture method of the light guide plate of a kind of specular removal, brightness uniformity.
Background technology
Light guide plate is the acrylic/PC sheet material utilizing optical grade, then by the high-tech with high reflectance and not extinction
Skill material, the acryl plates bottom surface UV screen printing technology in optical grade stamps light guiding points.Utilize optical grade acrylic board
Material draws the light issued from the lamp stop on optical grade acryl plates surface, when light is mapped to each light guiding points, reflection
Light can spread toward all angles, then destroys conditioned reflex and is penetrated by light guide plate front.By various densitys, not of uniform size leading
Luminous point, can make light guide plate uniformly light-emitting.The purposes of reflector plate is that the luminous reflectance exposed bottom surface returns in light guide plate, is used for improving
The service efficiency of light；In the case of homalographic luminosity, luminous efficiency is high, low in energy consumption.One side micro structure array light guide plate one
As use the processing technology of extrusion molding.
About the backlight apparatus from the back side illuminaton light of display panels or signboard etc., it is known to light source is configured to
Planar also forms the directly-below type of face uniformly light-emitting by diffusing panel etc. and line source is configured at being referred to as of end face of light guide plate
The light guide plate mode of edge-light or sidelight.In recent years, more slim and light weight, energy-saving backlight apparatus are expected.As
Such backlight apparatus, light guide plate mode is attracted attention.Especially as light source, replace conventional fluorescent lamp or cold cathode
Pipe, from high brightness and longevity
Life, energy-conservation from the viewpoint of, LED(Light Emitting Diode, light emitting diode) just receive publicity.At backlight
In the light guide plate of device, make inside light guide plate diffusion member dispersion or on surface, at least one party at the back side arrange light overflow
Penetrate layer or diffusing pattern.This light guide plate makes light be injected into this light guide plate from the cold-cathode tube or LED array light source being arranged on end face
In, and make light form planar light source device to emitting side injection.
And the luminous efficiency of existing light guide plate is the most on the low side, and there is non-uniform light, bright border or dark space occur.Cause
This, the density degree and the size degree that how to arrange the light guiding points on light guide plate just can make the light efficiency effect of light guide plate reach
Good state plays and always is difficult point.
Summary of the invention

The present invention also provides for the manufacture method of the light guide plate of a kind of specular removal, brightness uniformity, comprises the steps:
S1, material prepare: select acrylic board as making material, cleaned up by acrylic board, to irregular acrylic
Plate needs polish or change, it is ensured that acrylic board flat smooth, in order to avoid because sheet material problem affects light guide effect.
Prepared by S2, pattern: drawn out on laser engraving software and import laser engraving machine by the pattern of guide-lighting grid
In, the acrylic board printout surface selected in S1 by laser engraving machine goes out corresponding pattern.
S3, sheet material post processing: sheet material after engraving will check in S2, it is desirable to pattern is smooth, recessed outside pattern-free
Groove or salient point, then by sheet material alcohol washes the wiping of passed examination.
S4, pad pasting process: the sheet material cleaned up in S3 is placed on dustless room and dries, again at plate surface after drying
Stick reflective membrane and light-diffusing film.
Preferably, in described S2 pattern preparation process, acrylic board and laser engraving equipment are placed in dustless room,
Prevent dust impact engraving quality.
Preferably, cleaning alcohol concentration used in described S3 is 10-20%.
The technique effect of the present invention and advantage: a kind of specular removal, the light guide plate of brightness uniformity and the system thereof that the present invention provides
Making method, by carving out guide-lighting grid on body, can be spread apart by the light that light source sends, the point of intersection of guide-lighting grid sets
Have guide grooves, can more preferable diffusing light, the density of guide-lighting grid is gradually increased to the other end from one end of body, can be by
It is more uniform that light spreads.
