Abstract
The utility model relates to a kind of light guide plate end face structure, comprising light guide plate end face, light guide plate end face extrudes through the contact movement of hot roller and light guide plate end face makes the temperature distortion of light guide plate end face form thickened section, described thickened section is that on light guide plate end face its thickness D, increase height H be 50-300 μm, and length L is 10-200 μm; Solve and lack for printing, the manufacturing process of hot pressing and ink-jet provides the problem of Wedge shape light conduction board; Increase light efficiency, yields is high.
Description
Technical field
The utility model belongs to electronics field, is specifically related to a kind of light guide plate end face structure.
Background technology
Light guide plate manufacturing technology is mainly divided into injection moulding, and printing, hot pressing, ink-jet four kinds, wherein only have injection moulding can manufacture the inconsistent Wedge shape light conduction board of light guide plate segment thickness by formed in mould mode, other three kinds of modes all cannot manufacture.But injection moulding production efficiency is very low, and equipment investment cost is very high, the production cost of light guide plate can not be reduced and enhance productivity.
After the light guide plate of present more than 0.5mm directly can provide this kind of clapboard when large sheet metal forming by extruder, processing of cutting is shaping, but for below 0.5mm light guide plate at present large plate extruder to manufacture this kind of clapboard yields very low.
Utility model content
The purpose of this utility model is to provide and a kind ofly increases light efficiency, light guide plate end face structure that cost is low.
The technical scheme realizing the utility model object is: a kind of light guide plate end face structure, comprising light guide plate end face, light guide plate end face extrudes through the contact movement of hot roller and light guide plate end face makes the temperature distortion of light guide plate end face form thickened section, described thickened section is that on light guide plate end face its thickness D, increase height H be 50-300 μm, and length L is 10-200 μm.
Preferred described thickened section is 1/4 semicircle or 1/4 oval or triangle.
The temperature of preferred described hot roller is 80-150 degree.
Preferred described light guide plate end face is 90 degree by the temperature of thermal deformation.
The utility model has positive effect: by thermal deformation, light guide plate end face occurs that the light efficiency that thickened section makes LED light source enter light guide plate end face increases, yields is high, decreases the dependence to external sheet material, and working (machining) efficiency is more than 3 times of common process.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is a kind of light guide plate end face structure schematic diagram;
Fig. 2 is the cut-open view of a kind of light guide plate end face structure along A-A;
1 is light guide plate end face, and 2 is thickened section
Embodiment
See Fig. 1 and Fig. 2, the utility model has a kind of light guide plate end face structure, comprising light guide plate end face 1, light guide plate end face 1 extrudes through the contact movement of hot roller and light guide plate end face 1 makes light guide plate end face 1 temperature distortion form thickened section 2, described thickened section 2 is that on light guide plate end face 1 its thickness D, increase height H be 50-300 μm, and length L is 10-200 μm.
Further described thickened section 2 is 1/4 semicircle or 1/4 oval or triangles.
The temperature of further described hot roller is 80-150 degree.
Further described light guide plate end face 1 is 90 degree by the temperature of thermal deformation.
When the roller being heated to 80-150 degree rolls along the side of light guide plate to opposite side, extruding causes light guide plate end face 1 to be heated generation deformation, light guide plate can shorten, light guide plate end face 1 forms thickened section 2, the light that LED light source is entered from the light guide plate end face 1 thickened increases, and light efficiency is improved 5%-10%.
Thus can be printing, the manufacturing process of hot pressing and ink-jet provides Wedge shape light conduction board, effectively can reduce the cost of whole backlight, promotes the brightness of whole backlight, reduces energy consumption about 20%; And the dull and stereotyped aft-loaded airfoil wedgewise plate of common below 0.5mm can be used, yields can reach more than 99%, decreases the dependence to external sheet material, and working (machining) efficiency is more than 3 times of common process.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
