Abstract
The invention discloses a prism structure MS light guide plate comprising a light incident surface and a light emergent surface. The light guide plate is made of MS plastics. A prism structure is arranged on the light emergent surface. The prism structure is provided with multiple bulges which are arranged in parallel with arc-shaped cross sections. A V-shaped groove is formed between the two adjacent bulges. The depth D of the groove is 85-115 microns, and the width W is 325-395 microns. The R angular dimension of each bulge is 203-227 degrees. Brightness of the light emergent surface is high, uniformity and visibility are excellent and water absorption of the light guide plate is low.
Description
Technical field
The present invention relates to a kind of light guide plate, especially relate to a kind of prism structure MS light guide plate.
Background technology
On raising light guide plate exiting surface transmittance, those skilled in the art have made large quantity research, and such as publication number is the patent of CN104416739A (name is called light guide plate and preparation method thereof) and CN102661572A (name is called prismatic light guide plate and corresponding backlight module).Research finds, such light guide plate exiting surface transmittance is excellent all not at present.
Summary of the invention
Object of the present invention is exactly to solve the problem, and provides a kind of prism structure MS light guide plate of transmittance excellence.
To achieve these goals, the present invention adopts following technical scheme: prism structure MS light guide plate, comprise incidence surface and exiting surface, described light guide plate is made up of MS plastics, described exiting surface arranges prism structure, described prism structure has some that be arranged in parallel, that cross section is curved projections, forms V-groove between two adjacent projections; The degree of depth D of described groove is 85-115 μm, and width W is 325-395 μm, and the R angle value of described projection is 203-227 degree.
Preferably, the degree of depth D of described groove is 110 μm, and width W is 380 μm, and the R angle value of described projection is 215 degree.
Preferably, described projection cross section semicircular in shape.
Preferably, described incidence surface arranges the high reflection layer structure become by printing net-point Plate making printing.
Compared with prior art, the present invention has following beneficial effect: exiting surface brightness of the present invention is high, and homogeneity and visibility are all excellent, and light guide plate water-intake rate is low.
Accompanying drawing explanation
Fig. 1 is prism structure MS light guide plate partial sectional view in embodiment.
