Description
Technical field
The present invention relates to the dispersive propagation field of geometric optics, more particularly, to the technical field of light guide plate.
Background technology
Now light guide plate in the art is used among various displays, such as LED flat lamp, FPD and the backlight module of television set, light guide plate typically uses plastic plate or piece, enter side or surrounding that luminous point is arranged on light guide plate, light source is reflected and scattered by sags and crests, light source is set to become soft uniform, tradition is made by way of laser dotting or ink silk screen printing on smooth base material, various sizes of product needed is processed according to different layout designs, requirement to producing is strict, operation is various, high processing costs, production cycle is long, easy batch type occurs guide-lighting uneven, the low bad products of light efficiency.
The content of the invention
The present invention provides a kind of light guide plate in prismatic surface ball adding point face, and not only operation is few, and qualification rate is high, with short production cycle, and need not be directed to specific dimensions, and dispersive propagation is uniform, can't see out luminous point, and light efficiency is strong.
To solve the above problems, the present invention is adopted the following technical scheme that：Described light guide plate is made up of two kinds of different concavo-convex light guiding surfaces, the one side of light guide plate is using the micro- folding light guiding surface of V-type, another side is using hemispherical point type light guiding surface, the micro- folding light guiding surface of V-type is uniformly placed with triangle light-guiding pillar 1, described triangle light-guiding pillar 1 is in isosceles triangular prism shape, every the bottom of triangle light-guiding pillar 1 is connected, two the incline of triangle light-guiding pillar 1 constitutes a V-arrangement angle a, described hemispherical point type light guiding surface is evenly distributed with hemispherical concave point 2, and each hemispherical concave point 2 is outer from circle.
The height of described triangle light-guiding pillar 1 is 0.05~0.9mm, wheelbase L length between the symmetry axis of triangle light-guiding pillar 1 is 0.05~0.9mm, the angle of described V-arrangement angle a is 10 °~120 °, the described a diameter of 0.05~5mm of hemispherical concave point 2, the distance between each hemispherical concave point 2 is 0.05~2mm, the depth of described hemispherical concave point is 0.05~0.9 mm, and the plate body thickness of the light guide plate is 0.5~6mm.
Among geometric optics, optical critical dimensions depend primarily on the shape of propagation medium, size, distance, just along propagation medium shape forwards, backwards left and right up and down all directions propagate, according to the present invention using micro- folding light guiding surface and the hemispherical point type light guiding surface of V-type, with reference to above-mentioned size parameter, make light dispersive propagation uniform, can't see out luminous point, light efficiency is strong, and the structure can be produced using the method for extrusion forming, the mode of laser dotting or ink silk screen printing without the later stage makes, so can arbitrarily be cut according to the demand of product, reduce production process, improve qualification rate high, shorten the production cycle.
Brief description of the drawings
Fig. 1 is cross-sectional schematic of the invention.
Fig. 2 is structural representation of the invention.
Specific embodiment
The present invention is described in detail with optimal embodiment below.
As shown in Figure 1-2, described light guide plate is made up of two kinds of different concavo-convex light guiding surfaces, the one side of light guide plate is using the micro- folding light guiding surface of V-type, another side is using hemispherical point type light guiding surface, the micro- folding light guiding surface of V-type is uniformly placed with triangle light-guiding pillar 1, described triangle light-guiding pillar 1 is in isosceles triangular prism shape, every the bottom of triangle light-guiding pillar 1 is connected, two the incline of triangle light-guiding pillar 1 constitutes a V-arrangement angle a, described hemispherical point type light guiding surface is evenly distributed with hemispherical concave point 2, and each hemispherical concave point 2 is outer from circle.
The height of described triangle light-guiding pillar 1 is 0.05~0.9mm, wheelbase L length between the symmetry axis of triangle light-guiding pillar 1 is 0.05~0.9mm, the angle of described V-arrangement angle a is 10 °~120 °, the described a diameter of 0.05~5mm of hemispherical concave point 2, the distance between each hemispherical concave point 2 is 0.05~2mm, the depth of described hemispherical concave point is 0.05~0.9 mm, and the plate body thickness of the light guide plate is 0.5~6mm.
Among geometric optics, optical critical dimensions depend primarily on the shape of propagation medium, size, distance, just along propagation medium shape forwards, backwards left and right up and down all directions propagate, micro- folding light guiding surface and the hemispherical point type light guiding surface of use V-type of the invention, with reference to above-mentioned size parameter, make light dispersive propagation uniform, can't see out luminous point, light efficiency is strong, and the structure can be produced using the method for extrusion forming, the mode of laser dotting or ink silk screen printing without the later stage makes, so can arbitrarily be cut according to the demand of product, reduce production process, improve qualification rate high, shorten the production cycle.
Finally it should be noted that：Obviously, above-described embodiment is only intended to clearly illustrate example of the present invention, and not to the restriction of implementation method.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.There is no need and unable to be exhaustive to all of implementation method.And the obvious change thus amplified out or among changing still in protection scope of the present invention.
