Description

A kind of parabolic cylinder adds the light guide plate of all points

Technical field

This utility model is related to the dispersive propagation field of geometric optics, especially relates to the technical field of light guide plate.

Background technology

Now light guide plate in the art is used among various display, such as LED flat lamp, flat pannel display and television set Backlight module, light guide plate typically adopt plastic plate or piece, enter side or the surrounding that luminous point is arranged on light guide plate, by concavo-convex Point is reflected to light source and is scattered, make light source become soft uniformly, tradition be on smooth base material by laser dotting or The mode of ink silk screen printing makes, and processes various sizes of product needed according to different layout designs, strict to the requirement producing, Operation is various, and high processing costs, long the production cycle, easy batch type leaded light and disperse uneven, loss brightness.

Content of the invention

This utility model provides a kind of parabolic cylinder to add the light guide plate of all points, and not only operation is few, and qualification rate is high, the production cycle Short, cost is lower, and need not be for specific dimensions it is easy to implement, and dispersive propagation uniformly, be can't see out luminous point, made light Softer and there is higher light guide effect.

For solving the above problems, this utility model adopts the following technical scheme that：The one side of described light guide plate 1 is provided with a plurality of Tongue light-guiding pillar 2, described tongue light-guiding pillar 2 is in parabolic column, and the height H of every tongue light-guiding pillar 2 is 0.05～1.5mm, Parabola opening L1 width 0.05～2mm, the string radius of every tongue light-guiding pillar 2 is 0.05～1.5mm, described light guide plate 1 Another side is provided with multiple semi-round balls or the salient point 3 spherical less than semicircle, and described multiple salient points 3 are uniformly covered with another in light guide plate 1 Simultaneously go up, the diameter D of salient point 3 is 0.05～5mm, and the distance between each salient point 3 L2, is 0.05～2mm, the height of salient point 3 Degree E is 0.05～0.9mm, and each described salient point 3 is in the same size, and the integral thickness C of described light guide plate 1 is 0.5～6mm.

Among geometric optics, optical critical dimensions depend primarily on the shape of propagation medium, size, distance, just Along shape upper and lower all directions propagation about forwards, backwards of propagation medium, thrown according to of the present utility model employing of diffraction theory Thing cylinder and sphere, in conjunction with above-mentioned size parameter, and this structure can adopt the method for extrusion molding to produce, without the later stage The mode of laser dotting or ink silk screen printing makes it is possible to arbitrarily be cut according to the demand of product, not only operation is few, qualification rate Height, with short production cycle, cost is lower, and need not be for specific dimensions it is easy to implement, and dispersive propagation uniformly, be can't see out Luminous point, makes light softer and has higher light guide effect.

Specific embodiment

With optimal embodiment, this utility model is described in detail below.

As Figure 1-3, the one side of described light guide plate 1 is provided with a plurality of tongue light-guiding pillar 2, described tongue light-guiding pillar 2 In parabolic column, the height H of every tongue light-guiding pillar 2 is 0.05～1.5mm, parabola opening L1 width 0.05～2mm, every The string radius of tongue light-guiding pillar 2 is 0.05～1.5mm, and described light guide plate 1 another side is provided with multiple semi-round balls or is less than semicircle Spherical salient point 3, described multiple salient points 3 are uniformly covered with light guide plate 1 another side, and the diameter D of salient point 3 is 0.05～5mm , the distance between each salient point 3 L2, is 0.05～2mm, and the height E of salient point 3 is 0.05～0.9mm, described light guide plate 1 Integral thickness C be 0.5～6mm.

Among geometric optics, optical critical dimensions depend primarily on the shape of propagation medium, size, distance, just Along the shape of propagation medium, up and down all directions are propagated for left and right forwards, backwards, according to diffraction theory of the present utility model using adopting With using parabolic cylinder and sphere, in conjunction with above-mentioned size parameter, and this structure can adopt the method for extrusion molding to produce, no The laser dotting in later stage or the mode of ink silk screen printing is needed to make it is possible to arbitrarily be cut according to the demand of product, not only operation Few, qualification rate is high, and with short production cycle, cost is lower, and need not be for specific dimensions it is easy to implement, and dispersive propagation is uniform, Can't see out luminous point, make light softer and there is higher light guide effect.

Finally it should be noted that：Obviously, above-described embodiment is only intended to clearly illustrate this utility model example, And the not restriction to embodiment.For those of ordinary skill in the field, also may be used on the basis of the above description To make other changes in different forms.There is no need to be exhaustive to all of embodiment.And thus The obvious change amplified out or change among still in protection domain of the present utility model.
