Embodiment
Below in conjunction with accompanying drawing and multiple embodiment, the contact panel that the technical program provides is described in further detail.
Refer to Fig. 1, the light conductor 100 that the embodiment of the present invention provides mainly comprises one first sequentially stacked colloid layer 20, one second colloid layer 30 and one the 3rd colloid layer 40.This first colloid layer 20, second colloid layer 30 and the 3rd colloid layer 40 sequentially solidify to form integrative-structure respectively.
This first colloid layer 20 and the second colloid layer 30 select the one in epoxy resin, polymethyl acrylate (PMMA) and silica gel.The interface that this first colloid layer 20 is connected with this second colloid layer 30 has the concaveconvex structure 22 of multiple diffusion light.This first colloid layer 20 and the second colloid layer 30 layering are formed and first Post RDBMS, to form this interface.This concaveconvex structure 22 can form (embodiment of the method see following) by the method for the method of mould transfer printing or particle doping.Especially, when this first colloid layer 20 and the second colloid layer 30 select identical material, and when forming concaveconvex structure 22 with mould printing transferring method, preferably depth dimensions is larger for this concaveconvex structure 22, so when the second colloid layer 30 is coated on this concaveconvex structure 22, the recess of this concaveconvex structure 22 does not fill up the material of this second colloid layer 30 completely, therefore finally can form the concaveconvex structure of porous between this first colloid layer 20 and the second colloid layer 30.Be appreciated that, when the interface that this first colloid layer 20 is connected with the second colloid layer 30 is different materials, this relief structured interface, as whole existence, can not disappear because of the covering of the second colloid layer 30.
The material selection UV glue of the 3rd colloid layer 40.3rd colloid layer 40 is formed with multiple prism 42 deviating from the optically focused of this second colloid layer 30.
This light conductor 100 can also comprise the diaphragm 10 and a upper protective film 50 with demoulding.This lower diaphragm 10 is attached at the bottom surface that this first colloid layer 20 deviates from this second colloid layer 30, and this upper protective film 50 is covered on the prism 42 of the 3rd colloid layer 40.This lower diaphragm 10, upper protective film 50 surface are plane.This lower diaphragm 10, upper protective film 50 can the structure of protecting colloid layer not contaminated or destroy.When light conductor 100 uses, this lower diaphragm 10, upper protective film 50 can be torn off.Owing to having demoulding, this lower diaphragm 10, upper protective film 50 can not destroy those colloid layers.This lower diaphragm 10, upper protective film 50 can be selected the material different from those colloid layers, and can be flexibility.This lower diaphragm 10, upper protective film 50 can be reused.
This light conductor 100 can be used in backlight module, and it has optically focused and diffusion light two kinds of functions concurrently.Light first can be assembled through prism 42 and spread evenly through concaveconvex structure 22.This light conductor integrative-structure makes light conductor weight reduce, and cost reduces, and light can directly be propagated in light conductor, and light loss is reduced.
This light conductor 100 can obtain according to following method.First, the first colloid layer 20 of the printing opacity that formation one is uncured.Then, form the concaveconvex structure 22 of diffusion light in the surface of this first colloid layer 20, then solidify the first colloid layer 20 that this has concaveconvex structure 22.Wherein, this concaveconvex structure 22 can use the method for mould transfer printing to be formed, and now this concaveconvex structure 22 is integrated with this first colloid layer 20.In addition, directly can be sprinkled into particle on the surface of this first colloid layer 20, to form concaveconvex structure on the surface of this first colloid layer 20; Or on the concaveconvex structure of mould transfer printing, be sprinkled into particle again, to form relief structured interface better between this first colloid layer 20 and second colloid layer 30.This particle has optical property that is transparent, high index of refraction.
Secondly, on this concaveconvex structure 22, the second colloid layer 30 of the printing opacity that coating one is uncured, then solidifies this second colloid layer 30.After the solidification of this second colloid layer 30, namely there is certain degree of hardness, so when the prism 42 of formation the 3rd colloid layer 40, can play a supporting role.This second colloid layer 30 needs suitable thickness, and this thickness is advisable to be greater than the first colloid layer 20, can play a supporting role and not destroy concaveconvex structure 22.
Next, apply the 3rd colloid layer 40 of a printing opacity in the surface of this second colloid layer 30, then, form multiple prism 42 deviating from the optically focused of this second colloid layer 30 in the surface of the 3rd colloid layer 40, then solidify the 3rd colloid layer 40 that this has prism 42.Wherein, the method for mould transfer printing can be used to form those prisms 42.
Especially, this first colloid layer 20 can directly first be formed on this lower diaphragm 10, and namely this lower diaphragm 10 first can serve as base material, tears off when light conductor 100 uses again.After 3rd colloid layer 40 solidifies, this upper protective film 50 can be covered on prism 42, tears off when light conductor 100 uses again.
3rd colloid layer 40 can directly use UV photocuring.This first colloid layer 20 and the second colloid layer 30 can according to the general curing solidifications of used material, such as electron beam radiation cured, heat curing etc.
Be understandable that, for the person of ordinary skill of the art, other various corresponding change and distortion can be made by technical conceive according to the present invention, and all these change the protection domain that all should belong to the claims in the present invention with distortion.
