Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in instructions of the present utility model herein just in order to describe specific embodiment, is not intended to be restriction the utility model.Term as used herein " and/or " comprise arbitrary and all combinations of one or more relevant Listed Items.
Referring to Fig. 1, Fig. 2, is the curved-surface display device 100 in an embodiment.This curved-surface display device 100 comprises display module 110 and light conduction plate 120 thereof.
Refer to Fig. 1, display module 110 can be liquid crystal display module, comprises the back light unit 111, infrabasal plate 113, liquid crystal layer 114 and the upper substrate 115 that stack gradually.Infrabasal plate 113 and the upper substrate 115 of display module 110 are writing board shape.In other embodiments, showing module also can be organic light-emitting diode display module etc.
See also Fig. 2, light conduction plate 120 has inner face 121 and an outer face 122, and inner face 121 and outer face 122 are oppositely arranged.Inner face 121 is plane, for fitting with display module 110.Particularly, the inner face 121 of light conduction plate 120 is attached at the surface of upper substrate 115.Outer face 122 is concave curved surface.
Light conduction plate 120 also has multiple spaced light-conductive pipeline 123, and light-conductive pipeline 123 is made up of high transparency optical material.Be filled with resin 124 between multiple light-conductive pipeline 123, resin 124 is for the relative space position of fixing light-conductive pipeline 123.
Each light-conductive pipeline 123 comprise the first end face 1231 and the second end face 1232, first end face 1231 concordant with inner face 121, the light that sends of display module 110 injects light-conductive pipeline 123 from inner face 121.Second end face 1232 of each light-conductive pipeline 123 is concordant with outer face 122, the refractive index of light-conductive pipeline 123 is greater than the refractive index of the medium outside light-conductive pipeline 123, thus the light making inner face 121 enter the first end face 1231 is totally reflected in light-conductive pipeline 123, finally penetrated by the second end face 1232 of light-conductive pipeline 123.
The diameter of each light-conductive pipeline 123 is 8 μm ~ 20 μm, much smaller than the size of the pixel of display module 110.In order to cover the lighttight frame at display module 110 edge, light-conductive pipeline 123 is obliquely installed, to improve visual experience.Because the light penetrated from display module 110 can only penetrate from the second end face 1232 of light-conductive pipeline 123, new light-emitting area is formed in the outer face 122 of light conduction plate 120 during light injection, so human eye observation to be new light-emitting area, and cannot observe display module 110 edge lighttight frame.Certainly, in other embodiments, light-conductive pipeline 123 can also be bending.
Above-mentioned display device 100 and light conduction plate 120 thereof at least have the following advantages:
The light sent from the display module 110 of plane enters light-conductive pipeline 123 from inner face 121 via the first end face 1231, and be totally reflected in light-conductive pipeline 123, and then penetrated by the second end face 1232 of light-conductive pipeline 123, thus the light that the display module 110 of plane sends is conducted to outer face 122 again send, form a new light-emitting area.Outer face 122 is concave curved surfaces, thus human eye actual observation to the space arrangement of light emitting pixel of display module 110 be also a concave curved surface, thus realize curved-surface display, improve display effect.The utility model without the need to the glass substrate of flat-panel screens being bent to form curved surface by metal die, so can not the problems such as breaking glass panel be caused.
Referring to Fig. 3, is the curved-surface display device 200 in another embodiment, and this curved-surface display device 200 comprises display module 210 and light conduction plate 120.Display module 210 comprises the back light unit 211, infrabasal plate 212 and the liquid crystal layer 213 that stack gradually, and liquid crystal layer 213, as the upper substrate of display module 210, is sandwiched between infrabasal plate 212 and light conduction plate 120 by light conduction plate 120.Certainly, in other embodiments, showing module 210 can also be organic light-emitting diode display module etc.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
