Description
Technical field
The present invention relates to a kind of display backlight plate.
Background technology
Car audio system commonly uses LCD and shows, uniform LCD backlight is the enjoyment on a kind of sense organ for consumers, is also the requirement of car enterprise.And industry is interior by space, structure influence at present, mainly shines the methods such as line by increase LED quantity and light guide plate and meet uniform backlighting requirements.And use the mode increasing LED quantity, as used the method such as the uniform LED in both sides or unilateral intensive layout LED, although can preferably solve LCD backlight homogeneity question, but cost is the highest.And the method using a small amount of LED+ backlight to shine line, owing to current light analogue technique is the most ripe, and there is no complete theoretical system support, can only test by constantly shining line, be extremely difficult to perfect condition, and the R&D cycle is long, die cost is high.
Summary of the invention
In order to solve the problems referred to above that existing LCD backlight exists, saving development cost, the present invention provides the design of a kind of wedge shape display backlight plate.
A kind of display backlight plate, the backlight used including backlight and cooperation backlight, described backlight is transparent clapboard, including shady face, exiting surface and incidence surface, described incidence surface is perpendicular to exiting surface, backlight is arranged at incidence surface, it is additionally provided with and transparent enters light component, enter light component be a cross section be the triangular prism of isosceles right triangle, first right-angle surface of triangular prism is arranged with incidence surface laminating, bottom surface is provided with reflector layer, bottom surface and exiting surface angle at 45 °, second right-angle surface is parallel with exiting surface, backlight is arranged at the second right-angle surface.
Concrete, described reflector layer is reflective pad pasting or reflective sticker or reflecting coating.
More specifically, described backlight shady face is provided with diffusing reflection face.
Further, enter light component described in be integrated with backlight.
Preferably, diffusing reflection face is a matte uniformly losing line.
Preferably, diffusing reflection face is reflective pad pasting or a reflective sticker.
Preferably, diffusing reflection face is a reflective enamelled coating.
In sum, the method have the advantages that (1) is simple for structure, easily produce；(2) use unilateral illumination, LED quantity can be greatly reduced, reduce cost；(3) LED incidence point distance reflective surface is the shortest, and incident light is similar to uniform parallel rays, is reflected and forms uniform backlight effect at exiting surface after diffusing reflection.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of display backlight plate of the present invention；
Fig. 2 is the overall structure schematic diagram of display backlight plate of the present invention.
Detailed description of the invention
In order to allow those skilled in the art can be best understood from technical scheme, below the invention will be further elaborated.
As illustrated in fig. 1 and 2, present invention is disclosed a kind of display backlight plate, the backlight 2 used including backlight 1 and cooperation backlight, described backlight is transparent clapboard, including shady face 11, exiting surface 12 and incidence surface 13, backlight 2 is arranged at incidence surface.Incidence surface 13 is additionally provided with and transparent enters light component 14, enter light component 14 be a cross section be the triangular prism of isosceles right triangle, first right-angle surface of triangular prism is arranged with incidence surface laminating, and bottom surface is provided with reflector layer, and reflector layer can be realized by reflective pad pasting or reflective sticker or reflecting coating.Bottom surface and exiting surface angle at 45 °, the second right-angle surface is parallel with exiting surface, and backlight is arranged at the second right-angle surface.Enter light component to be integrated with backlight.
Light is from backlight 2(LED etc.) injection after, by being reflected into backlight at bottom surface (reflective surface) after entering the second right-angle surface of light component, owing to LED incidence point distance reflective surface is the shortest, now light is similar to a kind of parallel uniform light, parallel under the reflection of backlight injects backlight.The shady face of backlight is provided with diffusing reflection face, and light ray parallel is injected after backlight in diffusing reflection face by diffusing reflection equably.Reach the effect of even back.
Diffusing reflection face can realize by uniformly losing the method such as line, spray or silk-screen reflectorised paint, patch reflective membrane, patch reflecting piece.
The present embodiment is the more excellent embodiment of the present invention, and the part not being described in detail all uses known mature technology.It should be noted that; in the case of without departing substantially from present invention spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and deformation according to the present invention, but these change and deform the protection domain that all should belong to appended claims of the invention.
