Abstract
The utility model relates to the technical field of liquid crystal display, in particular to a novel reflective sheet. The novel reflective sheet comprises a concaved reflective sheet body, a diffusion plate arranged at an opening of the reflective sheet body, and a light source arranged at the bottom of the reflective sheet body. The reflective sheet body comprises a side reflector on the side face and a bottom reflector at the bottom. The normal angles of the side reflector are multiple in number. By means of the structure, when light rays emitted by the light source are reflected through the side reflector, due to the fact that the reflecting angles of the side reflector are multiple in number, the light rays can be better gathered or diffused, the problem of darkening or a bright edge of a backlight module is effectively solved, the display picture of a display is more uniform, and the better visual perception is provided for a user.
Description
Technical field
The utility model relates to technical field of liquid crystal display, refers more particularly to a kind of new type reflection sheet.
Background technology
At present, in TV industry and display industry, adopt liquid crystal display, simultaneously, with low-carbon (LC), the energy-conservation idea popular feeling that deepens continuously, straight-down negative LED's is backlight prevailing more, and the market demand is constantly soaring.As shown in Figure 1, at present in direct-light type LED backlight design, in the many employings of reflector plate design, establishing surrounding inclined-plane reflector plate mode designs, but all there is the flaw of same a kind of subjective picture in this type of design in different size, different straight-down negative LED scheme, that is: there is a circle blanking bar in module surrounding, in the edge of picture, presents the phenomenon of bright border simultaneously.
utility model content
The purpose of this utility model is for the problems referred to above, and a kind of new type reflection sheet is provided, and makes display display frame more even, optimizes the subjective picture of TV or display, gives the more good visual experience of user.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of new type reflection sheet, comprise spill reflector plate, be located at the diffuser plate of reflector plate opening part and be located at the light source of reflector plate bottom, it is characterized in that: described reflecting plate comprises the lateral reflection plate of side and the end reflecting plate of bottom, and the normal angle of described lateral reflection plate is multiple.
Further, described lateral reflection plate can be outside convex surface or the convex surface that is comprised of polylith different angles plane, can be also inside concave curved surface or the concave surface that is comprised of multistage different angles plane.
Further, described light source is multiple LED lamps, and described LED lamp forms by light emitting diode and to coming from the lens that the light of this light emitting diode spreads.
The utility model adopts said structure; the light that light source sends is by lateral reflection plate reflex time; because the reflection angle of lateral reflection plate is multiple; make light more gather or to spread; effectively solve the dark change of backlight module or bright border problem; display display frame is more even, gives the more good visual experience of user.
Accompanying drawing explanation
Fig. 1 is the utility model partial cross section schematic diagram.
Fig. 2 is traditional reflective plate light effects schematic diagram.
Fig. 3 is the utility model light effects schematic diagram.
Fig. 4 is the utility model the second example ray of light effect schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail, but not as to restriction of the present utility model.
As Fig. 1, Fig. 3, shown in Fig. 4, a kind of new type reflection sheet, comprise the reflector plate 1 of spill, be located at the diffuser plate 2 of reflector plate 1 opening part, and be located at the light source 3 of reflector plate 1 bottom, described reflecting plate 1 comprises the lateral reflection plate 11 of side and the end reflecting plate 12 of bottom, the normal angle of described lateral reflection plate 11 is multiple, be that lateral reflection plate 11 can be outside convex surface or the convex surface that is comprised of polylith different angles plane, also can be inside concave curved surface or the concave surface that formed by multistage different angles plane, described light source 3 is multiple LED lamps, described LED lamp forms by light emitting diode and to coming from the lens that the light of this light emitting diode spreads.
As shown in Figure 2, traditional reflector plate 1 adopts the mode on surrounding inclined-plane to reflect light, and the normal direction of all light 5 on reflecting surface is consistent, and light 5 cannot scatter in screen-picture edge after reflection, forms module picture blanking bar or bright border.
As shown in Figure 3, lateral reflection plate 11 is concave curvatures, compared with Fig. 2 tradition inclined-plane lateral reflection plate 11, from light source 3, penetrate same light 5, the light area L2 forming on diffuser plate 2 through concave curvatures is less than the light area L1 forming at diffuser plate through inclined-plane, solves the problem with lateral reflection plate 11 blanking bars of traditional ramp type.
As shown in Figure 4, lateral reflection plate 11 is the multistage convex surface of three sections of different angles inclined-plane compositions, compared with Fig. 2 tradition inclined-plane lateral reflection plate 11, from light source, penetrate same light 5, the light area L3 forming on diffuser plate 2 through concave curvatures is larger than the light area L1 forming at diffuser plate through inclined-plane, solves the problem with lateral reflection plate 11 bright bands of traditional ramp type.
Certainly, lateral reflection face 11 can be also the concave combination of face, inclined-plane and curved surface of convex surface, multistage, and the slope on the curvature of curved surface and multistage inclined-plane can be also any variation, is included in declared range of the present utility model, does not repeat them here.
The utility model adopts said structure; the light that light source sends is by lateral reflection plate reflex time; because the reflection angle of lateral reflection plate is multiple; make light more gather or to spread; effectively solve the dark change of backlight module or bright border problem; display display frame is more even, gives the more good visual experience of user.
Below the utility model is described in detail, but apparent, those skilled in the art can carry out various changes and improvements, and does not deviate from the scope of the present utility model that appended claims limits.
