Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection scope of the present invention.
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail.
Embodiment one
As shown in Figure 2, Figure 3 and Figure 4, a kind of electronic equipment, comprises display screen 7, and this display screen can be LCDs; Also be provided with refractive body 6 below display screen 7, be also provided with the light source 3 providing backlight in electronic equipment, light source 3 generally adopts LED simultaneously.Described refractive body 6 comprises reflective surface 61, described reflective surface 61 is relative with described display screen 7 lower surface, described reflective surface 61 is attached with the first reflective membrane 5, refractive body 6 and on the first reflective membrane 5 for replacing backlight assembly of the prior art and providing backlight for display screen 7.
In this example, between described first reflective membrane 5 and described display screen 7, form cavity 12; Described light source 3 is arranged at the side of described cavity 12.This cavity 12 adopts air to be the propagation medium of light, alleviates the weight of equipment, solves prior art simultaneously and adopts the transparent materials such as organic glass to be that the propagation medium of light requires high shortcoming to material light transmission.
In this example, described reflective surface 61 comprises extended surface 10, and extended surface 10 is just provided at that a part of reflective surface 61 that display screen 7 lower edge exceeds display screen 7 lower surface; In this situation, described light source 3 is arranged at above extended surface 10, as shown in Figure 3.The advantage of this structure light source 3 to be located at the side of display screen 7, can reduce the distance formed between the first reflective membrane 5 and described display screen 7, reduce the volume of equipment further.Certain light source 3 can be arranged at any position in electronic equipment, as long as it is just passable that its light can be irradiated to the first reflective membrane 5, solve prior art light source and need be fixed at the problem that organic glass etc. plays the transparent material side of guide-lighting effect, make structural design more flexible.Light source 3 can be fixed on the circuit board 2, and circuit board 2 does not represent in Fig. 2 and Fig. 3, please refer to Fig. 5, directly by circuit board 2 powered operation, also can be fixed on back casing 1 or procapsid 9, then by wire powered operation.
This realizes the reflection of light better, and described reflective surface 61 to reduce to away from light source 3 side near light source 3 side gradually with the spacing of described display screen 7.Described reflective surface 61 can be plane, forms a dip plane; Described reflective surface 61 also can be curved surface, and be the curved surface of concave or convex, the distance between reflective surface 61 and described display screen 7 increases gradually from curved edges to center of surface; Advantageously in the reflection of light.
In addition, the first reflective membrane 5 is provided with point-like or wire diffuse reflection projection or depression.Its material can adopt metal forming as aluminium foil, also can adopt plastic sheeting, and Plastic film surface can also be adopted to plate reflective membrane, can also be papery film, but preferably at papery film plated surface reflective membrane.The effect of the first reflective membrane 5 is that the light reflection of light source 3 (also can be refraction, scattering, transmission) is formed backlight to display screen 7 back side.Point-like or the wire diffuse reflection projection on the global shape of the first reflective membrane 5 and surface or cave in should according to the fundamental reflection of optics (also can be reflect, scattering, transmission) principle makes, can ensure as display screen 7 provides suitable backlight to be as the criterion, can be completed by Theoretical Design Binding experiment, be that those of ordinary skill in the art just can complete smoothly without the need to creative work person, no longer describe in detail.
First reflective membrane 5 is fixed on the reflective surface 61 of refractive body 6, generally adopts bonding method.By this kind of mode, eliminate backlight modular construction, make the structure of equipment more simple, assemble simpler and easy, and cost is lower, existing screen intensity can be reached completely simultaneously, meet user and use.
In addition, the first reflective membrane 5 can also be sprayed at the reflective membrane that reflective surface 61 is formed; This scheme is generally direct sprays reflectorized material on reflective surface 61, and reflectorized material can be fluorescent paint, aluminium paint etc.The program normally directly produces point-like or wire diffuse reflection projection or depression on reflective surface 61, then carries out spraying reflective membrane.
In addition, the first described reflective membrane 5 can also be the reflective membrane of direct plating on reflective surface 61; This scheme is Plastic film surface plating reflective membrane normally, also can be at papery film plated surface reflective membrane.
In order to prevent light source 3 light from appearing apparatus casing, this equipment also comprises shadow shield 13, for stopping that light source 3 light irradiates in housing, or, directly adopt lighttight material to make housing.An easy mode is that described shadow shield directly uses circuit board 2, and light source 3 is located on circuit board 2, and structure is simple.
In addition, in order to more effectively utilize the shadow shield 13 described in light source 3 to be attached with the second reflective membrane 11 near light source 3 one side.Second reflective membrane 11 is fixed on below shadow shield 13, the general mode adopting stickup or spraying.Second reflective membrane 11 is provided with point-like or wire diffuse reflection projection or depression.Its material can adopt metal forming as aluminium foil, also can adopt plastic sheeting, and Plastic film surface can also be adopted to plate reflective membrane, can also be papery film, but preferably at papery film plated surface reflective membrane.The effect of the second reflective membrane 11 is on the first reflective membrane 5 by the light reflection of light source 3 (also can be refraction, scattering, transmission).
In addition, be integrated on the housing that the refractive body 6 in this example is fixed on described equipment or with housing.Concrete fixed form is known for those of ordinary skill in the art, no longer describes.
The structure of this example, the housing of equipment comprises back casing 1 and procapsid 9, and display screen 7 is located at procapsid 9 and is windowed inner side, place, is provided with circuit board 2 between back casing 1 and procapsid 9 in space.
Embodiment two
As shown in figs. 5 and 6, a kind of electronic equipment, with embodiment one unlike, on each scheme basis of embodiment one, described display screen 7 lower surface also posts light guiding film 4.Light guiding film 4 can adopt semi-transparent film.The material of light guiding film 4 can be plastics or paper.The light of reflection on the first reflective membrane 5 can also carry out weakening by this light guiding film 4, equalization, softening etc., make the light of display screen 7 more soft clear.
The above; be only the present invention's preferably embodiment, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
