Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on embodiments of the invention, those of ordinary skills belong to protection scope of the present invention not making the every other embodiment that is obtained under the creative work prerequisite.
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
Embodiment one
As Fig. 2, Fig. 3 and shown in Figure 4, a kind of electronic equipment comprises display screen 7, and this display screen can be LCDs; Display screen 7 belows also are provided with refractive body 6, also are provided with the light source 3 that provides backlight in the electronic equipment simultaneously, the light source 3 general LED lamps that adopt.The upper surface of described refractive body 6 is a reflective surface 61 through surface treatment, reflective surface 61 is used for light with light source 3 and reflexes to display screen 7 lower surfaces, described reflective surface 61 is relative with described display screen 7 lower surfaces, and the described refractive body 6 that is provided with reflective surface 61 is used to replace backlight assembly of the prior art and provides backlight for display screen 7.Removed the backlight modular construction, made that the structure of equipment is simpler, assembled simpler and easyly, and cost is lower, can reach existing screen intensity fully simultaneously, satisfies user's use.
In this example, form cavity 12 between the reflective surface 61 of described refractive body 6 and the described display screen 7; Described light source 3 is arranged at the side of described cavity 12.It is the propagation medium of light that this cavity 12 adopts air, alleviated the weight of equipment, and having solved prior art simultaneously, to adopt transparent material such as organic glass be that the propagation medium of light is to the demanding shortcoming of material light transmission.
In this example, described reflective surface 61 comprises extended surface 10, and extended surface 10 is exactly to be located at that a part of reflective surface 61 that display screen 7 lower edge exceed display screen 7 lower surfaces; Under this situation, described light source 3 is arranged at extended surface 10 tops, as shown in Figure 3.The advantage of this structure is light source 3 to be located at the side of display screen 7, can reduce the distance that forms between the reflective surface 61 of refractive body 6 and the described display screen 7, has dwindled the volume of equipment further.Certainly light source 3 can be arranged at any position in the electronic equipment, as long as it is just passable that its light can shine the reflective surface 61 of refractive body 6, solved the prior art light source and need be fixed at the problem that organic glass etc. plays the transparent material side of leaded light effect, made structural design more flexible.Light source 3 can be fixed on the circuit board 2, and circuit board 2 is not expression 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 the procapsid 9, again by the lead powered operation.
This realize reflection of light better, between described reflective surface 61 and the described display screen 7 distance near light source 3 sides to reducing gradually away from light source 3 sides.Described reflective surface 61 can be the plane, forms a dip plane; Described reflective surface 61 also can be curved surface, is the curved surface of concave or convex, and the distance between reflective surface 61 and the described display screen 7 increases from the curved edges to the center of surface gradually; Help the reflection of light more.
In addition, the reflective surface 61 of refractive body 6 is provided with point-like or wire diffuse reflection projection or depression.The material of its refractive body 6 can adopt metal such as aluminium, also can adopt plastics, preferably its surface is handled during use, and the face surface treatment adopts surface coating or surface finish to handle usually.The reflective surface 61 that makes refractive body 6 reflexes to display screen 7 back sides with the light of light source 3 and forms backlight.The point-like on the global shape of reflective surface 61 and surface or wire diffuse reflection projection or depression should be made according to the fundamental reflection principle of optics, can guarantee to be that display screen 7 provides suitable backlight being as the criterion, can finish in conjunction with experiment by Design Theory, be that those of ordinary skill in the art need not the creative work person just can finish smoothly, no longer describe in detail.
Above-mentioned, surface treatment can also be the reflectorized material that is sprayed on the reflective surface 61, reflectorized material can be fluorescent paint, aluminium paint or the like.This scheme is normally directly produced point-like or wire diffuse reflection projection or depression on reflective surface 61, spray reflective membrane again.
In order to prevent that light source 3 light from appearing apparatus casing, this equipment also comprises shadow shield 13, is used to stop light source 3 irradiate light in housing, perhaps, directly adopts lighttight material housing.An easy mode is that described shadow shield directly uses circuit board 2, and light source 3 is located on the circuit board 2, and is simple in structure.
In addition, in order more effectively to utilize light source 3 described shadow shields 13 to be attached with reflective membrane 11 near light source 3 one sides.Reflective membrane 11 be fixed on shadow shield 13 below, the general employing pasted or the mode of spraying.Reflective membrane 11 is provided with point-like or wire diffuse reflection projection or depression.Its material can adopt metal forming such as aluminium foil, also can adopt plastic sheeting, can also adopt plastic sheeting surface plating reflective membrane, can also be the papery film, but is preferably in papery film surface plating reflective membrane.The effect of reflective membrane 11 be with the light of light source 3 reflection (also can be refraction, scattering, transmission) to the reflective surface 61 of refractive body 6.
In addition, the refractive body in this example 6 is fixed on the housing of described equipment.Refractive body 6 can be tabular, be fixed in as shown in Figure 2 on the side of body plate on the back casing 1, also can be block, fixing (stickup) is in back casing 1 surface as shown in Figure 3, certainly can also be fixed on the back casing 1 by position limiting structures such as buckles, perhaps be buckled on procapsid 9 or the circuit board 2 by position limiting structures such as buckles.Concrete fixed form is known for those of ordinary skills, no longer describes.
The structure that this is routine, the housing of equipment comprise back casing 1 and procapsid 9, and it is inboard that display screen 7 is located at procapsid 9 place of windowing, and is provided with circuit board 2 in the space between back casing 1 and the procapsid 9.
Embodiment two
As Fig. 5 and shown in Figure 6, a kind of electronic equipment, different with embodiment one is that on each scheme basis of embodiment one, described display screen 7 lower surfaces also post 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.This light guiding film 4 can also weaken the light of reflection on the reflective surface 61 of refractive body 6, equalization, softening etc., makes the light of display screen 7 soft more clear.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation 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.
