Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skills belong to protection domain of the present utility model not making the every other embodiment that obtains under the creative work prerequisite.
Below in conjunction with accompanying drawing, the utility model embodiment 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 electronic equipment simultaneously, the general LED lamp that adopts of light source 3.Described refractive body 6 comprises reflective surface 61, described reflective surface 61 is relative with described display screen 7 lower surfaces, be attached with the first reflective membrane 5 on described reflective surface 61, refractive body 6 and on the first reflective membrane 5 be used for replacing backlight assembly of the prior art and provide backlight for display screen 7.
In this example, form cavity 12 between described the first reflective membrane 5 and 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 simultaneously prior art, to adopt the 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; In 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 can be located at the side of display screen 7, can reduce the distance of formation between the first reflective membrane 5 and described display screen 7, has dwindled further the volume of equipment.Certainly light source 3 can be arranged at any position in electronic equipment, as long as it is just passable that its light can shine the first reflective membrane 5, 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 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 procapsid 9, then by the wire powered operation.
This realize better reflection of light, between described reflective surface 61 and 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 described display screen 7 increases from the curved edges to the center of surface gradually; More be conducive to the reflection of light.
In addition, be provided with point-like or wire diffuse reflection projection or depression on the first reflective membrane 5.Its material can adopt metal forming such as aluminium foil, also can adopt plastic sheeting, can also adopt plastic sheeting plated surface reflective membrane, can also be the papery film, but is preferably in papery film plated surface reflective membrane.The effect of the first reflective membrane 5 is to form the light reflection of light source 3 (can be also refraction, scattering, transmission) to display screen 7 back sides backlight.The point-like on the global shape of the first reflective membrane 5 and surface or wire diffuse reflection projection or depression should be made according to fundamental reflection (can be also refraction, scattering, the transmission) principle of optics, can guarantee to provide suitable backlight being as the criterion as display screen 7, can complete in conjunction with experiment by Theoretical Design, be that those of ordinary skill in the art need not the creative work person just can complete smoothly, no longer describe in detail.
The first reflective membrane 5 is fixed on the reflective surface 61 of refractive body 6, generally adopts bonding method.By this kind mode, removed the backlight modular construction, make the structure of equipment simpler, assemble simpler and easyly, and cost is lower, can reach existing screen intensity fully simultaneously, satisfies user's use.
In addition, the first reflective membrane 5 can also be to be sprayed at the reflective membrane that forms on reflective surface 61; This scheme is general direct sprays reflectorized material on reflective surface 61, reflectorized material can be fluorescent paint, aluminium paint etc.This scheme is normally directly produced point-like or wire diffuse reflection projection or depression on reflective surface 61, then sprays reflective membrane.
In addition, described the first reflective membrane 5 can also be the reflective membrane that directly plates on reflective surface 61; This scheme is plastic sheeting plated surface reflective membrane normally, can be also at papery film plated surface reflective membrane.
In order to prevent that light source 3 light from appearing apparatus casing, this equipment also comprises shadow shield 13, is used for stopping that light source 3 light shine in housing, perhaps, directly adopts 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 is simple in structure.
In addition, in order more effectively to utilize the described shadow shield 13 of light source 3 to be attached with the second reflective membrane 11 near light source 3 one sides.The second reflective membrane 11 be fixed on shadow shield 13 below, the general employing pasted or the mode of spraying.Be provided with point-like or wire diffuse reflection projection or depression on the second reflective membrane 11.Its material can adopt metal forming such as aluminium foil, also can adopt plastic sheeting, can also adopt plastic sheeting plated surface reflective membrane, can also be the papery film, but is preferably in papery film plated surface reflective membrane.The effect of the second reflective membrane 11 be with the light reflection of light source 3 (can be also refraction, scattering, transmission) to the first reflective membrane 5.
In addition, the refractive body in this example 6 is fixed on the housing of described equipment or is integrated with housing.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 procapsid 9.
Embodiment two
As Fig. 5 and shown in Figure 6, a kind of electronic equipment, different from embodiment one is, 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 first reflective membrane 5, equalization, softening etc., makes the light of display screen 7 more soft clear.
The above; it is only the better embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement are within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
