Abstract
The utility model discloses a partitioned light-guiding keyboard and a mobile terminal. The partitioned light-guiding keyboard comprises a keycap, a light-shielding film and a light-guiding plate, compound silica gel and a DOME, wherein the keycap, the light-shielding film, the light-guiding plate, the compound silica gel and the DOME are sequentially arranged from top to bottom; the light-shielding film is provided with transparent holes, the compound silica gel is transparent at the keycap, and the rest part is nontransparent; and a light-guiding film is arranged on the DOME. Through the utility model, no mutual-interference influence among light-emitting zones of the keyboard is realized.
Description
Technical field
The utility model relates to the communications field, relates in particular to a kind of subregion leaded light keyboard and portable terminal.
Background technology
The divisional light emission of keyboard can be accomplished the keyboard region light operated, and all the other inactive districts do not work.Allow the user bring convenience efficiently simultaneously, also give the enjoyment of aesthetic feeling.
EL (electroluminescence, Electro Luminesence) is backlight once to be the solution of keyboard subregion leaded light.But because EL cost backlight is higher, produce complexity, especially there is the term of validity in semi-finished product, cause using at present fewer and feweri.How to adopt a kind of low cost, productibility is good, and effective mode realizes divisional light emission, becomes designer's pursuit.
In the correlation technique, adopt LGF (light guiding film LIGHT GUIDE FILM) usually.But in the divisional light emission scheme, exist all the time between different luminous zones mutually interfere, interactional problem.
The utility model content
The utility model provides a kind of subregion leaded light keyboard and portable terminal, has solved the problem that influences each other, interferes between the keyboard luminous zone.
To achieve these goals, according to an aspect of the present utility model, provide a kind of subregion leaded light keyboard.
Comprise keycap, photomask according to subregion leaded light keyboard of the present utility model, this subregion leaded light keyboard also comprises light guide plate, compound silica gel, DOME, and wherein keycap, photomask, light guide plate, compound silica gel, DOME set gradually from top to bottom; Photomask is provided with loophole, and compound silica gel is at keycap place printing opacity, and remainder is light tight; DOME is provided with light guiding film.
Further, the light guide plate downside is provided with first light shield layer.
Further, first light shield layer is that the shading bubble is continuous.
Further, the photomask surface is provided with second light shield layer, and the position is corresponding in the vertical with second light shield layer for first light shield layer.
Further, first light shield layer and second light shield layer are that the shading bubble is continuous.
Further, compound silica gel is by silica gel and the composite molding of thermoplastic elastic body rubber TPU film.
To achieve these goals, according to another aspect of the present utility model, provide a kind of portable terminal.
Comprise above-mentioned subregion leaded light keyboard according to portable terminal of the present utility model.
By the utility model, adopt two different light pathes, realized not mutual interference effect between the keyboard luminous zone.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 is the textural association figure of the utility model embodiment subregion leaded light keyboard;
Fig. 2 is the STRUCTURE DECOMPOSITION figure of the utility model embodiment subregion leaded light keyboard;
Fig. 3 is the partial exploded view under the keycap of the utility model embodiment subregion leaded light keyboard;
Fig. 4 is the profile of the utility model embodiment subregion leaded light keyboard.
Embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Adopt subregion leaded light keyboard of the present utility model, having reached can divisional light emission, and the effect of interference effect mutually not between the luminous zone, and cost is lower, and productivity is better.
Advantage is: by innovative design to structure, at lower cost, and better productibility, satisfied effect has solved keyboard subregion leaded light problem, will become one of effective scheme of this type of problem of solution.
This patent is by the creative utilization to prior art, by novel structure, with the advantage organic assembling of LGF.Variation by keyboard technology simultaneously, having reached can divisional light emission, and the not design of interference effect mutually between the luminous zone.Cost control that the more important thing is realization is better, and cost performance is good.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model embodiment provides a kind of subregion leaded light keyboard to be divided into 5 layers, is followed successively by keycap 9, photomask 7, light guide plate 6, compound silica gel 4, DOME (the young sheet of pot) 2 from top to bottom.
DOME2 is provided with light guiding film (LGF, LIGHT GUIDE FILM), as a conducting light path.
Compound silica gel 4 is by silica gel and TPU (Thermoplastic polyurethanes, thermoplastic elastic body rubber) film composite molding, and at keycap 9 place's printing opacities, remainder is light tight, can allow first via light path appear from keycap 9.
Photomask 7 is provided with loophole 10, can allow the second tunnel light path appear from loophole 10.
First via light path: (lead on the compound silica gel 4, three transparent area A, B, C showing by Fig. 4 appear two LED lamp 1, and three symbols are lighted by the light guiding film on the DOME2.
The second tunnel light path: LED lamp 3 shines on the light guide plate 6, makes whole light guide plate bright, and the D, the E district that show by Fig. 4 appear light.D, E transparent area are to open printing opacity mouth 10 by photomask 7 in opposed area to realize.
The utility model has realized that first via light path and the second tunnel light path isolate, and has realized divisional light emission, and the mutually noninterfere influence has solved luminous and non-luminous fuzzy boundary between the luminous zone, makes that different luminous zones are clear to be presented.
Preferably, light guide plate 6 downsides are provided with first light shield layer 5, and photomask 7 surfaces are provided with second light shield layer 8, and the position is corresponding in the vertical with second light shield layer 8 for described first light shield layer 5, can increase the effect of isolating light.First light shield layer 5 and second light shield layer 8 can adopt the shading bubble continuous.
In addition, above-mentioned subregion leaded light keyboard can be applied in the portable terminal, thereby can be at lower cost, better productibility, and satisfied effect has solved keyboard subregion leaded light problem, and then improves user experience.
In sum, according to the foregoing description of the present utility model, a kind of subregion leaded light keyboard and portable terminal are provided.By adopting two different light pathes, realized not mutual interference effect between the keyboard luminous zone.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
