Abstract
The utility model provides a light guide film switch structure for a notebook computer keyboard, which is thinner in overall thickness and comprises an upper-layer circuit board and a light guide plate; an electrode is printed on the lower end surface of the upper-layer circuit board; an insulating layer is arranged at the periphery of a conducting point; the insulating layer is attached to the lower end surface of the upper-layer circuit board; and the switch structure is characterized in that the light guide plate is arranged under the insulating layer, the conducting point is printed on the upper end surface of the light guide plate, and the conducting point corresponds to the electrode of the upper-layer circuit board. The light guide plate is attached together with the insulating layer through optical cement or attached together with the upper-layer circuit board through the optical cement. The insulating layer is a plastic film or an UV (ultraviolet) film. Compared with the prior art, the light guide film switch structure of the notebook computer keyboard is thinner, and can meet the requirement of the market on a thin-type film switch with backlight.
Description
Technical field
The utility model relates to a kind of notebook computer leaded light keyboard member, particularly a kind of keyboard of notebook computer light-leading film construction of switch.
Background technology
In the thin film switch structure of keyboard of notebook computer, add light guide plate (LGF), local light can be guided to whole keyboard, make character even whole keyboard on each button all send light (as present cell phone keyboard).Therefore can be at the dark place or the more weak place of light use.When online or work, can open a lamp less, promptly advocate energy-conserving and environment-protective, also satisfy part consumer's creativity consciousness, convenient service more is provided.
Prior art as shown in Figure 1 have a keyboard of notebook computer thin film switch structure backlight, among the figure the 1, the 3rd, the levels wiring board of thin film switch, the 2nd, insulating barrier, the 4, the 5th, thin film switch levels keyboard contact point, the 6th, light guide plate (LGF), the 7th, optical cement.This technical pattern is thin film switch and light guide plate, is bonded together with the novel optic material, thereby finishes combination electric and light.But this integrally-built thickness is thicker, at computer and keyboard under the epoch of attenuation drive gradually, makes our thin film switch also in requisition for attenuate.
Summary of the invention
The utility model provides a kind of keyboard of notebook computer light-leading film construction of switch, and purpose is to solve the prior art problem, provides a kind of thickness the keyboard of notebook computer light-leading film construction of switch thinner than prior art, to satisfy the needs in market.
The utility model technical scheme that adopts of dealing with problems is:
Keyboard of notebook computer light-leading film construction of switch, include upper layer circuit plate, light guide plate, upper layer circuit plate lower surface is printed with electrode, be provided with insulating barrier around the conductiving point, insulating barrier sticks on upper layer circuit plate lower surface, light guide plate is located at the insulating barrier below, is printed with conductiving point in the light guide plate upper surface, the corresponding setting of electrode on this conductiving point upper layer wiring board.
Light guide plate is pasted together with insulating barrier by optical cement.
Light guide plate is pasted together by optical cement upper layer wiring board.
Described insulating barrier is plastic film or UV film.
The beneficial effects of the utility model: the utility model will directly be printed on the light guide plate with the corresponding conductiving point of electrode in the upper layer circuit plate, save lower floor's wiring board, and the overall structure thickness of its thin film switch reduces.Simultaneously, not only improved the difficulty that circuit prints on light guide plate because putting corresponding position with button on light guide plate has only printed a point, and since the figure line on the light guide plate is less can be to the leaded light performance production capacity negative effect of light guide plate yet.For further reducing the integral thickness of thin film switch, the median septum layer can be replaced with printing material UV, thereby reduce material, reduced manufacturing cost, and more a step has reduced integral thickness.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is the structural representation of embodiment 1;
Fig. 3 is the structural representation of embodiment 2.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Keyboard of notebook computer light-leading film construction of switch as shown in Figure 2 includes upper layer circuit plate 10, and upper layer circuit plate 10 lower surfaces are printed with electrode 20, and electrode 20 is corresponding with the button point on the key layer.Be provided with insulating barrier 30 around the electrode 20, insulating barrier 30 sticks on upper layer circuit plate 10 lower surfaces.Light guide plate 40 is located at insulating barrier 30 belows, is printed with conductiving point 50 in light guide plate 40 upper surfaces, the electrode 20 corresponding settings on these conductiving point 50 upper layer wiring boards.Wherein the insulating barrier in the present embodiment 30 adopts plastic film, because the restriction of existing technology, the area of its plastic film is bigger, so light guide plate 40 is pasted together with insulating barrier 30 by optical cement 60.For further reducing the integrally-built thickness of thin film switch, insulating barrier 30 in this structure can adopt the UV film, with the UV film printing on upper layer circuit plate 10 lower surfaces, if just the UV printing area is equally big with the area of plastic film, can increase the difficulty of production process, so the preferred forms of structure is that insulating barrier adopts plastic film in the present embodiment.
Keyboard of notebook computer light-leading film construction of switch as shown in Figure 3, identical among its layer of structure and the embodiment 1, just the insulating barrier in the present embodiment 30 ' adopts the UV film, the UV film printing is in upper layer circuit plate 10 ' lower surface, according to prior art, the area of printing UV film is less, and therefore in the outside of UV film, light guide plate 40 ' is pasted together by optical cement 60 ' upper layer wiring board 10 '.Wherein insulating barrier 30 ' also can adopt plastic film in this structure, just adopt plastic film to make its production process complicated more in this structure, so the structure preferred forms in the present embodiment is that insulating barrier adopts the UV film.Adopt the UV film that overall structure thickness is reduced in the present embodiment, and reduced the material that insulating barrier uses, reduced manufacturing cost.
To directly be printed on the light guide plate with the corresponding conductiving point of electrode in the upper layer circuit plate among above-mentioned two embodiment, and save lower floor's wiring board, the overall structure thickness of its thin film switch reduces.Simultaneously, not only improved the difficulty that circuit prints on light guide plate because putting corresponding position with button on light guide plate has only printed a point, and since the figure line on the light guide plate is less can be to the leaded light performance production capacity negative effect of light guide plate yet.
