Summary of the invention
Back lighting device irradiation at the above-mentioned mobile phone key plate of mentioning of the prior art is inhomogeneous, the shortcomings such as development of the slimming of limits product, the utility model provides a kind of new mobile phone key plate structure, it directly is formed with the optics site by modes such as hot pressing, laser engraving or ink printings on light guiding film, the optics site is arranged on the mobile phone key place, each button place is provided with the optics site district that a plurality of optics site is formed, and the shape in optics site district is identical with the button character shape at corresponding button place.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of mobile phone character light guide key plate, comprise light guiding film and be arranged on layer of silica gel below the light guiding film, the character on the light guiding film, English, stroke, function key, directionkeys place are provided with optics site district according to the shape of character, English, stroke, function key, directionkeys.
The technical scheme that its technical problem that solves the utility model adopts further comprises:
Place, Character segmentation district on the described light guiding film is provided with the optics site according to Character segmentation district shape.
Described optics site is outstanding spherical projection.
Described optics site is the spherical groove of depression.
Be provided with layer protecting film above the described light guiding film.
Be printed on character, English, stroke, function key and Character segmentation district on the described diaphragm.
Bonding between described light guiding film and the layer of silica gel by double faced adhesive tape.
Described light guiding film shape is less than layer of silica gel, and layer of silica gel is being provided with double faced adhesive tape greater than the light guiding film place, and the diaphragm shape is identical with layer of silica gel, and layer of silica gel is bonding by double faced adhesive tape.
The beneficial effects of the utility model are: the utility model utilizes light guiding film to carry out luminous from optics site on one's body; directly directly forming character by the optics site on the light guiding film shows; character brightness is even; and only contain light guiding film, diaphragm and layer of silica gel trilamellar membrane in the utility model; therefore, the slimming for mobile phone provides possibility.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
