Description
Technical field
The utility model belongs to a kind of portable type electronic product, specifically, relates to a kind of light-guiding mechanism and portable mobile termianl, belongs to field of mechanical technique.
Background technology
Along with the extensive use of portable mobile termianls such as mobile phone, employed eyeglass is increasing, especially has the touch-type mobile terminal of large scale eyeglass, and shared proportion also is increasing in portable terminal market.
Touch-type mobile terminal usually is provided with the membrane keyboard shortcut icon, and shortcut icon is set on the eyeglass outside the viewing area, generally; Coordination for integral body; Shortcut icon generally is set at the upper surface of LCD module, because the thickness of portable mobile termianl is more and more littler, the gap between eyeglass and the LCD module is very little here; At present, portable mobile termianl backlight also is not set herein.
In realizing process of the present invention; The inventor finds to exist at least in the prior art following problem, when the membrane keyboard shortcut icon of touch-type mobile terminal is arranged on the eyeglass outside the viewing area, owing to do not have backlight; Just there is not light from the membrane keyboard shortcut icon, to appear; When the user used under the half-light line states, the membrane keyboard shortcut icon was very dark, used inconvenient.
The utility model content
The technical problem that the utility model will solve is to above deficiency; A kind of light-guiding mechanism and portable mobile termianl are provided; Having overcome in the prior art membrane keyboard shortcut icon does not have backlightly, uses inconvenient defective, more is applicable to the portable mobile termianl that thickness is less.
For solving above technical problem, the utility model adopts following technical scheme: a kind of light-guiding mechanism comprises eyeglass and LCD module; Eyeglass is arranged on the LCD module, and the LCD module has the viewing area, and eyeglass comprises two parts; Wherein a part is corresponding with the viewing area; Another part is arranged on outside the viewing area, and the eyeglass outside the viewing area is provided with the membrane keyboard icon, it is characterized in that: said light-guiding mechanism also comprises:
Light guide sheet is arranged between eyeglass and the LCD module, and light guide sheet is corresponding with the position of membrane keyboard icon;
The LED spot light is arranged on the edge of light guide sheet, and light guide sheet conducts to the membrane keyboard icon with the light of LED spot light.
A kind of prioritization scheme, said LED spot light is the side-emitting LED spot light.
Another kind of prioritization scheme, said membrane keyboard icon is arranged on the eyeglass of below, viewing area.
Another prioritization scheme is provided with double faced adhesive tape between the LCD module at edge, said viewing area and the eyeglass.
A kind of concrete prioritization scheme, said light guide sheet are arranged between the eyeglass and LCD module of double faced adhesive tape below.
Another kind of concrete prioritization scheme, the below of said LCD module is provided with secondary pcb board, and the LED spot light is arranged on the secondary pcb board.
The prioritization scheme that another is concrete, the below of said light guide sheet is provided with support.
Prioritization scheme further, the bottom of said LCD module is provided with zinc alloy layer.
Said light guide sheet is the TP light guide sheet.
Based on above-mentioned light-guiding mechanism, the utility model provides a kind of portable mobile termianl that adopts said light-guiding mechanism design again, comprises the described light-guiding mechanism of arbitrary technical scheme in the technique scheme.
After the utility model adopts above technical scheme, compared with prior art, have the following advantages: light guide sheet is arranged between eyeglass and the LCD module, and light guide sheet is corresponding with the position of membrane keyboard; The LED spot light is arranged on the edge of light guide sheet, and light guide sheet conducts to the membrane keyboard icon with the light of LED spot light, and the gap that has solved between present eyeglass and the LCD module is little, and the membrane keyboard icon can't be realized problem backlight.Adopt the light guide sheet conducting light, so the even back of membrane keyboard icon; Adopt the side-emitting LED spot light, the position of LED lamp can arbitrarily be adjusted, and flexibility ratio is high; Because light guide sheet is to be clipped between eyeglass and the LCD module, has filled the gap between eyeglass and the LCD module, eyeglass is no longer unsettled, has increased the intensity of portable mobile termianl; Adopt mouthful word glue that LCD module and eyeglass are combined, eyeglass and viewing area LCD module is on every side sealed fully, avoided dust to enter into the inner surface of eyeglass; Different multiple colors can be coated in the surface of light guide sheet, so use a kind of LED lamp of color, can access many backlight colors.
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
