DETAILED DESCRIPTION OF THE PREFERRED
Now conjunction with figs. explanation the preferred embodiments of the present invention.
See also Fig. 2 and Fig. 3, the present invention is the touch-controlled key structure 100 that is arranged in the mobile phone.The touch-controlled key structure 100 of present embodiment is made up of a module 10 backlight, one first insulation transparent film 20, one second insulation transparent film 30, one the 3rd insulation transparent film 40 and a hyaline membrane 50.
The first insulation transparent film 20 is arranged on the module 10 backlight, and is by the made transparent membrane of a kind of polyester material.In addition, the upper surface of the first insulation transparent film 20 is printed with electrically conducting transparent circuit 22, and the material of this electrically conducting transparent circuit 22 is the indium tin oxides (ITO) with good conductive characteristic.And in the present embodiment, electrically conducting transparent circuit 22 is the button circuits as touch-controlled key structure 100.Simultaneously, also have a linking part 24 on the side of the first insulation transparent film 20, electrically conducting transparent circuit 22 is the signal processing apparatus (not shown)s that are electrically connected at mobile phone by this linking part 24.
The second insulation transparent film 30 is arranged on the first insulation transparent film 20, and also is by the made transparent membrane of polyester material (the about 0.05mm of thickness).In addition, be to be formed with a plurality of through holes 32 on the second insulation transparent film 30.
Being arranged on the second insulation transparent film 30 of the 3rd insulation transparent film 40, and also be by the made transparent membrane of polyester material (the about 0.06mm of thickness).Lower surface at the 3rd insulation transparent film 40 is printed with a plurality of electrically conducting transparent points 42, and the position of electrically conducting transparent point 42 is the positions with respect to through hole 32, therefore, in the time of on the 3rd insulation transparent film 40 is arranged at the second insulation transparent film 30, electrically conducting transparent point 42 is to be positioned on the center of through hole 32, as shown in Figure 2.The position of above-mentioned electrically conducting transparent point 42 is also with respect to numeral on this light guide plate and figure.And in the present embodiment, electrically conducting transparent point 42 is the button points as touch-controlled key structure 100.Similarly, the material of electrically conducting transparent point 42 is the indium tin oxides (ITO) with good conductive characteristic.
When the touch-controlled key structure 100 of present embodiment was finished assembling, the second insulation transparent film 30 was as a spacer element, so made the electrically conducting transparent point 42 of the 3rd insulation transparent film 40 be unlikely the electrically conducting transparent circuit 22 of the contact first insulation transparent film 20.
See also Fig. 4, when the touch-controlled key structure 100 of present embodiment during in the holding state of mobile phone, what shown on the panel of touch-controlled key structure 100 only is pattern 52 on the hyaline membrane 50.
See also Fig. 5, when mobile phone had incoming call or user's desire to use mobile phone, module 10 backlight just can send backlight and penetrate hyaline membrane 50 at this moment.Because the pattern 52 on the hyaline membrane 50 is drawn and can be made backlight penetrating with printing opacity printing ink, and the surface on the light guide plate 12 121 is printed with numeral and figure and makes backlight can't penetrating, and can form the shade of numeral and figure, therefore, just can see numeral and figure on the light guide plate 12 from the panel of touch-controlled key structure 100.At this moment, if the user pushes by numeral of being seen on the panel and figure, can make the electrically conducting transparent point 42 on the 3rd insulation transparent film 40 touch corresponding electrically conducting transparent circuit 22 on the first insulation transparent film 20, issuing a signal transmitted to the signal processing apparatus (not shown) of mobile phone, and do further output and handle.
As mentioned above, touch-controlled key structure 100 of the present invention has following several advantages compared to existing press-key structure:
(1) make mobile phone have more function attractive in appearance and that decorate.
(2) pattern on the panel can be changed at any time and arbitrarily.
(3) it is comprehensive making the key-press backlight of mobile phone.
(4) make the front appearance of mobile phone be different from the existing mobile phone outward appearance fully.
(5) integral thickness of mobile phone is reduced.
Though the present invention is exposed in conjunction with the preferred embodiments; yet it is not in order to limit the present invention; those skilled in the art without departing from the spirit and scope of the present invention; can make a little change and retouching, so protection scope of the present invention should be looked the accompanying Claim book person of defining and is as the criterion.
