Embodiment
Below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in Figure 1, a kind of contact panel with pressure sensitive function, is characterized in that, comprises the cover plate 1, two-dimentional touch-control module 2 and the pressure touch module 3 that set gradually from top to bottom.
Particularly, two-dimentional touch-control module 2 comprises touch-control sensing sheet 21 and flexible circuit board 1, and touch-control sensing sheet 21 is provided with two-dimentional touch-control sensing electrode.
Particularly, pressure touch module 3 comprises pressure sensitive sheet 31 and flexible circuit board 2 32, and pressure sensitive sheet 31 is provided with pressure sensitive electrode.
Particularly, touch-control sensing sheet 21 is connected with flexible circuit board 1 by ACF, and flexible circuit board 1 is provided with conducting PAD221.
Particularly, pressure sensitive sheet 31 is connected with flexible circuit board 2 32 by ACF, and flexible circuit board 2 32 is provided with elasticity conducting contact 321.
Particularly, cover plate 1 and touch-control sensing sheet 21 are fitted by optical cement, and pressure sensitive sheet 31 is attached on handset front case 4 by bonding agent, and touch-control sensing sheet 21 and pressure sensitive sheet 31 exist cavity interval.Owing to there is cavity interval, when finger presses cover plate 1 is, due to the effect of power, cover plate 1 there will be certain deformation, thus drive the touch-control sensing sheet 21 of fitting with cover plate 1 that certain deformation occurs, the distance between touch-control sensing sheet 21 and pressure sensitive sheet 31 is changed, electric capacity is between the two changed, the two-dimensional coordinate position simultaneously coordinating touch-control sensing sheet 21 to be detected in, calculates the pressure Force location acting on cover plate 1 then by certain algorithm.Simultaneously, because pressure sensitive sheet is attached on handset front case 4, this mode allow touch-control sensing sheet 21 show module with mobile phone before adopt the mode of entirely fit to be connected, while making the implantable pressure touch controllable function of mobile phone, still can retain the superior visual effect of entirely fitting.
Particularly, at cover plate 1 with under the extruding of handset front case 4, the conducting PAD221 on flexible circuit board 1 contacts with the conducting contact 321 on flexible circuit board 2 32 and conducting.Because touch-control sensing sheet 21 needs connect but directly do not contact with pressure sensitive sheet 31, adopt this conduction mode, can when final assembly, first assembling pressure touch-control module refills joins miscellaneous part, makes assembling process flow process more, more possesses controllability.
As better selection, the elasticity conducting contact 321 of flexible circuit board 2 32 is conducting foam, elasticity conducting probe or conducting resinl.
Certainly, flexible circuit board 1 and flexible circuit board 2 32 can also carry out conducting by connector, ACF pressing or scolding tin.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
