Embodiment
Please consult simultaneously shown in Fig. 2 A and Fig. 2 B, Fig. 2 A is one embodiment of the invention touch control panel device synoptic diagram; Fig. 2 B is the synoptic diagram of the flexible circuit board of one embodiment of the invention touch control panel device.Being touch control panel device 2 front plan view and side view shown in Fig. 2 A, is flexible circuit board 22 front plan view and side view shown in Fig. 2 B.
Touch control panel device 2 is applied in the electronic installation, as: mobile phone, personal digital assistant device, notebook computer input media and other portable electronic devices etc.; Touch control panel device 2 comprises a touch module and a plurality of metallic gasket 240.Wherein, touch module can be the kenel of general condenser type, electromagnetic type or resistance-type, and those skilled in the art can implement because it belongs to, and are therefore no longer given unnecessary details explanation.
Touch module has a Trackpad 20 and a flexible circuit board 22.Wherein, Trackpad 20 is a touch control panel device and user's the interface that contacts, and utilizes a kind of thermoplasticity, light-permeable or semi-transparent plastic cement material to make, as: Polyurethane glue film (TPU, Thermoplastic Polyurethane Pellet); Flexible circuit board 22 is positioned at Trackpad 20 belows, has a plurality of holes 222 and a plurality of sensing elements 220.A plurality of holes 220 are rectangular to be arranged, and is that any sensing element 220 is holed with the gap between the sensing element 220 and got in property circuit board 22; Design according to the pore size between employed sensing element, the pore diameter range of hole 220 is 0.6mm to 2.0mm.
A plurality of metallic gaskets 240 are arranged at the bottom surface below ad-hoc location of flexible circuit board 22, more corresponding a plurality of sensing elements 220 belows that are placed on, and wherein, each metallic gasket 240 is promptly represented the position of a special function keys.Wherein, a plurality of metallic gaskets 240 can directly be arranged at flexible circuit board 22 lower surfaces with it according to circuit design, or the one section space that is separated by is arranged at flexible circuit board 22 belows, the order that reaches the sense of touch when pushing well and make flexible circuit board 22 transmit this function key of being pushed is with this function of smooth execution.The big I of metallic gasket is done a design adjustment according to sense of touch and actual required function bond number amount again.
When the user pushes some metallic gaskets 240 (function key), because of having a plurality of holes 222 on the flexible circuit board 22, thus can increase its pliability and avoid flexible circuit board 22 and the excessive deformation of Trackpad 20 and then the influence institute Trackpad of pushing 20 around the false sense of sensing element 220 answer.
Wherein, a plurality of holes 222 are arranged at the gap between sensing element 220 and the sensing element 220, so can avoid destroying the function of a plurality of sensing elements 220, in the time of can preventing that the user from pushing touch module again, the excessive deformation of touch module also increases pliability and serviceable life.When the user will point or tool in contact such as light pen on Trackpad 20 time, the voltage of flexible circuit board 22 will change to some extent, with sensing user touch position, and produces corresponding vernier signal control with the vernier displacement on the screen of electronic installation.
Right the present invention is only limited to this embodiment, sees also Fig. 3 A and Fig. 3 B simultaneously, and Fig. 3 A is another embodiment of the present invention touch control panel device synoptic diagram; Fig. 3 B is the synoptic diagram of the flexible circuit board of another embodiment of the present invention touch control panel device.
Its principle is as the embodiment of above-mentioned Fig. 2,322 borings of a plurality of holes on its flexible circuit board 32 are arranged at the space on every side that sensing element 320 belows have metallic gasket 340, cause when avoiding the user to push the excessive deformation of flexible circuit board 32 and Trackpad 30 and then the sensing element 320 around the influence institute Trackpad of being pushed 30 false sense should, and improve pliability and increase serviceable life.And this type of conversion is the equivalent transformation of structure of the present invention and known by being familiar with present technique field person, so do not repeat them here.
See also shown in Figure 4ly, be one embodiment of the invention touch control panel device practical application synoptic diagram.It shown in the figure input media of an electronic installation, comprise a plurality of function keys and a touch control panel device, wherein, utilize the mode of transfer printing to indicate a plurality of function key symbols on the Trackpad 40, all have a metallic gasket (representing with frame of broken lines) under each symbol, its Trackpad 40 is a smooth plane, is user-friendly for touch controllable function, the function of can also the mode of pushing carrying out special function keys is as direction of input arabic numeral or control upper and lower, left and right or the like.
Among the present invention, touch control panel device is by increasing a plurality of metallic gaskets in the touch module below, and in the improvement of the flexible circuit board interface structure of touch module, promptly on flexible circuit board, bore a plurality of holes, in the time of can effectively avoiding pushing Trackpad, easily cause the deformation kenel of flexible circuit board and Trackpad on every side, improve the pliability of touch module because of compressive stress concentrates on single point, and increase depressible different function key, to promote the functional of touch control panel device.
Though the present invention illustrates as above with preferred embodiment, so it is not only to terminate in the foregoing description that in order to limit spirit of the present invention and entity of the present invention.So, having in any affiliated technical field and know the knowledgeable usually, the modification of being done in without departing from the spirit or scope of the invention all should be included in the following request item.
