Embodiment
Please be simultaneously with reference to shown in Fig. 2 A and Fig. 2 B, Fig. 2 A is the synoptic diagram of the touch-control input device of the utility model one embodiment; Fig. 2 B is the flexible circuit board synoptic diagram of the touch-control input device of the utility model one embodiment.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 input device 2 is applied in the electronic installation, as: mobile phone, personal digital assistant, notebook input media and other portable electronic devices etc.; Touch-control input device 2 can be the kenel of general condenser type, electromagnetic type or resistance-type, because it is that the person of ordinary skill in the field can implement, is therefore no longer given unnecessary details explanation.
Touch-control input device 2 comprises contact panel 20, flexible circuit board 22, rubber blanket 24 and a plurality of metallic gasket 26.Wherein, contact panel 20 is touch-control input device and user's a contact interface, and the user is provided input interface, utilizes a kind of thermoplasticity, light-permeable or semi-transparent plastic material to make, as: Polyurethane glue film (TPU, Thermoplastic Polyurethane Pellet).
A plurality of metallic gaskets 26 can be linked to rubber blanket 24 lower surfaces, can it directly be connected surface on the flexible circuit board 22b of lower floor according to circuit design, or the one section space that is separated by is in the face of (relatively) surface on the flexible circuit board 22b of lower floor, the order that reaches the sense of touch when pushing well and make flexible circuit board 22 transmit this function key 26 of being pushed is with this function of smooth execution.The big I of metallic gasket is done design adjustment according to sense of touch and actual required function bond number amount again.
When the user is contacted with finger on the contact panel 20 or pushes some metallic gaskets 26 (function key), or when utilizing tool in contact such as light pen on contact panel 20, the voltage of flexible circuit board 22 will change to some extent, with sensing user touch position, and on the screen of electronic installation, produce corresponding cursor signal and cursor displacement control; And because of adding rubber blankets 24 in the middle of the flexible circuit board 22,, and avoid the excessive deformation of flexible circuit board 22 and contact panel 20, and then the false sense that influences institute's pressing position sensing component 220 is on every side answered so can increase the pliability of touch-control input device.
Please refer to Fig. 3, be the touch-control input device use synoptic diagram of the utility model one embodiment.Its principle is as above-mentioned, and when the user stayed in its finger on the contact panel 20, flexible circuit board can rest on the time length of same fixed point on the contact panel according to user's finger to judge that the user is to use touch controllable function or pressing function.
When the user stays on the contact panel, the area that can surpass a sensing component 220 because of the contact pressure area of finger usually, as shown in FIG., promptly when the user desires to push the function key on the left side, its finger area of pushing will comprise contiguous this function key sensing component (being the scope shown in the dotted arrow) all around; Therefore, touch-control input device receives induced signal, and judges if surpassing 25ms user does not move through as yet to inferior one adjacent inductive component 220 (being the scope shown in the solid arrow), is considered as the function that desire is carried out pressing function key 26.Then touch-control input device is carried out pressing function, and suspends the touch-control input device touch controllable function.
In the utility model, touch-control input device is by increasing a plurality of metallic gaskets between flexible circuit board, and at the middle rubber blanket that adds of the flexible circuit board of touch-control module, in the time of can effectively avoiding pushing contact panel, because of concentrating on single point, compressive stress easily causes the deformation of flexible circuit board and contact panel on every side, improve the pliability of touch-control input device, and increase the different function key that to push, to promote the functional of touch-control input device.
Though the utility model is illustrated as above with preferred embodiment, so it is not only to terminate in the foregoing description in order to spirit and the utility model entity that limits the utility model.Be that the modification of being done in spirit that does not break away from the utility model and scope all should be included in the claim with, any person of ordinary skill in the field.
