Detailed description of the invention
The specific embodiment that the present invention is presented herein below further describes:
The open a kind of capacitance touch flexible keyboard of the present invention, including following feature: as it is shown on figure 3, a PET and electrode layer 21,
Second glue-line 22, the 3rd protection decorative layer 23, flexible circuit board 24, can bend.
Oneth PET and electrode layer 21, for electrically conducting transparent optical material, base material is polyethylene terephthalate, on it
Face sputter covers conductive material tin indium oxide, and the present embodiment PET base material thickness uses 100um, a PET and electrode layer 21 conduct
Basic unit and functional layer, be placed on the bottom of whole product design.
Above the tin indium oxide of the upper surface of the oneth PET and electrode layer 21, it is designed with and realizes keyboard touch function pattern 31,
Whole functional pattern 31, is combined by organizing keyboard Designing unit pattern 311 more.
The common keyboard number of keys minimum combination touch-control core individual more than 70, above the present embodiment flexible circuit board 24
Sheet, the function input port number 40 that its support is total, therefore one group of keyboard Designing unit pattern 311 of the present embodiment, uses every two
Bar touch signal passage realizes 4 keyboard button functions.
As it is shown in figure 5, illustrate for one of which unit pattern 311,41,42,43,44 for keyboard wherein 4 press
Key position, line pattern 411,441, one end connects two signalling channels of touch chip respectively, and other end is at corresponding button
Position, the sensing that intersects forms dendroid or E shape pattern such as 421,422,431,432, formation node capacitor C1, C2, C3,
C4, its equivalent circuit is as shown in Figure 6.Touching corresponding key position, chip, according to the change of node capacitor amount, calculates coordinate
Point, thus realize keyboard button function.
Second glue-line 22, for OCA solid transparent optical cement, is fitted on a PET and electrode layer 21, and the present embodiment selects
Bubble and the reliability of whole keyboard is reduced with the laminating of the optical cement of 100um thickness, beneficially product.
3rd protection decorative layer 23, according to the design on PET and electrode layer 21, button character different in printings with
Decorative appearance pattern, pasted with a PET and electrode layer 21 by the second glue-line 22 together with.
