Description
The application is application number is 200810172344.5, and the applying date is on October 31st, 2008, and denomination of invention is the divisional application of " method for making of camber-shaped capacitance type touch-control plate and structure thereof ".
Technical field
The present invention relates to a kind of structure of camber-shaped capacitance type touch-control plate, particularly a kind of system of being moulded by capacitive touch control plate forms curved touch pad structure.
Background technology
Existing comparatively common plane Trackpad (Touch Panel), includes resistance-type and capacitive touch control plate; Wherein, there is in capacitive touch control plate a touch-control circuit, the gold-tinted processing procedures such as exposure, development, etching can be utilized, by transparent conductive material (tin indium oxide Indium Tin Oxide, ITO) be stacked on the surface of a transparency carrier one by one, and become a transparent capacitive touch control plate; Or described touch-control circuit also can be a flexible circuit board (FLEXBILPRINTED CIRCIT, FPC), described flexible circuit board directly fits with described substrate, and become a nontransparent capacitive touch control plate; So, the capacity effect produced between described touch-control circuit and human body can be utilized, to calculate the coordinate of its position of touch.
And know, current photovoltaic by advanced be main flow with curved design; Therefore, when product design, its surface set up some physical buttons and art designing seam, the curvature of product surface can be caused inharmonious, and increase described in the curved design on surface and the degree of difficulty of manufacture; In addition, relate to the correlation technique of above-mentioned curved product at present, as seen in the convex surface liquid crystal display that No. 1110377th, BrP, No. 2002341323rd, Jap.P., Chinese patent No. 1612185 (publication number) and Youda Photoelectric Co., Ltd (AUO PTRONIC SCORP.) publish in June, 2008 and show; But described technology is the curved surface application about safety glass or LCD, and all not mentioned curved surface about Trackpad is applied.
In view of this, in comparatively advanced technology, disclose the correlation technique of the curved design about above-mentioned Trackpad, visible No. 6654071st, United States Patent (USP), be to provide a kind of can free bending becomes curved soft capacitive touch control plate according to the arc curvature of display surface, be used for being attached to the surface of described display, cause described displaying appliance for touch controllable function; In addition, No. 1479891st, Chinese patent (publication number), also provides a kind of bending capacitance touch pad, is establish a functional membrane between two bending rigid transparent fenders, and possesses touch-control ability; But, the touch pads of the Trackpad that No. 6654071st, United States Patent (USP) and No. 1479891st, Chinese patent all only can along an axis (as described in the longitudinal axis of Trackpad or transverse axis) bend to curved, and cannot be formed have multiaxis to bending curve, and do not disclose described Trackpad and the method for making of touch pads; Therefore, for above-mentioned Trackpad is made into curved, still also existing manyly technically has problem to be overcome.
