The utility model content
As aforementioned said, traditional projecting type capacitor contact panel damages because of the diaphragm on surface and transparency electrode are subject to scratch, is not suitable for making key panel; Therefore the utility model fundamental purpose is to provide a kind of capacitance type touch control keys panel, and it has the characteristic of capacitance type touch-control panel, can avoid transparency electrode to be subject to scratch again and the problem damaged.
For reaching the major technique means that aforementioned purpose takes is to make aforementioned capacitance type touch control keys panel, includes:
One substrate; Be regular shape; Have a relative surface and a bottom surface; Its bottom surface is formed with more than one induction electrode respectively, a ground plane, connects socket, connects induction electrode and the lead that is connected socket more than one, and wherein ground plane is positioned at around the induction electrode isolator, and therebetween forms a coupling capacitance;
One patterned layer is formed at the surface of substrate, and it has more than one button pattern, and each button pattern is corresponding with the induction electrode of substrate bottom surface respectively, supplies the position of each induction electrode of identification;
Further, the outside of the induction electrode on this substrate surface and the bottom surface coats and is formed with a protective seam.
Further, this patterned layer is made up of a plurality of button patterns, and each button pattern is formed on the protective seam of substrate surface.
Further, each button pattern of this patterned layer is formed on the substrate with mode of printing, but except pattern also added text, symbol, to represent corresponding keypress function.
The capacitance type touch control keys panel that utilizes aforementioned components to form; When finger is not touched the button pattern of substrate surface, former existence one coupling capacitance of the induction electrode of substrate bottom surface and ground plane, and when finger touches button pattern; Can make induction electrode produce an inductance capacitance value; This inductance capacitance value adds that coupling capacitance increases the total capacitance value of induction electrode, thus, can supply to read this induction electrode by the information of touch-control with the controller scanning that is connected the socket connection; Because induction electrode is formed at the bottom surface of substrate, and user's operational zone is to be positioned at substrate surface, needn't worry to damage induction electrode when therefore operating; As for the button pattern on the patterned layer is the position that supplies the identification induction electrode, and it can guide the induction electrode on user's touch-control correspondence position exactly.

10 substrates, 11 induction electrodes
12 ground planes 13 connect socket
14 leads, 15 patterned layer
16 button patterns, 17 protective seams.
Embodiment
About first preferred embodiment of the utility model, see also shown in Figure 1ly, it comprises:
One substrate 10; Its bottom surface is formed with the ground plane 12, that more than one induction electrode 11, is positioned at around the induction electrode 11 isolator and connects socket 13 and be connected induction electrode 11 and the lead that is connected socket 13 14 more than one; Wherein ground plane 12 is positioned at around the induction electrode 11 isolator, and therebetween forms a coupling capacitance; In present embodiment, substrate 10 bottom surfaces are formed with a plurality of induction electrodes 11, and it is circular that each induction electrode 11 is respectively; Induction electrode 11 outsides on substrate 10 surfaces and the bottom surface coat and are formed with a protective seam 17 again;
One patterned layer 15; Please additional reference shown in Figure 2, it has more than one button pattern 16, in the present embodiment; This patterned layer 15 is made up of a plurality of button patterns 16; Each button pattern 16 is formed on the protective seam 17 on substrate 10 surfaces, and corresponding with the induction electrode 11 of substrate 10 bottom surfaces respectively, supplies the position of each induction electrode 11 of identification; In present embodiment, each button pattern 16 can be formed on the substrate 10 by mode of printing again, but except pattern also added text, symbol, to represent corresponding keypress function.
When finger is not touched the button pattern 16 on substrate 10 surfaces; There is a coupling capacitance between the induction electrode 11 of substrate 10 bottom surfaces and the ground plane 12; And when finger touches wherein during a button pattern 16; Because human body forms a loop over the ground, make to point to can be considered an electrode and produce an inductance capacitance value that this inductance capacitance value adds coupling capacitance originally with this induction electrode 11; And the total capacitance value between this induction electrode 11 and the ground plane 12 is increased, can supply thus to read this induction electrode 11 by the information of touch-control with the controller scanning that is connected socket 13 connections; Please refer to shown in Figure 3ly, because induction electrode 11 is formed at the bottom surface of substrate 10, and user's operational zone is to be positioned at substrate 10 surfaces, needn't worry to damage induction electrode 11 when therefore operating; As for the button pattern 16 on the patterned layer 15 are the positions that supply identification induction electrode 11, and it can guide the induction electrode 11 on user's touch-control correspondence position exactly.
User mode about the preferred embodiment of the utility model; See also shown in Figure 4; Be the menu processing district that the utility model is arranged at the screen below, because this capacitance type touch control keys panel is via protective seam 17 sealings, when screen is arranged at the not good zone of working environment; Point the place of frequent touching like humidity height or user, this capacitance type touch control keys panel does not receive aqueous vapor erosion or scratch by substrate 10 and protective seam 17 protection induction electrodes 11 and damages.
Another user mode about the preferred embodiment of the utility model; Seeing also shown in Figure 5ly, is the inside that the utility model is arranged at keyboard, in order to replace traditional mechanical formula button and circuit board; Because this capacitance type touch control keys plate thickness is thin than traditional mechanical formula keyboard; That can reduce the mechanical type button is provided with volume and weight, again the user to point contact area be the patterned layer 15 on substrate 10 surfaces, need worry can not damage induction electrode 11 when therefore operating.
Know that by aforementioned this capacitance type touch control keys panel has the characteristic of capacitance type touch-control panel, can avoid induction electrode 11 to suffer user's scratch again and the problem damaged.
