Description

Contact panel

Technical field

A contact panel, espespecially a kind ofly reduces the quantity of wire and avoids interference in mechanism and contact panel that signal is shielded.

Background technology

Along with the development of contact panel technology in recent years, there is now the portable electronic devices of Presentation Function, as all changing, Smartphone, panel computer etc. adopt contact panel to replace the mechanical key that tradition takes up space.

Take a broad view of in existing contact panel, more often be used in the capacitance type touch-control panel that mostly is of portable electronic devices, and general capacitive contact panel, this contact panel arranges a tin indium oxide (ITO) layer on a transparency carrier bottom surface, and bottom surface periphery is as a wiring region, on this indium tin oxide layer, be formed with a plurality of electrodes, and a plurality of wires are set on this wiring region are electrically connected to the plurality of electrode respectively, and because above-mentioned wire is nontransparent thing, therefore when the manufacturer of making electronic installation takes above-mentioned contact panel, must be coated with an ink layer in a fender bottom peripheral edge again, and in the end face of above-mentioned contact panel, one adhered layer and bonding with this fender is set, make the wiring region of the corresponding contact panel of this fender bottom surface ink layer, so that the wire in contact panel wiring region is covered, and the use of ink layer and adhered layer causes the problem of processing procedure and material cost except meeting to the manufacturing plant of electronic installation, also can make the integral thickness of electronic installation increase, cannot meet the compact demand of portable electronic devices, therefore the shortcoming such as integral thickness certainly will need to improve to some extent.

Moreover, conventional condenser contact panel is because solve known problem, the electrode of transverse axis and the longitudinal axis is arranged on same plane, by fine and closely woven wire laying mode, the electrode of diaxon is set again, so as to reducing integral thickness, but the electrode of diaxon easily produces and disturbs at a distance of too near, moreover, easily because distance is crossed and then generation is interfered or causes the shortcomings such as electric pole short circuit or signal interference, therefore known technology has following shortcoming:

1 manufacturing cost is higher;

2 easily cause interference;

3 easily produce signal disturbs.

Summary of the invention

For this reason, for solving the shortcoming of above-mentioned known technology, fundamental purpose of the present invention, is to provide a kind of electrode of avoiding and mutually interferes or the contact panel of signal phase mutual interference.

For achieving the above object, the invention provides a kind of contact panel, comprise: a substrate, a shielding layer, one first electrode layer, one first insulation course, a second electrode lay, a conductor layer, one second insulation course; This substrate has a Touch Zone and a non-Touch Zone, and this non-Touch Zone is positioned at the outside of this Touch Zone; Described shielding layer is located at this non-Touch Zone; This first electrode layer is located at this Touch Zone, and part extends to this non-Touch Zone; This first insulation course covers aforementioned the first electrode layer one side; Described the second electrode lay is located at the opposite side of contrary this first electrode layer of this insulation course, and this Touch Zone relatively, and part extends to this non-Touch Zone; Described conductor layer is located at this non-Touch Zone, corresponding with this shielding layer, and is electrically connected with aforementioned first and second electrode layer; This second insulation course is covered in aforementioned the second electrode lay and this conductor layer, and the setting by structure of the present invention not only can prevent interelectrode mutual interference, more can avoid producing signal and disturb.
