Description
Technical field
The invention belongs to the electronic product components manufacture method, particularly a kind of method of utilizing the metal coating technology on contact panel, to lay automatically controlled circuit.
Background technology
In recent years, thoughts and feelings formula man-computer interface, as contact panel (Torch Panel), be widely used in the electronic product miscellaneous, as global positioning system (GPS), personal digital assistant (PDA), mobile phone (cellular phone) and palmtop computer (Hand-held PC) etc., to replace traditional input unit, as keyboard and mouse.Significantly change in this design has not only promoted the man-computer interface compatibility of electronic installation, more vacates more spaces because of having omitted traditional input unit, for large-scale display floater is installed, makes things convenient for the user to browse data.
Traditionally, the employed touch technology of contact panel, according to the difference of its operating principle, though can be divided into optical profile type, ultrasonic waves formula, infrared-type, condenser type and resistance-type etc. several.Only, still with the touch technology of resistance-type (Filmon Glass), be widely used in most on the various end product at present.
As shown in Figure 1, traditional resistor formula contact panel adopts the detecting voltage mode to respond to, the transparent conductive film (ITO Film) that it comprises the transparent conducting glass (ITO Glass) 10 of coating tin indium oxide (ITO) conductive layer, made by tin indium oxide (ITO) material and be formed at electro-conductive glass 10 and film 10 on the automatically controlled circuit 11,21 of contiguous its marginal position.
Automatically controlled circuit 11,21 prints conductive silver glue (silver paste) respectively for utilizing screen printing technology that the neighboring edge position forms to each glass 10 and the film 20.
Form insulating barrier 12,22 and following layer 13,23 on the automatically controlled circuit 11,21 in regular turn, and insert several spaced spaced points (dot spacer) 30 at transparent conducting glass 10 and 20 of films, and on each automatically controlled circuit 11,21, insert flexible flat cable 111,211, can borrow each following layer 13,23 that transparent conducting glass 10 and film 20 involutions are integral, produce required contact panel.
When the user directly touches on the transparent conductive film 20 a certain position with finger, pen or other media, the transparent conductive film 20 of this position will form the electric conducting of going up with transparent conducting glass 10, and in correspondence position generation potential difference, the control circuit of circuit board is promptly poor according to sensing different potentials by flexible flat cable 111,211 from automatically controlled circuit 11,21, further calculate the coordinate values at touch location place, and on contact panel respective seat cursor position, show vernier.
Generally speaking, traditional electric resistance touch-control panel can be divided into different distribution forms such as four lines (4Wire), five lines or six lines according to the different wiring mode of its automatically controlled circuit.Be example now with the five-line contact panel, as shown in Figure 2, its contact panel all is laid on the transparency conducting layer of glass substrate 10 and contiguous its periphery at four automatically controlled circuits 11 of X and Y direction, then only lay an automatically controlled circuit 21 on its transparent conductive film 20, be used for detecting the magnitude of voltage of (sampling) X and Y-axis, amount to five automatically controlled circuits.When the user touches on the control panel during P point position with finger or style of writing, control circuit 21 will be to two automatically controlled circuits 1 on the transparency conducting layer of glass substrate 10 and 5 volts of power supplys of 2 supplies, and make other two automatically controlled circuits 4 and 5 are in ground state (ground, be that voltage equals zero), at this moment, touch position changes because of impedance, makes automatically controlled circuit 21 on the transparent conductive film 20 can be sampled to the magnitude of voltage of Vpy with producing pressure drop; Otherwise, when control circuit to the transparency conducting layer of glass substrate 10 on the power supply of 5 volts of two automatically controlled circuits 4 or 5 supplies, and make other two automatically controlled circuits 1 and 2 are in ground state (ground, be that voltage equals zero) time, automatically controlled circuit 21 on the transparent conductive film 20 will be sampled to the magnitude of voltage of Vpx, after the calculating comparison of the magnitude of voltage of Vpx and Vpy via control circuit, can learn P point place coordinate position rapidly.
