Abstract
Discrete plural resistance elements are printed or coated on perimeter of electro-conductive film surface of the inductor. Gap components with different size are formed between each row of resistor element. Multiple insulator components of different size are etched on inner side of each row of resistor element group. Gap components of different size are formed between each adjacent insulator components. Thus, resistance regions are formed based on gap components. Each small area with voltage gradient or electric field gradient is formed on the periphery of each independent resistor element and each insulator component in order to cancel out potential difference between each corner. Further, straight type X, Y axial equipotential line can be obtained.
Description
Affiliated technical field
The present invention relates to a kind of method and device of its detection rightness of increase contact-controllable detector, refer to especially a kind of when on Trackpad, doing the contact, on detector, produce more accurate X, Y-axis to the equipotential line signal coordinates.
Background technology
See also shown in the accompanying drawing 7, known contact-controllable detector is on the surface of transparent or semitransparent substrate A, evenly the thin conductive film B (being the ITO layer) of coated one deck; One rectangular conductive material C (as silver slurry line) is printed in the rim all around of conductive film B, form linear pattern, four lead W1, W2, W3, W4 are connected in four corners of conductive material C, and therein two corner C2, C4 impose suitable to voltage, two corner C1, C3 impose on the voltage of OV in addition, are form electric field on conductive film B surface; The impedance (or electric conductivity) of conductive material C at this moment just, the homogeneity that will depend on conductive film B surface field, conductive material C for example, if be high conductivity, all electric currents conductive material C that can flow through then, only little part can flow to conductive film B (1TO layer) intermediate surface zone, make the contact region that is subjected to of conductive film B be difficult to detecting because of voltage is too faint, so at the defined X of conductive film B surface field, Y uranium to equipotential line S be sweeping arc, conductive bit S such as this arc are distributed on the surface contact zone of conductive film B, when this zone is subjected to the contact, the X that is produced, Y-axis to voltage signal just incorrect, so it is just incorrect to be presented on the position that slider position on the display and contact click.Given this shortcoming, general improved mode is the equipment that sees through the outside, corrects equipotential line as potential divider or software, and the pressure-wire S such as arc of its X, Y-axis can be straightened.But in fact must increase the equipotential line S that potential divider or soft design improve arc and will increase suitable cost.
So, the inventor once tested conductive material C was substituted with the low electric conductivity material of higher resistance, this design still produces some shortcomings, promptly, always be higher than the terminal voltage of four corner C1, C2, C3, C4 between the voltage of every adjacent corner (C3, C1) zone line or corner C1-C2 zone line or corner C2-C3 zone line or corner C3-C4 zone line; With regard to the equipotential line of electric field, be in certain some zone or be non-rectilinear and be crooked, so the inaccurate situation of voltage coordinate signal that some zone, conductive film B surface was produced when being subjected to the contact takes place equally.
At above-mentioned defective, the 4661 No. 655 patent case of US, improved with regard to the arc equipotential line that detector surface produced, it is to utilize electrode material, in single discontinuous mode of not piling up, be printed on the lip-deep rim all around of conductive film, make every row's electrode material increase impedance, on electrode material, increase impedance, though the compensation of part arc equipotential line slightly can be improved, but can't effectively reduce the distribution scenario of arc equipotential line, thereby the application of this patent case need rely on extra hardware and software to be revised to reach linear purpose.
No. 4797514 patent case of US, its main device is to print rectangular box-like conductive material (being resistive material) at a transparent or semitransparent substrate surface, this conductive material is continuity;
Layer of conductive film (or resistive layer) is printed in the surface of substrate, conductive material is between the lower surface of conductive film, its principal character is that the corner inner side edge is done etching around conductive film, make the insulating regions that is plural number, form the resistance electrode element between every adjacent insulating regions, when electric current is flowed through between the resistance electrode element, can be listed as plural insulating regions to each other at this, produce certain voltage gradient, this effective voltage gradient can be offseted (or compensation) voltage drop that conductive material produced, further make conductive material produce voltage drop, the equipotential line of the bending that is caused is proofreaied and correct and is straight line.
The shortcoming of this case is to be continuity at conductive material, when therefore the corner contact is transfused to appropriate voltage, the voltage drop ratio that is produced between its every adjacent corner is quite big, depending merely on single insulator region and resistance electrode, to reduce voltage drop be not enough, in other words, rim around its effective Touch Zone of inductor still can produce the equipotential line of bending arc shape greatly, and active region is needed apart from the wiring region certain distance, to avoid the offset phenomenon that bending arc shape equipotential effect causes.
