Description
Technical field
The patterning transparent conductive film of the relevant a kind of transparency carrier of the utility model aims to provide a kind of patterning transparent conductive film that can be applicable in the contact panel.
Background technology
Press, in recent years, the man-computer interface of thoughts and feelings formula, as: contact panel (Touch Panel), be widely used to electronic product miscellaneous, as: GPS (GPS), PDA(Personal Digital Assistant), mobile phone (cellular phone) and palmtop computer (Hand-held PC) etc., to replace traditional input media (as: keyboard and mouse etc.), significantly change in this design, not only promoted the man-computer interface compatibility of these electronic installations,, and vacateed more spaces more because of having omitted traditional input media, for large-scale display panel is installed, make things convenient for the user to browse data.
Traditionally, the employed touch technology of contact panel, difference according to its start principle, though can be divided into optical profile type, the ultrasonic formula, infrared-type, condenser type and resistance-type etc. several, only, at present still with the touch technology of resistance-type (Film on Glass), be widely used in most on the various end product, consulting shown in Figure 1 is traditional resistor formula contact panel, this kind contact panel adopts the detecting voltage mode to respond to, comprise the transparent conductive film (ITOFilm) 20 that a transparent conducting glass (ITOGlass) 10 and that is coated with tin indium oxide (ITO) conductive layer 101 is made by tin indium oxide (ITO) material 201, wherein on this transparent conducting glass 10 and the transparent conductive film 20, utilize screen printing technology, conductive silver glue (silver paste) is printed the position at contiguous its edge to this transparent conducting glass 10 respectively and the transparent conductive film 20 respectively, to form required circuit 11 and 21, succeed, again in respectively forming an insulation course 12 in regular turn on this circuit 11 and 21,22 and one following layer 13,23, and insert a plurality of spaced spaced points (dotspacer) 30 at this transparent conducting glass 10 and 20 of transparent conductive films, and after on this circuit 11 and 21 respectively, inserting flexible flat cable 111 and 211, get final product respectively this following layer 13 of mat, 23, this transparent conducting glass 10 and transparent conductive film 20 involutions are integral, produce required contact panel.
When the user directly touches a certain position on this transparent conductive film 20 with finger, pen or other medium, the transparent conductive film 20 of this position will form conducting on electric with this transparent conducting glass 10, and in correspondence position generation potential difference (PD), the control circuit of circuit board is promptly according to by these flexible flat cables 111 and 211 poor from these circuits 11 and 21 different potentials that sensed, further calculate the coordinate figure at touch location place, and on the respective coordinates position of this contact panel display highlighting.
General speech, traditional electric resistance touch-control panel is according to the different wiring mode of its circuit, can be divided into different distribution patterns such as four lines (4 Wire), five lines or six lines again, now be example with the five-line contact panel, consult shown in Figure 2ly that its contact panel is at four circuits of X and Y direction, all be laid in contiguous its periphery on the transparency conducting layer of glass substrate, then only lay a circuit on its transparent conductive film, be used for detecting the magnitude of voltage of (sampling) X and Y-axis, amount to 5 circuits.When the user bumps on this contact panel P point position with finger or style of writing, control circuit will be to the power supply of 5 volts of two circuits 1 on the transparency conducting layer of this glass substrate and 2 supplies, and make other two-lines road 4 and 5 is in ground state (ground, be that voltage equals zero), at this moment, touch position changes because of impedance, to produce pressure drop, make circuit on this transparent conductive film can be sampled to the magnitude of voltage of Vpy, otherwise, when the power supply of control circuit to 5 volts of two circuits 2 on the transparency conducting layer of this glass substrate and 4 supplies, and when making other two-lines road 1 and 5 be in ground state (ground, promptly voltage equals zero), the circuit on this transparent conductive film will be sampled to the magnitude of voltage of Vpx, after the calculating comparison of the magnitude of voltage of these Vpx and Vpy via control circuit, can learn the coordinate position at this P point place rapidly.
The method of making transparent conducting glass at present is a main flow with traditional gold-tinted photolithography techniques still, as shown in Figure 3, it makes flow process is sputter layer of transparent conductive layer 15 on a clear glass 14, re-lay a photoresist layer 91 on this transparency conducting layer 15, secondly drawing one has the light shield 92 of pattern 921 to be arranged at this photoresist layer 91 tops, shine via ultraviolet ray, chemical change does not take place in the photoresist layer 91 that is covered by pattern 921, the photoresist layer 91 that utilizes developer solution will produce chemical change cleans to be removed, and the transparency conducting layer 15 that makes part that pattern 921 is not set exposes outside, also make the pattern 921 on the light shield 92 transfer on this photoresist layer 91, the exposed transparency conducting layer 15 of etching again, at last this photoresist layer 91 is removed fully, promptly formed transparent conducting glass 10 with patterning.
The not only required apparatus expensive of above-mentioned yellow light lithography method for making, the composition and the developer solution of used photoresist layer 91 are harmful chemical solution, not only the operating personnel's at scene health are caused to seriously influence, and also environmental ecology are caused serious pollution.When removing the photoresist layer 91 that produces chemical change,, can make the pattern 921 that is needed on this photoresist layer 91 break away from or decompose, reduce and produce yield as the soaking and washing overlong time with developer solution.
The utility model content
In view of this, the technical matters that the utility model solved is to provide a kind of transparency carrier especially to can be applicable to patterning transparent conductive film in the contact panel.
Take off purpose on reaching, transparency carrier of the present utility model is provided with the patterning transparent conductive film, this transparent conductive film is by the pattern area that is formed with hollow out in the reusable shielding, and be arranged at this shielding on the transparency carrier and carry out sputter or evaporation, the material that will conduct electricity evenly adheres to and is deposited on the transparency carrier, and forms required patterning transparent conductive film.
The beneficial effects of the utility model are, not only processing procedure is easy and the utility model processing procedure in do not need to utilize liquid handling fully, and be dry process, can improve to practise has the disappearance of utilizing the gold-tinted processing procedure can produce the waste liquid serious environment pollution.
