Description
Technical field
The present invention relates to a kind of manufacture method of touch induction device, relate in particular to a kind of capacitance touch screen manufacture method.
Background technology
In recent years, along with the fast development and the application of infotech, radio mobile communication and information household appliances, people grow with each passing day to the dependence of electronic product.In order to reach more convenient, lighter and handyizatioier of volume and more humane purpose, many information products by traditional keyboard or mouse as input media, change into and use the touch-screen that being arranged on before the display screen as input media.Existing touch-screen is broadly divided into types such as condenser type, resistance-type, photosensitizing type.Capacitance touch screen has been widely applied in each electronic product, for example mobile phone, mp4, POS terminal etc.The characteristics of capacitance touch screen are that transmitance height and touch are exerted pressure and needn't be exerted oneself, and can resist abominable external environment, for example: water, temperature variation, so humidity is long service life, survey when can also realize a plurality of touch point during work, manipulate humanized.
Existing capacitance touch screen generally comprises contact panel (overlay), glass substrate and sensing electrode layer; The sensing electrode layer is arranged on the glass substrate, the sensing electrode layer comprises a plurality of first sensing electrode and a plurality of second sensing electrodes that extend along second direction that extend along first direction, the interlaced formation induction arrays of first sensing electrode and second sensing electrode; Electrically do not connect mutually between each first sensing electrode, electrically do not connect mutually between each second sensing electrode, electrically be not connected between first sensing electrode and second sensing electrode.First sensing electrode and second sensing electrode form through graphical as indium tin oxide films generally by nesa coating.
When the user contacted contact panel with finger, first sensing electrode at contact origination point place, the electric capacity at the second sensing electrode place changed, and by electric circuit inspection, just can judge the generation of touch and the coordinate of contact origination point.
Above-mentioned capacitance touch screen is the hard capacitance touch screen, and a developing direction of capacitance touch screen is flexible capacitance touch screen, flexible capacitance touch screen has advantage flexible, that be difficult for breaking, has reliability preferably, and can with flexible display, as flexible organic light emission (OLED) display combinations.
Flexible capacitance touch screen generally comprises overlay, tablet and auxiliary rete (as guarded electrode layer, optical compensating layer and interior anti-reflecting layer etc.), the superimposed in regular turn from outside to inside setting of above-mentioned each layer, and being bonded sandwich construction by adhesive-layer, the material of each layer is flexible material.
The overlay of above-mentioned flexible capacitance touch screen plays capacitive isolation, protection and effect attractive in appearance to flexible capacitance touch screen; its main body is outer supporting layer; can be general printing opacity flexible membrane, also can be circular polarizing disk---adopt circular polarizing disk to have the catoptrical effect of the touch-screen internal reflection surface of elimination.Light-proof material coverage layer that make, the part hollow out is posted in outer supporting layer inboard, it act as the touch screen portion zone, especially cover the neighboring area, form the coverage zone at non-hollow out place, be used for hiding touch-screen internal wiring and other influence position attractive in appearance, form non-coverage zone at the hollow out place, be used to keep the printing opacity of the optical device such as display of institute's combination.Outer supporting layer and the general patterned layer that also inserts and puts certain artistic pattern by the mode of printing or pad pasting of coverage interlayer are as forming trade mark or marking keys, to satisfy the demand of touch-screen outward appearance.
Tablet is used for the location sensitive of flexible capacitance touch screen and exports corresponding electric signal.Generally speaking, two sides at the interior supporting layer of being made by flexible material is coated with conducting film, the conducting film that wherein is in lateral surface is patterned into first sensing electrode, the conducting film that is in medial surface is patterned into second sensing electrode, and interior supporting layer itself then forms the insulation course between first sensing electrode and second sensing electrode.Interior supporting layer also can have the extension, first sensing electrode and second sensing electrode go between by the periphery that is arranged on the neighboring area and are connected to external-connected port by the extension, thereby the extension has formed flexible external line, and the end of extension constitutes external connection end.
Above-mentioned first sensing electrode and second sensing electrode are arranged in the sensing region of tablet, also are provided with the periphery lead-in wire at first sensing electrode and the second sensing electrode periphery and elongated area part.
Overlay and tablet have constituted the main body of touch-screen, auxiliary rete then is used to improve the interference free performance and the optical property of touch-screen, as increasing one deck guarded electrode layer and corresponding supporting layer, by its ground connection being masked undesired signal from the bottom, and supporting layer adopts under the situation of circular polarizing disk outside, increase the anisotropy optics layer of compensation of one deck by certain design, as-1/4 wavelength compensation film, then can offset or adjust the phase delay of circular polarizing disk, make the light that sees through touch-screen have desirable polarization state.And supporting layer does not adopt under the situation of circular polarizing disk outside, in order to reduce the reflection of inside surface, can be in the most inboard attaching one of touch-screen anti-reflecting layer, reduce the reflection of inside surface by its refractive index match.
General certain hard, the thickness of adopting of above-mentioned outer supporting layer, interior supporting layer and other supporting layer, optical isotropy and the not printing opacity organic material making of scattered light are as selecting polyethylene terephthalate (PET), triacetate fiber polymkeric substance such as (TAC); Adhesive-layer is the mucilage materials that optical isotropy does not have scattered light character, as acryl resin; Electrode film is a transparent conductive material, generally adopts tin indium oxide (ITO), aluminum zinc oxide (ZAO); Cover layer and can adopt metal film, as the aluminium film; Patterned layer can adopt printing ink printing, perhaps adopts the film of any material to attach.
In actual design, above-mentioned each layer especially covered each above layer of layer, can be designed to comprise various touch-screen appearance profiles such as perforate.
For the hard capacitance touch screen, its manufacture method generally is: adopt various materials to carry out repeatedly plated film, coating and technology such as graphical on glass substrate, form first sensing electrode, second sensing electrode, cover retes such as layer, patterned layer and screen layer, final tablet and the overlay of forming, and then tablet and overlay is bonding, form the hard capacitance touch screen.Since on the monolithic glass substrate, carry out repeatedly plated film, coating and technology such as graphical, its manufacturing process complexity, and the product yield is lower.If the manufacture method of hard capacitance touch screen is used for the manufacturing of flexible capacitance touch screen, unavoidably on one deck flexible membrane layer, carry out repeatedly plated film, coating and technology such as graphical, its difficulty is bigger, and technology is complicated more, and the product yield is lower.Thereby the manufacture method of hard capacitance touch screen is not suitable for the manufacturing of flexible capacitance touch screen, does not have the manufacture method that a cover is practical, can produce flexible capacitance touch screen in batches so far yet.
