Abstract
The invention provides a manufacturing method for a capacitive type touch screen, relating to the technical field of the capacitive type touch screen. The manufacturing method provided by the invention comprises the steps of panel preparation, sensor preparation and lead wire preparation. The sensor preparation step comprises the following steps of: 1) transferring a transparent conductive layer and a light resistance layer on a panel in a transfer printing manner; and 2) preparing a sensor panel by exposing, developing, etching and de-molding. The lead wire preparation step comprises the following steps of: pre-setting patterns of a lead wire; printing the pre-set patterns of the lead wire by an ink-jet printer on a prepared belt sensor panel; and curing. With the adoption of the manufacturing method, the purposes of less technique process, convenience in controlling a product quality, and high product yield can be realized.
Description
Technical field
The present invention relates to the technical field making capacitive touch screen.
Background technology
Current capacitive touch screen needs through following operation when making, first through panel preparation, then prepares sensor and preparation lead-in wire, if preparation sensor main plating transparency conducting layer on panel, through adding photoresist layer post-exposure, development after etching, and demoulding; As long as preparation lead-in wire first plated film on the sensor prepared, then adds photoresist layer post-exposure, development after etching, and demoulding.Traditional handicraft technological process is many, equipment investment large, quality control difficulty is large, product percent of pass is low, demand of human resources is large, causes the price of capacitive touch screen to remain high for a long time, is unfavorable for that it is popularized rapidly.
Summary of the invention
It is few that the object of the invention is to provide a kind of technological process, is convenient to control product quality, the capacitive touch screen preparation method that product percent of pass is high.
A kind of method for making of capacitive touch screen, comprise panel preparation, prepare sensor, preparation goes between, described sensor of preparing comprises the steps: 1) in the mode of trans-printing, transparency conducting layer and photoresist layer are transferred on panel, 2) obtain sensor panel by exposure, development, etching, demoulding; Described preparation lead-in wire comprises the steps: pre-set lead pattern, and pre-set lead pattern is printed on the belt sensor panel for preparing by ink-jet printer, and is cured.
Ink-jet printer of the present invention uses Nano Silver ink special.
The present invention adopts technique scheme, and compared with prior art tool has the following advantages:
1, adapt to wide: not only to transfer printing in PC plate, PMMA plate and composite plate, can also can shift on tempered glass, PET panel; It panel can be light face.ICON can also be printed in advance; Panel can be plane, can also be the on-plane surface such as cylinder, formed in mould curved surface;
2, transfer materials is various: not only can transfer printing ITO conductive layer, can also transfer printing nano-silver conductive layer, photoresist layer, or their combination;
3, stable and controllable for quality: material to be transferred is by specialized vendor's batch preparation on request, stable and controllable for quality.
4, equipment is simple, and versatility is good, and production efficiency is high: transfer apparatus is simple, reduces investment; Primary transfer, can prepare multilayer (as: conductive layer+photoresist layer), production efficiency is high; Lead-in wire prints only needs a special ink-jet printer, eliminates the making of a large amount of half tone, general convenient; Greatly enhance productivity.
5, operation simplifies, and reduces costs: relative to former flow process, this technological process simplifies serigraphy, saves man-hour and personnel, reduces the unit cost of product, promotes capacitance plate competitive power commercially, is conducive to capacitance plate and popularizes fast.
