Description
Technical field
The present invention relates to touch screen, be specifically related to a kind of recessive cover plate touch screen and production method thereof.
Background technology
Touch screen is a kind of inductive arrangement receiving the input signals such as contact, is typically applied in combination with display screen,
When contacting the graphic button on screen, the haptic feedback system on screen can drive various companies according to the formula of preprogramming
Knot device, is substituted for mechanical push button panel, and produces lively visual and sound effects by display picture.Touch screen is made
For a kind of up-to-date computer input apparatus, it is man-machine interaction mode the simplest, convenient, a kind of.It give
Multimedia, with brand-new looks, is extremely attractive brand-new multimedia interactive equipment.Be widely used in public information inquiry,
Leader's office, Industry Control, military commanding, electronic game, choosing song or selecting dish, multimedia teaching etc..
There is the features such as support multiple point touching, high sensitivity and pinpoint accuracy, therefore condenser type due to capacitive touch screen
Touch screen obtains extensively application in multi-media display device.General capacitance touch screen is to combine with liquid crystal display to answer
, capacitance touch screen is fitted in display screen surface, generally also can add one piece of cover plate again at capacitance touch screen surfaces when application,
One is protective effect, and two is to stamp black ink in cover plate surrounding, covers the cabling that capacitance touch screen surrounding manifests, to ensure
Whole product attractive in appearance.And along with consumer's portability requirements the highest to electronic product, therefore thin to display module
Shape, lightweight requirements are the most following.
At present, a kind of recessive cover plate touch screen effectively improves this problem, and it is traditional cover plate and touch screen to be sensed
Device is incorporated in layer glass, based on this design, can save one piece of cover plate.Its processing technology is the most on the glass substrate
