Description

A kind of peelable circuit protection structure of touch screen

Technical field

The utility model touch screen circuitry protection technique field, more particularly to a kind of peelable circuit protection knot of touch screen Structure.

Background technology

Touch screen is a kind of input equipment for significantly improving man machine operation interface, is had the advantages that intuitive, simple, quick. Touch screen has been obtained for being widely applied in many electronic products, such as mobile phone, PDA, multimedia, public information inquiry system System etc..In the past, various types of touch screens continuously emerge, including resistance-type, condenser type, infrared and surface acoustic wave touch screen.

Generally, capacitive touch screen is the pole by the use of the transparent conductive film in touch screen as capacitance, the hand of human body Refer to another pole as capacitance, when finger approaches or contacts touch screen surface, finger is coupled with touch screen, forms one newly Capacitance, the controller of touch screen calculates the position coordinates (X, Y) of contact point, finally, host by measuring the variation of capacitance Corresponding event is explained and performed to the position coordinates (X, Y) provided according to controller.Past, due to structure and the limit of driving cost Various shortcomings such as system and touch-control distortion, the operation strategies of capacitive touch screen are very narrow, and resistive touch screen is city Most commonly used touch screen technology in.Resistive touch screen is that a kind of acted on using pressure causes upper and lower conductive layer Contact causes the electric signal of system to change to realize input function.In the recent period, it is continuous due to structure and signal processing technology It improves, capacitive touch screen gradually rises.In these novel capacitive touch screens, because the flexibility for eliminating touch screens is led Electrolemma and labyrinth employ different touch control manners, show more good performance, for example, without machinery fortune in screen Dynamic wear problem, even and if it is simple in structure, light transmittance is high, the linearity is good, dust-proof, fire prevention, it is scratch resistant, in worst environment Also there is stable performance etc..The advantages of another aspect of capacitive touch screen is that it can realize multi-touch function, even if User can be carried out at the same time the input of multiple point touching signal by it, realize that multiple spot operates to complete specifically to act simultaneously, such as The function of amplification, diminution, rotation etc..

In touch screen manufacturing process, also need to complete to manufacture by multiple working procedure after circuit is printed, but In the prior art, circuit friction damage is easy to cause in follow-up manufacture, situations such as open circuit occurs, to the protecting effect of circuit not It is good.

Utility model content

Touch screen body is played using strippable protection blue glue to solve the above problems, the utility model offer is a kind of Protecting effect can play protecting effect to conducting wire and stealthy induction line simultaneously, and avoid causes in process Electric line and stealthy induction line are damaged, and protecting effect is good, and peelable after the completion of following process, does not influence to use, and protects Protect the good peelable circuit protection structure of touch screen of effect.

Technical solution is used by the utility model：A kind of peelable circuit protection structure of touch screen, including touch screen Ontology, the touch screen body include toughened glass layer, are set to the laminated touch sensible of tempered glass successively from top to bottom Layer, several stealthy induction lines and the conducting wire being connected with stealthy induction line are printed in the touch sensitive layer, it is described Circuit protecting layer is coated in conducting wire；The touch screen body is coated with strippable protection oil in conducting wire one side Ink, the protection ink thickness range is in 0.02mm~0.2mm.
