Description
Technical field
The present invention relates to touch screen, particularly relate to a kind of composite electromagnetic induction and the touch screen of capacitive sensing and making side thereof
Method.
Background technology
Capacitance-type touch screen technology is that the electric current sensing utilizing human body is operated.Capacitive touch screen is one piece four layers
Compound glass screen, the inner surface of glass screen and interlayer respectively scribble one layer of ITO, and outermost layer is a thin layer silicon soil glassivation, folder
Layer ITO coating, as work surface, four angles is drawn four electrodes, and internal layer ITO is that screen layer is to ensure good working environment.
When finger touches on the metal layer, owing to human body electric field, user and touch screen surface are formed with a coupling electric capacity, for height
Frequently for electric current, electric capacity is direct conductor, and then finger siphons away a electric current the least from contact point.This electric current is respectively from touching
Touch in the electrode on the corner of screen and flow out, and the distance of the electric current and finger to corner flowing through these four electrodes is directly proportional, control
Device processed, by the accurate calculating to these four current ratios, draws the position of touch point.
Electromagnetism screen neither belongs to capacitance plate, is also not belonging to touch screens, and is independently of a list of above two screen
Solely exist.The ultimate principle of electromagnetism screen be by time writer operating process and lower panels induction apparatus produce changes of magnetic field
Identify slip.Electromagnetic touch-control i.e. came out from 1964, and the 1970's to 1980 were used for intelligent Digitizing plate, many high-order electricity
Brain aided drawing (CAD) system seems that AutoCAD uses extensively, and Apple Computers then also serve as joining of Apple II
Standby.Electromagnetic induction touch technology is divided into 2 big classes, and one is passive type, is also called without battery pen technology；Two is active, and pen needs
Insert battery, launch signal.
Hand-writing technique: the appearance of writing pencil is contemplated to input Chinese and other spoken and written languages, and user need not learn again
The input method practising other just can input Chinese and other spoken and written languages the most easily, and this also needs to special handwriting recognition certainly
Software (former notes need not identify software).Writing pencil also has the effect of mouse simultaneously, can substitute for mouse action
Windows, it is possible to draw a picture.
The terminal of existing display substantially with keyboard with capacitance touch screen (containing EINK screen) for mainly using function, electromagnetism
The display terminal of screen mainly uses on specific handwriting functions product.
Existing electromagnetic screen needs just can carry out by pressure sensi-tive pen touching manipulation, is different from conventional, electric-resistance or capacitance touch
Screen, it is not possible to the direct touch-control of finger.Capacitance touch screen has only to touch, and produces signal without pressure；Capacitive touch
Touch screen and can support multipoint-touch-technology exactly, and unlike resistive touch screen bradykinesia and the most easy to wear.But, merit
Can be single, both cannot effectively combine, and increases product cost and Consumer's Experience can not be allowed complete simultaneously.Additionally, capacitance plate and electricity
Magnetic cup is all discretely located, and meanwhile, screen is also by independent overlapping, forms bigger thickness.
Summary of the invention
The present invention is to solve above-mentioned deficiency, it is provided that a kind of composite electromagnetic induction and the touch screen of capacitive sensing and
Manufacture method.
The above-mentioned purpose of the present invention is realized by following technical scheme: a kind of composite electromagnetic induction and capacitive sensing
Touch screen, including substrate, substrate is laid with capacitance plate membrane circuit layer and electromagnetic screen membrane circuit layer, described capacitance plate simultaneously
Membrane circuit layer and electromagnetic screen membrane circuit layer are respectively connecting to governor circuit.
Described substrate is made up of glass, plastics or thin film.
Other touch-control circuit layers can also be laid with, with capacitance plate membrane circuit layer and electromagnetic screen thin-film electro on described substrate
Road floor is combined with each other, it is achieved the input of various ways.
The manufacture method of the touch screen of a kind of composite electromagnetic induction and capacitive sensing, comprises the following steps: (1) prepares glass
Glass, plastics or thin-film sheet, as substrate；(2) on substrate, capacitance plate membrane circuit layer it is laid with；(3) lay on substrate
There is electromagnetic screen membrane circuit layer.
According to different demands by substrate capacitance circuit or electromagnetic circuit or the two receive information, the shifting that electronic pen sends simultaneously
Dynamic positional information, pressure sensitivity information etc., it is then delivered to governor circuit, is used for realizing track input, gesture control etc..Realize as drawn
Scheme, write etc. inputs and display, and analog mouse controls, button, keyboard etc..
Present invention advantage compared with prior art is: electric capacity, Electromagnetic heating are routed to same substrate by the present invention, thus
Realize the compound of the two function, effective laminating of the screen simultaneously realized by this mode, thus achieve again integral thickness
Reduce and alleviate.
