Description
[technical field]
The present invention relates to a kind of touch screen, more particularly to a kind of touch screen based on stylus and its transparent conductive film,
Touch-control mobile terminal.
[background technique]
With the development of electronic technology, in the early 1990s, there is a kind of new human computer interaction's skill
Art --- touch screen technology.As long as lightly touched using this technology user with finger icon on electronic product display screen or
Text can be achieved with thus getting rid of keyboard and mouse action to host service function, keep human-computer interaction more simple and direct.Cause
This, touch screen technology has become the input equipment of current the simplest man-machine communication.It imparts multimedia with brand-new looks,
It is extremely attractive completely new multimedia interactive equipment.As laptop, mobile phone, tablet computer etc. are to touch screen demand
Increasingly increase, it is some to be suitable for the touch screen that volume production, reaction speed are fast, save space, are easy to exchange and continue to bring out in the market.
Application range of the touch screen in China is boundless, mainly the inquiry of public information: as telecommunication bureau, the tax bureau,
The service inquiry of the departments such as bank, electric power；The information in city street corner is inquired；Museum, the Art Museum data check；Airport station
Flight, train query；Furthermore applied to leader's office, Industry Control, military commanding, electronic game, choosing song or selecting dish, multimedia
Teaching, real estate presell, air ticket/ticket pre-sale etc..As city is developed with computer network to information-based direction in state's people's livelihood
Infiltration in work, information are inquired all by touch screen --- occurs in the form of display content is tangibly.The basic principle of touch screen is
The touch screen for being mounted on display front end is touched with finger or other objects, the position touched (with coordinate form) is by touch screen
Controller detection, and CPU is sent to by interface (such as RS-232 serial port), so that it is determined that the information of input.
Touch-screen system generally comprises two parts: the controller and touch detecting apparatus of touch screen.The control of touch screen
The main function of device is touch information to be received from touch detecting apparatus, and be converted into contact coordinate, then give CPU, it
The order that CPU is sent can be received simultaneously and is executed.Touch detecting apparatus is typically mounted at the front end of display, main function
It is to detect the touch location of user, and send touch screen controller to, and touch detecting apparatus is typically provided fine conductive pattern
Case.
Conductive pattern above touch detecting apparatus directly influences touch precision, for traditional touch screen, uses finger
It touches, the diameter H of finger touch area generally has 8-9 millimeters, as shown in Figure 1.
So the electrode gap of conductive pattern is 4.5 millimeters of touchings that can detect finger for traditional touch screen
Position is touched, as the development and application of touch technology is constantly promoted, requirement of the user to touch accuracy is continuously improved, and starts
Replaced with stylus finger to capacitive touch screen carry out touch-control (because stylus written diameter be less than finger diameter,
The more accurate touch-control of a finger may be implemented).Stylus according to its whether can emit signal be segmented into active stylus and
Passive type stylus.
For active stylus: being provided with circuit in pen, when nib contacts touch screen, active stylus can emit
Signal judges that position of touch realizes that touch-control is grasped by receiving the signal that active stylus emits to touch screen, touch screen out
Make.Match it can be seen that active stylus also needs to configure on touch screen during use with nib transmitting signal
Reception system.
For passive type stylus: nib is conductor, and the penholder for connecting nib can be conductive material, be also possible to non-lead
Electric material is not provided with any circuit in passive type stylus, replaces finger to carry out touch screen with the small nib of radius ratio finger
Touching, to realize more accurate operation.For cost, the cost of passive type stylus will be far smaller than active stylus
Cost.Therefore, high speed is universal to the application that touch screen is operated for passive type stylus.
The use of passive type stylus match traditional touch screen conductive pattern precision can not, such as Fig. 2 institute
Show, tetra- positions touch-control A, B, C, D is distinguished using stylus, preferably the result is that tetra- coordinates of A, B, C, D can be obtained, still
Two positions A, B can only allow the same induction electrode to generate touching signals as can be seen from Figure 2, and two positions C, D can only also allow
The same induction electrode generates signal, it can thus be appreciated that tetra- positions above-mentioned A, B, C, D can only obtain 2 using stylus is touch
Coordinate, touch accuracy are undesirable.
