Description
[technical field]
The utility model relates to a kind of touch-screen, particularly relates to a kind of touch-screen based on pointer and nesa coating thereof, touch-control mobile terminal.
[background technology]
Along with the development of electronic technology, in early 1990s, there is a kind of new human computer interaction's technology---touch screen technology.Utilize this utilization person as long as just can realize host service function with icon or word that finger touches on electronic product display screen lightly, so just broken away from keyboard and mouse action, make man-machine interaction more simple and direct.Therefore, touch screen technology has become the easiest current man-machine communication input equipment.It has given multimedia with brand-new looks, is extremely attractive brand-new multimedia interactive equipment.Along with the increase day by day to touch-screen demand such as notebook computer, mobile phone, panel computer, some be suitable for volume production, reaction velocity fast, save space, the touch-screen that is easy to exchange continues to bring out on the market.
Touch-screen is boundless in the range of application of China, is mainly the inquiry of public information: as the service inquiry of the departments such as telecommunication bureau, the tax bureau, bank, electric power; The information inquiry in street corner, city; The data check of museum, the Art Museum; The flight at station, airport, train query; In addition be 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.Along with city infiltration in national life to information-based future development and computer network, information inquiry is all with touch-screen---and the tangibly form of displaying contents occurs.The ultimate principle of touch-screen is to touch with finger or other object the touch-screen that is arranged on display front end, the position (with coordinate form) touching is detected by the controller of touch-screen, and deliver to CPU by interface (as RS-232 serial port), thereby determine the information of input.
Touch-screen system generally comprises two parts: the controller of touch-screen and touch detecting apparatus.The Main Function of the controller of touch-screen is to receive touch information from touch detecting apparatus, and converts it to contact coordinate, then gives CPU, and its can receive the order that CPU sends simultaneously and be carried out.Touch detecting apparatus is generally arranged on the front end of display, and Main Function is the touch location that detects user, and sends touch screen controller to, and touch detecting apparatus is generally provided with meticulous conductive pattern.
Conductive pattern above touch detecting apparatus directly has influence on touch precision, and for traditional touch-screen, with finger touch, the diameter H in finger touch region generally has 8-9 millimeter, as shown in Figure 1.
So for traditional touch-screen, the electrode gap of conductive pattern is 4.5 millimeters of touch locations that finger just can be detected, along with the development and application of touch technology is constantly promoted, user improves constantly the requirement of touch-control precision, and start to replace finger to carry out touch-control (because the written diameter of pointer is less than the diameter of finger, can realize the more accurate touch-control of pen finger) to capacitive touch screen by pointer.Whether pointer can transmit and can be divided into active pointer and passive type pointer according to it.
For active pointer: be provided with circuit in pen, in the time of nib contact touch-screen, active pointer can be launched signal to touch-screen, touch-screen is by the signal accepting active pointer and launch and then judge that position of touch realizes touch control operation.As can be seen here, active pointer also needs the receiving system that on touch-screen, configuration transmits and matches with nib in the process using.
For passive type pointer: nib is conductor, connecting written penholder can be conductive material, can be also non-conducting material, and any circuit is not set in passive type pointer, point little nib by radius ratio and replace finger to touch touch-screen, to realize operation more accurately.With regard to cost, the cost of passive type pointer will be far smaller than the cost of active pointer.Therefore the application that, passive type pointer operates touch-screen is universal at a high speed.
The use of passive type pointer, usually make traditional touch-screen conductive pattern precision to mate, as shown in Figure 2, use pointer touch-control A, B, C, tetra-positions of D respectively, desirable result is to obtain A, B, C, tetra-coordinates of D, but A, two positions of B can only allow same induction electrode produce touching signals as can be seen from Figure 2, C, two positions of D also can only allow same induction electrode produce signal, hence one can see that above-mentioned A, B, C, tetra-positions of D are used that pointer is touch can only obtain 2 coordinates, and touch-control precision is undesirable.
