Show the large scale touch-screen of device it is possible to exclude the error touch control problem that palm leads to well.Acoustic pulse recognition touch-screen
Composition include glass or other hard materials, with assembling overleaf four signal receivers.Signal receiver is embedded in
On the diagonal reverse side corner of visibility region, and with by cable connection to control card.When the screen is touched produce collision or
User's finger or pointer pull generation sound wave when dragging on glass, sound wave be mapped to signal receiver from contact point four so as to
Produce proportional electronic signal.These signals are exaggerated in control card, are then translated to a digital information.These numerals
Information with leave database before in compare the position to judge touching.APR touch technology prevents surrounding and environment from making an uproar
The design of sound, principle is because these and is not matched that with the information deposited before.
Above two touch screen of the prior art has some defects in actual applications, such as surface acoustic wave touch screen,
In order to the precision of touch-control and accuracy need to arrange multiple soic wave transmitting energy converters, acoustic receiver transducer, and set in screen surrounding
Put reflector, lead to cost of manufacture higher；Surface acoustic wave touch screen intelligently senses soft object such as, finger, touch glove
Touch-control；Turning of screen surface is mad, and such as cut and dirt etc. all can affect the response of its touch-control；In addition, in surface acoustic wave touch
In, multi-point touch can produce the problem of delay, such as 10000fps（Frames Per Second, transmission frame number per second）Sensing
Device needs the response time of 6 ~ 8ms.
Content of the invention
In view of this it is necessary to provide that a kind of structure is relatively simple and the touch control display apparatus of better performances.
A kind of sensing method of touch control of offer is provided.
