Description
Technical field
The present invention relates to a kind of contact panel, particularly a flexible multi-touch control point panel.
Background technology
Now, electronic installation provides more and more functions and more and more small size and weight.By continuous integration more function, reduce cost, and increase reliability.Usually contact panel provides a touch control display that is easy to control in conjunction with general display such as cathode-ray tube display (CRTs), LCD (LCD), plasma display panel and electroluminescent display etc.The instrument of Chang Yong touch surface manufacturing can only be as the position of sensing one touch-control now.
Today, many computer input units.Its operating type normally utilizes a moving cursor and/or directly elects on screen.For example, input media comprises button or key, mouse, trace ball, touch pad, distant bar, contact panel etc.And contact panel more and more receives an acclaim, and reason is that he operates easily and elasticity is big and price constantly descends.Contact panel allows the user to use finger or stylus directly or indirectly to utilize cursor to make one's options on contact panel.Generally speaking, contact panel can be confirmed touch-control and position, supplies computer system processor touch-control data then, and is providing a corresponding action according to the touch-control data thereafter.

On the glass plate of fluctuation formula Touch Screen then without any filming.Be positioned at the converter of four jiaos of screens, can convert the signal that comes self-controller on the glass plate ultrasound wave, the reverberator that is positioned at four limits then is responsible for producing standing wave pattern.In case the finger contact screen will sponge standing wave partly.This moment, converter can detect relative decay, and controller just can be made the coordinate of finger.
The strainometer technology is to be to decide when screen at four corners dress foil gauges to be touched and the deflection that produces at screen.This technology can also be measured the Z axle.
Dispersive signal technology (DST) when we touch contact panel, can form certain seismic wave in the panel the inside from development in 2002 so far, then this complicated seismic wave is converted, and calculate physical location, with general surface wave different be that DST is the technology of a kind of detecting at medium the inside ripple, so, any surperficial water droplet, dirty, or grease can not have influence on the detecting of touching, cause any interference, DST does not have the restriction of size.
Acoustic impulse wave identification touch technology (APR) is measured the position of the point that is touched on glass in a kind of simple and elegant voice recognition mode.Its key is all to produce unique sound when the contact of each position on glass.Four small transceivers that are attached to the touch-screen edge glass receive the sound of contact, and this sound is compared with the tabulation of prior each position sound on glass of noting then by the controller digitizing, and cursor position is updated to touch location immediately.The design of APR can be ignored external and noise all around, because they are misfitted with the sound recordings of record in advance.
Above technology wherein as electric capacity, can be done the detecting of multi-touch.And multi-touch control point panel is the new trend of contact panel.But what be used for these multi-touch control point panel devices is solid, and its rigid substrates or material can weaken the mobility of these devices, as is used in mobile computer, palmtop computer, mobile phone etc.The weight of contact panel and shock-resistant ability are to make running gear consider whether to use the key factor of contact panel.Mobile device also more requires its retractility than general stationary installation.Hard, frangible, weight does not greatly all meet the required assembly of light now, resilient device.Similarly consideration also is applicable to the requirement that is installed in giant display on automobile and the wall.Hard, frangible substrate or material have also increased the thickness of product, reduce a product in the coml advantage.
Touch-control sensing also need be on glass substrate sensor installation.These sensors then further increase weight, cost and the complexity of instrument.The plane contact panel does not meet the demand of on-plane surface display or curved surface display yet.In addition, make crooked hard substrate and need expensive processing.Aspect glass, also must meet demand from glass substrate cutting equally, these all make makes the expensive and time-consuming of ten minutes.All these weakness all can be improved at flexible multi-touch control point panel.
