Description
Technical field
The utility model relates to a kind of soft keyboard, particularly a kind of software dish device that improves the input accuracy.
Background technology
Soft keyboard is a touch area of touch-screen normally, and touch-screen generally is divided into four kinds, is respectively:
1, resistive touch screen: this touch-screen utilizes pressure sensitive to control.The major part of electric resistance touch screen is a resistance film screen that cooperates very much with display surface, this is a kind of laminated film of multilayer, it with one deck glass or duroplasts flat board as basic unit, the surface scribbles layer of transparent oxidized metal (transparent conductive resistance) conductive layer, is stamped one deck outside surface cure process, smooth anti-friction plastic layer, its inside surface above again and also scribbles one deck coating, has the transparent isolating points of many tiny (less than 1/1000 inches) that two conductive layers is separated insulation between them.When the finger touch screen, two conductive layers has just had contact in the position, touch point, and resistance changes, and produces signal on X and Y both direction, send touch screen controller then.Controller detects this contact and calculates that (mode according to analog mouse operates again for X, position Y).
2, capacitive touch screen: four limits of capacitive touch screen have all plated long and narrow electrode, low-voltage AC field of its inner formation.Post the thin layer of layer of transparent on the touch-screen, it is a kind of special metallic conduction material.When the user touched capacitance plate, user's finger and workplace formed a coupling capacitance, because be connected to high-frequency signal on the workplace, so finger can siphon away a very little electric current, this electric current flows out the electrode from four angles of screen respectively; And the electric current of four electrodes of flowing through in theory is proportional with the distance of pointing four jiaos, and controller calculates by the precision to four current ratios, can draw contacting points position.
Two glass of capacitance touch screen not only can be protected conductor and inductor, can prevent effectively that more the external environment factor from impacting touch-screen, even if screen speckles with filth, dust or oil stain, capacitive touch screen still can accurately be calculated touch location.
3, infrared-type touch-screen: four limits of infrared touch panel arranged infrared transmitting tube and infrared receiving tube, their corresponding one by one infrared ray matrixes that intersects anyhow that forms.The user is when touch screen, and finger can block two infrared rays anyhow through this position, and controller can be judged touch point position by calculating.
Infrared touch panel is not subjected to electric current, voltage and electrostatic interference too, is suitable for some rugged environment.Its major advantage is cheap, easy for installation, can be used on the computing machine of each class.
4, surface acoustic wave type touch-screen: surface acoustic wave is hyperacoustic a kind of, and it is the mechanical energy ripple of propagating at the surperficial shallow-layer of medium (for example rigid material such as glass or metal).By wedge shape tribrach (according to the strict design of the wavelength of surface wave), can accomplish orientation, the emission of low-angle surface acoustic wave energy.
The display screen of this touch-screen is respectively equipped with ultrasound transmitting transducer and receiving transducer for four jiaos, can send a kind of ultrasound wave and cover screen surface.When finger touches display screen, owing to absorbed the acoustic wave segment energy, the reception waveform is changed, promptly waveform of a certain moment has a decay breach, and controller can calculate the position, touch point according to the signal of decay.
Surface acoustic wave touch screen is not subjected to such environmental effects such as temperature, humidity, and resolution is high, and fabulous scratch resistant property is arranged, and in the life-span long (5,000 ten thousand non-fault), transmittance height (92%) can keep clear bright image; Not drift is once proofreaied and correct when only needing to install; The 3rd (being pressure axis) response is arranged, and the most suitable public place uses.
But under the soft keyboard pattern,, when the user imports, be easy to cause pushing the wrong button because the restriction of touch-screen size can cause the size of button smaller.
