The following principle that the Touchless manipulation sensing of capacitive technologies is described in detail in detail earlier.Electric capacity is meant the ability of accommodate electric field.Common plane-parallel capacitor, its electric capacity are C=ε S/d; Wherein, ε is the specific inductive capacity of medium between pole plate, and S is the pole plate area, and d is the distance between pole plate; As can be seen, when the distance between the pole plate reduced, capacitance can increase from the expression formula of electric capacity.Fig. 3 illustrates the elementary cell of touch-screen, and as shown in Figure 3, the elementary cell of touch-screen comprises non-contacting emitter (Transmitter) and receiving pole (Rx).During duty, the capacitor charging that touch screen controller forms for earlier emitter and receiving pole, as shown in Figure 3, black line is represented the electric field of two interpolars.As the finger near the time, as shown in Figure 4, form capacitor between finger and emitter and the receiving pole respectively, thus the generation electric field; Wherein, because the plate area of emitter is bigger, so the electric field between finger and the emitter is greater than the electric field between finger and the receiving pole.
Finger near having weakened electric field between emitter and the receiving pole, that is: reduced magnitude of voltage, touch screen controller can detect the touch unit that magnitude of voltage has reduced, and then judges the position of finger touch thus; Along with distance asymptotic between finger and the touch-screen, the electric field that weakens these touch unit two interpolars is just remarkable more, that is: the magnitude of voltage of touch unit two interpolars is just more little.Therefore, the distance threshold that sets in advance need be converted to the voltage threshold that equipment can be discerned, that is: set the voltage threshold of touch unit two interpolars of triggerings " approaching " incident instruction correspondence, by voltage threshold judge the finger and touch-screen between distance, when the magnitude of voltage of judging two interpolars when touch screen controller reaches preset threshold, " approaching " instruction is reported CPU.
When practical application, according to the electric capacity computing formula as can be known, the pairing finger of the voltage threshold of setting can the variation to some extent owing to the different fingers of different user with the distance between the touch-screen.
When finger continue near and when finally touching touch-screen, as shown in Figure 5, finger to the electric field of two interpolars weaken more, at this moment, when the magnitude of voltage that touch screen controller is judged two interpolars reaches the voltage threshold of predetermined contact, the instruction of " contact " incident is reported CPU.
The present invention does not get rid of other contactless touching techniques, and as infrared technology, in these contactless touching techniques were used, the user can use suitable object or accessory to operate touch-screen, and was not limited to finger.

After step 603:CPU receives instruction, corresponding character of coordinate figure or the icon finding out and report according to predetermined corresponding relation, and corresponding character or icon highlighted processing;
Here, described corresponding relation can be the on all four coordinate corresponding relation of touch-screen and display, also can be other corresponding relation, that is: can be can be according to other any corresponding relation of corresponding character of the coordinate figure that corresponding relation finds and reports or icon;
Described corresponding character or icon are highlighted processing, it is big to be that respective symbols on the user interface or icon become, as shown in Figure 7, and at this moment, though the button that the user triggered is blocked by finger, the amplification of character D demonstration still can be crossed finger and be discerned by the user; Can also be that respective symbols on the user interface or icon obviously show in the zone at other, as shown in Figure 8, at this moment, on the dummy keyboard and the corresponding character D of coordinate that reports be presented at outside the keyboard, thereby hidden blocking of finger; It is big to be that respective symbols on the user interface or icon become, simultaneously, respective symbols on the user interface or adjacent other character or the icon of icon periphery diminish, as shown in Figure 9, at this moment, amplify demonstration with the corresponding character D of the coordinate that reports on the dummy keyboard, simultaneously, the character C and the E on the character D next door of choosing can dwindle demonstration accordingly, like this, user's display interface has not only been realized the character chosen or the clear demonstration of icon, and character of Fang Daing or icon also can not block the not visual of next door character or icon simultaneously.
Step 604: when finger further contact with touch-screen, and when reaching the voltage threshold of " contact " incident correspondence, touch screen controller instructs " contact " and reports CPU;
Here, described " contact " instruction comprises: the contact point coordinate figure;
If point further close with touch-screen, and do not reach the voltage threshold of " contact " incident correspondence pairing apart from the time, respective symbols on the user interface or icon keep highlighting state.
After step 605:CPU receives instruction, choose respective symbols or icon, trigger corresponding preset program operation according to the contact point coordinate figure;
Here, the described preset program operation that triggers correspondence is meant that character is presented at predetermined display area or the pairing program run of icon.
When practical application, a contactless soft-touch control can also be set, digital terminal equipment can be switched between physical button and virtual key, after opening switch, use contactless touching technique to import, behind the off switch, use physical button to import.
