Description
Technical field
The present invention relates to a kind of touch-control Display Technique, particularly relate to a kind of display control method based on finger hovering detection.
Background technology
In recent years, continuous advancement along with image display technology, it is made directly the advantage of instruction input owing to touch-control display panel has the mode that can pass through touching, just like becomes on market one of conventional display, and to be widely used in various electronic product.
In general, contact panel is broadly divided into capacitance type touch-control panel, electric resistance touch-control panel, optical touch panel etc. by type. For capacitance type touch-control panel, this touch technology is operated mainly by by the electric current induction technology of pressure. Such as, when finger touches metal level, human body electric field, user and touch screen surface form a coupling electric capacity, for high frequency electric, owing to electric capacity is direct conductor, then finger siphons away an only small electric current from contact point, and this electric current flows out from the electrode touch screen corner. The distance of the electric current and finger to corner that flow through four electrodes is directly proportional, and controller by the accurate calculating to these four current ratios, can finally draw touch point more specific location information on screen.
In the prior art, mutual inductance type capacitive touch component mainly utilizes the capacitance variations between scanning line (scanline) and data wire (dataline) to discriminate whether finger touch screen. When finger is not touched, the voltage variety on scanning line is a numerical value; When finger contact surface plate, owing to the electric capacity between scanning line and data wire changes, the voltage variety on scanning line is another numerical value, utilizes the difference between the two voltage variety on scanning line just to can determine whether that whether contact panel is touched. Additionally, experiment test shows, when finger presses and meets touch sensing (touchsensor), the Capacitance Coupled a certain numerical value of decline of generation, thus allowing testing circuit can confirm press points position according to concrete decline numerical value. But, when finger is not in time but directly encountering touch sensing, Capacitance Coupled now generally also can decline, but fall is little compared to the situation that above-mentioned pressing is touched, this finger near but the operation do not touched often hovers (fingerhover) also referred to as finger.
On the other hand, existing hand-held contactor control device generally uses gravity sensor (G-sensor) to sense screen shift is straight, horizontal type, flip horizontal or left and right upset. But this still can bring inconvenience, such as, although available gravity sensor is converted to straight or horizontal type during mobile phone photograph, but when photographer's one hand holds mobile phone, shutter key is also not always nearer apart from finger, thus causing operational inconvenience, even also mobile phone landing can be made because finger unclamps. And for example, when user right hand one hand arrests mobile phone, option list is generally presented on the left side of mobile phone screen, if now needing the inventory list on the left of taps screen, then the right hand is difficult to click because of distant. Further, user is when receiving calls, left ear or auris dextra are answered often; if now user is just having on earphone and is listening music; cell phone incoming call when receiving calls, it will usually the other side's spoken sounds is sent to the earphone of both sides, it is impossible to realize monaural sound transmission when one hand is answered.

Detailed description of the invention
In order to make techniques disclosed in this application content more detailed and complete, can refer to the following various specific embodiments of accompanying drawing and the present invention, labelling identical in accompanying drawing represents same or analogous assembly. But, it will be understood by those within the art that, embodiment provided hereinafter is not used for limiting the scope that the present invention contains. Additionally, accompanying drawing is used only for schematically being illustrated, and draw not according to its life size.
With reference to the accompanying drawings, the detailed description of the invention of various aspects of the present invention is described in further detail.
The finger of Figure 1A person of being shown with does not touch coupling electric capacity schematic diagram during (withouttouch) capacitance type touch-control panel, coupling capacitance variations schematic diagram during (fingertouch) capacitance type touch-control panel is touched and pressed to the finger of Figure 1B person of being shown with, the coupling capacitance variations schematic diagram when finger of Fig. 1 C person of being shown with hovering (fingerhover) and not yet touch capacitor type contact panel.
With reference to Figure 1A, Figure 1B and Fig. 1 C, in the prior art, mutual inductance type capacitance touching control panel mainly utilizes the quantity of electric charge change coupling electric capacity C between scan electrode 100 with data electrode 102 to discriminate whether finger touch screen. In figure ia, finger is not touched, and the quantity of electric charge does not change, and corresponding waveform is such as shown in W1. In fig. ib, when finger 104 is touched and presses panel, owing to the quantity of electric charge coupling electric capacity C between scan electrode 100 with data electrode 102 there occurs large change, the Capacitance Coupled drop-out value produced is Δ V1, corresponding waveform waveform W1 such as shown in W2, when dotted portion therein is do not touch; In fig. 1 c, when finger 104 is near but not directly touching (and the distance between panel is d), also a little change can be there is in the quantity of electric charge coupling electric capacity C between scan electrode 100 with data electrode 102, Capacitance Coupled drop-out value now is Δ V2, and corresponding waveform is such as shown in W3. From the contrast of Figure 1B and Fig. 1 C it can be seen that finger hovers, fall time (fingerhover) is little compared to the fall that pressing is touched time (fingertouch).
Fig. 2 (a) to Fig. 2 (d) be shown respectively existing capacitance type touch-control panel utilize gravity sensor (G-sensor) carry out straight, horizontal type, flip horizontal and left and right upset time view.
As described in the background section, existing hand-held contactor control device generally use gravity sensor (G-sensor) sense Touch Screen 20 turn to into straight (corresponding diagram 2 (a)), horizontal type (corresponding diagram 2 (b)), flip horizontal (corresponding diagram 2 (c)) or left and right overturn (corresponding diagram 2 (d)). But, the sensing of gravity sensor still can bring inconvenience, for instance, when photographer's one hand holds mobile phone, shutter key not always distance finger are relatively near, thus causing operational inconvenience, even also can make mobile phone landing because finger unclamps. And for example, when user right hand one hand arrests mobile phone, option list is generally presented on the left side of mobile phone screen, if now needing the inventory list on the left of taps screen, then the right hand is difficult to click because of distant.
In order to overcome drawbacks described above of the prior art or deficiency, the invention provides a kind of display control method based on finger hovering detection. Wherein, Fig. 3 is shown according to one embodiment of the present invention, based on the FB(flow block) of the display control method of finger hovering detection.
With reference to Fig. 3, in the method, step S101 being first carried out, read a sampled data (such as, the digital signal after analogue signal conversion), this sampled data is corresponding to the change in electrical charge amount of Inductance and Capacitance; Then step S103 is performed, judging whether finger hovering operation according to sampled data, if existing, entering step S105, record the hovering value (hovervalue) corresponding with finger hovering operation, if being absent from, entering step S107, detecting whether there is pressing operation. If there is pressing operation, performing step S109 and S111 successively, running the touch control procedure corresponding with pressing operation, and report touch point (touchpoint) to operating system.If there is no pressing operation, then perform step S113, judge whether to yet suffer from hovering value, if existing, then perform step S115 and S117, by touching controller (touchcontroller), hovering value is reported operating system, operating system determine the need for the synchronization control display pattern when running touch control procedure.
Such as, when photographer's one hand holds mobile phone, the available hovering value (hovervalue) of control method adopting the present invention learns the position that one hand is taken, and by side nearer for shutter key intelligent mobile to distance finger, shutter key moves to finger tip simultaneously and facilitates user one-handed performance. And for example, when user right hand one hand arrests mobile phone, adopt the control method of the present invention to may utilize hovering value and option list intelligence is moved to hand-held side, make user be easy near point and select this inventory list. Further, user is when receiving calls, even if user is just having on earphone and is listening music, cell phone incoming call when receiving calls, adopt the available hovering value of control method of the present invention that the other side's spoken sounds is adjusted to L channel transmission or R channel transmission completely.
At a specific embodiment, when the change in electrical charge amount of Inductance and Capacitance is between a first threshold and a Second Threshold, it is judged that there is finger hovering operation; When the change in electrical charge amount of Inductance and Capacitance is more than Second Threshold, it is judged that there is pressing operation, wherein first threshold is less than Second Threshold. This is because, the fall (corresponding to change in electrical charge amount) when the fall (corresponding to change in electrical charge amount) during finger hovering is compared to pressing touching is little.
When Fig. 4 illustrates the display control method adopting Fig. 3, confirmed the principle schematic of the mode of holding of user by finger hovering operation. Fig. 5 (a)～5 (h) is shown respectively the schematic diagram of the finger hovering operation of Fig. 4 hovering value coding under different modes of holding.
With reference to Fig. 4, capacitance type touch-control panel 32 includes four edges, respectively top margin (topside) 32T, base (bottomside) 32B, the left side (leftside) 32L and the right (rightside) 32R. When finger 30 hovers above panel and spacing is d, touching controller holds mode according to finger projection of shape (as indicated with broken lines in fig. 4) the confirmation user sensed. In the diagram, finger projection of shape is a lower-left shape to upper right. It is preferred that the present invention can preset each edge (32T, 32B, 32L and 32R) of contact panel 32 and the combination holding between the mode mark of user, then assign the hovering value of correspondence according to combination mark. Such as, hovering value is binary coding.
In conjunction with Fig. 5 (a) to Fig. 5 (h), the difference of the different corresponding capacitance type touch-control panels of hovering value coding holds mode. In Fig. 5 (a), left hand holds the left side by panel, and hovering value is 000; In Fig. 5 (b), the right hand holds the right edge by panel, and hovering value is 001; In Fig. 5 (c), the right hand holds the top margin by panel, and hovering value is 100; In Fig. 5 (d), left hand holds the base by panel, and hovering value is 101; In Fig. 5 (e), left hand holds the right edge by panel, and hovering value is 010; In Fig. 5 (f), the right hand holds the left side by panel, and hovering value is 011; In Fig. 5 (g), the right hand holds the base by panel, and hovering value is 110; In Fig. 5 (h), left hand holds the top margin by panel, and hovering value is 111. Thus, hold mode (left hand and the right hand) by two kinds of the four edges of panel and each edge and can produce 8 kinds of combinations, every kind of combination correspond to unique hovering value, after hovering value is reported operating system by touching controller, operating system just can be determined whether to need the synchronization control display pattern when running touch control procedure.
Adopt the display control method based on finger hovering detection of the present invention, first read the sampled data corresponding with the change in electrical charge amount of Inductance and Capacitance, and judge whether finger hovering operation according to sampled data, if there is finger hovering operation, then record corresponding hovering value, next detect whether there is pressing operation, if there is pressing operation, then run the touch control procedure corresponding with pressing operation, then judge whether to yet suffer from hovering value, and by touching controller, hovering value is reported operating system, last operation system determines the need for the synchronization control display pattern when running touch control procedure according to hovering value. compared to prior art, the present invention utilizes finger hovering and Inductance and Capacitance variable quantity when not yet touching to screen to hold direction to what judge user, thus the position of appearing of display direction or the application menu that need to adjust picture can be decided whether according to the hovering value corresponding with holding direction. such as, when photographer's one hand holds mobile phone, the available hovering value (hovervalue) of control method adopting the present invention learns the position that one hand is taken, and by side nearer for shutter key intelligent mobile to distance finger, shutter key moves to finger tip simultaneously and facilitates user one-handed performance. and for example, when user right hand one hand arrests mobile phone, adopt the control method of the present invention to may utilize hovering value and option list intelligence is moved to hand-held side, make user be easy near point and select this inventory list. further, user is when receiving calls, even if user is just having on earphone and is listening music, cell phone incoming call when receiving calls, adopt the available hovering value of control method of the present invention that the other side's spoken sounds is adjusted to L channel transmission or R channel transmission completely.
Above, the specific embodiment of the present invention is described with reference to the accompanying drawings. But, those skilled in the art are it is understood that when without departing from the spirit and scope of the present invention, it is also possible to the specific embodiment of the present invention is done various change and replacement.
