Embodiment
In tradition, only adopt in the self-capacitance screen of self-capacitance (self-capacitance), its glass surface with a kind of transparent conductive material as ITO is made into horizontal X and the longitudinal electrod-array of Y, these horizontal and vertical electrodes form electric capacity with ground respectively, that is to say that self-capacitance is electrode electric capacity over the ground.When finger touch shields to self-capacitance, the electric capacity of finger will be added in screen body capacitance, and making to shield body capacitance amount increases.When touching detection, self-capacitance screen detects respectively horizontal and vertical electrod-array successively, according to the variation of electric capacity before and after touching, determines respectively lateral coordinates and along slope coordinate, is then combined into the touch coordinate of plane.The scan mode of self-capacitance, is equivalent to the touch point on touch-screen to project to respectively X-axis and Y direction, then in X-axis and Y direction, calculates coordinate respectively, is finally combined into the coordinate of touch point.This principle of work of self-capacitance makes self-capacitance cannot realize multi-point touch operation, yet because self-capacitance can produce more intense signal, so self-capacitance can detect the suspension operation apart from the highest 20mm place, screen top.
In tradition, only adopt in the mutual capacitance screen of mutual capacitance (mutual capacitance), it is also with ITO, to make transverse electrode and longitudinal electrode at glass surface, the place that two arrays of electrodes intersects will form electric capacity, is also the two poles of the earth that this two arrays of electrodes has formed respectively electric capacity.When finger touch shields to mutual capacitance, affected the coupling between near two electrodes in touch point, thereby changed the electric capacity between these two electrodes.While detecting mutual capacitance size, horizontal electrode sends pumping signal successively, all electrodes receive signal simultaneously longitudinally, can obtain like this capacitance size of all horizontal and vertical electrode joints, i.e. the capacitance size of the two dimensional surface of whole mutual capacitance touchscreens; According to touch screen two-dimensional capacitance change data, can calculate the coordinate of each touch point, thereby even have a plurality of touch points on screen, also can calculate the true coordinate of each touch point.This principle of work of mutual capacitance can realize multi-point touch, yet because the some area of each X-axis and Y-axis intersection is very little, the electric field that causes sensor to produce is also very little, it is very difficult sensed that finger is suspended in screen top, so realize only according to mutual capacitance the operation that suspends, is very difficult.
For realizing suspend operation and multi-point touch operation, a kind of suspension touch-control scheme is suggested.Suspension touch-control is a kind of mutual capacitance and these two kinds of technology that capacitance type sensor is worked simultaneously of self-capacitance applied.That is to say, this Technology Need adds two kinds of capacitance type sensors, i.e. mutual capacitance and self-capacitance simultaneously on touch-screen.Mutual capacitance is for realizing normal traditional multi-point touch; And self-capacitance can produce than the more powerful signal of mutual capacitance to detect farther finger induction, it detects distance range can reach 20mm.Therefore,, having applied above the terminal screen of this technology, can produce the electrode network that a terminal can detect.When user's touch scope enters in this range of signal, terminal can judge user's touch operation by internal processes, thereby produce result corresponding to user's touch operation.So in conjunction with self-capacitance and mutual capacitance, just can realize suspension touch-control.
The application, just based on suspension touch technology, has proposed a kind of disposal route of touch control operation, to realize the high-level efficiency of terminal device, convenient input.For ease of explanation, first some terms or the concept in each embodiment of the application, used are made an explanation.
(1) hover mode: when this pattern, touch control object can get final product control terminal screen and makes it make corresponding response as finger etc. in the situation that not contacting terminal screen.
(2) normal mode: when this pattern, touch control object could make it make corresponding response by control terminal screen as the needs such as finger contact or touch terminal screen, conventionally can support multi-point touch under this pattern.
(3) suspend and operate: refer to that touch control object, as finger waits with touch screen in the situation of non-zero distance (not contacting), makes terminal screen make the operation of corresponding response.
(4) touch operation: refer to that touch control object need to, in the situation that contacting and touch terminal screen, make terminal screen make the operation of corresponding response as finger waits.
Below by embodiment, by reference to the accompanying drawings the application is described in further detail.
Embodiment 1
The application provides a kind of terminal device, comprises capacitive touch screen, and this touch-screen adopts two kinds of capacitance type sensors, i.e. mutual capacitance and self-capacitance simultaneously.This terminal device can be such as mobile phone, personal digital assistant or other hand-held calculating or game device, digital camera, kneetop computer etc.From function, divide, terminal device also can comprise receiver module 101 as shown in Figure 1, normal touch-control module 102 and suspension touch-control module 103.
When normal touch-control module 102 enters the instruction of normal control mode touch mode for receive sign in command reception module, detect touch control object as the touch operation of finger on screen, determine the touch location of touch control object on screen, and make corresponding response.That is to say, normal touch-control module is corresponding to normal mode, and now, what on the screen of terminal device, work is mutual capacitance, for completing normal touch screen induction, comprises multiple point touching.In other embodiment, also can utilize self-capacitance to respond to, what certainly now realize is single-point touches.No matter be to adopt self-capacitance or mutual capacitance to respond to, the induction that it relates to and the response that this is made, all can realize with reference to existing correlation technique, do not describe in detail herein.
When suspension touch-control module 103 enters the instruction of suspension control mode touch mode for receive sign in command reception module, detect touch control object in the position apart from screen non-zero distance, the position of determining described non-zero distance is mapped in the correspondence position on screen, judge whether described correspondence position falls into suspension region, the action of the touch control object that if so, response senses.Usually, in suspension touch-control module 103, utilize self-capacitance to respond to, the response how to make being specifically related to, can realize with reference to existing correlation technique, does not describe in detail herein.
In each embodiment of the application, suspension region is a fixed area of screen, and the border in suspension region does not contact with the border of described screen, the size that the size in region of suspending is less than screen for example, as shown in Figure 2, screen is rectangular area B, and suspension region is rectangular area A and is positioned at region B.The distance on each border of each frontier distance screen in suspension region can be according to the optimum distance of debugging effect selection, and the induction of the screen sides that may exist for example, during according to the screen of hand held terminal equipment is debugged and determined.In a kind of embodiment, the position in suspension region is just pre-set before terminal device dispatches from the factory.The setting in suspension region be because user operation time because hand can held terminal device as mobile phone, cause the both sides of the transverse axis of mobile phone to have induction amount, this induction amount can be similar with the induction amount size suspending, therefore, the processor of terminal device is (during the touch-control module that suspends work) when calculating suspension, the induction amount of screen the right and left can be removed not very, or only the induction amount within suspension region sensing is amplified, make the signal within suspension region that senses more clean, thereby while detecting a small amount of capacitance variations in suspension region, just can capture the action of touch control object when the position corresponding to suspension region, thereby reach, can still can detect touch control object as the action of hand in the height left and right of 15-20mm.The magnitude range in this suspension region selects best effect to determine when in debugging effect.
In embodiment, suspension region is for identifying the action of suspension, the action of making when to be touch control object do not touch on screen as finger, normal touch function is realized in the whole region of screen when normal mode, when hover mode, normal touch function is realized in the extra-regional region that suspends of removing of screen, the action horizontally slipping when unsettled and the action sliding up and down need to be identified in the region that suspends, do not do the identification of click action, and the whole region (at normal mode) of screen needs finger touch just to respond to screen.Under hover mode, finger unsettled slip in removing of screen suspends extra-regional region can not be identified, only in the scope in suspension region, can identify, under normal mode, the processing of finger when the normal contact screen in suspension region and the processing of whole screen are the same, are all the processing of normal touch.
Adopt the disposal route of the touch control operation of embodiment, application program in terminal device is picture library for example, when the application that enters into browsing pictures, selection enters hover mode, and now, user can use suspended pattern page turning preview picture,, user slides on screen without touching on screen, and only need be under upper left right or up, suspension region unsettled slide, the track of slide can be straight line or curve.This terminal device of mentioning in asking refers to the computer equipment that can use in movement, comprises the widely used all mobile hand-held devices of present people, comprises smart mobile phone, MID, panel computer, vehicle-mounted computer etc.
The present embodiment is introduced suspension touch technology when inputting by user, for providing variation, user's input operation selects, make can input by normal touch operation in normal touch situation, when adopting suspension touch-control, controlling in suspension region adopted to the operation that suspends, the extra-regional screen area that suspends is adopted to normal touch operation.
Embodiment 2
