Abstract
The invention provides a capacitive touch screen scanning method which comprises the following steps: connecting a touch screen with a host machine to detect touch signals, and presetting at least one hot region on the touch screen according to different operation modes of the host machine; selecting corresponding scanning modes according to the operation modes of the host machine to scan the corresponding hot regions, and determining the positions and the number of the true touch signals; and if the number is smaller than a first threshold or no touch signal is detected in the hot region, scanning the inductive electrodes in the regions other than the hot regions in a self-coupling mode, and scanning the inductive electrodes in the corresponding regions in a cross coupling mode, thereby determining the true touch positions. Related control can be realized during projection without additional hardware.
Description
Technical field
The present invention relates to a kind of touch screen scanning method, especially a kind of capacitive touch screen scan method.
Background technology
In recent years, along with the develop rapidly of touch technology, increasing product begins to utilize touch-control system to finish direct control to destination object, thereby has replaced traditional mouse, input equipments such as keyboard, thus saved the space, carry convenient.More common in the market panel computer, touch-control mobile phone etc. have all adopted touch control operation.
Touch-screen mainly is that the electrode by directions X and Y direction detects electric capacity, and according to changes in capacitance before and after touching, determines lateral coordinates and along slope coordinate respectively, is combined into the touch coordinate on plane then.Existing touch-screen product is when detecting user's touch point, and touch-screen needs to carry out full screen scanning often, though the accuracy of Bao Zhenging like this, the speed that scans has slowed down.Function based on the touch-screen product, the user uses the custom of product to have difference under different working modes, for example when the user uses the mobile phone browsing pictures, because the limitation of touch-screen size, the user often only can touch the zone of central authorities, perhaps omits the zone on inclined to one side both sides.And the touch-screen product is still determined user's touch point by full screen scanning, and the speed that so just slowed down relies in the battery powered touch-screen product (such as mobile phone) at some, also can influence the working time of touch-screen product greatly.
Therefore need badly a kind of energy-conservationly, can accurately detect user touch point, and dwindle the touch-screen product of scanning area.
Summary of the invention
At the deficiencies in the prior art, the technical matters that the present invention solves provides and a kind ofly can be used for when projection the system that can utilize shade or high light to control.
For solving the problems of the technologies described above, technical scheme of the present invention is achieved in that a kind of capacitive touch screen scan method, described touch-screen links to each other with main frame, be used for the senses touch signal, according to the different mode of operation of described main frame, default at least one hot spot areas on described touch-screen, described method also comprises: according to the mode of operation of described main frame, select corresponding scan mode to scan corresponding hot spot areas, determine the position and the number of actual touch signal; If described number less than first threshold or in described hot spot areas if do not detect touch signal, then the induction electrode in the zone outside the described hot spot areas being carried out the self coupling mode scans, and the induction electrode of respective regions is carried out the mutual coupling mode scan, to determine real touch location.
Beneficial effect of the present invention is as follows: energy-conservation, and scan mode combined with the duty of main frame, use habit that can adaptive user accurately detects user touch point, and dwindles scanning area.
Description of drawings
Fig. 1 is the system architecture diagram of the embodiment of the invention;
Fig. 2 is the hot spot areas synoptic diagram of the embodiment of the invention;
Fig. 3 is the workflow diagram of the embodiment of the invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples:
See also Fig. 1, touch-control system 100 comprises touch interface 101, main frame 102.Wherein, touch interface 101 is used to detect user's touch point, and relevant information is sent to main frame 102.Function corresponding is triggered in 102 touch points according to the user of main frame, and adds up the touch point of user under different mode respectively.When touch-control system 100 being carried out refer to operation more, touch-control system 100 need carry out the scanning of mutual coupling mode (hereinafter to be referred as the mutual capacitance mode) or self coupling mode (hereinafter to be referred as the self-capacitance mode) to the induction electrode in relevant zone, so that determine user's true touch point.
According to the pattern of main frame 102 work, be default at least one hot spot areas of every pattern, determine on touch face 101 that promptly at least one zone is a hot spot areas, and it is carried out priority scan.
Being in full frame browsing pictures with touch-control system 100 is that example illustrates workflow of the present invention.When full frame browsing pictures, the instruction that the user uses always comprises convergent-divergent, switches, withdraws from or the like.And those instructions often can trigger by the touch of some, so the pattern of full frame browsing pictures is set up first threshold, promptly effectively touch and count.The A part of the middle section of touch interface 101 is divided into hot spot areas.So touch-control system 100 is with priority scan A part.Be set in advance under the mode of operation of full frame browsing pictures, the scan mode of hot spot areas A is the mutual capacitance mode.
Please consult Fig. 2 and Fig. 3 simultaneously.At first, judge the mode of operation (S301) of main frame 102, select corresponding scan mode then, scan corresponding hot spot areas (S302); Then, judge whether to detect touch signal? (S303) if detect touch signal, then add up the position and the number (S304) of touch signal, if do not detect touch signal, then the self coupling mode being carried out in the zone outside the hot spot areas scans, determine relevant range (S306), then mutual capacitance scanning is carried out in the relevant range, to determine actual position (S307); If less than first threshold, same at the number of the detected touch signal of hot spot areas, the zone outside the hot spot areas is scanned, promptly forward step (S306) to.If the number of the detected touch signal of hot spot areas then directly is defined as the actual touch signal with this touch signal more than or equal to first threshold.
Behind definite actual touch signal, touch-control system 100 will be classification with the mode of operation, the position and the number of statistics touch signal, and after a default stage, adjust the attributes such as position, size, shape of corresponding hot spot areas.The default stage can be a period of time or certain touch number of times.Thereby, can adjust the position and the size of hot spot areas according to user's custom, significantly reduced the time of location.And along with the increasing of user service time, touch-control system 100 will more and more adapt to user's use habit, be rich in hommization.
Its corresponding scan mode of mode of operation in the said process only is to be used for for example, is not to be used for limiting the scope of the invention.The position of above-mentioned first threshold and hot spot areas and size are by User Defined.
The above only is a preferable possible embodiments of the present invention, and is non-so promptly limit to claim of the present invention, so the equivalent structure that uses instructions of the present invention and diagramatic content to do such as changes, all in like manner is included in the scope of the present invention.
