The application first embodiment is related to a kind of touch controller, is applied to touch device, for example, in being integrated with, the touch device of large scale touch screen.
Please refer to the structure and its application schematic diagram of touch controller shown in FIG. 1.Touch controller 101 includes: that processing unit 1011 and driving sensing unit 1012, processing unit 1011 are connected with driving sensing unit 1012.The structural schematic diagram of the touch panel 102 of touch device shown in Fig. 2 is please referred to, driving sensing unit 1012 is used to connect touch area 1021 and the frame region 1022 of the touch panel 102 in touch device 10.Wherein, it is formed on touch area 1021 touch control detection unit 1023 (being not shown in Fig. 2), touch control detection unit 1023 is used to detect the touch-control input information on touch area 1021.Frame region 1022 is equipped with frame detection unit 1024 (being not shown in Fig. 2), for detecting the frame touch information in frame region 1022.
Sensing unit 1012 is driven to be used to provide pumping signal to touch control detection unit 1023 and frame detection unit 1024, and receive the inductive signal of touch area 1021 and frame region 1022, drive sensing unit 1012 that the inductive signal received is sent to processing unit 1011, processing unit 1011 is for receiving the inductive signal from touch area 1021 and frame region 1022, or can be also used for shield detection to the edge maloperation for meeting preset condition, i.e. processing unit 1011 is used for the touch coordinate according to the input acquisition of information touch operation of the touch-control of touch area 1021, and when judging touch operation while touching in frame region 1022, inhibit touch coordinate.Specifically, processing unit 1011 can input information according to the touch-control of acquisition and obtain the touch-control coordinate of touch area 1021, and judge whether this touch is edge maloperation according to touch-control input information and frame touch information, if it is determined that edge maloperation, then inhibit or shield this touch operation, obtained touch-control coordinate system is not reported into, so that screen will not respond this touch operation.
In one example, processing unit 1011 can be also used for inputting touch-control information and frame touch information reporting to primary processor 11, the edge maloperation arrived for 11 shield detection of primary processor, wherein, primary processor 11 belongs to touch control terminal, primary processor 11 and the communication mode of processing unit 1011 are well known to those skilled in the art, and details are not described herein again.It can not also include that the function of judgement or inhibition is handled by ppu for determining, inhibiting the processing unit of edge maloperation that is, the touch controller of this paper, both may include the processing unit for determining or inhibiting edge maloperation.
Specifically, driving sensing unit 1012 can be an entirety, sensing unit 1012 is driven to be used to provide pumping signal to touch control detection unit 1023 and frame detection unit 1024, and the inductive signal for receiving the feedback of touch control detection unit 1023, processing unit 1011 is used to obtain touch-control input information according to the inductive signal fed back from touch control detection unit 1023, driving sensing unit 1012 is used to receive the inductive signal of the feedback of frame detection unit 1024, processing unit 1011 is used to obtain frame touch information according to the inductive signal fed back from frame detection unit 1024.Touch-control inputs information for example, touch-control input information (such as touch information of palm) that touch-control input information, the touch-control input information of user's finger and other touch control detection units 1023 of stylus can detecte.
Processing unit 1011 is specifically used for whether there is the edge maloperation for meeting preset condition according to the frame touch infomation detection of touch-control input information and frame region 1022 on touch area 1021, and the edge maloperation that shield detection arrives.Edge maloperation is primarily referred to as that the desired touch operation of non-user at 1021 edge of touch area occurs.For example, the palm of user may rest on touch area 1021, and the touch operation non-user of palm it is expected when being inputted using stylus, it is likely to result in terminal and accidentally responds.When palm rests on the near center location of touch area 1021, since the shape and area of palm are significantly greater than finger, so by obtaining screen volume data (such as the shape and area touched on touch area 1021), and the touch shape and area that will acquire and preset shape and area, such as the shape and area of finger are compared, that is, may recognize that and shield volume data caused by touching due to palm；When the edge of palm to touch area 1021 is mobile and rests on the shape of 1021 edge of touch area and area and the close finger of user, then it is difficult to for palm data being at this time distinguished with finger data.
In the present embodiment, preset condition is, for example, while touching in touch area and frame region.Specifically, processing unit 1011 is after obtaining touch-control input information and frame touch information, it can judge whether frame region 1022 is touched according to frame touch information, if frame region 1022 is touched, then the quantity that information continues to test the touch operation on touch area 1021 can be inputted according to touch-control, if the quantity of the touch operation on touch area 1021 is consistent with the quantity for the position that frame region 1022 is touched, then mask whole touch operations on touch area 1021, such as a position in frame region 1022 is touched, and a touch operation is only detected on touch area 1021, then shield the touch operation.When the quantity of the touch operation on touch area 1021 is greater than the quantity of the touch location in frame region 1022, the touch location of the touch operation on touch area 1021 can be continued to test, and masks identical as the quantity of the touch location in frame region 1022 and touches the touch operation at 1021 marginal position of touch area.Therefore, present embodiment is not necessarily to calculate the touch shape and area of touch operation on touch area, according only to frame region 1022 whether touched and touch area 1021 on the touch location of touch operation can quickly detect edge maloperation.When that can not identify edge maloperation according to the touch location of the touch operation on the quantity of the touch location in frame region 1022 and touch area 1021, edge maloperation further can also be continued to test according to the touch area of the touch operation on touch area 1021.Such as, when the marginal position of touch area 1021 exists simultaneously multiple touch operations and whether frame region 1022 is only capable of providing it and is touched but cannot provide the quantity of touch location thereon, processing unit 1011 can also compare the size of the touch area of multiple touch operations of the marginal position of touch area 1021, such as the size of the touch area of two touch operations, and then the biggish touch operation of area will be touched as edge maloperation, to shield the edge maloperation.In, for large-sized touch control terminal, since user's finger is touched in touch area and the chance very little of frame region simultaneously, and palm touch simultaneously is relatively very big in the chance of touch area and frame region, so meeting the touch operation of above-mentioned preset condition by detection, edge maloperation more can be quickly and accurately detected.
As a kind of replacement, preset condition can also be while touch the touch area in touch area and frame region and on touch area greater than preset threshold.Preset threshold is, for example, the area of user's finger, in this way, it is detecting the touch operation on touch area 1021 while touching when in frame region 1022, continue to calculate touch area of this touch operation on touch area 1021, if the area that touches area be greater than user's finger of this touch operation on touch area 1021, shields this touch operation.Since finger is touched at touch area 1021 and frame region 1022 simultaneously, the touch area touched on touch area 1021 can become smaller, so can more precisely identify palm while touch the edge maloperation at touch area 1021 and frame region 1022.In practical applications, the difference of other operating main bodies and finger size can also be utilized, to identify its edge maloperation caused by 1021 edge of touch area, present embodiment is not particularly limited for touching main body.For area is greater than the palm of finger, touch-control input information (i.e. palm generated on touch area 1021 screen volume data) on combination of touch control region 1021 and the frame touch information in frame region 1022, such as whether frame is touched, it can is more precisely identified and is shielded volume data (i.e. edge maloperation) caused by being touched by palm.
In practical applications, it since the input that palm is often associated with stylus to the contact of touch area 1021 operates, detects stylus unlatching so preset condition can also further include or detects stylus input signal etc..Present embodiment is not particularly limited preset condition, as long as preset condition is made based on touch-control input information and frame touch information.
The present embodiment is in terms of existing technologies, the touch-control on touch area by detecting touch panel inputs the frame touch information in information and frame region, the touch operation that whether there is while touching in touch area and frame region can be quickly detected, and masks while touching the touch operation in touch area and frame region.Since present embodiment determines whether it is edge maloperation in touch area and frame region based on whether the touch location of touch operation touches simultaneously, so for the shape of detection touch operation and area, calculating can be significantly simplified, detection efficiency is improved.Therefore, present embodiment it is quick, accurately detect edge maloperation on the basis of, advantageously reduce edge false triggering, improve user's input efficiency.

Wherein, the structure of the first driving sensing unit 1013 is well known to those skilled in the art, and details are not described herein again.
It is noted that the first driving sensing unit 1013 is different from the second driving exciting signal frequency of sensing unit 1014, in this way, frame detection unit 1024 and touch control detection unit 1023 will not generate mutually interference when working at the same time.As a kind of alternative, the first driving sensing unit 1013 and the second driving sensing unit 1014 can be with asynchronous workings, so that will not interfere with each other between frame detection unit 1024 and touch control detection unit 1023.
It should be noted that, in practical applications, shielded layer or shielded wire can also be set between frame detection unit 1024 and touch control detection unit 1023, in this way, frame detection unit 1024 can be worked asynchronously with touch control detection unit 1023 with identical driving frequency, to will not interfere with each other.
The capacitance detecting leads of the frame detection unit of the present embodiment are located on the outside of touch area, therefore, it can be when any position of frame region be touched by the capacitance detecting leads for being arranged a small amount of, detect that frame region is touched, and it is possible to realize the driving to frame detection unit by the same driving sensing unit or independent driving sensing unit (the i.e. second driving sensing unit).
The present embodiment is in terms of existing technologies, frame detection unit is added by the frame region in touch panel to detect whether frame region is touched, judge whether it is edge maloperation so as to the touch location according to touch control operation, therefore for the shape of detection touch operation and area, calculating can be significantly simplified, detection efficiency is improved.
The application 3rd embodiment is related to a kind of touch device, the present embodiment can be used as the alternative embodiment of second embodiment, the main distinction of the present embodiment and second embodiment is, in a second embodiment, each capacitance detecting leads in frame detection unit are located on the outside of touch area, any position in i.e. entire frame region, for example it is located at the left side, the right, top, following edge touch can be measured by same or same group of ring-type capacitance detecting leads, and in the third embodiment, frame detection unit includes multiple capacitance type sensors, and each capacitance type sensor can detect frame region different location.
The structural schematic diagram of touch panel shown in Figure 11 is please referred to, frame detection unit includes Q touch sensor 10243, and Q is the natural number more than or equal to 2.Q touch sensor is distributed on the different location of frame region 1022, and is respectively used to whether detection different location is touched.
In practical applications, touch sensor can connect to the driving channel of touch controller and induction channels to form Q self-tolerant sensor, or, Q touch sensor a portion is connected to driving channel, another part therein is connected to induction channels, to form at least one mutual capacitance type sensor.As the quantity of touch sensor is more, the precision of the touch location for the frame region 1022 that touch controller is able to detect that is higher.For example, four bezel locations of upper and lower, left and right of frame region 1022 etc. are provided with multiple touch sensors (small box indicates touch sensor in Figure 11).In this way, can detecte when multiple positions of frame region 1022 are touched simultaneously to.In one example, frame detection unit includes 4 touch sensors, 4 touch sensors are separately positioned on four sides of upper and lower, left and right of frame region etc., and whether each side for being respectively used to detection frame region is touched, in this way, when detecting that frame region is touched, which side that frame region can be told is touched, since each side of frame region can individually detect touch, so whole edge maloperations can be more precisely detected when edge maloperation occurs simultaneously on multiple sides.For example, further can detect most 2 frame touchs according to the screen volume data on touch area when 2 different locations in frame region detect touch.
The present embodiment is touched by the different location that the touch sensor of different location distinguishes frame region, so as to more quickly and accurately shield whole edge maloperations when simultaneously edge maloperation occurs for multiple positions of frame region.
The application fourth embodiment is related to a kind of touch control terminal, such as tablet computer, smart phone, vehicle carried video etc..The touch control terminal of the present embodiment includes the touch device and primary processor as described in second or 3rd embodiment.
Wherein, touch controller can be used for shield detection to the edge maloperation for meeting preset condition, alternatively, touch-control input information and frame touch information reporting that touch controller is used to be obtained be to primary processor, the edge maloperation arrived for primary processor shield detection.
The touch control terminal of the present embodiment can be by the frame touch information in detection frame region, and touch-control on combination of touch control region inputs information, more quick or accurately detect edge maloperation, to be conducive to raising user's input efficiency.
The 5th embodiment of the application is related to a kind of touch control method, applied to touch control terminal as described in the fourth embodiment, such as tablet computer.
The flow chart of touch control method shown in Figure 12 is please referred to, which includes:
Step 201: obtaining the touch-control input information of touch area and the frame touch information of frame region.
Wherein, touch-control inputs information for example, touch-control input information, the touch-control input information of user's finger and other touch-control that can detecte inputs information (such as touch information of palm) of stylus.Frame touch information for example, frame region is touched or frame region is not touched.In one example, frame touch information can also include: the touching position information of frame region, for example, frame region the left side or the right touched, simultaneously, the quantity that can also be operated according to frame touch acquisition of information frame touch, such as 0,1 or 2 etc..Specifically, frame region is equipped with multiple touch sensors, touch sensor can be evenly distributed on frame region, or it according to actual needs or dredges or is thickly distributed in frame region, so as to detect the touch information of different location in frame region, for example, when left-hand palm touches on the left side of the frame region of tablet computer, and right hand palm is touched at the right of frame region, just produces 2 frame touchs.
Step 202: information and frame touch infomation detection being inputted with the presence or absence of the edge maloperation for meeting preset condition according to touch-control, if detecting edge maloperation, execute step 203, otherwise return step 201.
Specifically, edge maloperation refers to the desired touch operation of non-user occurred at touch area edge.Specifically, such as when being inputted using stylus, the palm of user may rest on touch area, and the touch operation non-user of palm it is expected, be likely to result in touch control terminal and accidentally respond.When palm rests on the near center location of touch area, since the shape and area of palm are significantly greater than finger, so by obtaining screen volume data (such as the shape and area touched on touch area), and the touch shape and area that will acquire are compared with preset shape and area (such as shape and area of finger), that is, may recognize that and shield volume data caused by touching due to palm；When the edge of palm to touch area is mobile and rests on the shape of touch area edge and area and the close finger of user, then it is difficult to for palm data being at this time distinguished with finger data (i.e. finger touches the screen volume data generated).Therefore, for area is greater than the palm of finger, touch-control input information (such as screen volume data of palm generation) on combination of touch control region and the frame touch information (such as whether frame is touched) in frame region, it can more precisely identify and shield volume data caused by being touched by palm.Specifically, preset condition is, for example, while touching in touch area and frame region, for the touch control terminal (such as tablet computer) bigger than normal for screen body size, since user's finger touches simultaneously, the chance that the chance of touch area and frame region is touched more than palm simultaneously in touch area and frame region is few, and the operation for touching simultaneously in touch area and frame region, which is considered as edge maloperation, can reduce terminal accidentally response.
In the present embodiment, information is inputted according to touch-control and frame touch infomation detection meets the edge maloperation of preset condition for example, is operated according to whether there is frame touch in frame touch infomation detection frame region, frame touch operates if it exists, the edge maloperation that infomation detection meets preset condition is then inputted according to touch-control, frame touch operates if it does not exist, it then can quickly judge that there is no edge maloperations, return to step 201.
In one example, it is specifically included according to the edge maloperation that touch-control input infomation detection meets preset condition: the quantity of frame touch operation is obtained according to frame touch information, edge maloperation is detected according to the quantity of frame touch operation.Such as, when judging that the quantity of frame touch operation is 1 according to frame touch information, then inputting information according to touch-control judges touch area with the presence or absence of multiple touch operations, 1 touch operation if it exists, it then can directly judge the touch operation for edge maloperation, multiple touch operations if it exists then can input information according to touch-control and further analyze the touch location of each touch operation, to filter out while touch 1 edge maloperation in touch area and frame region.
When detecting the operation of 2 frame touchs, and only there are two when touch according on touch-control input infomation detection to touch area, two touches that can judge touch area are edge maloperation, if detecting, there are when 3 touches on touch area, then 2 edge maloperations and 1 normal touch operation further can be distinguished according to screen volume data, therefore, whole edge maloperations can be fast and accurately identified according to frame touch quantity.
In practical applications, in order to more accurately identify edge maloperation caused by palm etc., preset condition can also be while touch the touch area in touch area and frame region and on touch area greater than preset threshold, preset threshold is, for example, the area of user's finger, in this way, since finger is touched at touch area and frame region simultaneously, the touch area touched on touch area can become smaller, so can more precisely identify palm while touch in touch area and frame region and caused edge maloperation when touching touch area of the area close to finger.In some instances, the difference of other operating main bodies and finger size can also be utilized, to identify its edge maloperation caused by the edge of touch area, present embodiment is not particularly limited for touching main body and preset condition.
Step 203: the edge maloperation that shield detection arrives.
Specifically, if touch controller detects edge maloperation, then touch controller does not report the coordinate of the edge maloperation to primary processor, if primary processor detects the edge maloperation, primary processor does not report the corresponding coordinate of edge maloperation to application program or operating system.
The touch control terminal of the present embodiment can be by the frame touch information in detection frame region, and touch-control on combination of touch control region inputs information, more quick or accurately detect edge maloperation, to be conducive to raising user's input efficiency.
The application sixth embodiment is related to a kind of touch control method, makes improvement on the basis of five embodiments, further defines the testing conditions of edge maloperation.
It please refers to shown in Figure 13, the touch control method of the present embodiment includes step 301 to step 304.Wherein, step 301 is identical as step 201, step 303,304 identical as step 202,203 correspondences, and details are not described herein again.
Step 302: judging whether touch-control input information includes stylus input information, if continuing to execute step 303 including stylus input information, if not including stylus input information, return step 301.
The present embodiment is compared with sixth embodiment, since the input that palm is often associated with stylus to the contact of touch area operates, so the present embodiment is when detecting that stylus inputs information, show that user is using stylus, at this time by executing step 303,304, edge maloperation caused by palm can be effectively shielded, when stylus is not used in user, step 303 and step 304 are not executed, system power dissipation is advantageously reduced.It will be understood by those skilled in the art that the various embodiments described above are to realize the specific embodiment of the application, and in practical applications, can to it, various changes can be made in the form and details, without departing from spirit and scope.
