Description

Touch device and object determining method for touch device

The present invention relates to a touch device, and more particularly to a touch device for performing object determination on a touch panel and having the touch panel.

At present, many portable electronic devices use a touch interface. The touch interface is gradually developed into a multi-touch by the traditional single-touch and dual-touch functions in a wider variety of applications and objects. Further providing the function of object recognition. Taking a smart phone as an example, after selecting an incoming call, the touch interface will be in contact with the user's ear. In this case, the smart phone is required to judge that the touch interface is in contact with the user's ear (answering During a call) or perform other function fingers.

The object judgment function is currently implemented on a two-dimensional touch panel, and the projected capacitive touch panel is a type of a two-dimensional touch panel. The projected capacitive touch panel is mainly a multi-channel process on a substrate. Forming an X-axis sensing layer, an insulating layer, a bridge, a Y-axis sensing layer, etc., respectively, forming a symbiotic capacitance between the X-axis and the Y-axis sensing electrodes staggered and adjacently disposed on the X-axis and Y-axis sensing layers, when there is a finger or The object touch will change its capacitance value, and the controller will continuously scan each string of X-axis and Y-axis induction In order to detect the change of the capacitance value, the touch coordinates are determined; based on the above working principle, the object judgment is considered to be easier to implement on the two-dimensional touch panel.

However, it is technically difficult to determine the object in the one-dimensional touch panel. A known one-dimensional touch panel is as shown in FIG. 8 , and is mainly formed on a substrate 80 in a horizontal direction and formed with a plurality of strips. Each of the sensing electrodes 81 is composed of two triangular left electrode portions 811 and right electrode portions 812 arranged in a complementary direction; and the sensing amount of each sensing electrode 81 is used to determine the position touched by the user. Then perform the corresponding function.

Since the one-dimensional touch panel supports only two touches at most, and the two touch positions cannot be located on the same sensing electrode 81, it will not be recognized. Since the supported multi-touch function has been extremely limited, let alone the judgment of the object in the one-dimensional touch panel.

The invention patent of the "FAR-FIELD INPUT IDENTIFICATION" is disclosed in the prior art, mainly in view of the existing touch or proximity sensor, and its support. Soft and hard objects are not able to provide the shape of the identification contact or proximity object, thus providing a method for identifying but not touching objects on a multi-touch touch-surface for detecting on the touch panel. A non-hover object (such as an ear or a cheek) is measured; a specific method is to generate a far-field image from the proximity image after obtaining a proximity image. The far-field image image value is generated by combining the far-field image pixels corresponding to the background pixels close to the image, and when the far-field image value is higher than the threshold value, the object is determined to be hovering on the touch panel. If It is the function of starting the electronic device. The specific application can judge the ear and cheek of the handset on the mobile phone on the smart phone to control the specific function items on the smart phone.

The identification of the object in the aforementioned U.S. Patent is mainly based on the proximity image being substantially elliptical. Therefore, the far-field image value can be determined by using the short axis of the major axis and the minor axis (major/minor radii) as a parameter. Above the threshold. In other words, the identification of the far-field image by the aforementioned US Patent Publication is still implemented on a two-dimensional basis, and the calculation method is complicated. As mentioned above, the one-dimensional touch panel has many limitations on the support of two-point touch, let alone the identification of objects; and the identification of non-contact objects proposed by the aforementioned US Patent Publication for one-dimensional In terms of touch panels, the technology needs to be broken.

It can be seen from the above that the object judgment gradually becomes a necessary function for the touch interface. The two-dimensional touch panel is easy to implement for object judgment, but usually involves a complicated algorithm; and the one-dimensional touch panel supports only two at most in the prior art. Point touch, let alone judge the object.

Therefore, the main purpose of the present invention is to provide a method for determining an object applied to a touch device, which can be applied to a one-dimensional and two-dimensional touch panel, so as to break through the bottleneck of the one-dimensional touch panel that cannot effectively identify the object, and can also solve the problem. The two-dimensional touch panel judges the complexity of the object calculation.

The main technical means for achieving the foregoing objective is to enable the foregoing method to include the steps of: detecting the sensing quantity of each sensing electrode of a sensing layer; and determining the sensing having a maximum sensing quantity from the measured sensing quantity. The electrode defines a detection area, and the detection area includes one or more sensing electrodes adjacent to the sensing electrode having the largest sensing amount; comparing the maximum sensing amount with the sensing amount of one or more sensing electrodes in the detecting area, if the maximum When the ratio of the sensing amount to the sensing amount of one or more sensing electrodes in the detecting area is less than a first set value, it is regarded as a first object being recognized.

In the foregoing method, the sensing quantity change between adjacent sensing electrodes on the touch device is used as the identification basis of an object, thereby achieving the purpose of identifying the object on the touch panel.

It is still another object of the present invention to provide a touch device that can recognize an object.

The main technical means for achieving the foregoing objective is that the touch device comprises: a touch panel, which is mainly provided with a first sensing layer on a substrate, and the first sensing layer is formed on the surface of the substrate by a first The plurality of sensing electrodes are arranged side by side, wherein a plurality of adjacent sensing electrodes form an object sensing area; and a controller is electrically connected to each sensing electrode of the first sensing layer disposed on the touch panel to detect The sensing quantity of each sensing electrode is determined by the sensing quantity in the sensing area of the object to determine a sensing electrode having a maximum sensing quantity, thereby defining a detection area adjacent to the maximum sensing quantity sensing electrode, when the maximum A first object is identified when the amount of change between the amount of sensing and the amount of sensing of one or more sensing electrodes in the detecting area is less than a first limit value.

The controller of the touch device detects the inductive power in the sensing area of the object The amount of inductance is measured according to the maximum amount of sensing and the amount of change of the sensing amount of one or more sensing electrodes in a detecting area; whether the object is an object; and the above technology is used to implement the one-dimensional or two-dimensional touch panel. The object judgment enables the touch device to provide a more flexible and convenient control function item by using the object judgment function.

For a preferred embodiment of the method for determining the object of the touch device of the present invention, first, referring to FIG. 1 , the touch device includes a touch panel, and the touch panel is mainly a substrate 10 . A first sensing layer 20 is disposed on the surface, and the first sensing layer 20 is mainly composed of a plurality of sensing electrodes 21 arranged along a first direction on the surface of the substrate 10. Formed and used to form a one-dimensional touch interface. The sensing layer 20 can be composed of sensing electrodes of various shapes. As shown in FIG. 1 , the sensing electrodes 21 constituting the first sensing layer 20 are respectively composed of a left electrode portion L01 L12 and a right electrode portion R01 R12. In the composition, the left and right electrode portions L01 to L12 and R01 to R12 are opposite triangles, which are staggered in a complementary direction in which the oblique sides face each other. Referring to FIG. 2, another shape of the sensing electrode of the one-dimensional sensing layer is disclosed. The sensing electrodes 21 are respectively formed by electrodes of a single rectangular strip shape. The above two sensing layer shapes are merely examples, that is, the first sensing layer 20 referred to in the present invention includes, but is not limited to, the foregoing two forms. For convenience of description, the working principle of the object determining method of the present invention will be described below with respect to the first sensing layer 20 shown in FIG. 1. The left and right electrode portions L01~L12 and R01~ of the sensing electrodes 21 in the first sensing layer 20 are described. R12 will be respectively connected to a controller (not shown), and the controller determines the sensing amount (dS) of each sensing electrode 21, and then determines the object according to the change of the sensing amount.

The sensing amount of each sensing electrode 21 is obtained by: dS _n =dV _Ln +dV _Rn where dV _Ln is the capacitance sensing value of the left electrode portion of a sensing electrode, and dV _Rn is the right electrode portion of the same sensing electrode The capacitance sensing value, the sensing amount of the sensing electrode is the sum of the capacitance sensing values of the left and right electrode portions.

A preferred embodiment of the method for determining an object of the present invention is mainly performed by the controller (refer to FIG. 3 and FIG. 4): detecting the sensing quantity (401) of each sensing electrode 21, and each sensing electrode The sensing quantity dS of 21 is shown in Figure 3, and the horizontal axis indicates each sensing. The electrode 21 is respectively L01+R01, L02+R02, L03+R03, L04+R04, L05+R05, L06+R06, L07+R07, L08+R08, L09+R09, L10+R10, L11+R11, L12+R12 is shown; the vertical axis indicates the amount of inductance dS of each of the aforementioned sensing electrodes 21.

The sensing electrode (402) having a maximum sensing amount is determined from the measured sensing electrode, and is defined as a target sensing electrode; according to FIG. 3, the second sensing electrode (L02+R02) has The maximum sensing amount dS2, so the second sensing electrode (L02+R02) is the target sensing electrode.

Then, a detection area (403) is defined, which is mainly defined as one detection area 22 adjacent to the sensing electrode (L02+R02) having the maximum sensing quantity dS2. Please refer to FIG. 1 and FIG. 3 together. The detection area 22 theoretically includes more than one sensing electrode after the third sensing electrode (L03+R03) (such as L04+R04, L05+R05 or L06+R06, etc.), due to object proximity or touch touch. In the panel, in addition to sensing the sensing electrode at the predetermined touch position, there is a very large possibility that the adjacent sensing electrode will generate a large amount of inductance at the same time. To eliminate the malfunction, the sensing electrode with the maximum sensing amount dS2 will be ignored (L02). +R02) the adjacent sensing electrode (L03+R03), that is, the detecting area 22 does not include the sensing electrode (L03+R03) adjacent to the maximum sensing amount dS2 sensing electrode (L02+R02); according to the maximum sensing amount dS2 Comparing the amount of change (eg, difference, ratio) of the sensing quantity of one or more sensing electrodes in the detecting area 22 to identify a first object; in this embodiment, comparing the maximum sensing quantity dS2 with the detecting area 22 The sensing amount of one or more sensing electrodes (404), and determining the maximum sensing amount dS2 The detection area 22 a quantity of more sensing sensing electrodes When the amount of change is less than a first limit value, it is regarded as a first object is recognized; assuming that the first limit value is 800, when the maximum sensed amount dS2 and the sensing amount of one or more sensing electrodes in the detecting area 22 When the amount of change between them is less than 800, a first object is recognized. If the amount of change is greater than 800, then a second object is considered to be recognized (405).

In order to ensure the accuracy of the first object identification, in the embodiment, when the change amount is less than the first limit value, it is further determined whether the change amount is smaller than a second limit value (for example, 500) (406), and if so, the first judgment is made. An object is identified (407).

The sensing amount of the detecting area 22 may be an induction amount of a single sensing electrode, or may be an average of the sensing amount or the sensing amount of two or more sensing electrodes.

A further preferred embodiment of the method for determining the object of the present invention, as shown in FIG. 5, includes: detecting the amount of induction of each of the sensing electrodes 21 (501); determining from the sensing electrodes that have been measured to have an amount of sensing The sensing electrode (502) having a maximum sensing amount; defining a detecting area (503), mainly defining one or more sensing electrodes adjacent to the sensing electrode (L02+R02) having the maximum sensing amount dS2 as a detecting area 22: Comparing the maximum sensing amount dS2 with the sensing amount of one or more sensing electrodes in the detecting area 22 (504), and determining the maximum sensing amount dS2 and the sensing amount of one or more sensing electrodes in the detecting area 22 When the ratio Q is less than a first set value (for example, 8), it is regarded as a first object is recognized; when the ratio Q is not less than the first set value, it is regarded as a second object The piece is identified (505).

In order to ensure the accuracy of the first object identification, in the embodiment, when the ratio Q is smaller than the first set value, it is further determined whether the ratio Q is smaller than a second set value (for example, 3) (506), and if so, the first judgment is made. An object is identified (507).

In the foregoing embodiment, a larger first set value and a smaller second set value are taken, and it is sequentially determined whether the ratio Q is smaller than the first set value and smaller than the second set value to determine the first object. Identification. However, in addition to the above, the present invention may take a larger second set value (e.g., 8 or more) and a smaller first set value (e.g., 3). The judgment method is also slightly different, mainly when the judgment ratio Q is smaller than the first set value, and is recognized as the first object; when the ratio Q is greater than the first set value, it is further determined whether the ratio Q is greater than the second set value, and if , the second object is identified; the above method can further improve the identification accuracy of the second object.

As for the number of sensing electrodes in the detecting area 22 and the amount of sensing thereof, the detecting unit 22 has three sensing electrodes L04+R04, L05+R05 and L06+R06, and the ratio Q is the maximum sensing amount. The sum of the sensing quantities of the three sensing electrodes L04+R04, L05+R05, L06+R06 in the dS2 and the detecting area 22 is calculated and calculated as follows:

It should be noted that one of the operational bases (denominator) of the foregoing ratio Q may be a single sensing electrode in the detecting area 22, or may be two or more sensing electrodes in the detecting area 22, for example, the foregoing three sensings. The electrode, and the sum of its inductive quantities, is used as the basis for the operational ratio Q.

The magnitude of the aforementioned ratio Q will reflect the characteristics of an object Strength and weakness, in particular, the foregoing method can identify an object that is slightly elongated across a plurality of sensing electrodes. When such objects approach or contact the first sensing layer 20, the largest one appears on one sensing electrode. The amount of induction, when ignoring a sensing electrode adjacent to the maximum sensing amount sensing electrode, and obtaining the sensing amount of the next sensing electrode or the sensing amount of the following two or more sensing electrodes, will exhibit a tendency to reduce and decrease, in this case If the ratio Q is relatively low and the object feature is relatively strong, the first object is identified when the ratio Q is smaller than the first set value (for example, the Q value is 8 or less), and if the ratio Q is greater than the first set value. , is considered a second object.

In order to ensure the correctness of the identification, if the ratio Q is smaller than the first set value, it is further determined whether the ratio Q is smaller than a second set value (for example, the ratio Q is 3 or less), and the mitigation reduction of the sensing amount can be further confirmed. Trends, while relatively improving recognition accuracy.

When the present invention uses the smaller first set value (for example, 3) and the larger second set value for object determination, when the maximum sensed amount and the sensed electrode sensing amount in the detection area 22 are suddenly decreasing, then The ratio Q is greater than the first set value, and when it is further greater than a second set value (for example, more than 8), it is regarded as a second object, which indicates that the user touch position is specific, thus making the touch other than the touch position. The amount of sudden decrease can be regarded as a general finger touch or a pen tip touch.

In the foregoing embodiments, the ratio Q is calculated by using the maximum amount of inductance as a numerator, and the sensing amount of one or more sensing electrodes in the detecting area 22 is used as a denominator, for example, the following formula:

Only when the numerator and denominator of the aforementioned ratio are inverted, for example:

Then, the identification result reflected by the ratio Q is opposite to the identification result of the foregoing embodiment; that is, the ratio Q between the maximum sensing amount and the sensing amount of one or more sensing electrodes in the detecting area 22 is greater than a first When the value is set (for example, 0.125), it is regarded as a first object is recognized; if the ratio Q is smaller than the first set value, it is regarded as a second object.

In order to ensure the identification accuracy of the first object, when the ratio Q is greater than the first set value, it is further determined whether it is greater than a second set value (0.25), and if so, the first object is determined to be recognized.

When the present invention uses a larger first set value (for example, 0.25) and a smaller second set value (0.125) for object determination, the sensing amount of the sensing electrode in the maximum sensing amount and the detecting area 22 is abruptly decreased. When the ratio Q is smaller than the first set value, and when it is further less than a second set value (for example, below 0.125), it is regarded as a second object, which indicates that the user touch position is specific, thus making the touch-free A sudden decrease in the amount of sensing outside the position can be regarded as a general finger touch or a pen tip touch.

As shown in FIG. 6 , the touch device is a mobile phone having a housing 30 on which the foregoing touch panel is disposed, and An earpiece 31 and a microphone 32 are respectively disposed at the upper and lower ends; and the sensing layer 20 on the touch panel constitutes an object sensing area 33 by a plurality of sensing electrodes 21 adjacent to the earpiece 31, and the controller is in the object sensing area 23 Perform the aforementioned object determination method.

In the application embodiment, the first sensing layer 20 is close to the outside. The object sensing area 23 of the earpiece provided on the casing 30 can be used to replace the light sensor provided by the traditional smart phone at the periphery of the earpiece, and the light sensor is used to answer the phone with the ear or cheek close to the mobile phone, and When the photo sensor is covered, the touch and/or backlight function of the mobile phone will be turned off. After the present invention replaces the photo sensor with the object sensing area 23, the controller determines the sensing electrode having a maximum sensing amount from the measured sensing quantity in the object sensing area 23, and defines the After the detection area adjacent to the maximum sensing quantity sensing electrode is further determined that the maximum sensing amount and the amount of change of the sensing quantity of one or more sensing electrodes in the detecting area are less than a first limit value (for example, 800), the first identification value is recognized. When an object is seen as being close to the ear, the first function item is executed to turn off the backlight and/or touch function. When the user has an input demand during the call, when the finger touches the touch panel, the controller determines that the maximum amount of sensing and the amount of change of the sensing amount of one or more sensing electrodes in the detecting area are further greater than the first limit value. When the second object is identified, the first function item is released and the backlight function of the mobile phone is restored.

When the invention is implemented on a mobile phone, the identification of the hover object can be further realized on the one-dimensional touch panel, and a proximity sensor is provided.

In order to achieve the above functions, the controller further causes the controller of the touch device to detect the sensing amount of each sensing electrode in the sensing area 23 of the object by a first signal intensity, and when the controller recognizes the second object, it is smaller than the first The second signal intensity of the signal intensity scans the respective sensing electrodes within the object sensing area 23. Since the controller first detects the sensing amount of the object sensing area 23 with a strong first signal intensity, when the user's ear is close to the touch panel, the sensing electrode in the object sensing area 23 is induced. Amount, according to which the identification of the unhooked object is achieved. If the controller recognizes the second object (finger), the touch function can be performed normally only by detecting the amount of the sensor with the normal signal intensity.

The foregoing embodiments are primarily illustrative of how the present invention utilizes a one-dimensional touch panel. In addition to the one-dimensional touch panel, the present invention can also be applied to a two-dimensional touch panel to provide a relatively simple object judgment technique for the two-dimensional touch panel. Referring to FIG. 7 , a projected capacitive touch panel is mainly provided with a first sensing layer and a second sensing layer respectively on a substrate 40 , and the second sensing layer is formed by a plurality of substrates on the substrate. The first sensing layer is composed of a plurality of parallel sensing electrodes arranged side by side in parallel; in the embodiment, the first sensing layer is composed of a plurality of X-axis sensing electrodes 41 arranged side by side along the X-axis direction on the substrate 40, and the second sensing layer is Then, a plurality of Y-axis sensing electrodes 42 are arranged in parallel along the Y-axis direction on the substrate 40, and the Y-axis sensing electrodes 42 respectively intersect the X-axis sensing electrodes 41 at right angles. The X-axis and Y-axis sensing electrodes 41 and 42 are respectively connected to a controller (not shown) for detecting the amount of inductance of each of the X-axis and Y-axis sensing electrodes 41 and 42.

The sensing layer referred to in the foregoing object determining method may be the first sensing layer or the second sensing layer in this embodiment. For convenience of description, the first (X-axis) sensing layer is taken as an example to illustrate its operation. Method: The touch panel mainly comprises a plurality of adjacent X-axis sensing electrodes 41 on the substrate 40 to form an object sensing area thereof, and the controller sends driving signals to the X-axis sensing electrodes 41, and is also controlled by the X-axis sensing electrodes. 41 receives the signal to detect the amount of sensing, that is, the scanning mode of the touch panel is self-contained. According to the above operation mode, the controller can further perform the objects shown in FIG. 4 and FIG. 5 after detecting the sensing amount of each of the X-axis sensing electrodes 41. Piece judgment method. In other words, the object determining method of the present invention can also be applied to a two-dimensional touch panel. When the present invention is applied to a two-dimensional touch panel, compared with an object determining method of the existing two-dimensional touch panel, The general is relatively simple.

As can be seen from the above, the present invention can detect the sensing quantity of each sensing electrode on the sensing layer on the touch panel, and realize the object according to the maximum sensing amount and the amount of change of the sensing quantity of one or more sensing electrodes in a detecting area. Identification; when using a one-dimensional touch panel, it will make a major breakthrough in the identification technology of the one-dimensional touch panel; when used in the two-dimensional touch panel, it can provide a relatively simple identification technology; In addition to the object control function to provide more flexible and convenient control function items, the identification of untouched objects can be further provided, and the control mode of the touch panel can be further improved.
