technical field

The present invention relates to a touch sensor technology, and in particular to a touch sensor style adjustment method and an electronic device.

Background technique

With the development of touch panel technology, touch panels have been widely used in screens of electronic devices, such as mobile phones, notebook computers or tablet computers. The touch panel can allow users to perform input or operation actions more conveniently, making its user interface more humanized and convenient.

Generally speaking, a touch panel has a plurality of touch sensors disposed on a substrate. When the user's hand or the touch input device touches the touch panel, the sensing quantities sensed by the touch sensors will change. Therefore, the touch chip connected to these touch sensors can determine the position actually touched by the user according to the sensing values detected by the touch sensors. However, based on the convenience of operation and use, the nib area of the stylus is designed to be smaller and smaller. Therefore, as the contact area shrinks, the number of touch sensors capable of sensing changes caused by the touch of the stylus decreases accordingly, resulting in a decrease in the accuracy of touch detection.

In the existing methods, the accuracy of touch detection can be improved by reducing the size of the touch sensor and increasing the sensing channels. However, if the number of sensing channels is to be changed, the touch chip of the touch panel needs to be replaced, which will increase the manufacturing cost of the touch panel. Furthermore, the size of the touch sensor is usually limited by the number of channels of the touch chip or the characteristics of the elements of the touch sensor, so it cannot be reduced indefinitely. Therefore, how to improve the above problems as much as possible while taking into account the cost, the accuracy of touch detection and the compatibility with existing products is actually one of the topics that those skilled in the art are devoted to research.

The style adjustment method includes the following steps. Collect the panel information of the touch panel. An initial layout result of the touch sensor is generated according to the panel information and the preset sensor information, wherein the preset sensor information includes the initial sensor pattern. The non-coverage area of the touch sensor on the touch panel is obtained by analyzing the initial layout result. Extending the coverage of the initial sensor pattern over the non-coverage area to generate at least one extension region to obtain a final sensor pattern having at least one extension region.

From another point of view, the present invention provides an electronic device for determining sensor patterns of a plurality of touch sensors of a touch panel.

The analysis module analyzes the initial layout result to obtain the non-coverage area of the touch sensor on the touch panel. The extension module extends the coverage of the initial sensor pattern above the non-coverage area to generate at least an extension area to obtain a final sensor pattern with at least one extension area.

Based on the above, the embodiment of the present invention extends the coverage of the touch sensor by changing the sensor style, so as to increase the sensing range of a single touch sensor, thereby improving the accuracy of determining the position of the touch point.

detailed description

The touch panel has a plurality of touch sensors to sense the user's touch operation, and the touch chip will locate the contact position of the touch operation according to the sensing results of the touch sensors. Generally speaking, if there are more touch sensors that can detect sensing values, the amount of information that can be used for positioning is relatively large, so the positioning accuracy of touch points can be improved. According to the present invention and this feature, new sensor styles can be generated through analysis and design before the actual touch panel is manufactured and etched. In this way, the preset sensor pattern can be extended to expand the sensing range of each touch sensor and reduce the phenomenon of poor positioning accuracy in some areas. In order to make the content of the present invention clearer, the following examples are listed as examples in which the present invention can actually be implemented.

FIG. 1 is a block diagram of an electronic device according to an embodiment of the invention. Please refer to FIG. 1, the electronic device 10 of this embodiment is a computing device with computing functions, such as a desktop computer, a notebook computer or other computer structures, which includes a storage unit 14 and one or more processing units 16, and its functions are described in detail. as follows:

The storage unit 14 is, for example, any form of fixed or removable random access memory (Random Access Memory, RAM), read-only memory (Read-Only Memory, ROM), flash memory (Flash memory), hard disk or other similar devices or these The combination of devices is used to record a plurality of modules that can be executed by the processing unit 16, and these modules can be loaded into the processing unit 16 to execute the method for adjusting the style of the touch sensor.

The processing unit 16 is, for example, a central processing unit (Central Processing Unit, CPU), or other programmable general purpose or special purpose microprocessor (Microprocessor), digital signal processor (Digital Signal Processor, DSP), programmable controller , Application Specific Integrated Circuits (ASIC), Programmable Logic Device (Programmable Logic Device, PLD) or other similar devices or a combination of these devices. The processing unit 16 is coupled to the storage unit 14 and can access and execute modules recorded in the storage unit 14 .

The above-mentioned modules include an information collection module 142, an initial configuration module 144, an analysis module 146, and an extension module 148. These modules are, for example, computer programs that can be loaded into the processing unit 16 to analyze and further adjust the sensor pattern of the touch sensor to Decide on a better sensor pattern before proceeding with the etch process of the touch panel. The following is an example to illustrate the detailed steps of the method for adjusting the style of the touch sensor.

It should be noted that the touch panel described in this embodiment can detect a user's contact operation (contact operation), and generate corresponding touch point information according to the detected contact operation. The touch operation is, for example, that the user touches the touch panel through an input tool (for example, a finger or a stylus), so as to issue an instruction to a device equipped with the touch panel through the touch panel. In order to generate corresponding touch point information in response to the user's contact, the touch panel has a plurality of touch sensors.

In addition, the touch panel may be a resistive touch panel or a capacitive touch panel, and the present invention is not limited thereto. Among them, different types of touch panels will have different types of touch sensors. For example, resistive touch panels will use the resistance value formed by the user to touch the touch panel to detect touch points, while capacitive touch panels The touch point is detected by the capacitance formed by the user touching the touch panel. Wherein, taking a capacitive touch panel as an example, these touch sensors include sensing electrodes for sensing capacitance, and the material of these sensing electrodes is, for example, indium tin oxide (ITO). In this embodiment, the patterns of these sensing electrodes are regarded as sensor patterns, and the sensing range of the touch sensor will vary with different sensor patterns.

Furthermore, the touch sensors described in this embodiment are arranged on channels and connected in series to form a plurality of sensing series. When a user's finger is placed on the touch panel, the sensing electrodes directly below and adjacent to the finger will sense, for example, changes in capacitance or other sensing parameters due to the contact of the finger. Based on this, the touch chip of the touch panel can obtain the relevant position information of the touch points according to the sensing results of these sensor series. Wherein, in the touch panel described in this embodiment, the structure of the sensing series may be a single layer or double layer structure.

FIG. 2 is a flow chart of a method for adjusting a style of a touch sensor according to an embodiment of the present invention. Please refer to FIG. 2 , the detailed steps of the method for adjusting the style of the touch sensor of the present invention will be described below in combination with various components in the electronic device 10 .

First, in step S210 , the panel information of the touch panel is collected by the information collection module 142 . The touch panel described in this embodiment has a touchable area and a plurality of sensing channels, and these touch sensors are arranged in the sensing channels to form a plurality of sensing series. The panel information includes the block size of the touchable area and the number of sensing channels of the sensing channels. In step S230 , the initial configuration module 144 generates the initial layout results of the touch sensors according to the panel information and the preset sensor information, wherein the preset sensor information includes the initial sensor pattern.

Specifically, in one embodiment, the information collection module 142 collects, for example, the block size of the touchable area and the number of sensing channels of the sensing channels. Based on the above knowledge, the touch chip of the touch panel determines the number of sensing channels of the touch panel. Therefore, when the manufacturer of the touch panel decides the touch chip, the number of sensing channels of the touch panel also depends on it. Furthermore, the manufacturer of the touch panel will also determine the block size of the touchable area of the touch panel according to practical or design requirements.

Afterwards, the initial configuration module 144 generates initial layout results of the touch sensors according to the panel information and preset sensor information. Furthermore, the manufacturer of the touch panel will also determine the preset sensor information according to practical or design requirements. The preset sensor information includes design information such as initial sensor style, sensor spacing, sensor size, and sensor charging and discharging time. The initial sensor pattern is, for example, a diamond pattern (Diamond pattern), a strip pattern (Stripe pattern) or a snowflake pattern (Snowflake pattern), which is not limited here. The sensor spacing represents the distance between adjacent sensors, the sensor size represents the size of a single touch sensor, and the charging and discharging time of the sensor represents the time required for the capacitive touch sensor to charge and discharge.

Therefore, based on the panel information and the preset sensor information, the initial configuration module 144 can generate an initial layout result of the touch sensors. For example, FIG. 3 is a schematic diagram of a touch panel according to an embodiment of the present invention. Please refer to FIG. 3 , in this example, the touch panel 300 includes a touch chip 320 and a touchable area A. As shown in FIG. The block size of the touchable area A is shown in FIG. 3 , and the block size of the touchable area A is the area width L1 and the area length L2 . Furthermore, the touch chip 320 determines the number of channels of the touch panel 300 . In this example, the touch panel 300 has a channel number N, which means that the touch panel 300 has N sensing channels, where N is a positive integer.

That is to say, in this example, the information collection module 142 will collect panel information including the block size of the area width L1 and the area length L2 and the number of channels N. In addition, in this example, the initial sensor pattern is a rectangular pattern (Rectangular pattern), and the distance between adjacent sensors is the sensor pitch SL1. Furthermore, the touch sensor has a sensor size of a sensor length P1 and a sensor width P2.

In this way, the initial configuration module 144 can generate the touch sensor P_11 according to the block size of the area width L1 and the area length L2, the number of channels N, the rectangular pattern, the sensor pitch SL1, and the sensor size including the sensor length P1 and the sensor width P2 ~ Initial layout result of P_MN. In this example, the initial layout result is shown in FIG. 3 , there are N sensing channels C1 -CN in the touchable area, and touch sensors P_11 -P_M1 are disposed on the first channel C1 . By analogy, touch sensors P_1N˜P_MN are configured on the Nth channel CN. It should be noted that FIG. 3 is only an exemplary example, and is not intended to limit the present invention. In a word, the initial configuration module 144 can configure the touch sensors on the touch panel according to the panel information and preset sensor information.

It can be known that due to the limitation of the number of channels of the touch chip, if the touchable area of the touch panel is larger, the distance between the channels will be relatively larger. However, for the size of the touch sensor, there are other related limitations, which prevent unlimited enlargement. For example, if the number of channels is reduced but the size of the touch sensor is too large, for a touch input device with a small contact area, the number of touch sensors for the touch panel to sense the touch of the stylus will be relatively reduced. As a result, the accuracy of touch detection decreases accordingly. Therefore, the present invention will further change the style of the touch sensor according to the area not covered by the touch sensor.

Returning to the flow of FIG. 2 , in step S250 , the analysis module 146 analyzes the initial layout result to obtain the non-coverage area of the touch sensor on the touch panel. That is to say, after the initial configuration module 144 completes the layout of the touch sensors, the analyzing module 146 can know the non-coverage area on the touch panel that is not covered by the touch sensors according to the current initial layout result.

For example, FIG. 4A and FIG. 4B are schematic diagrams illustrating an example of analyzing a non-coverage area according to an embodiment of the present invention. Please refer to FIG. 4A. For the convenience of describing the present invention, assume that the initial layout result is as shown in FIG. touch sensor. Furthermore, there are touch sensors 411 - 413 on the sensing channel F1 , and touch sensors 414 - 415 on the sensing channel F4 . However, although this example is shown in FIG. 4A , FIG. 4A is only an exemplary example and is not intended to limit the present invention.

Further, the analysis module 146 defines the no-coverage area by, for example, the endpoint positions of each touch sensor. As shown in FIG. 4A , the analyzing module 146 can record the positions of the endpoints of each touch sensor. For example, the analyzing module 146 can record the position information of the endpoint a, the endpoint b, the endpoint c and the endpoint d of the touch sensor 411 . Therefore, the analysis module 411 can know that the diamond-shaped area formed by the endpoint a, the endpoint b, the endpoint c, and the endpoint d is the coverage area covered by the touch sensor 411 , otherwise it is the non-coverage area not covered by the touch sensor 411 . Therefore, after analyzing the positions of the endpoints of the plurality of touch sensors, the analysis module 146 can obtain the non-coverage area non_c1 on the touch panel not covered by the touch sensors by intersecting the non-coverage areas of the touch sensors.

In addition, in another embodiment, the analysis module 146 can also analyze the non-coverage area according to the edge of the touch sensor. Please refer to FIG. 4B , for the convenience of describing the present invention, assume another initial layout result as shown in FIG. 4B , the touchable area A2 has sensing channels G1 - G2 and a plurality of touch sensors in a rectangular shape. Furthermore, there are touch sensors 416 - 417 on the sensing channel G1 , and touch sensors 418 - 419 on the sensing channel G2 . However, although this example is shown in FIG. 4B , FIG. 4B is only an exemplary example and is not intended to limit the present invention.

Here, the analysis module 146 defines the no-coverage area by, for example, the edge of each touch sensor. As shown in FIG. 4B , the analysis module 146 can record edge information of each touch sensor. For example, the analysis module 146 can record the upper edge e, lower edge f, left edge g, and right edge h of the touch sensor 411 . Therefore, the analysis module 411 can know that the rectangular area cut out by the upper edge e, the lower edge f, the left edge g, and the right edge h is the area covered by the touch sensor 416 , otherwise it is the area not covered by the touch sensor 416 No coverage area. Therefore, after analyzing the positions of the endpoints of the plurality of touch sensors, the analysis module 146 can obtain the non-coverage area non_c2 on the touch panel not covered by the touch sensors by intersecting the non-coverage areas of the touch sensors.

Then, in step S270 , the extension module 148 extends the coverage area of the initial sensor pattern to the non-coverage area to generate at least one extension area, so as to obtain the final sensor pattern with at least one extension area. That is to say, the extension module 148 can change the shape of the initial sensor pattern to generate a final sensor pattern with at least one extension area, wherein the sensing area of the final sensor pattern on the touch panel is larger than the sensing area of the initial sensor pattern on the touch panel .

Specifically, in an embodiment, the extension module 148 may obtain the area range of the non-coverage area according to the information provided by the analysis module 146 . Therefore, the extension module 148 can directly change the sensor pattern of the touch sensor according to the area range of the non-coverage area, or increase the extension area on the outer edge of the initial responder pattern through further calculation to expand the sensing range. For example, the extension module 148 can calculate the distance between two adjacent touch sensors to determine the size of the extension area. In another embodiment, the extension module 148 may also calculate the area of the non-coverage area to determine the size of the extension area. In this way, adding the touch sensor behind the extended area can expand the touch range, so that more touch sensors can sense changes through the user's touch operation.

For example, FIG. 5A-FIG. 5C show an example of a style adjustment method according to an embodiment of the present invention. Please refer to FIG. 5A , in this example, the initial sensor pattern is a rectangular pattern. The extension module 148 adds line-segment-shaped extension regions 511_21 - 511_24 from the edge of the main region 511_1 of the initial sensor pattern. By analogy, the extension module 148 makes the respective extension areas of the touch sensors 511 - 514 cover the non-covered area in the same manner.

In detail, the extension module 148 can know according to the information about the non-coverage area provided by the analysis module 146 that the left edge of the touch sensor 511 is separated from the right edge of the touch sensor 513 by a distance d1. Therefore, the extension module 148 can determine the extension area length K1 of the extension areas 511_21 - 511_24 , and add the extension area 511_21 and the extension area 511_22 at the position point X and the position point Y on the left edge of the touch sensor 511 . In this example, the position point X and the position point Y are, for example, equal division points obtained by dividing the length of the edge of the sensor equally, but the present invention is not limited thereto. It should be noted that, in addition to extending the coverage of the initial sensor pattern by means of automatic calculation. In another embodiment, the extension module 148 can receive a user's operation instruction to determine the length of the extension area.

Please refer to FIG. 5B , in this example, the initial sensor pattern is a diamond pattern. The extension module 148 adds line-segment-shaped extension regions 521_21 - 521_26 from the edge of the main region 521_1 of the initial sensor pattern. Similarly, the extension module 148 can determine the size and location of the extension areas 521_21 - 521_26 according to the information about the non-coverage area provided by the analysis module 146 . By analogy, the extension module 148 makes the respective extension areas of the touch sensors 521 - 525 cover the non-covered area in the same manner. Similarly, the extension module 148 can also receive an operation command from the user to determine the lengths of the extension areas 521_21˜521_24.

In addition, please refer to FIG. 5C , in this example, the initial sensor pattern of each touch sensor 531 - 538 is a rhombus pattern. The extension module 148 enlarges the main area 531_1 corresponding to the initial sensor pattern of the touch sensor 531 according to the scaling ratio, and generates at least one extension area 531_2 , so that the extension area of each touch sensor covers the non-covered area. In detail, the extension module 148 can determine the scaling ratio according to the size of the non-coverage area, and expand the initial sensor pattern according to the scaling ratio. Likewise, in another embodiment, the extension module 148 may receive a user's operation instruction to determine the zoom ratio.

It should be noted that, compared with the extension regions shown in FIG. 5A and FIG. 5B , the extension region shown in FIG. 5C is not also in the shape of a line segment. Further, the present invention does not limit the shape of the extension area, and any extension area that can be used to extend the original sensor pattern shall fall within the scope of the present invention. Based on the above-mentioned embodiments, it can be seen that the sensing range of the final sensor pattern is enlarged after the extension area is increased, and the overlapping portion of the sensing areas of each touch sensor can also be increased. That is to say, the method of the present invention can further adjust the sensing range of the touch sensor according to the non-coverage area in the original layout state. In this way, the phenomenon of determining the position of the touch point only by the sensing value of a single sensor can be avoided, and the accuracy of touch detection can be improved.

Returning to the flow chart of FIG. 2 , after the final sensor pattern is determined, in step S290 , the time judging module 149 can judge whether the charging and discharging time associated with the final sensor pattern is greater than a threshold value. It should be noted that in this embodiment, during the process of extending the initial sensor pattern, the charging and discharging time of the sensor can also be used as one of the design factors for adjusting the final sensor pattern. The reason is that if the range of the final sensor pattern is too large, the charging and discharging time required for the sensor will be longer. Once the charging and discharging time is too long, the sensing time of the sensor will also be prolonged, which makes the user feel that the touch response is sluggish. Therefore, when the charging and discharging time is greater than the threshold value, the extension module 148 again extends the coverage of the initial sensor pattern to the non-coverage area to generate at least one new extension area, so as to obtain the final sensor pattern with the new at least one extension area.

To sum up, the present invention increases the sensing range of a single touch sensor by extending the coverage of the touch sensor, thereby increasing the overlapping portion of the sensing range of each touch sensor. Therefore, the contact position of the contact operation can be effectively positioned, thereby greatly improving the positioning accuracy. In addition, the present invention can widen the sensing range of each touch sensor and reduce the area that cannot be accurately detected without changing the number of sensing channels of the touch chip. In this way, the manufacturing cost can be saved and the accuracy of touch detection can be improved at the same time. Furthermore, since the accuracy of the touch point is increased, when the user performs a drag operation on the touch panel to generate a straight line segment, the problem of jaggedness due to inaccurate touch can be reduced.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the various embodiments of the present invention. scope.
