[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0028] It should be noted that the present application specification does not enumerate all optional implementation modes. After reading the present application specification, those skilled in the art should be able to understand that as long as the technical features do not contradict each other, any combination of the technical features can constitute an optional implementation mode.

[0029] In electronic devices based on touch screens, interaction can be performed directly based on the display screen, and the display and operation are synchronized. From the perspective of user interaction experience, a device completes the detection of touch operations and the display of corresponding screens; from the perspective of subdivided functional hardware, the detection of touch operations and the display of corresponding screens are realized through different hardware modules. Figure 2 As shown, in an electronic device 20, the touch display screen is assembled by a touch module 21 and a display screen 22 in a similar layered stacking manner, wherein the touch module 21 realizes the detection of touch operations, and the display screen 22 realizes the display of corresponding pictures, and the touch detection range of the touch module 21 coincides with or nearly coincides with the display range of the display screen 22. In this setting state, the touch module 21 and the display screen 22 can establish a mapping relationship of the coordinate system based on the physical relative position relationship, so that when the touch position parameters on the touch module 21 are used on the display screen 22 through the mapping relationship, the corresponding position is coincident or the deviation is within the design allowable range, so that the touch position parameters detected by the touch module 21 can accurately point to the user's touch operation target in the display screen 22.

[0030] In order to achieve the above interactive goals, when developing touch screens, it is necessary to test the accuracy of their touch responses, that is, to measure the positional offset between the actual physical touch point and the screen display response point. The smaller the offset distance, the higher the touch accuracy. The existing common measurement method is: calibrate multiple test sites on the screen, aim through the human eye, use a touch pen or other tool to click the center position of each test site, calculate the difference between the coordinates of the touch response when clicking and the actual coordinates of the calibrated test site, so as to obtain the touch accuracy value, and compare it with the product standard to determine whether it meets the standard. The above operation process of multiple operations of human eye aiming is complicated, the judgment of the touch response coordinates and the actual coordinates is cumbersome, and the touch offset detection result is not intuitive.

[0031] In response to the above technical problems, this solution proposes a touch offset detection tool. When performing touch offset detection using the touch offset detection tool, the inspector only needs to hold the hollow tube and stick the touch head to the electronic device. The electronic device confirms the comparison point position parameters according to the first confirmation rule based on the multiple position parameters generated by the multiple touch heads, and displays the comparison points accordingly. The inspector can quickly confirm whether the offset distance is within the design requirements by observing the comparison points in the hollow tube, thereby simplifying the test operation process and intuitively presenting the test results.

[0032] The touch offset detection tool in the embodiment of the present application can be applied to touch display screens implemented by various types of touch modules and display screen combinations, and the specific detection target is not limited by the type of touch module and / or display screen and the installation method of the two.

[0033] The following is a detailed description of the various embodiments of the present invention.

[0034] Figure 1 A touch offset detection tool 10 is provided in an embodiment of the present application. The touch offset detection tool 10 includes at least two touch heads 104, a base 102, and a cylindrical hollow tube 101. The mounting ends of the at least two touch heads 104 are connected to the first side surface of the base 102. The touch ends of the at least two touch heads 104 are both located in a first plane. The first plane has a reference point confirmed according to the position of the touch ends according to a first confirmation rule. The base 102 is provided with an observation hole 103 that passes through the second side surface and the first side surface. The first end of the hollow tube 101 is embedded in or connected to the observation hole 103 from the second side surface. The reference point is located within a visual field when observing from the second end of the hollow tube 101 through the pipe of the hollow tube 101. When the touch offset detection tool 10 is used to perform touch offset detection, the at least two touch heads 104 are in contact with a touch display screen to be tested, so that the touch display screen to be tested detects the contact positions corresponding to the at least two touch heads 104, and displays a comparison point at a comparison point position determined according to the first confirmation rule and the contact position. The comparison point confirms the offset state to the user by whether the user is within the visual field when observing through the pipe of the hollow tube 101.

[0035] In the embodiment of the present application, the first plane is a spatial concept for constraining the positional relationship of the touch ends of the touch head 104, that is, the touch ends are located in the same plane. Based on this positional relationship, all touch ends can contact a plane at the same time, thereby ensuring that touch position parameters corresponding to multiple touch points can be generated when testing the touch display screen. The touch head 104 refers to a touch object that can be detected by the touch display screen to be tested. Specifically, the type of touch object can be selected according to the type of the touch display screen to be tested. For example, a touch display screen based on a capacitive touch module or an inductive touch module requires a capacitive touch head or an inductive touch head accordingly.

[0036] The reference point refers to a point in a space concept located on the first plane within the visual range when viewed through the pipe from the second end of the hollow tube 101, and the point does not exist in real terms. The first confirmation rule is used to characterize the relative position relationship between the reference point and the touch terminal, that is, according to the position of the touch terminal, the first confirmation rule can unambiguously confirm the only reference point that satisfies the relative position relationship with the touch terminal.

[0037] On the basis of confirming the position of the touch head 104 and that the touch ends are all located in the same plane, there is no strict order relationship between the reference point on the first plane, the first confirmation rule, and the field of view of the first plane in the hollow tube 101. When implementing the touch offset detection tool 10 in the embodiment of the present application, the reference point can be first confirmed according to the distribution of the touch end according to the first confirmation rule, and then the installation position of the hollow tube 101 can be confirmed according to the reference point and the relationship between the hollow tube 101 and the reference point. It is also possible to first design the hollow tube 101 according to the convenience of use, and then confirm the field of view of the pipe in the first plane, and finally take a point from the field of view as a reference point, and then confirm the relative position relationship between the reference point and the touch end, that is, confirm the first confirmation rule. In the overall implementation process, the reference point can be controlled to be located at the center of the field of view of the pipe in the first plane.

[0038] The cylindrical hollow tube 101 is used to view the information within the field of view. If a marker is set at the reference point, the marker can be seen through the pipe of the hollow tube 101; if the reference point is located at the center of the field of view of the first plane, the marker can be seen at the center of the field of view through the pipe of the hollow tube 101. The size of the specific pipe is set according to the touch accuracy requirement. The higher the touch accuracy requirement, the smaller the pipe. The shape of the observation hole 103 is adapted to the hollow tube 101, and part of the hollow tube 101 is embedded in the observation hole, or the hollow tube 101 is connected to the observation hole 103 so that the observation hole 103 serves as an extension of the pipe. On the whole, the opening of the observation hole 103 and the matching relationship between the hollow tube 101 and the observation hole 103 do not affect the observation of the reference point through the pipe.

[0039] Based on the clear relative position relationship of each component on the touch offset detection tool, the touch offset detection tool can be used to detect the touch position parameters corresponding to the touch end on the touch module, and based on the touch position parameters, when the display screen responds, a comparison point is generated on the display screen according to the first confirmation rule. If the coordinate system of the touch module and the coordinate system of the display screen are adapted to overlap, and because the touch end can be regarded as the overlap of the first plane and the touch display screen when in contact with the touch display screen, then the comparison point should appear exactly at the position of the reference point, which is equivalent to a marker appearing at the position of the reference point. The worse the degree of adaptation between the coordinate system of the touch module and the coordinate system of the display screen, the greater the deviation between the display position of the comparison point and the reference point, that is, the greater the touch offset, so that the touch offset detection result can be directly observed through a single detection operation. When performing touch offset detection using the touch offset detection tool, the inspector only needs to hold the hollow tube and stick the touch head to the electronic device. The electronic device confirms the comparison point position parameters according to the first confirmation rule based on the multiple position parameters generated by the multiple touch heads, and displays the comparison points accordingly. The inspector can quickly confirm whether the offset distance is within the design requirements by observing the comparison points in the pipeline, thereby simplifying the test operation process and intuitively presenting the test results.

[0040] Based on the above overall design concept, the touch head 104, the base 102 and the cylindrical hollow tube 101 can have a variety of specific installation details. For example, the extension line of the hollow tube 101 can obliquely intersect the first plane, that is, the hollow tube 101 may not be perpendicular to the touch display screen during detection, as long as the first confirmation rule is accurately set and the reference point is within the field of view of the pipe.

[0041] In order to simplify production and manufacturing, be convenient and comfortable to use, or be easy to store, the implementation details of the touch offset detection tool can be further designed.

[0042] In a specific design approach, such as Figure 3 As shown, the base 102 of the touch offset detection tool 10 is a columnar base; at least two touch heads 104 are perpendicular to the first side; and the hollow tube 101 is perpendicular to the second side. Through a columnar base, such as a cylindrical base, a rectangular base, and a cube base, the hollow tube 101 and the touch head 104 can be vertically arranged on two parallel and opposite side surfaces (which may be the bottom surface according to geometric naming habits), respectively. During specific detection, the hollow tube 101 is perpendicular to the touch display screen of the electronic device 20, and the observation angle of the detection personnel is more comfortable. The columnar hollow tube 101 can be a round tube or a square tube, and the opening of the observation hole 103 can be adapted to the shape of the hollow tube 101.

[0043] To ensure that the relative position relationship between the hollow tube 101 and the touch display screen in the vertical direction is unique during detection, the number of touch heads 104 is at least three, and the three touch heads are not on the same straight line. When the unique first plane determined by the three touch heads contacts the touch display screen, the hollow tube 101 and the touch display screen have only a unique angle, such as a right angle, thereby avoiding detection deviation due to operation deviation during detection.

[0044] In order to facilitate setting the first confirmation rule during the production process, the touch ends of each touch head are located at different vertices of the regular polygon. Correspondingly, the reference point can be set to the center of the regular polygon. In terms of the overall structural unity, the shape of the first side surface is the same as or similar to the shape of the regular polygon. The calculation of confirming the reference point based on the regular polygon is relatively simple, and it is faster and more accurate when confirming the position of the observation hole.

[0045] Please refer to Figure 5 , which is a method flow chart of a touch offset detection method provided in an embodiment of the present application, and the touch offset detection method is implemented by an electronic device. Please refer to Figure 5 The touch offset detection method includes steps S110 to S140:

[0046] Step S110: Entering the touch shift detection mode, and displaying the writing detection interface in the touch shift detection mode.

[0047] The detection of touch screens is usually carried out in the research and development stage. In the research and development stage, the touch screen in the component state can be assembled and adjusted at the hardware level and parameter settings at the data level until the coordinate system of the touch module and the display is adapted. It can be delivered for production according to the final assembly plan and parameters. The touch offset detection method in the embodiment of the present application is used to detect the adaptation effect of the intermediate state of assembly adjustment and parameter setting. In the research and development stage, the touch display in the component state can be connected to the electronic device through an interface, and the electronic device executes the corresponding program to complete the touch offset detection method based on the touch offset detection tool in the previous embodiment.

[0048] The electronic device has previously been connected to the touch display screen to be tested, and has completed the settings related to the pre-adaptation of the coordinate system of the touch module and the display screen. On this basis, it can receive the touch position parameters detected by the touch module, and confirm a position on the display screen for response according to the adaptation relationship between the touch position parameters and the settings. If the adaptation effect is not finally confirmed, the touch offset detection mode can be entered, and the writing detection interface is displayed in the touch offset detection mode. The writing detection interface is a detection interaction interface developed in response to the aforementioned touch offset detection tool. The writing detection interface can receive touch operations and display writing content. Different from the writing-is-what-you-get on application software such as whiteboard applications, and the writing method in which multi-point writing produces multiple handwritings, the writing detection interface in the embodiment of the present application implements a writing method in which multi-point writing operations produce one writing handwriting.

[0049] The writing detection interface can be an application interface of a test application developed separately, or it can be a sub-interface corresponding to a sub-function integrated in a writing application (such as a whiteboard application). Accordingly, entering the touch offset detection mode can be achieved by opening a test application, or by opening a sub-function of a writing application. In the touch offset detection mode, the data processing process of the system layer remains unchanged, that is, the system layer keeps processing the touch position parameters according to the adaptation scheme, and distributes them to the application corresponding to the currently displayed writing detection interface for processing. For example, the original position (a, b) detected by the touch module is processed according to the adaptation scheme to correspond to the response position of the display screen (a`, b`). The goal of the adaptation is to make (a, b) and (a`, b`) the same position (or a highly close position) in terms of the interactive effect. The goal of the touch offset detection is to confirm how large the deviation between (a, b) and (a`, b`) is.

[0050] Step S120: Acquire a plurality of touch position parameters detected by the touch module when a multi-touch operation is performed on the writing detection interface using a touch offset detection tool.

[0051] The touch offset detection tool in the embodiment of the present application includes at least two touch heads, a base and a cylindrical hollow tube; the mounting ends of at least two touch heads are connected to the first side of the base, the touch ends of at least two touch heads are located in the first plane, and there is a reference point on the first plane that is confirmed according to the position of the touch end according to the first confirmation rule; the base is provided with an observation hole that runs through the second side and the first side, the first end of the hollow tube is embedded in or connected to the observation hole from the second side, and the reference point is located within the field of view when observing from the second end of the hollow tube through the pipe of the hollow tube. After the writing detection interface is displayed, the detection personnel hold the touch offset detection tool so that the multiple touch ends of the touch head contact the touch display screen. For the electronic device, the multi-touch operation will be detected by the touch module. Even if the initial adaptation has deviations, it can basically ensure that the multi-touch operation occurs in the writing detection interface for the display screen. Therefore, it can be directly defined here as obtaining the multi-touch operation on the writing detection interface, and correspondingly obtaining the multiple touch position parameters detected by the touch module. The detection of specific touch position parameters has been implemented in the touch field, and will not be described in detail here.

[0052] Step S130: confirming the comparison point position parameters according to the first confirmation rule based on the plurality of touch position parameters.

[0053] The touch position parameters are position parameters detected by the touch module, and the relative position relationship between each touch position parameter corresponds to the relative position relationship of the touch end on the touch offset detection tool. The comparison point position parameters are confirmed according to the first confirmation rule based on the multiple touch position parameters. First, the touch position parameters are converted into display position parameters in the coordinate system of the display screen according to the adaptation relationship between the coordinate system of the touch module and the display screen. In this process, it is an equal-proportional conversion. After the conversion, the display position parameters still have the same relative position relationship as the touch end and the touch position parameters. The touch end is confirmed to have a unique reference point according to the first confirmation rule, and the display position parameters can also confirm a unique position parameter according to the first confirmation rule, that is, the comparison point position parameter.

[0054] According to the first confirmation rule, the mathematical relationship between the display position parameters and the comparison point position parameters can be confirmed, and then the comparison point position parameters can be obtained based on the display position parameters according to the mathematical relationship. For example, the four display position parameters correspond to the four vertices of a quadrilateral, and the first confirmation rule is the intersection of the diagonals of the quadrilateral. If the four display position parameters are (x 1 ,y 1 )、(x 2 ,y 2 )、(x 3 ,y 3 ) and (x 4 ,y 4 ), calculate the coordinates of the diagonal intersection point (xc ,y c ), i.e. the center point coordinates, can be calculated as follows:

[0055]

[0056]

[0057] The above calculation method can be applied to any quadrilateral, including rectangles, parallelograms, rhombuses, etc.

[0058] Step S140: displaying the comparison points on the writing detection interface according to the comparison point position parameters.

[0059] The comparison point can be any iconic pattern display, such as a dot, a cross pattern, etc., which can be displayed at the comparison point position parameter.

[0060] In the embodiment of the present application, the electronic device is used to cooperate with the detection personnel to complete the contrast display required for the touch offset detection and judgment, and the electronic device itself may not be able to complete the judgment of the offset result. For the detection personnel, if the existence of a landmark pattern can be observed within the field of view through the pipe of the hollow tube, it can be confirmed that the touch offset is relatively small or the touch offset is acceptable; if the landmark pattern can be observed through the hollow tube to be located at the center of the field of view, it can be confirmed that the touch offset can be basically ignored; if the landmark pattern cannot be observed within the field of view through the hollow tube, it means that the touch offset has not yet met the design requirements.

[0061] The specific detection principle can be Figure 4 Make intuitive comparative analysis. Figure 4 In the figure, it is assumed that the four black dots 23 represent the four position points corresponding to the touch position parameters. According to the four touch position parameters, the position parameters of the reference point 231 can be uniquely confirmed, but the position is not actually displayed according to the position parameters of the reference point 231. According to the four touch position parameters, the four display position parameters in the display screen can also be obtained, that is, the position parameters of the positions of the four slash crosses 24, that is, the display position parameters, but these four positions are not actually displayed. According to the four display position parameters, the comparison point position parameters can be obtained, and the black cross 241 will be displayed as an indicative pattern at the comparison point position parameters. In the above position parameter change process, the relative position relationship between the reference point 231 and the four black dots 23 is the same as the relative relationship between the black cross 241 and the four slash crosses 24. If the touch module and the display screen are properly adapted, the display positions of the four black dots 23 and the four slash crosses 24 should overlap, and the black cross 241 should be seen at the reference point. If the touch module and the display screen are not properly adapted, it will appear Figure 4The effect is that the black cross 241 as a landmark pattern appears at the offset reference point 231, the offset is large, and the adaptation of the coordinate system of the touch module and the display screen has not yet met the design requirements. If the black cross 241 appears exactly at the position of the reference point 231, that is, it appears at the center of the field of view when observing through the hollow tube, it can be confirmed that the four oblique crosses 24 appear exactly at the positions of the four black origins 23, that is, the display position parameters obtained according to the touch position parameters coincide. Through the above design principles, the touch offset detection tool and touch offset detection method provided in this solution can intuitively see the touch offset detection results with only one operation.

[0062] In another optional implementation, the writing detection interface also displays a result confirmation control; accordingly, the touch offset detection method also includes: confirming and recording the detection result according to a single-point click operation acting on the result confirmation control. In an embodiment of the present application, the detection personnel can only judge whether the comparison point is within the field of view or in the general position of the field of view by naked eyes, that is, the detection personnel can basically only make qualitative judgments, not quantitative judgments. Therefore, the result confirmation control can be set according to the judgment ability of the detection personnel, such as whether it is within the field of view, or roughly judge the position in a certain direction of the field of view, whether it is in the center. By recording the test results, the assembly method and / or parameter configuration of the touch module and the display screen can be further adjusted with reference to the test results in the subsequent research and development process, or it can be confirmed that the current adaptation method has met the design requirements, and the touch position parameters can obtain highly corresponding display position parameters according to the adaptation relationship.
