[0002] The present application relates to the field of testing technology, and in particular to a testing system, electronic equipment, and control method. Background Art

[0003] With technological advancements, terminal devices using capacitive touchscreens have grown in popularity. Users often use a stylus to write on a capacitive touchscreen, enabling handwritten input on the device. Because each capacitive unit in a capacitive touchscreen responds differently to touch, writing on the device may result in discontinuous strokes, significantly impacting the user's input experience. Therefore, before leaving the factory, terminal devices using capacitive touchscreens typically undergo calibration testing of each capacitive unit.

[0004] Currently, a stylus is clamped by a clamping mechanism to draw a line on a capacitive touch screen, thereby performing a calibration test on each capacitance unit of the terminal device.

[0005] However, the test results of the test system in the prior art have low accuracy. Summary of the Invention

[0006] The embodiments of the present application provide a test system, an electronic device, and a control method, which are applied in the field of testing technology and help to improve the accuracy of test results of a calibration test of the test system.

[0007] In a first aspect, embodiments of the present application provide a test system comprising: a first device, a second device, and a third device, wherein the third device comprises a capacitive touch screen to be tested, and the capacitive touch screen to be tested comprises a plurality of capacitor units.

[0008] When the first device acts on the capacitor unit of the capacitive touch screen to be tested, the capacitor unit generates an induction signal; the second device includes a clamping module, a first transmission module, a second transmission module and a pressure detection module; the clamping module is used to clamp the first device, the first transmission module is used to drive the clamping module to move along a target direction, the target direction includes a direction away from or close to the capacitive touch screen to be tested, the second transmission module is used to drive the clamping module to move along a preset track on the capacitive touch screen to be tested, and the pressure detection module is used to detect the pressure applied by the first device to the capacitive touch screen to be tested.

[0009] The second device is used to obtain the pressure applied by the first device to the capacitive touch screen to be tested through the pressure detection module when the clamping module clamps the first device and moves it along a preset trajectory on the capacitive touch screen to be tested, and when the pressure applied by the first device to the capacitive touch screen to be tested exceeds a preset pressure range, drive the clamping module to move through the first transmission module so that the pressure applied by the first device to the capacitive touch screen to be tested after movement is within the preset pressure range.

[0010] In this way, the test system detects and adjusts the pressure applied by the first device to the capacitive touch screen under test during testing, helping to reduce the probability that the pressure applied by the first device to the capacitive touch screen under test exceeds a preset pressure range. This helps improve the accuracy of the calibration signal used to determine whether each capacitive unit has been touched, thereby improving the accuracy of the calibration test results.

[0011] In one possible implementation, the second device also includes a limiting mechanism, and the pressure detection module is arranged between the limiting structure and the clamping module. The limiting mechanism is used to limit the movement of the pressure detection module; the pressure detection module is used to detect the reaction force of the first device when the clamping module clamps the first device and applies pressure to the capacitive touch screen to be tested.

[0012] In this way, securing the pressure detection module with the limiting mechanism facilitates the dynamic sensing of the pressure applied by the first device to the capacitive touch screen under test by the pressure detection module, thereby facilitating the sensing and adjustment of the pressure applied by the first device 901 to the capacitive touch screen under test by the test system.

[0013] In one possible implementation, the second device is specifically used to: when the pressure applied by the first device to the capacitive touch screen to be tested is greater than the maximum value in a preset pressure range, drive the clamping module away from the capacitive touch screen to be tested through the first transmission module; and / or when the pressure applied by the first device to the capacitive touch screen to be tested is less than the minimum value in the preset pressure range, drive the clamping module close to the capacitive touch screen to be tested through the first transmission module.

[0014] In this way, the first transmission module can be used to move the clamping module away from or closer to the capacitive touch screen under test, helping to reduce the probability that the pressure applied by the first device to the capacitive touch screen under test exceeds a preset pressure range. This helps improve the accuracy of the calibration signal used to determine whether each capacitive unit has been touched, and helps improve the accuracy of the calibration test results.

[0015] In one possible implementation, the second device includes a control module, which is used to control the second transmission module to drive the clamping module to move along a preset trajectory; the control module is also used to obtain the pressure applied by the first device to the capacitive touch screen to be tested from the pressure detection module when the first device is at the pressure sampling point, and when the pressure applied by the first device to the capacitive touch screen to be tested exceeds a preset pressure range, control the first transmission module to drive the clamping module away from or close to the capacitive touch screen to be tested; the preset trajectory includes at least one pressure sampling point.

[0016] In this way, the control module helps to control the movement of the first device and helps to control the movement of the clamping module along a preset trajectory or the adjustment process of the pressure applied by the first device to the capacitive touch screen to be tested.

[0017] In one possible implementation, the testing system also includes: a fourth device, used to control the second transmission module to drive the clamping module to move along a preset trajectory; the fourth device is also used to obtain the pressure applied by the first device to the capacitive touch screen to be tested from the pressure detection module when the first device is at the pressure sampling point, and when the pressure applied by the first device to the capacitive touch screen to be tested exceeds a preset pressure range, control the first transmission module to drive the clamping module away from or close to the capacitive touch screen to be tested; the preset trajectory includes at least one pressure sampling point.

[0018] In this way, the fourth device helps to control the movement of the first device and helps to control the movement of the clamping module along a preset trajectory or the adjustment process of the pressure applied by the first device to the capacitive touch screen to be tested.

[0019] In one possible implementation, the test system is further used to generate an alarm message when the pressure applied by the first device to the capacitive touch screen to be tested is greater than a first preset threshold or less than a second preset threshold; wherein the first preset threshold is greater than the maximum value in the preset pressure range, and the second preset threshold is less than the minimum value in the preset pressure range.

[0020] In this way, the test system can issue an alarm when the pressure applied by the first device to the capacitive touch screen to be tested is greater than the first preset threshold or less than the second preset threshold, which helps to improve the intelligence level of the test system.

[0021] In one possible implementation, the third device is configured to record a capacitance signal of each capacitor unit in response to movement of the first device on the capacitive touch screen to be tested;

[0022] The third device is further configured to obtain a difference signal of each capacitor unit according to a difference between the capacitance signal and the preset signal.

[0023] In this way, the test system obtains the calibration signal of the capacitance signal of each capacitor unit through the difference signal, thereby helping to improve the accuracy of the calibration signal when used to determine whether each capacitor unit has been touched, and helping to improve the accuracy of the test results of the calibration test.

[0024] In one possible implementation, the first transmission module includes a first drive motor and a first transmission mechanism, and the second transmission module includes a second drive motor and a second transmission mechanism. The first drive motor is used to drive the first transmission mechanism to transmit in a target direction so that the clamping module moves away from or close to the capacitive touch screen to be tested; the second drive motor is used to drive the second transmission mechanism to transmit so that the clamping module clamps the first device and moves along a preset trajectory on the capacitive touch screen to be tested.

[0025] In this way, it is helpful to realize the movement of the first device, and to realize the movement of the clamping module along a preset track or to adjust the pressure applied by the first device to the capacitive touch screen to be tested.

[0028] The pressure detection module is used to detect the pressure applied by the first device to the capacitive touch screen to be tested; the electronic device is used to obtain the pressure applied by the first device to the capacitive touch screen to be tested through the pressure detection module when the clamping module clamps the first device and moves it along a preset trajectory on the capacitive touch screen to be tested, and when the pressure applied by the first device to the capacitive touch screen to be tested exceeds a preset pressure range, drive the clamping module to move through the first transmission module so that the pressure applied by the first device to the capacitive touch screen to be tested after movement is within the preset pressure range.

[0052] In order to clearly describe the technical solutions of the embodiments of the present application, some of the terms and technologies involved in the embodiments of the present application are briefly introduced below.

[0053] In the embodiments of this application, terms such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. For example, the terms "first chip" and "second chip" are used solely to distinguish between different chips and do not define their order. Those skilled in the art will understand that terms such as "first" and "second" do not define the quantity or execution order, and do not necessarily define differences.

[0054] It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0055] In the embodiments of the present application, the terminal device may be a handheld device or vehicle-mounted device with a capacitive touch screen. For example, some terminal devices include mobile phones, tablet computers, PDAs, laptop computers, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, and augmented reality (AR) devices, but the embodiments of the present application do not limit this.

[0056] Users can easily perform handwriting input with a stylus, especially in scenarios such as taking notes, drawing, and making drawings. The stylus can provide users with a good input experience. Whether a terminal device using a capacitive touch screen supports stylus input and whether the handwriting input function is normal has a significant impact on the user's input experience. However, due to reasons such as the production process of the capacitive touch screen, the various capacitor units in the capacitive touch screen have different touch sensitivity. For example, some capacitor units are more sensitive to touch, while some capacitor units are not. This will be reflected as discontinuous strokes when the user writes on the capacitive touch screen. Therefore, terminal devices using capacitive touch screens usually undergo calibration tests on the various capacitor units of the terminal device before leaving the factory.

[0057] Figure 1 FIG. 1 is a schematic diagram of the structure of a test system in a related technology. Figure 1 As shown, the test system 100 drives the stylus 102 to draw a line on the capacitive touch screen 103 through the clamping mechanism 101 , and performs a capacitance unit calibration test on the terminal device 104 using the capacitive touch screen 103 .

[0058] As will be understood, capacitive touch screen 103 includes multiple capacitor units. When stylus 102 draws a line on each capacitor unit of capacitive touch screen 103, the x-axis electrodes of each capacitor unit generate an AC signal, which is sensed by the y-axis electrodes of each capacitor unit. When the AC signal passes through each capacitor unit, each capacitor unit is charged, and the test signal of the capacitance value signal of each capacitor unit changes.

[0059] It should be noted that the terminal device 104 may be configured with a preset signal value for the capacitance signal of each capacitor unit. The preset signal value may be the expected signal value for the capacitance signal of each capacitor unit when the stylus 102 draws a line on each capacitor unit of the capacitive touch screen 103 with a preset pressure. The magnitude of the preset signal value is related to the preset pressure applied by the stylus 102 when drawing a line on each capacitor unit of the capacitive touch screen 103.

[0060] In some embodiments, the preset signal value is also referred to as the standard signal value, and the preset pressure is also referred to as the standard pressure. The preset signal value for each capacitive unit of a capacitive touch screen at the same preset pressure can be the same. Different capacitive touch screens may have different preset signal values at the same preset pressure. The preset signal value can be provided by the capacitive touch screen manufacturer or can be an empirical value obtained through multiple capacitive unit calibration tests.

[0061] During the test, the terminal device 104 can record the test signal amount of the capacitance signal of each capacitor unit when it is touched by the stylus 102. The terminal device 104 can then obtain the difference between the test signal amount of the capacitance signal of each capacitor unit and the preset signal amount of the capacitor unit. This difference can be called a difference signal amount or an offset signal amount.

[0062] It is understandable that the differential signal magnitudes of each capacitor unit in a capacitive touch screen are typically inconsistent. This is because the device performance or manufacturing process of each capacitor unit varies, resulting in different test signal magnitudes of the capacitance signal detected when each capacitor unit is touched. The preset signal magnitudes of the capacitance signal of each capacitor unit in a capacitive touch screen are typically the same, resulting in different differences between the test signal magnitude and the preset signal magnitude of the capacitance signal of each capacitor unit.

[0063] In subsequent use, the terminal device 104 can calibrate the measurement signal quantity of the capacitance signal of each capacitor unit through the difference signal quantity of each capacitor unit. For example, in subsequent use of the terminal device 104, if the measurement signal quantity of the capacitance signal of a certain capacitor unit is detected, the difference signal quantity of the capacitor unit can be subtracted from the detected measurement signal quantity of the capacitance signal of the capacitor unit to obtain the calibration signal quantity of the capacitance signal of the calibrated capacitor unit, and the calibration signal quantity of the capacitance signal of the capacitor unit can be used to determine whether the capacitor unit is touched, etc.

[0064] but, Figure 1 During testing of the test system 100, the distance between the stylus 102 and the capacitive touch screen 103 may be inconsistent due to factors such as uneven placement of the capacitive touch screen 103 or tooling errors in the stylus 102, resulting in different amounts of pressure applied by the stylus 102 to the capacitive touch screen 103. In the case where the pressure applied by the stylus 102 to the capacitive touch screen 103 is different, the amount of pressure applied by the stylus 102 to the capacitive touch screen 103 may be inconsistent with the preset pressure, and the difference signal amount obtained by the preset signal amount cannot truly reflect the different touch sensing conditions of each capacitor unit. Furthermore, the calibration signal amount obtained after calibrating each capacitor unit using the difference signal may not be accurate when used to determine whether each capacitor unit has been touched, and the test results of the calibration test of the test system 100 are low in accuracy.

[0065] For example, Figure 2 This is a schematic diagram of different distances between the stylus and the capacitor unit provided in one embodiment of the present application. Figure 2 As shown, from left to right, the stylus 102 approaches the capacitor unit 201 of the capacitive touch screen 103, the stylus 102 touches the capacitor unit 201 but does not apply pressure, and the stylus 102 touches the capacitor unit 201 and applies pressure.

[0066] In some test data, when the stylus 102 is close to the capacitor unit 201 of the capacitive touch screen 103 but does not touch it, the test signal value of the capacitance signal of the capacitor unit 201 is 6500. When the stylus 102 is in contact with the capacitor unit 201 of the capacitive touch screen 103 but does not apply pressure, the test signal value of the capacitance signal of the capacitor unit 201 is 6800. When the stylus 102 is in contact with the capacitor unit 201 of the capacitive touch screen 103 and applies pressure, the test signal value of the capacitance signal of the capacitor unit 201 is 7400.

[0067] It can be seen that when the stylus 102 is in contact with the capacitor unit 201 of the capacitive touch screen 103, the test signal amount of the capacitance signal of the capacitor unit 201 is greater than the test signal amount of the capacitance signal of the capacitor unit 201 when the stylus 102 is not in contact with the capacitor unit 201 of the capacitive touch screen 103. When the stylus 102 is in contact with the capacitor unit 201 of the capacitive touch screen 103, the test signal amount of the capacitance signal of the capacitor unit 201 when the stylus 102 applies pressure to the capacitive touch screen 103 is greater than the test signal amount of the capacitance signal of the capacitor unit 201 when the stylus 102 is not applying pressure to the capacitor unit 201 of the capacitive touch screen 103.

[0068] It is understandable that when the stylus 102 contacts the capacitor unit 201 of the capacitive touch screen 103 and applies pressure, the capacitive touch screen 103 deforms slightly, and thus the distance between the stylus 102 and the capacitor unit 201 is smaller than the distance when the stylus 102 does not apply pressure to the capacitive touch screen 103.

[0069] That is, when the distance between the stylus 102 and the capacitor unit 201 varies, the pressure applied by the stylus 102 to the capacitor unit 201 varies, and the test signal amount of the capacitance signal of the capacitor unit 201 varies. Therefore, the preset signal amount is the expected signal amount of the capacitance signal of each capacitor unit when the stylus 102 applies a preset pressure to the capacitive touch screen 103, and the calibration signal amount is the calibration signal amount when the stylus 102 applies a preset pressure to the capacitive touch screen 103. Thus, if the pressure applied by the stylus 102 to the capacitive touch screen 103 is inconsistent with the preset pressure, even if the test system 100 uses the calibration signal amount to calibrate the capacitor unit, the user may still experience discontinuous handwriting when writing on the capacitive touch screen with the same pressure, affecting the user experience.

[0070] It is understandable that when the multiple capacitor units of the capacitive touch screen 103 have different touch sensing conditions, when the same pressure is applied to the multiple capacitor units of the capacitive touch screen 103 by the stylus 102, the test signal quantities of the capacitance signals of the multiple capacitor units will be different.

[0071] For example, Figure 3 This is a schematic diagram of a stylus pen applying equal pressure to multiple capacitor units of a capacitive touch screen according to an embodiment of the present application. Figure 3 As shown, the capacitive touch screen 103 includes a first capacitor unit 301, a second capacitor unit 302 and a third capacitor unit 303. The stylus 102 is used to draw a line on the first capacitor unit 301, the second capacitor unit 302 and the third capacitor unit 303 of the capacitive touch screen 103 with the same pressure.

[0072] In some test data, when the stylus 102 applies 0.1 kgf / cm2 to the first capacitor unit 301, the second capacitor unit 302 and the third capacitor unit 303 respectively, 2 ), the test signal amounts of the capacitance signals of the first capacitor unit 301, the second capacitor unit 302 and the third capacitor unit 303 are 6500, 7700 and 5500 respectively.

[0073] It can be seen that when the same pressure is applied to the first capacitor unit 301, the second capacitor unit 302 and the third capacitor unit 303 through the stylus 102, due to the different touch sensing conditions of the first capacitor unit 301, the second capacitor unit 302 and the third capacitor unit 303, the test signal amounts of the capacitance signals of the first capacitor unit 301, the second capacitor unit 302 and the third capacitor unit 303 are different.

[0074] In summary, the above-mentioned test system 100 has the following disadvantages:

[0075] During the test, the pressure applied by the stylus 102 to the capacitive touch screen 103 may be inconsistent due to factors such as the uneven placement of the capacitive touch screen 103 or tooling errors in the stylus 102. As a result, the pressure applied by the stylus 102 to the capacitive touch screen 103 may be inconsistent with the preset pressure. The difference signal quantity obtained by combining the preset signal quantity and the test signal quantity of the capacitance signal of the capacitor unit recorded by the terminal device 104 cannot truly reflect the difference in the touch sensitivity of each capacitor unit. Furthermore, the calibration signal quantity obtained after calibrating each capacitor unit using the difference signal is not necessarily accurate when used to determine whether each capacitor unit has been touched. Therefore, the test results of the calibration test of the test system 100 have low accuracy.

[0076] In light of this, embodiments of the present application provide a test system, electronic device, and control method. By providing a pressure sensor in the test system to detect and adjust the pressure applied by a stylus pen on a capacitive touch screen, the pressure applied by the stylus pen on the capacitive touch screen can be reduced, thereby reducing the deviation between the pressure applied by the stylus pen on the capacitive touch screen and a preset pressure. This helps improve the accuracy of the calibration signal used to determine whether each capacitive unit has been touched, thereby improving the accuracy of the calibration test results.

[0077] The test system of the present application is further described below with reference to the accompanying drawings and embodiments.

[0078] Figure 4 This is a schematic diagram of the structure of a test system provided in one embodiment of the present application. Figure 4 As shown, the test system 400 includes a stylus 401, a motion platform 402, and a terminal device 403. The terminal device 403 includes a capacitive touch screen 404. The motion platform 402 includes a clamping mechanism 405, a motion device 406, and a pressure sensor 407. The clamping mechanism 405 is used to clamp the stylus 401.

[0079] When testing the test system 400, the motion device 406 drives the clamping mechanism 405 to move the stylus 401 along a preset trajectory on the capacitive touch screen 404, thereby performing a capacitance unit calibration test on the terminal device 403 using the capacitive touch screen 404. The pressure sensor 407 is used to collect the pressure applied by the stylus 401 on the capacitive touch screen 404. When the stylus 401 moves to a pressure sampling point on the preset trajectory, the test system 400 obtains the pressure applied by the stylus 401 on the capacitive touch screen 404 from the pressure sensor 407.

[0080] Furthermore, when the absolute value of the difference between the pressure applied by the stylus 401 on the capacitive touch screen 404 and the preset pressure does not exceed a certain threshold, the motion device 406 drives the clamping mechanism 405 to continue moving along the preset trajectory, and the stylus 401 continues to move along the preset trajectory to draw a line on the capacitive touch screen 404. When the absolute value of the difference between the pressure applied by the stylus 401 on the capacitive touch screen 404 and the preset pressure exceeds the certain threshold, the motion device 406 drives the clamping mechanism 405 to move away from or closer to the capacitive touch screen 404, and the stylus 401 moves away from or closer to the capacitive touch screen 404. This embodiment of the application does not further limit the value of this certain threshold.

[0081] It can be understood that as the stylus 401 moves away from or closer to the capacitive touch screen 404, the pressure applied by the stylus 401 to the capacitive touch screen 404 increases or decreases, until the absolute value of the difference between the pressure applied by the stylus 401 to the capacitive touch screen 404 and the preset pressure collected by the pressure sensor 407 does not exceed the certain threshold.

[0082] For example, Figure 5 This is a schematic diagram of a capacitor unit of a capacitive touch screen provided by one embodiment of the present application. Figure 5 As shown, the capacitive touch screen 404 includes a plurality of capacitor units 501 .

[0083] It is understood that the preset trajectory includes at least one pressure sampling point. The terminal device 403 may be provided with a preset signal amount of the capacitance signal of each capacitor unit 501. During testing, the terminal device 403 may record the test signal amount of the capacitance signal of each capacitor unit 501 when the stylus 401 touches it.

[0084] In subsequent use, the terminal device 403 can obtain a difference signal by measuring the difference between the test signal amount of the capacitance signal of each capacitor unit and the preset signal amount. In subsequent use, the terminal device 403 can obtain a calibration signal amount of the capacitance signal of each capacitor unit 501 by measuring the difference between the measured signal amount and the difference signal amount, and use the calibration signal amount of the capacitance signal of each capacitor unit 501 to determine whether each capacitor unit 501 has been touched.

[0085] In this way, during testing, the testing system 400 obtains the pressure applied by the stylus 401 to the capacitive touch screen 404 from the pressure sensor 407 and adjusts the pressure applied by the stylus 401 on the capacitive touch screen 404 via the motion platform 402 to a value where the absolute value of the difference between the pressure applied by the stylus 401 on the capacitive touch screen 404 and the preset pressure does not exceed a certain threshold. This helps reduce the deviation between the pressure applied by the stylus 401 on the capacitive touch screen 404 and the preset pressure. This helps improve the accuracy of the calibration signal used to determine whether each capacitive unit has been touched, thereby improving the accuracy of the calibration test results.

[0086] In this embodiment of the present application, the shape, structure, and clamping method of the clamping mechanism 405 are not limited. The clamping mechanism 405 can be a side-locking clamping mechanism, a chuck-type clamping mechanism, a spring clamp-type clamping mechanism, or a hydraulic clamping mechanism. In this embodiment of the present application, the shape and structure of the motion platform 402 are not limited, as long as the clamping mechanism 405 can drive the stylus 401 to draw lines on the capacitive touch screen 404 and move it away from or toward the capacitive touch screen 404.

[0087] In one possible implementation, the conductive layer of the capacitive touch screen 404 provided in the embodiment of the present application is provided with M rows of x-axis electrodes and N columns of y-axis electrodes. The x-axis electrodes and the y-axis electrodes form capacitors at their intersections, constituting M*N capacitor units 501 of the capacitive touch screen 404.

[0088] In the embodiment of the present application, the preset track is set according to the arrangement of the capacitor units 501 of the capacitive touch screen 404. The embodiment of the present application does not limit the shape of the preset track.

[0089] In a possible implementation, the pressure sampling point may include a starting point of a preset trajectory.

[0090] It is understandable that when the pressure sampling point does not include the starting point of the preset trajectory, when the stylus 401 is between the starting point of the preset trajectory and the first sampling point, the test system 400 cannot obtain and adjust the pressure applied by the stylus 401 to the capacitive touch screen 404 from the pressure sensor 407, thereby increasing the probability that the absolute value of the difference between the pressure applied by the stylus 401 to the capacitive touch screen 404 and the preset pressure exceeds a certain threshold.

[0091] In this way, when the stylus 401 moves to the starting point of the preset trajectory, the pressure applied by the stylus 401 to the capacitive touch screen 404 is obtained from the pressure sensor 407. The pressure applied by the stylus 401 to the capacitive touch screen 404 is then adjusted, thereby reducing the probability that the absolute value of the difference between the pressure applied by the stylus 401 to the capacitive touch screen 404 and the preset pressure exceeds a certain threshold, which is conducive to improving the accuracy of the test results of the calibration test.

[0092] In a possible implementation, the pressure sampling point may not include the end point of the preset trajectory.

[0093] It is understandable that when the stylus 401 reaches the end point of the preset trajectory, the stylus 401 no longer draws a line, and the test system 400 does not need to obtain and adjust the pressure applied by the stylus 401 to the capacitive touch screen 404 from the pressure sensor 407. This helps reduce test time and improve test efficiency.

[0094] In a possible implementation, the preset trajectory may include multiple pressure sampling points.

[0095] It is understood that the distance between two adjacent pressure sampling points can be the product of the speed at which the motion device 406 moves along the preset trajectory and the sampling interval of the pressure sampling points. The sampling interval of the pressure sampling points can refer to the time interval between when the testing system 400 obtains from the pressure sensor 407 the pressure applied by the stylus 401 to the capacitive touch screen 404. When the speed at which the motion device 406 moves along the preset trajectory remains constant, the distance between the pressure sampling points can be proportional to the sampling interval.

[0096] In a possible implementation, the distance between the pressure sampling points may be a pressure sampling step length.

[0097] For example, Figure 6aThis is a schematic diagram of pressure sampling points provided by one embodiment of the present application. Figure 6a As shown, the pressure sampling points may include a starting point 601 of the preset track and a pressure sampling point 602. The distance between the starting point 601 of the preset track and the pressure sampling point 602 may be a pressure sampling step 603.

[0098] It is understood that the movement speed of the motion device 406 along the preset trajectory and the sampling time interval can be set according to the efficiency and accuracy requirements of the calibration test. For example, when the efficiency requirement of the calibration test is high and the accuracy requirement is low, the movement speed of the motion device 406 can be set to 1.5 mm / s and the sampling time interval can be 5 seconds. For example, when the efficiency requirement of the calibration test is low and the accuracy requirement is high, the movement speed of the motion device 406 can be set to 0.5 mm / s and the sampling time interval can be 2 seconds.

[0099] For example, Figure 6b This is a schematic diagram of pressure sampling points provided by another embodiment of the present application. Figure 6b As shown, when the capacitive touch screen 404 includes a plurality of capacitor units 501 , the preset track 604 passes through each capacitor unit 501 of the capacitive touch screen 404 , and the preset track 604 includes a plurality of pressure sampling points 605 .

[0100] It is understandable that the number of the pressure sampling points 605 may be the same as the number of the capacitor units 501 and they may correspond one to one. Figure 6b Taking setting one pressure sampling point 605 for each capacitor unit 501 as an example, a possible implementation is illustrated.

[0101] In this way, the pressure sampling point 605 can correspond to each capacitor unit 501. During the test, the absolute value of the difference between the pressure applied by the stylus 401 to each capacitor unit 501 and the preset pressure does not exceed a certain threshold, which is conducive to improving the accuracy of the test results of the calibration test of the test system 400.

[0102] For example, Figure 6c This is a schematic diagram of pressure sampling points provided in another embodiment of the present application. Figure 6c As shown, when the capacitive touch screen 404 includes a plurality of capacitor units 501 , the preset track 606 passes through each capacitor unit 501 of the capacitive touch screen 404 , and the preset track 606 includes a plurality of pressure sampling points 607 .

[0103] It is understandable that when the calibration test requires high efficiency and low accuracy, the number of pressure sampling points 607 can be less than the number of capacitor units 501. For example, a pressure sampling point 607 can be set for every capacitor unit 501, or a pressure sampling point 607 can be set for every multiple capacitor units 501. The embodiment of the present application does not further limit the number and position of the pressure sampling points 607. Figure 6c A possible implementation is illustrated by taking the example of setting a pressure sampling point 607 every two capacitor units 501 .

[0104] In this way, when the number of pressure sampling points 607 is less than the number of capacitor units 501, the number of times during the test to determine whether the pressure applied by the stylus 401 to the capacitor unit 501 exceeds a certain threshold is reduced, thereby potentially reducing the number of times the pressure is adjusted. This helps shorten the test time and improve the test efficiency of the test system 400.

[0105] For example, Figure 7 This is a schematic diagram of a pressure adjustment strategy for a test system provided in one embodiment of the present application. Figure 7 As shown, when the preset pressure is P, the pressure adjustment strategy of the test system 400 may include not adjusting the pressure applied by the stylus 401 on the capacitive touch screen 404 when the absolute value of the difference between the pressure applied by the stylus 401 on the capacitive touch screen 404 and P does not exceed A. The pressure adjustment strategy of the test system 400 may include adjusting the pressure applied by the stylus 401 on the capacitive touch screen 404 when the absolute value of the difference between the pressure applied by the stylus 401 on the capacitive touch screen 404 and P exceeds A but does not exceed B. The pressure adjustment strategy of the test system 400 may also include issuing an alarm message when the absolute value of the difference between the pressure applied by the stylus 401 on the capacitive touch screen 404 and P exceeds B.

[0106] It can be understood that the absolute value of the difference from P does not exceed A refers to [PA, P+A]. The absolute value of the difference from P exceeds A and does not exceed B refers to [PB, PA] ∪ [P+A, P+B].

[0107] It is understandable that when the absolute value of the difference between the pressure applied by the stylus 401 on the capacitive touch screen 404 and the preset pressure exceeds B, the stylus 401 may stop drawing the line.

[0108] In this way, the test system 400 detects and adjusts the pressure applied by the stylus 401 to the capacitive touch screen 404 , which is beneficial to improving the intelligence level of the calibration test and the accuracy of the test results.

[0109] In one possible implementation, the motion device 406 includes a drive module and a movement module. The drive module can be a servo motor or a stepper motor. The drive module can be driven mechanically, hydraulically, or electrically. The movement module can be any one of a linear movement module, a rotational movement module, a multi-degree-of-freedom movement module, or a parallel movement module, or can be composed of a combination of multiple movement modules. Commonly used linear movement modules include three-axis movement modules, and a motion device equipped with a three-axis movement module is a three-axis motion device. For example, Figure 4 A possible implementation of the motion device 406 is shown by taking a three-axis motion device as an example.

[0110] It is understood that the three-axis motion device drives the clamping mechanism 405 to move along the x, y, and / or z axes, thereby moving the stylus 401 away from or toward the capacitive touch screen or moving along a predetermined trajectory to draw a line on the capacitive touch screen 404. This embodiment of the application does not limit the shape and structure of the motion device 406; as long as it can drive the clamping mechanism 405 to move, thereby driving the stylus 401 to draw a line on the capacitive touch screen 404 and moving the stylus 401 away from or toward the capacitive touch screen 404, it will suffice.

[0111] In one possible implementation, motion platform 402 further includes a limiting mechanism, and pressure sensor 407 is disposed between the limiting mechanism and clamping mechanism 405. The limiting mechanism limits the movement of pressure sensor 407. When clamping mechanism 405 clamps stylus 401 and applies pressure to capacitive touch screen 404, pressure sensor 407 detects the pressure applied by stylus 401 to capacitive touch screen 404 through the reaction force exerted by capacitive touch screen 404 on stylus 401.

[0112] In the embodiment of the present application, the shape and structure of the limiting mechanism are not limited; it can be a limiting protrusion, a limiting column, or a limiting groove, as long as it can limit the movement of pressure sensor 407. Pressure sensor 407 converts the pressure applied by stylus 401 to capacitive touch screen 404 into a pressure signal. Testing system 400 receives the pressure signal from pressure sensor 407 and uses it to determine whether the absolute value of the difference between the pressure applied by stylus 401 on capacitive touch screen 404 and a preset pressure exceeds a certain threshold.

[0113] In this way, the pressure sensor 407 can be fixed by the limiting mechanism, and the pressure sensor 407 can detect the pressure applied by the stylus 401 to the capacitive touch screen 404. This helps the test system 400 sense the pressure applied by the stylus 401 to the capacitive touch screen 404.

[0114] In a possible implementation, when the absolute value of the difference between the pressure applied by the stylus 401 to the capacitive touch screen 404 and a preset pressure exceeds a certain threshold, an alarm message is generated.

[0115] In this way, the test system 400 can issue an alarm when the absolute value of the difference between the pressure applied by the stylus 401 to the capacitive touch screen 404 and the preset pressure exceeds a certain threshold, which helps to improve the intelligence level of the test system 400.

[0116] In one possible implementation, when the absolute value of the difference between the pressure applied by the stylus 401 to the capacitive touch screen 404 and the preset pressure exceeds a certain threshold, the motion device 406 and the clamping mechanism 405 stop moving, and the stylus 401 stops drawing.

[0117] This reduces the probability of the test system 400 performing a calibration test under abnormal pressure, thereby helping to improve the accuracy of the test results of the test system 400. It also reduces the probability of the stylus 401 scratching the capacitive touch screen 404 when applying excessive pressure, thereby helping to extend the service life of the capacitive touch screen 404.

[0118] In one possible implementation, when the number of times the pressure applied by the stylus 401 to the capacitive touch screen 404 is adjusted by the stylus 401 moving away from or approaching the capacitive touch screen 404 exceeds a certain threshold, the motion device 406 and the clamping mechanism 405 stop moving, and the stylus 401 stops drawing.

[0119] In the embodiment of the present application, the threshold value is an upper limit on the number of pressure adjustments. If the clamping mechanism 405 moves the stylus 401 away from or toward the capacitive touch screen 404 more times than the threshold value and still fails to adjust the pressure applied by the stylus 401 to the capacitive touch screen 404 to a value where the absolute difference from the preset pressure does not exceed another threshold value, this may be due to excessive pulse equivalent of the motion device 406 or a malfunction of the test system 400.

[0120] It will be appreciated that when the motion module of motion device 406 is a linear motion module, the pulse equivalent refers to the distance moved by clamping mechanism 405. When the motion module of motion device 406 is a rotary motion module, the pulse equivalent refers to the angle rotated by clamping mechanism 405. When the driving module of motion device 406 is a stepper motor, the magnitude of the pulse equivalent is proportional to the step length of the stepper motor.

[0121] It is understandable that when the pulse equivalent of the motion device 406 is too large, the distance moved or the angle rotated by the clamping mechanism 405 is too large, resulting in the pressure applied by the stylus 401 to the capacitive touch screen 404 being unable to be adjusted to a value where the absolute value of the difference from the preset pressure does not exceed another certain threshold.

[0122] In this way, when the number of times that the test system 400 adjusts the clamping mechanism to move the stylus 401 away from or closer to the capacitive touch screen 404 exceeds a certain threshold, the stylus 401 stops drawing a line, thereby reducing the probability of the test system 400 making invalid adjustments when the pulse equivalent is too large or the test system 400 malfunctions.

[0123] In one possible implementation, the movement module of motion device 406 includes a first movement module and a second movement module, and the drive module of motion device 406 includes a first drive motor for driving the first movement module and a second drive motor for driving the second movement module. The first movement module is used to drive the clamping mechanism 405 to move away from or toward the capacitive touch screen 404, and the second movement module is used to drive the clamping mechanism 405 to move along a predetermined trajectory.

[0124] In this way, it is helpful to realize the movement of the stylus 401 of the testing system 400 , and to realize the movement of the clamping mechanism 405 along a preset track or to adjust the pressure applied by the stylus 401 to the capacitive touch screen 404 .

[0125] In a possible implementation, the first moving module and the second moving module are linear moving modules, the first moving module is a z-axis moving module, and the second moving module is an xy plane moving module. The first drive motor and the second drive motor are stepping motors.

[0126] This helps to move the stylus 401 of the testing system 400 along the z-axis or in the xy plane, and helps to move the clamping mechanism 405 along a preset track or adjust the pressure applied by the stylus 401 to the capacitive touch screen 404 .

[0127] For example, Figure 8 This is a schematic diagram of the structure of a stylus pen according to an embodiment of the present application. Figure 8 As shown, the stylus 401 includes a coding electrode 801 .

[0128] In the embodiment of the present application, the stylus 401 is an active capacitive stylus, and the coding electrode 801 of the stylus 401 is used to transmit a coding signal. The coding signal may include information such as the pressure sensed by the stylus 401 tip, key status, and the stylus serial number.

[0129] In this way, the testing system 400 can use the pressure sensed by the pen tip in the coding signal to correct the pressure applied by the stylus 401 to the capacitive touch screen 404, helping to reduce the deviation between the pressure applied by the stylus 401 to the capacitive touch screen 404 and the preset pressure. This helps to improve the accuracy of the test results of the calibration test.

[0130] For example, after a capacitive touch screen is calibrated using the test system 100 in the related art, the standard deviation of the test signal quantities of the capacitance signals of the multiple capacitor units of the capacitive touch screen is 4N. After a capacitive touch screen is calibrated using the test system 400 provided in an embodiment of the present application, the standard deviation of the test signal quantities of the capacitance signals of the multiple capacitor units of the capacitive touch screen is N, where N is a positive integer.

[0131] Figure 9 This is a schematic diagram of the structure of a test system provided in another embodiment of the present application. Figure 9 As shown, a test system 900 provided by another embodiment of the present application includes: a first device 901, a second device 902 and a third device 903, and the third device 903 includes a capacitive touch screen 904 to be tested.

[0132] It is understandable that the first device 901 in the embodiment of the present application can be Figure 4 and Figure 8 Corresponding to the stylus 401 in FIG. , the second device 902 can be connected to Figure 4 Corresponding to the motion platform 402 in the figure, the third device 903 can be connected to Figure 4 Corresponding to the terminal device 403 in the embodiment, the capacitive touch screen 904 to be tested can be Figures 4 to 7 The capacitive touch screen 404 in the embodiment corresponds to the embodiment, and the beneficial effects achieved by various aspects and corresponding feasible implementation methods are similar and will not be described in detail.

[0133] The second device 902 includes a clamping module 906 , a first transmission module 907 , a second transmission module 908 and a pressure detection module 909 .

[0134] It is understood that the clamping module 906 can be used with Figure 4 The clamping mechanism 405 corresponds to the above, Figure 4 The motion device 406 may include a first transmission module 907 and a second transmission module 908, and a pressure detection module 909 may be connected to the first transmission module 907 and the second transmission module 908. Figure 4 The pressure sensor 407 in FIG. 4 corresponds to the pressure sensor 407 in FIG. 4 , and the beneficial effects achieved in various aspects and corresponding feasible implementation methods are similar and will not be described in detail.

[0135] It will be appreciated that the first transmission module 907 is configured to drive the clamping module 906 to move in a target direction, which includes a direction away from or toward the capacitive touch screen 904 to be tested. The second transmission module 908 is configured to drive the clamping module 906 to move along a preset trajectory on the capacitive touch screen 904 to be tested. The preset pressure range refers to a pressure range within which the absolute value of the difference from the preset pressure does not exceed a certain threshold.

[0136] It is understandable that, in addition to referring to Figure 4In addition to the description of the test system 400 in the embodiment of the present application, the embodiment of the present application can also support other extensions. The first device 901 can be an active capacitive stylus, a passive capacitive stylus, a test needle, or a test column. The preset track can be as follows Figure 6b and 6c The path shown is through each capacitor unit of the capacitive touch screen 904 to be tested, and may also be through some capacitor units of the capacitive touch screen 904 to be tested. The embodiment of the present application does not further limit the shape and structure of the second device 902. Figure 9 A possible implementation of the second device 902 is shown using a three-axis motion platform as an example. The pressure sampling point may include the starting point and / or end point of the preset trajectory, or may not include the starting point and / or end point of the preset trajectory. The preset pressure range may be as follows: Figure 7 The pressure shown is greater than or equal to the preset pressure -A and less than or equal to the preset pressure +A, and can also be other pressure ranges.

[0137] In subsequent use, the test system 900 refers to Figure 4 The calibration test is performed as described in the test system 400.

[0138] In this way, during testing, the test system 900 detects and adjusts the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested, thereby reducing the probability that the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested exceeds a preset pressure range. This helps improve the accuracy of the calibration signal used to determine whether each capacitive unit has been touched, thereby improving the accuracy of the test results of the calibration test.

[0139] In one possible implementation, the second device 902 also includes a limiting mechanism, and the pressure detection module 909 is arranged between the limiting structure and the clamping module 906. The limiting mechanism is used to limit the movement of the pressure detection module 909; the pressure detection module 909 is used to detect the reaction force of the first device 901 when the clamping module 906 clamps the first device 901 and applies pressure to the capacitive touch screen 904 to be tested.

[0140] In this way, the pressure detection module 909 is fixed by the limiting mechanism, which helps the pressure detection module 909 dynamically sense the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested. This helps the test system 900 sense and adjust the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested.

[0141] In one possible implementation, the second device 902 is specifically used to: when the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested is greater than the maximum value in the preset pressure range, drive the clamping module 906 away from the capacitive touch screen to be tested 904 through the first transmission module 907; and / or, when the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested is less than the minimum value in the preset pressure range, drive the clamping module 906 close to the capacitive touch screen to be tested 904 through the first transmission module 907.

[0142] For example, the maximum value in the preset pressure range may be Figure 7 The preset pressure + A shown, the minimum value in the preset pressure range can be as follows Figure 7 Preset pressure shown - A.

[0143] In this way, the first transmission module 907 can drive the clamping module 906 away from or closer to the capacitive touch screen 904 to be tested, which helps reduce the probability that the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested exceeds the preset pressure range. This helps improve the accuracy of the calibration signal when used to determine whether each capacitive unit has been touched, and helps improve the accuracy of the test results of the calibration test.

[0144] In one possible implementation, the second device 902 includes a control module, which is used to control the second transmission module 908 to drive the clamping module 906 to move along a preset trajectory; the control module is also used to obtain the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested from the pressure detection module 909 when the first device 901 is at the pressure sampling point, and when the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested exceeds the preset pressure range, control the first transmission module 907 to drive the clamping module 906 away from or close to the capacitive touch screen 904 to be tested; the preset trajectory includes at least one pressure sampling point.

[0145] It is understandable that the control module may be a controller that is communicatively connected to one or more devices in the test system 900 , or may be other modules that can implement the above control functions.

[0146] In this way, the control module helps to control the movement of the first device 901 and helps to control the movement of the clamping module 906 along a preset trajectory or the adjustment process of the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested.

[0147] In a possible implementation, the testing system 900 further includes a fourth device.

[0148] The fourth device is used to control the second transmission module 908 to drive the clamping module 906 to move along a preset trajectory; the fourth device is also used to obtain the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested from the pressure detection module 909 when the first device 901 is at the pressure sampling point, and when the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested exceeds the preset pressure range, control the first transmission module 907 to drive the clamping module 906 away from or close to the capacitive touch screen 904 to be tested; the preset trajectory includes at least one pressure sampling point.

[0149] It is understandable that the fourth device may be a computer that is communicatively connected to one or more devices in the test system 900 , or may be other terminal devices that can implement the above control functions.

[0150] In this way, the fourth device helps to control the movement of the first device 901 through the clamping module 906, and helps to control the movement of the clamping module 906 along a preset trajectory or the adjustment process of the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested.

[0151] In one possible implementation, the test system is also used to generate an alarm message when the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested is greater than a first preset threshold or less than a second preset threshold; wherein the first preset threshold is greater than the maximum value in the preset pressure range, and the second preset threshold is less than the minimum value in the preset pressure range.

[0152] It is understood that the first preset threshold is the upper limit of the pressure alarm threshold of the test system 900. The second preset threshold is the lower limit of the pressure alarm threshold of the test system 900. For example, the first preset threshold may be the preset pressure + B, and the second preset threshold may be the preset pressure - B. The first and second preset thresholds are not further defined in this embodiment of the present application.

[0153] In this way, the test system 900 can issue an alarm when the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested is greater than the first preset threshold or less than the second preset threshold, which helps to improve the intelligence level of the test system 900.

[0154] In one possible implementation, the third device 903 is used to record the capacitance signal of each capacitor unit 905 in response to the movement of the first device 901 on the capacitive touch screen 904 to be tested; the third device is also used to obtain the difference signal of each capacitor unit through the difference between the capacitance signal and the preset signal.

[0155] It is understandable that the difference signal may be the difference between a preset signal amount under a preset pressure set in the third device 903 and a test signal amount of the capacitance signal of each capacitor unit 905 recorded by the third device 903 .

[0156] In this way, the test system 900 obtains the calibration signal amount of the capacitance signal of each capacitor unit 905 through the difference signal. This helps to improve the accuracy of the calibration signal amount when used to determine whether each capacitor unit has been touched, and helps to improve the accuracy of the test results of the calibration test.

[0157] In one possible implementation, the first transmission module 907 includes a first drive motor and a first transmission mechanism, and the second transmission module 908 includes a second drive motor and a second transmission mechanism. The first drive motor is used to drive the first transmission mechanism to transmit in a target direction, so that the clamping module 906 moves away from or close to the capacitive touch screen 904 to be tested; the second drive motor is used to drive the second transmission mechanism to transmit, so that the clamping module 906 clamps the first device 901 and moves along a preset trajectory on the capacitive touch screen 904 to be tested.

[0158] This helps to achieve the movement of the first device 901 and the movement of the clamping module 906 along a preset track or the adjustment of the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested.

[0159] An embodiment of the present application provides an electronic device, including: a clamping module, a first transmission module, a second transmission module and a pressure detection module.

[0160] It should be understood that the electronic equipment in the embodiments of the present application is Figure 4 The motion platform 402 and Figure 9 The beneficial effects achieved in various aspects and corresponding feasible implementations are similar and will not be described in detail.

[0161] In one possible implementation, the electronic device also includes a limiting mechanism, and the pressure detection module is arranged between the limiting structure and the clamping module, and the limiting mechanism is used to limit the movement of the pressure detection module; the pressure detection module is used to detect the reaction force of the first device when the clamping module clamps the first device and applies pressure to the capacitive touch screen to be tested.

[0162] It should be understood that the limiting mechanism in the embodiment of the present application corresponds to the limiting mechanism in the test system 400 and the limiting mechanism in the test system 900, and the beneficial effects achieved in various aspects and corresponding feasible implementation methods are similar and will not be repeated.

[0163] In one possible implementation, the electronic device is specifically used to: when the pressure applied by the first device to the capacitive touch screen to be tested is greater than the maximum value in a preset pressure range, drive the clamping module away from the capacitive touch screen to be tested through the first transmission module; and / or when the pressure applied by the first device to the capacitive touch screen to be tested is less than the minimum value in the preset pressure range, drive the clamping module close to the capacitive touch screen to be tested through the first transmission module.

[0164] It should be understood that the pressure detection module in the embodiment of the present application is Figure 4 The pressure sensor 407 and Figure 9 The pressure detection module 909 in FIG. 1 corresponds to the pressure detection module 909 in FIG. 1 , and the beneficial effects achieved in various aspects and corresponding feasible implementation methods are similar and will not be described in detail.
