Technical Field

Background

With the development of technology, terminal devices employing capacitive touch screens have been developed. In the use process of the capacitive touch screen, a user can write in the capacitive touch screen by using a handwriting pen frequently, so that handwriting input of terminal equipment adopting the capacitive touch screen is realized. When the sensing conditions of each capacitive unit in the capacitive touch screen to touch are different, the conditions of discontinuous strokes and the like can occur when a user writes in the capacitive touch screen, and the influence on the input experience of the user is large. Therefore, before a terminal device employing a capacitive touch screen leaves a factory, calibration tests are generally performed on each capacitive unit of the terminal device.

In a first aspect, an embodiment of the present application proposes a test system. The test system includes: the device comprises 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 capacitive units.

When the first equipment acts on a capacitance unit of the capacitive touch screen to be tested, the capacitance unit generates an induction signal; the second device comprises a clamping module, a first transmission module, a second transmission module and a pressure detection module; the clamping module is used for clamping first equipment, the first transmission module is used for driving the clamping module to move along a target direction, the target direction comprises a direction far away from or close to the capacitive touch screen to be tested, the second transmission module is used for driving the clamping module to move along a preset track on the capacitive touch screen to be tested, and the pressure detection module is used for detecting the pressure applied by the first equipment on the capacitive touch screen to be tested.

And the second equipment is used for acquiring the pressure applied to the capacitive touch screen to be tested by the first equipment through the pressure detection module in the process that the clamping module clamps the first equipment to move along the preset track on the capacitive touch screen to be tested, and driving the clamping module to move through the first transmission module when the pressure applied to the capacitive touch screen to be tested by the first equipment exceeds the preset pressure range, wherein the pressure applied to the capacitive touch screen to be tested by the moved first equipment is within the preset pressure range.

In this way, the test system detects and adjusts the pressure applied by the first device to the capacitive touch screen to be tested during testing, which is helpful to reduce the probability that the pressure applied by the first device to the capacitive touch screen to be tested exceeds the preset pressure range. Therefore, the accuracy of the calibration signal quantity for judging whether each capacitance unit is touched is improved, and the accuracy of the test result of the calibration test is improved.

In one possible implementation, the second device further includes a limiting mechanism, the pressure detection module is disposed between the limiting mechanism and the clamping module, and the limiting mechanism is configured to limit movement of the pressure detection module; and the pressure detection module is used for detecting the reaction force of the first equipment when the clamping module clamps the first equipment to apply pressure to the capacitive touch screen to be tested.

Therefore, the pressure detection module is fixed through the limiting mechanism, and dynamic sensing of the pressure applied to the capacitive touch screen to be tested by the first equipment is facilitated. Thus, the sensing and adjustment of the pressure applied by the first device 901 to the capacitive touch screen to be tested by the test system is facilitated.

In one possible implementation, the second device is specifically configured to: when the pressure applied by the first equipment to the capacitive touch screen to be tested is larger than the maximum value in the preset pressure range, the first transmission module drives the clamping module to be far away from the capacitive touch screen to be tested; and/or when the pressure applied by the first equipment to the capacitive touch screen to be tested is smaller than the minimum value in the preset pressure range, the clamping module is driven by the first transmission module to approach the capacitive touch screen to be tested.

Therefore, the clamping module can be driven to be far away from or close to the capacitive touch screen to be tested through the first transmission module, and the probability that the pressure applied by the first equipment to the capacitive touch screen to be tested exceeds the preset pressure range is reduced. Therefore, the accuracy of the calibration signal quantity for judging whether each capacitance unit is touched is improved, and the accuracy of the test result of the calibration test is improved.

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

In one possible implementation manner, the test system is further configured to generate alarm information 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 a maximum value in the preset pressure range and the second preset threshold is less than a minimum value in the preset pressure range.

Therefore, the test system can give an alarm when the pressure applied by the first device to the capacitive touch screen to be tested is larger than a first preset threshold value or smaller than a second preset threshold value, and the intelligent degree of the test system is improved.

In one possible implementation manner, a third device is used for responding to the movement of the first device on the capacitive touch screen to be tested and recording the capacitance value signals of each capacitive unit; and the third device is also used for obtaining the difference signal of each capacitor unit through the difference value of the capacitance signal and the preset signal.

Thus, the test system obtains the calibration signal quantity of the capacitance signal of each capacitance unit through the difference signal. Therefore, the accuracy of the calibration signal quantity for judging whether each capacitance unit is touched is improved, and the accuracy of the test result of the calibration test is improved.

Detailed Description

In order to facilitate the clear description of the technical solutions of the embodiments of the present application, some terms and techniques related to the embodiments of the present application are briefly introduced below.

In the embodiments of the present application, the words "first," "second," and the like are used to distinguish between identical or similar items that have substantially the same function and effect. For example, the first chip and the second chip are merely for distinguishing different chips, and the order of the different chips is not limited. It will be appreciated by those of skill in the art that the words "first," "second," and the like do not limit the amount and order of execution, and that the words "first," "second," and the like do not necessarily differ.

It should be noted that, in the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

In the embodiment of the application, the terminal device may be a handheld device with a capacitive touch screen, a vehicle-mounted device, or the like. For example, some terminal devices are: mobile phone, tablet, palm, notebook, mobile internet device (mobile internet device, MID), wearable device, virtual Reality (VR) device, augmented reality (augmented reality, AR) device, etc., to which embodiments of the present application are not limited.

The handwriting pen can be used for handwriting input by a user simply, and particularly, the handwriting pen can provide good input experience for the user when the user records scenes such as notes, drawings and drawings. Whether the terminal equipment adopting the capacitive touch screen supports handwriting pen input and whether the handwriting input function is normal or not have great influence on the input experience of a user. Due to the reasons of the capacitive touch screen production process and the like, the induction conditions of all the capacitive units in the capacitive touch screen to touch are different, for example, some capacitive units are sensitive to touch, and some capacitive units are insensitive to touch, and the conditions of discontinuous strokes and the like when a user writes in the capacitive touch screen can be reflected, so that the terminal equipment adopting the capacitive touch screen usually performs calibration test on all the capacitive units of the terminal equipment before leaving a factory.

Fig. 1 is a schematic structural diagram of a related art test system. As shown in fig. 1, a test system 100 drives a stylus 102 to scribe a capacitive touch screen 103 through a clamping mechanism 101, and performs a capacitive unit calibration test on a terminal device 104 using the capacitive touch screen 103.

It is understood that the capacitive touch screen 103 includes a plurality of capacitive units. When the stylus pen 102 makes a line on each capacitive unit of the capacitive touch screen 103, the x-axis electrode of each capacitive unit of the capacitive touch screen 103 generates an ac signal, and the y-axis electrode of each capacitive unit can sense the ac signal. When the alternating current signal passes through each capacitor unit, each capacitor unit is charged, and the test signal quantity of the capacitance value signal of each capacitor unit is changed.

It should be noted that the terminal device 104 may be provided with a preset signal amount of the capacitance signal of each capacitance unit. The preset signal amount may be a desired signal amount of a capacitance signal of each capacitive unit when the stylus pen 102 scribes a line with a preset pressure on each capacitive unit of the capacitive touch screen 103. The magnitude of the preset signal quantity is related to the magnitude of the preset pressure of the stylus 102 when scribing each capacitive element of the capacitive touch screen 103.

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

At the time of the test, the terminal device 104 may record the test signal amount of the capacitance signal when each capacitance unit is touched by the stylus pen 102. The terminal device 104 may further obtain a difference between the test signal amount of the capacitance signal of each capacitor unit and the preset signal amount of the capacitor unit, where the difference may be referred to as a difference signal amount or an offset signal amount.

It will be appreciated that the differential signal amounts of the capacitive elements in a capacitive touch screen are typically not uniform. This is because the device performance or the generation process of each capacitive unit is different, and the test signal amount of the capacitance signal detected when each capacitive unit is touched is different. The preset signal quantity of the capacitance signal of each capacitance unit in the capacitive touch screen is generally the same, and further the difference between the test signal quantity and the preset signal quantity of the capacitance signal of each capacitance unit is different.

In the subsequent use, the terminal device 104 may calibrate the measured signal amount of the capacitance signal of each capacitance unit through the differential signal amount of each capacitance unit, for example, in the subsequent use of the terminal device 104, if the measured signal amount of the capacitance signal of a certain capacitance unit is detected, the differential signal amount of the capacitance unit may be subtracted based on the detected measured signal amount of the capacitance signal of the capacitance unit, to obtain the calibrated signal amount of the capacitance signal of the capacitance unit, and the calibrated signal amount of the capacitance signal of the capacitance unit is used to determine whether the capacitance unit is touched or not.

However, in the test system 100 in fig. 1, the distances between the stylus pen 102 and the capacitive touch screen 103 may be inconsistent due to the uneven placement of the capacitive touch screen 103 or the tooling error of the stylus pen 102, so that the pressure applied by the stylus pen 102 to the capacitive touch screen 103 may be different. In the case where the pressure applied by the stylus pen 102 to the capacitive touch screen 103 is different, the pressure applied by the stylus pen 102 to the capacitive touch screen 103 may not be consistent with the preset pressure, and the difference signal amount obtained through the preset signal amount cannot truly reflect the difference of the sensing conditions of each capacitive unit to the touch. And the calibration signal quantity obtained after calibrating each capacitor unit through the difference signal is used for judging whether each capacitor unit is not necessarily accurate when touching or not, and the accuracy of the test result of the calibration test of the test system 100 is low.

Fig. 2 is a schematic diagram illustrating different distances between a stylus pen and a capacitive unit according to an embodiment of the present application. As shown in fig. 2, the capacitive unit 201 approaching the capacitive touch screen 103 through the stylus 102, the stylus 102 touching the capacitive unit 201 but not applying pressure, the stylus 102 touching the capacitive unit 201 and applying pressure are illustrated from left to right, respectively.

In some test data, when the stylus pen 102 is close to the capacitive unit 201 of the capacitive touch screen 103 but no touch occurs, the test signal amount of the capacitance signal of the capacitive unit 201 is 6500. When the stylus pen 102 is in contact with the capacitive unit 201 of the capacitive touch screen 103 but no pressure is applied, the test signal amount of the capacitance signal of the capacitive unit 201 is 6800. When the stylus pen 102 is in contact with the capacitive unit 201 of the capacitive touch screen 103 and applies pressure, the test signal amount of the capacitance signal of the capacitive unit 201 is 7400.

It can be seen that the test signal amount of the capacitance signal of the capacitive unit 201 when the stylus pen 102 is in contact with the capacitive unit 201 of the capacitive touch screen 103 is greater than the test signal amount of the capacitance signal of the capacitive unit 201 when the stylus pen 102 is not in contact with the capacitive unit 201 of the capacitive touch screen 103. When the stylus pen 102 is in contact with the capacitive unit 201 of the capacitive touch screen 103, the test signal amount of the capacitance signal of the capacitive unit 201 when the stylus pen 102 applies pressure to the capacitive touch screen 103 is larger than the test signal amount of the capacitance signal of the capacitive unit 201 when the stylus pen 102 does not apply pressure to the capacitive unit 201 of the capacitive touch screen 103.

It will be appreciated that the capacitive touch screen 103 is slightly deformed when the stylus 102 is in contact with and applies pressure to the capacitive element 201 of the capacitive touch screen 103, and that the distance between the stylus 102 and the capacitive element 201 is smaller than when the stylus 102 is not applying pressure to the capacitive touch screen 103.

That is, when the distances between the stylus pen 102 and the capacitance unit 201 are different, the magnitudes of the pressures applied by the stylus pen 102 to the capacitance unit 201 are different, and the magnitudes of the test signal amounts of the capacitance signals of the capacitance unit 201 are different. Therefore, the preset signal amount is an expected signal amount of the capacitance signal of each capacitive unit when the stylus pen 102 applies a preset pressure to the capacitive touch screen 103, and the calibration signal amount is a calibration signal amount when the stylus pen 102 applies a preset pressure to the capacitive touch screen 103. Thus, when 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 calibrates the capacitive unit by using the calibration signal, the situation that handwriting is discontinuous when a user writes on the capacitive touch screen by using the same pressure still occurs, and the user experience is affected.

It can be understood that when the sensing conditions of the plurality of capacitive units of the capacitive touch screen 103 on the touch are different, the stylus pen 102 applies the same pressure to the plurality of capacitive units of the capacitive touch screen 103, and the magnitude of the test signal of the capacitance signals of the plurality of capacitive units is different.

Fig. 3 is a schematic diagram illustrating a stylus pen according to an embodiment of the present application applying the same pressure to a plurality of capacitive units of a capacitive touch screen. As shown in fig. 3, the capacitive touch screen 103 includes a first capacitive unit 301, a second capacitive unit 302, and a third capacitive unit 303, and the first capacitive unit 301, the second capacitive unit 302, and the third capacitive unit 303 of the capacitive touch screen 103 are scribed with the same pressure by the stylus 102.

In some test data, when a pressure of 0.1 kilogram force per square centimeter (kgf/cm) is applied to the first, second, and third capacitance units 301, 302, and 303, respectively, by the stylus pen 102, the test signal amounts of the capacitance signals of the first, second, and third capacitance units 301, 302, and 303 are 6500, 7700, and 5500, respectively.

It can be seen that when the same amount of pressure is applied to the first capacitance unit 301, the second capacitance unit 302, and the third capacitance unit 303 by the stylus pen 102, the magnitude of the test signal of the capacitance signals of the first capacitance unit 301, the second capacitance unit 302, and the third capacitance unit 303 is different due to the difference in the sensing conditions of the first capacitance unit 301, the second capacitance unit 302, and the third capacitance unit 303 to the touch.

In summary, the above-described test system 100 has the following drawbacks:

in the test process, the pressure applied by the stylus pen 102 to the capacitive touch screen 103 may be different due to factors such as uneven placement of the capacitive touch screen 103 or tooling errors of the stylus pen 102, so that the pressure applied by the stylus pen 102 to the capacitive touch screen 103 may not be consistent with the preset pressure. The difference signal quantity obtained through 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 of the sensing condition of each capacitor unit to touch. And the calibration signal quantity obtained after calibrating each capacitor unit through the difference signal is used for judging whether each capacitor unit is not necessarily accurate when touching or not, and the accuracy of the test result of the calibration test of the test system 100 is low.

In view of the foregoing, embodiments of the present application provide a test system, an electronic device, and a control method. The pressure sensor is arranged in the test system, so that the pressure applied by the handwriting pen on the capacitive touch screen is detected, and the pressure applied by the handwriting pen on the capacitive touch screen is adjusted, thereby being beneficial to reducing the deviation between the pressure applied by the handwriting pen to the capacitive touch screen and the preset pressure. Therefore, the accuracy of the calibration signal quantity for judging whether each capacitance unit is touched is improved, and the accuracy of the test result of the calibration test is improved.

The test system of the present application is further described below with reference to the drawings and examples.

Fig. 4 is a schematic structural diagram of a test system according to an embodiment of the present application. As shown in fig. 4, the test system 400 includes: stylus 401, motion platform 402, and terminal device 403, terminal device 403 comprising capacitive touch screen 404. The motion stage 402 includes a clamping mechanism 405, a motion device 406, and a pressure sensor 407. The holding mechanism 405 is used to hold the stylus 401.

When the test system 400 performs a test, the movement device 406 drives the clamping mechanism 405 to drive the stylus 401 to scribe a line on the capacitive touch screen 404 along a preset track, so as to perform a capacitance unit calibration test on the terminal device 403 using the capacitive touch screen 404. The pressure sensor 407 is used for collecting pressure applied by the stylus 401 to the capacitive touch screen 404, and when the stylus 401 moves to a pressure sampling point on a preset track, the test system 400 obtains the pressure applied by the stylus 401 to the capacitive touch screen 404 from the pressure sensor 407.

Furthermore, 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 does not exceed a certain threshold, the movement device 406 drives the clamping mechanism 405 to move along the preset track, and the stylus 401 continues to move the scribing line on the capacitive touch screen 404 along the preset track. 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 the certain threshold, the moving device 406 drives the clamping mechanism 405 to be away from or close to the capacitive touch screen 404, and the stylus 401 is away from or close to the capacitive touch screen 404. The magnitude of the certain threshold is not further limited in the embodiments of the present application.

It will be appreciated that by the stylus 401 moving away from or closer to the capacitive touch screen 404, the pressure applied by the stylus 401 to the capacitive touch screen 404 becomes greater or smaller until the absolute value of the difference between the pressure applied by the stylus 401 to the capacitive touch screen 404, acquired by the pressure sensor 407, and the preset pressure does not exceed the certain threshold.

Fig. 5 is a schematic diagram of a capacitive unit of a capacitive touch screen according to an embodiment of the present application. As shown in fig. 5, the capacitive touch screen 404 includes a plurality of capacitive units 501.

It will be appreciated that the predetermined 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 capacitance unit 501. At the time of the test, the terminal device 403 may record the test signal amount of the capacitance signal when each capacitance unit 501 is touched by the stylus pen 401.

In a subsequent use, the terminal device 403 may obtain the difference signal by a difference between the test signal amount of the capacitance signal of each capacitance unit and the preset signal amount. In the subsequent use of the terminal device 403, the calibration signal quantity of the capacitance signal of each capacitance unit 501 is obtained by the difference between the measurement signal quantity and the difference signal quantity of the capacitance signal of each capacitance unit 501, and the calibration signal quantity of the capacitance signal of each capacitance unit 501 is used to determine whether or not each capacitance unit 501 is touched, and the like.

In this way, the test system 400 obtains the pressure applied by the stylus 401 to the capacitive touch screen 404 from the pressure sensor 407 at the time of testing and adjusts the pressure applied by the stylus 401 to the capacitive touch screen 404 through the motion platform 402 so that the absolute value of the difference from the preset pressure does not exceed a certain threshold. Thus, it is helpful to reduce the deviation of the pressure applied by the stylus 401 to the capacitive touch screen 404 from the preset pressure. Therefore, the accuracy of the calibration signal quantity for judging whether each capacitance unit is touched is improved, and the accuracy of the test result of the calibration test is improved.

In the embodiment of the present application, the shape, structure and clamping manner of the clamping mechanism 405 are not limited. The clamping mechanism 405 may be a side-lock type clamping mechanism, a chuck type clamping mechanism, a spring-clip type clamping mechanism, a hydraulic type clamping mechanism, or the like. The shape and structure of the motion platform 402 are not limited in the embodiment of the present application, as long as the stylus 401 can be driven by the clamping mechanism 405 to scribe on the capacitive touch screen 404 and get away from or get close to the capacitive touch screen 404.

In a possible implementation manner, the conductive layer of the capacitive touch screen 404 provided in this embodiment of the present application is provided with M rows of x-axis electrodes and N columns of y-axis electrodes, where the x-axis electrodes and the y-axis electrodes form a capacitance at the intersection, so as to form m×n capacitance units 501 of the capacitive touch screen 404.

In this embodiment, the preset track is set according to the arrangement condition of the capacitive units 501 of the capacitive touch screen 404. The shape of the preset track is not limited in the embodiment of the application.

In one possible implementation, the pressure sampling point may include a start point of a preset trajectory.

It can be appreciated that when the pressure sampling point does not include the start point of the preset track, the test system 400 cannot learn and adjust the pressure applied by the stylus 401 to the capacitive touch screen 404 from the pressure sensor 407 when the stylus 401 is between the start point of the preset track and the first sampling point, so that 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 is increased.

In this way, when the stylus 401 moves to the start 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. And further, the pressure applied by the stylus 401 to the capacitive touch screen 404 is adjusted, so that the probability that the absolute value of the difference value between the pressure applied by the stylus 401 to the capacitive touch screen 404 and the preset pressure exceeds a certain threshold value is reduced, and the accuracy of the test result of the calibration test is improved.

In one possible implementation, the pressure sampling points may not include an endpoint of the preset trajectory.

It will be appreciated that when stylus 401 moves to the end of the preset trajectory, stylus 401 is no longer marking, and test system 400 need not learn from pressure sensor 407 and adjust the pressure applied by stylus 401 to capacitive touch screen 404. Thus, the test time is reduced, and the test efficiency is improved.

In one possible implementation, the preset trajectory may include a plurality of pressure sampling points.

It is understood that the distance between two adjacent pressure sampling points may be the product of the speed at which the motion device 406 moves along the predetermined trajectory and the sampling time interval of the pressure sampling points. The sampling time interval of the pressure sampling point may refer to a time interval in which the test system 400 obtains the pressure applied by the stylus 401 to the capacitive touch screen 404 from the pressure sensor 407. The distance between pressure sampling points may be proportional to the sampling time interval when the speed at which the motion device 406 moves along the preset trajectory is constant.

In one possible implementation, the distance between the pressure sampling points may be a pressure sampling step size.

Fig. 6a is a schematic diagram of a pressure sampling point according to an embodiment of the present application. As shown in fig. 6a, the pressure sampling points may include a start point 601 of a preset trajectory and a pressure sampling point 602. The distance between the start point 601 of the preset trajectory and the pressure sampling point 602 may be a pressure sampling step 603.

It will be appreciated that the speed of movement and sampling time interval at which the movement device 406 moves along the predetermined trajectory may be set according to the efficiency and accuracy requirements of the calibration test. For example, when the efficiency of the calibration test requires high accuracy and low accuracy, the moving speed of the movement device 406 may be set to 1.5mm/s and the sampling time interval may be 5s. For example, when the efficiency of the calibration test requires low accuracy, the moving speed of the movement device 406 may be set to 0.5mm/s, and the sampling time interval may be 2s.

Fig. 6b is a schematic diagram illustrating a pressure sampling point according to another embodiment of the present application. As shown in fig. 6b, when the capacitive touch screen 404 includes a plurality of capacitive units 501, the preset trace 604 passes through each capacitive unit 501 of the capacitive touch screen 404, and the preset trace 604 includes a plurality of pressure sampling points 605.

It is understood that the pressure sampling points 605 may be the same as the number of the respective capacitance units 501 and correspond one to one. Fig. 6b illustrates one possible implementation, taking one pressure sampling point 605 per capacitive unit 501 as an example.

In this way, the pressure sampling points 605 may correspond to each capacitor unit 501, and 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 during testing, which is beneficial to improving the accuracy of the test result of the calibration test of the test system 400.

Fig. 6c is a schematic diagram illustrating a pressure sampling point according to another embodiment of the present application. As shown in fig. 6c, when the capacitive touch screen 404 includes a plurality of capacitive units 501, the preset track 606 passes through each capacitive unit 501 of the capacitive touch screen 404, and the preset track 606 includes a plurality of pressure sampling points 607.

It will be appreciated that the number of pressure sampling points 607 may be less than the number of capacitive units 501 when the efficiency of the calibration test requires high accuracy. For example, one pressure sampling point 607 may be provided every one capacitor unit 501, or one pressure sampling point 607 may be provided every several capacitor units 501. The number and location of the pressure sampling points 607 are not further limited in the embodiments of the present application. Fig. 6c illustrates one possible implementation with one pressure sampling point 607 set up for two capacitive units 501 per interval.

Thus, when the number of pressure sampling points 607 is smaller than the number of capacitance units 501, the number of times of judging whether the pressure applied by the stylus 401 to the capacitance units 501 exceeds a certain threshold in the test is reduced, and thus the number of times of pressure adjustment may be reduced. The test time is shortened, and the test efficiency of the test system 400 is improved.

Exemplary, FIG. 7 is a schematic diagram of a pressure regulation strategy of a test system provided in one embodiment of the present application. As shown in fig. 7, 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 to the capacitive touch screen 404 when the absolute value of the difference between the pressure applied by the stylus 401 to 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 to the capacitive touch screen 404 when the absolute value of the difference between the pressure applied by the stylus 401 to the capacitive touch screen 404 exceeds a and 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 to the capacitive touch screen 404 and P exceeds B.

It is understood that not exceeding a by an absolute value of the difference from P means P-a, p+a. The absolute value of the difference from P exceeding A and not exceeding B means [ P-B, P-A ]. U.P+A, P+B ].

It will be appreciated that stylus 401 may also stop scribing when the absolute value of the difference between the pressure applied by stylus 401 to capacitive touch screen 404 and the preset pressure exceeds B.

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 degree of intellectualization of the calibration test and the accuracy of the test result.

In one possible implementation, the motion device 406 includes a drive module and a movement module. The driving module can be a servo motor or a stepping motor. The driving mode of the driving module can be mechanical driving, hydraulic driving or electric driving. The moving module can be any one of a linear moving module, a rotary moving module, a multi-degree-of-freedom moving module or a parallel moving module, and can also be formed by combining a plurality of moving modules. The conventional linear movement module comprises a triaxial movement module, and a movement device on which the triaxial movement module is mounted is a triaxial movement device. By way of example, fig. 4 illustrates one possible implementation of the movement device 406 with a three-axis movement device.

It will be appreciated that the tri-axial motion device moves the clamping mechanism 405 along the x, y and/or z axes, thereby moving the stylus 401 away from or toward the capacitive touch screen or moving the scribe line along a predetermined trajectory on the capacitive touch screen 404. The shape and structure of the movement device 406 are not limited in this embodiment, so long as the movement device can drive the clamping mechanism 405 to move, thereby driving the handwriting pen 401 to scribe on the capacitive touch screen 404 and driving the handwriting pen 401 to be far away from or close to the capacitive touch screen 404.

In a possible implementation, the motion platform 402 further includes a limiting mechanism, and the pressure sensor 407 is disposed between the limiting mechanism and the clamping mechanism 405, and movement of the pressure sensor 407 is limited by the limiting mechanism. When the holding mechanism 405 holds the stylus pen 401 to apply pressure to the capacitive touch panel 404, the pressure sensor 407 detects the pressure applied to the capacitive touch panel 404 by the stylus pen 401 by the reaction force applied to the stylus pen 401 by the capacitive touch panel 404.

In the embodiment of the present application, the shape and structure of the limiting mechanism are not limited, and may be a limiting protrusion, a limiting post, a limiting groove, or the like, as long as the movement of the pressure sensor 407 can be limited. The pressure sensor 407 converts the detected pressure applied by the stylus 401 to the capacitive touch screen 404 into a pressure signal. The test system 400 obtains a pressure signal from the pressure sensor 407, and determines whether 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 value.

In this way, the pressure sensor 407 can be fixed by the limit mechanism, and the pressure sensor 407 can detect the pressure applied by the stylus 401 to the capacitive touch screen 404. Thus, the sensing of the amount of pressure applied by stylus 401 to capacitive touch screen 404 by test system 400 is facilitated.

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

In this way, the test system 400 can 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 intelligentization degree of the test system 400.

In one possible implementation, the movement device 406 and the clamping mechanism 405 stop moving 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, and the stylus 401 stops scribing.

In this way, the probability of the test system 400 performing a calibration test in the event of a pressure anomaly is reduced, thereby helping to improve the accuracy of the test results of the test system 400. Meanwhile, the probability that the handwriting pen 401 is used for scribing under the condition of overlarge pressure so as to scratch the capacitive touch screen 404 can be reduced, and the service life of the capacitive touch screen 404 can be prolonged.

In one possible implementation, the movement of the movement device 406 and the clamping mechanism 405 stops when the number of times the stylus 401 is adjusted by moving the stylus 401 away from or closer to the capacitive touch screen 404 to apply pressure to the capacitive touch screen 404 is greater than a certain threshold, and the stylus 401 stops scribing.

In this embodiment of the present application, the certain threshold is an upper limit of the number of pressure adjustments. The number of times the clamping mechanism 405 drives the stylus 401 to move away from or approach the capacitive touch screen 404 exceeds the certain threshold, and 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 does not exceed another certain threshold, the problem may be caused by too large pulse equivalent of the movement device 406 or failure of the test system 400.

It will be appreciated that where the movement module of the movement device 406 is a linear movement module, the pulse equivalent refers to the distance moved by the gripping mechanism 405. When the movement module of the movement device 406 is a rotary movement module, the pulse equivalent refers to the angle by which the holding mechanism 405 rotates. When the drive module of the motion device 406 is a stepper motor, the magnitude of the pulse equivalent is proportional to the step size of the stepper motor.

It will be appreciated that when the pulse equivalent of the movement device 406 is too large, the distance moved or the rotation angle of the clamping mechanism 405 is too large, so that the pressure applied by the stylus 401 to the capacitive touch screen 404 cannot be adjusted to the absolute value of the difference from the preset pressure does not exceed another certain threshold.

Thus, when the number of times the test system 400 adjusts the clamping mechanism to drive the stylus 401 away from or towards the capacitive touch screen 404 exceeds a certain threshold, the stylus 401 stops scribing. Thereby reducing the probability of the test system 400 making an invalid adjustment in the event of an excessive pulse equivalent or failure of the test system 400.

In one possible implementation, the movement modules of the movement device 406 include a first movement module and a second movement module, and the driving module of the movement device 406 includes a first driving motor for driving the first movement module and a second driving motor for driving the second movement module. The first moving module is used for driving the clamping mechanism 405 to move along a direction away from or close to the capacitive touch screen 404, and the second moving module is used for driving the clamping mechanism 405 to move along a preset track.

In this way, movement of stylus 401 of test system 400 is facilitated, and movement of clamping mechanism 405 along a preset trajectory or adjustment of the pressure applied by stylus 401 to capacitive touch screen 404 is facilitated.

In a possible implementation manner, 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 driving motor and the second driving motor are stepping motors.

In this way, movement of stylus 401 of test system 400 along the z-axis or in the xy-plane is facilitated, and movement of clamping mechanism 405 along a preset trajectory or adjustment of the pressure applied by stylus 401 to capacitive touch screen 404 is facilitated.

Fig. 8 is a schematic structural diagram of a stylus according to an embodiment of the present application. As shown in fig. 8, stylus 401 includes code electrodes 801.

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

In this way, the test system 400 can correct the pressure applied by the stylus 401 to the capacitive touch screen 404 through the pressure perceived by the pen tip in the coding signal, which is helpful for reducing the deviation between the pressure applied by the stylus 401 to the capacitive touch screen 404 and the preset pressure. Thus, the accuracy of the test result of the calibration test is facilitated to be improved.

Illustratively, after the capacitive touch screen is subjected to the calibration test using the test system 100 in the related art, the standard deviation of the test signal amounts of the capacitance signals of the plurality of capacitive units of the capacitive touch screen is 4N. After the test system 400 provided in the embodiment of the present application is used to perform a calibration test on the capacitive touch screen, the standard deviation of the test signal amounts of the capacitance signals of the plurality of capacitive units of the capacitive touch screen is N. Wherein N is a positive integer.

Fig. 9 is a schematic structural diagram of a test system according to another embodiment of the present application. As shown in fig. 9, another embodiment of the present application provides a test system 900, including: a first device 901, a second device 902 and a third device 903, the third device 903 comprising a capacitive touch screen 904 to be tested.

It can be appreciated that the first device 901 in the embodiment of the present application may correspond to the stylus 401 in fig. 4 and 8, the second device 902 may correspond to the motion platform 402 in fig. 4, the third device 903 may correspond to the terminal device 403 in fig. 4, the capacitive touch screen 904 to be tested may correspond to the capacitive touch screen 404 in fig. 4 to 7, and the advantages obtained by the aspects and the corresponding possible embodiments are similar and are not repeated.

The second apparatus 902 includes a clamping module 906, a first transmission module 907, a second transmission module 908, and a pressure detection module 909.

It is understood that the clamping module 906 may correspond to the clamping mechanism 405 in fig. 4, the movement device 406 in fig. 4 may include a first transmission module 907 and a second transmission module 908, and the pressure detection module 909 may correspond to the pressure sensor 407 in fig. 4, so that the advantages obtained by the aspects and the corresponding possible embodiments are similar and are not repeated.

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

It is understood that embodiments of the present application may support additional extensions in addition to those described with respect to test system 400 in FIG. 4. The first device 901 may be an active capacitive pen, a passive capacitive pen, a test needle and a test column. The preset track may be routed to each capacitive unit of the capacitive touch screen 904 to be tested as shown in fig. 6b and 6c, or may be routed to a portion of the capacitive units of the capacitive touch screen 904 to be tested. The shape and structure of the second device 902 are not further limited in this embodiment, and fig. 9 illustrates one possible implementation of the second device 902 using a three-axis motion platform as an example. The pressure sampling points may or may not include the start point and/or the end point of the preset trajectory. The preset pressure range may be greater than or equal to the preset pressure-a and less than or equal to the preset pressure + a as shown in fig. 7, but may be another pressure range.

In subsequent use, the test system 900 performs a calibration test with reference to the description of the test system 400 in FIG. 4.

In this way, the test system 900 detects and adjusts the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested during testing, helping to reduce 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. Therefore, the accuracy of the calibration signal quantity for judging whether each capacitance unit is touched is improved, and the accuracy of the test result of the calibration test is improved.

In one possible implementation, the second device 902 further includes a limiting mechanism, where the pressure detection module 909 is disposed between the limiting mechanism and the clamping module 906, the limiting mechanism being configured to limit movement of the pressure detection module 909; a pressure detection module 909 for detecting a reaction force of the first device 901 when the clamping module 906 clamps the first device 901 to apply pressure to the capacitive touch screen 904 to be tested.

In this way, the pressure detection module 909 is fixed by the limiting mechanism, which helps to realize dynamic sensing of the pressure applied by the first device 901 to the capacitive touch screen 904 screen to be tested by the pressure detection module 909. Thus, the sensing and adjustment of the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested by the test system 900 is facilitated.

In a possible implementation manner, the second device 902 is specifically configured 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, the clamping module 906 is driven by the first transmission module 907 to be far away from the capacitive touch screen 904 to be tested; and/or, when the pressure applied by the first device 901 to the capacitive touch screen to be tested 904 is smaller than the minimum value in the preset pressure range, the clamping module 906 is driven by the first transmission module 907 to approach the capacitive touch screen to be tested 904.

For example, the maximum value in the preset pressure range may be the preset pressure +a as shown in fig. 7, and the minimum value in the preset pressure range may be the preset pressure-a as shown in fig. 7.

In this way, the first transmission module 907 may drive the clamping module 906 away from or close to the capacitive touch screen 904 to be tested, which is helpful to 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. Therefore, the accuracy of the calibration signal quantity for judging whether each capacitance unit is touched is improved, and the accuracy of the test result of the calibration test is improved.

In a possible implementation manner, the second device 902 includes a control module, where the control module is configured to control the second transmission module 908 to drive the clamping module 906 to move along a preset track; the control module is further configured to, when the first device 901 is at the pressure sampling point, obtain, from the pressure detection module 909, a pressure applied by the first device 901 to the capacitive touch screen 904 to be tested, and when a pressure applied by the first device 901 to the capacitive touch screen 904 to be tested exceeds a preset pressure range, control the first transmission module 907 to drive the clamping module 906 to be far away from or near the capacitive touch screen 904 to be tested; the preset trajectory includes at least one pressure sampling point.

It will be appreciated that the control module may be a controller communicatively coupled to one or more devices in the test system 900, or may be other modules that implement the control functions described above.

In this way, the control module helps control the movement of the first device 901 and helps 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.

In one possible implementation, the test system 900 further includes a fourth device.

A fourth device, configured to control the second transmission module 908 to drive the clamping module 906 to move along a preset track; the fourth device is further configured to, when the first device 901 is at the pressure sampling point, obtain, from the pressure detection module 909, a pressure applied by the first device 901 to the capacitive touch screen 904 to be tested, and when a pressure applied by the first device 901 to the capacitive touch screen 904 to be tested exceeds a preset pressure range, control the first transmission module 907 to drive the clamping module 906 to be far away from or near the capacitive touch screen 904 to be tested; the preset trajectory includes at least one pressure sampling point.

It will be appreciated that the fourth device may be a computer communicatively coupled to one or more devices in the test system 900, or may be other terminal devices that may implement the control functions described above.

In this way, the fourth device facilitates control of the movement of the first device 901 by the gripping module 906 and control of the movement of the gripping module 906 along a preset trajectory or adjustment of the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested.

In a possible implementation manner, the test system is further configured to generate alarm information 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 a maximum value in the preset pressure range and the second preset threshold is less than a minimum value in the preset pressure range.

It is appreciated that the first predetermined threshold is the upper pressure alarm threshold of the test system 900. The second preset threshold is the lower pressure alarm threshold of the test system 900. For example, the first preset threshold may be a preset pressure +b and the second preset threshold may be a preset pressure-B. The first preset threshold value and the second preset threshold value are not further limited.

In this way, the test system 900 may 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 intelligentization degree of the test system 900.

In a possible implementation manner, the third device 903 is configured to record a capacitance signal of each capacitive unit 905 in response to the movement of the first device 901 on the capacitive touch screen 904 to be tested; and the third device is also used for obtaining the difference signal of each capacitor unit through the difference value of the capacitance signal and the preset signal.

It is understood that the difference signal may be a difference between a preset signal amount at a preset pressure set in the third device 903 and a test signal amount of the capacitance value signal of each capacitance unit 905 recorded by the third device 903.

Thus, the test system 900 obtains the calibration signal amount of the capacitance signal of each capacitance unit 905 from the difference signal. Therefore, the accuracy of the calibration signal quantity for judging whether each capacitance unit is touched is improved, and the accuracy of the test result of the calibration test is improved.

In a possible implementation, the first transmission module 907 includes a first driving motor and a first transmission mechanism, and the second transmission module 908 includes a second driving motor and a second transmission mechanism, where the first driving motor is configured to drive the first transmission mechanism to transmit in a target direction, so that the clamping module 906 is far from or near to the capacitive touch screen 904 to be tested; the second driving motor is used for driving the second transmission mechanism to transmit, so that the clamping module 906 clamps the first device 901 to move along a preset track on the capacitive touch screen 904 to be tested.

In this way, movement of the first device 901 is facilitated and movement of the clamping module 906 along a preset trajectory or adjustment of the pressure applied by the first device 901 to the capacitive touch screen 904 to be tested is facilitated.
