Detailed Description
For the purpose of promoting a better understanding of the objects, aspects and advantages of the present disclosure, reference is made to the following detailed description taken in conjunction with the accompanying drawings.

"upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
For display devices with touch control function, such as mobile phones, tablet/notebook computer and other display device products, the touch control performance of the screen needs to be tested in the product development process.
The touch performance test of the display device comprises a touch scribing test of the display device. When performing a touch scribing test, a test probe is usually used to complete a touch performance test on a display device to be tested along a test path in a horizontal, vertical, or diagonal direction of the display device.
However, the conventional touch test equipment is used for testing the flat type touch display device. To novel curved surface display device, for example install in the curved surface display device that has bigger size and include incurved curved surface, outer curved surface, incurved + incurved compound curved surface and other heterotypic curved surfaces or arc structure in the cockpit in on-vehicle demonstration field, adopt traditional touch-control test equipment can't carry out the touch-control and rule out the test.
For the foregoing reasons, the present disclosure provides a touch performance testing method for a curved surface display device. As shown in fig. 1, the touch performance testing method includes:
and S101, acquiring three-dimensional shape measurement data of the curved surface display device to be measured.
The curved surface display device to be tested comprises a curved surface display panel, a touch panel, a display control unit and a touch control unit, wherein the display control unit and the touch control unit are bound on a frame of the curved surface display device to be tested; the display control unit is connected with the curved surface display panel and is used for controlling the display content of the curved surface display panel; the touch control unit is connected with the touch panel, and when the curved surface display device to be tested is subjected to touch operation, the touch panel receives touch information and the touch control unit processes the touch information, so that touch data are obtained.
In this embodiment, the three-dimensional shape measuring device may be used to measure the three-dimensional shape of the curved surface display device to be measured, so as to obtain the three-dimensional shape measurement data of the curved surface display device to be measured. The three-dimensional shape measurement data comprises surface three-dimensional profile information of the curved surface display device to be measured, so that the real three-dimensional size data of the curved surface display device to be measured can be represented.
The three-dimensional topography measuring device adopts a non-contact three-dimensional topography measuring method and technology, including but not limited to laser three-dimensional scanning technology, structured light imaging technology and other measuring technologies. Optionally, since the structured light-based three-dimensional topography measurement technology has the advantages of non-contact, high measurement speed, high precision, easiness in carrying out automatic measurement under the control of a computer, and the like, the structured light imaging technology can be adopted in the embodiment to realize the rapid three-dimensional measurement and reconstruction of the curved surface display device to be measured.
Optionally, the structured light three-dimensional measurement method includes, but is not limited to, methods and techniques of stacked grating profilometry, fourier transform profilometry, phase profilometry, modulation degree profilometry, speckle projection profilometry, and the like.
Step S102, touch data of a test probe on the curved surface display device to be tested is obtained, and a first position coordinate of the test probe on the curved surface display device to be tested is calculated based on the touch data and the three-dimensional shape measurement result.
After the touch performance test is started, the test probe performs touch operation on the curved surface display device to be tested along a preset path. When the test probe is in contact with the curved surface display device to be tested to realize a touch function, for a current touch point, the touch panel and the touch control unit can calculate touch data corresponding to the test probe at the touch point, and since the touch data reflects the relative position between the test probe and the curved surface display device to be tested, the three-dimensional shape measurement result reflects the real three-dimensional size data of the curved surface display device to be tested, so that the three-dimensional coordinate position, namely the first position coordinate, of the test probe on the curved surface display device to be tested can be obtained based on the touch data and the three-dimensional shape measurement result. In this embodiment, the first position coordinates are obtained based on a calculation result of the touch control unit.
Step S103, obtaining a second position coordinate when the test probe is located at the touch point corresponding to the touch data.
In this embodiment, when the obtained test probe is located at the touch point, the three-dimensional position coordinate of the test probe is calculated to obtain the second position coordinate. Wherein the second position coordinate is the actual position coordinate of the test probe.
And step S104, obtaining a touch performance test result of the curved surface display device to be tested based on the first position coordinate and the second position coordinate.
In this embodiment, after obtaining the first position coordinate based on the calculation result of the touch control unit and obtaining the second position coordinate of the test probe on the curved surface display device to be tested, the error between the first position coordinate and the second position coordinate can be calculated, so as to obtain the touch performance test result.
In this embodiment, the real and accurate three-dimensional shape, physical size and coordinate information of the curved surface display device to be tested are obtained by obtaining the three-dimensional shape measurement data of the curved surface display device to be tested, the first position coordinate of the test probe on the curved surface display device to be tested is calculated based on the three-dimensional shape measurement data, and the touch performance test result of the curved surface display device to be tested is obtained by combining the second position coordinate of the test probe on the curved surface display device to be tested, so that the scribing touch performance test can be performed on various curved surface display screens.
In some embodiments, the multi-point coordinates on the curved surface display device to be tested can be measured by contacting the test probe with the curved surface display device to be tested for multiple times, so as to calculate and fit a curved surface track equation, and the test path of the test probe is predicted according to the curved surface track equation. However, this method is only suitable for testing horizontal or vertical simple paths, and due to the problems of touch accuracy, actual touch points cannot be predicted, and the error of the actual touch points on the non-predicted trajectory is difficult to calculate, so that the test result is inaccurate, and the curved surface display device or the test equipment to be tested may be damaged. For example, a bump exists at a certain position on the curved surface display device to be tested, and the predicted track does not cover the position, so that the test probe may collide with the curved surface display device to be tested during measurement, and the curved surface display device to be tested or the test equipment is damaged.
Therefore, in some embodiments of the present disclosure, a pretest path of the test probe on the curved surface display device to be tested may be calculated based on the three-dimensional topography measurement result; and controlling the test probe to move according to the pre-test path to determine the touch point.
In this embodiment, even if the screen of the curved surface display device to be tested is a complex irregular structure, since the three-dimensional topography measurement result includes the surface three-dimensional profile information of the curved surface display device to be tested, a pretest path of the test probe can be obtained based on the surface three-dimensional profile information of the curved surface display device to be tested, the pretest path not only includes simple paths such as horizontal or vertical paths, but also includes various complex paths, the pretest path can cover all positions of the surface of the curved surface display device to be tested, and no uncovered touch report points exist; meanwhile, when the pretest path is calculated, the test probe does not need to be in contact with the curved surface display device to be tested. Therefore, the touch performance test of the pretest path obtained by adopting the method can improve the touch accuracy, and the damage of the curved surface display device to be tested or the test equipment caused by the collision between the test probe and the display device can be avoided.
In some optional embodiments, the calculating the first position coordinate of the test probe on the curved surface display device to be tested based on the touch data and the three-dimensional topography measurement result in step S102 includes:
step S201, obtaining a two-dimensional position coordinate of the touch point on the curved surface display device to be measured.
Step S202, calculating the first position coordinate based on the two-dimensional position coordinate and the three-dimensional topography measurement result.
As shown in fig. 2, when testing a flat display device, a two-dimensional coordinate system O2 may be constructed based on two adjacent right-angle sides of the flat display device, and then a touch control unit may calculate and obtain a report point coordinate P of a test probei(xi,yi) And the point reporting coordinate of the test probe is a two-dimensional coordinate. Because the touch control unit cannot identify whether the display device to be tested is a screen or a curved surface, the display device to be tested can be uniformly used as a plane screen to output touch report point coordinates, and therefore, only two-dimensional coordinates can be obtained.
As shown in fig. 3, when the test equipment is used to test a curved display device, the touch control unit needs to calculate and obtain the coordinates f (x, y, z) of the three-dimensional test probe at the position of the touch point. Therefore, the test equipment can be used for firstly obtaining the two-dimensional position coordinates f (x, y) of the touch point on the curved surface display device to be tested, and then calculating by combining the three-dimensional shape measurement result obtained by the previous calculation, so that the report point coordinates f (x, y, z), namely the first position coordinates, of the three-dimensional test probe can be obtained.
In other optional embodiments, the calculating the first position coordinate of the test probe on the curved surface display device to be tested based on the touch data and the three-dimensional topography measurement result in step S102 includes:
and S301, constructing an actual physical size model based on the three-dimensional shape measurement result and a preset three-dimensional coordinate system.
In this embodiment, after obtaining the three-dimensional shape measurement result, an actual physical size model may be constructed according to a preset three-dimensional coordinate system O1. As shown in fig. 3, in a specific embodiment, a corner of the curved display device to be tested may be used as an origin of the three-dimensional coordinate system O1, two sides connected to the origin and perpendicular to each other may be used as xy-axes, and a plane perpendicular to the xy-axes may be used as z-axis, and the curved display device to be tested may be located in the first quadrant of the three-dimensional coordinate system O1 as much as possible for calculation. Thus, the actual physical size model of the curved surface display device to be measured can be obtained based on the three-dimensional coordinate system O1 and the three-dimensional shape measurement result, so that the three-dimensional coordinates of each position point on the curved surface display device to be measured can be obtained based on the actual physical size model.
Alternatively, the three-dimensional coordinate system may also be constructed at any position relative to the curved surface display device to be measured, for example, the center, four corners, or any other position of the curved surface display device to be measured.
Step S302, determining the two-dimensional position coordinates of the touch point based on the three-dimensional coordinate system.
Step S303, calculating the first position coordinate based on the two-dimensional position coordinate and the actual physical size model.
After the plane display device is processed into a curved surface display device, the point reporting coordinates of the test probes on the plane display device can be in one-to-one correspondence with the point reporting coordinates of the test probes on the curved surface display device. However, the three-dimensional shape measurement data of the curved screen obtained by the three-dimensional shape measurement device and the actual physical dimension model are established in a three-dimensional coordinate system, and the touch control unit calculates the coordinates of the touch probe report point to be established in a two-dimensional coordinate system, so that the two-dimensional position coordinates f (x, y) of the touch point are obtained based on the two-dimensional coordinate system formed by the xy axes in the three-dimensional coordinate system, and then the calculated two-dimensional position coordinates are converted into the three-dimensional coordinates f (x, y, z) in the three-dimensional coordinate system by combining with the actual physical dimension model, namely the first position coordinates.
In other optional embodiments, the touch performance testing method further includes: the second position coordinate is determined based on a displacement of the test probe in XYZ directions relative to the three-dimensional coordinate system.
In this embodiment, the second position coordinate, which is the actual position coordinate of the test probe, is obtained by calculating the displacement of the test probe. For example, the second position coordinates of the test probe are obtained by calculating the displacement of the test probe in the XYZ direction by calculating the respective movement distances of the test probe in the x direction, the y direction, and the z direction with reference to the three-dimensional coordinate system. Or, constructing a reference coordinate system of the test probe, wherein an x axis, a y axis and a z axis of the reference coordinate system can be respectively parallel to the x axis, the y axis and the z axis of the three-dimensional coordinate system, an origin of the reference coordinate system is different from the origin of the three-dimensional coordinate system, obtaining a first displacement based on a difference between the reference coordinate system and the three-dimensional coordinate system, obtaining a second displacement based on a displacement difference relative to the reference coordinate system when the test probe moves, and obtaining a displacement of the test probe relative to the three-dimensional coordinate system in an XYZ direction based on a sum of the first displacement and the second displacement, thereby obtaining a second position coordinate.
Optionally, before the obtaining of the touch data of the test probe on the curved surface display device to be tested in step S102, the method further includes: and calibrating the test probe and the curved surface display device to be tested. In this embodiment, before the first position coordinate and the second position coordinate are obtained, the test probe and the curved surface display device to be tested need to be calibrated first, so that the final touch performance test result is prevented from being inaccurate due to the position error of the test probe and the curved surface display device before the touch performance test starts. The test probe can be aligned to a vertex of the curved surface display device to be tested, such as the origin of a three-dimensional coordinate system, so that the calibration of the test probe and the curved surface display device to be tested is realized; or, Mark points can be arranged on the edge of the curved surface display device to be tested, and calibration and the like of the test probe and the curved surface display device to be tested can be realized through the identification of the Mark points by the test probe.
In other optional embodiments, the obtaining a touch performance test result of the curved surface display device to be tested based on the first position coordinate and the second position coordinate in step S103 includes:
step S401, calculating the shortest distance between the first position coordinate and the second position coordinate along the surface of the curved surface display device to be measured.
Step S402, obtaining a touch performance test result of the curved surface display device to be tested based on the shortest distance of the touch points.
As shown in FIG. 2, for the plane display device, the point report coordinate P of the test probe is calculatedi(xi,yi) And the actual physical position coordinates P of the test probeo(xo,yo) Error d betweeniAnd obtaining a touch performance test result, wherein i is the number of test points. Wherein the content of the first and second substances,
passing error diOr reflecting the touch performance test result by the value of the Accuracy.
In the application, because the surface of the curved surface display device to be measured is not a plane, the shortest distance between the first position coordinate and the second position coordinate is directly calculated, and the error between the first position coordinate and the second position coordinate cannot be reflected obviously. Therefore, in this embodiment, the error between the first position coordinate and the second position coordinate is obtained by calculating the shortest distance Di between the two position coordinates along the surface of the curved surface display device to be measured, and then, for n points of the scribing test, the Accuracy is calculated to be max (D) based on the maximum value of the shortest distance Di1,D2,…Di,…,Dn,). Based on the shortest distance Di or the precision Accuracy, various touch performance parameters such as Accuracy, linearity, precision, jitter and the like of the curved surface display device to be tested can be obtained, and therefore a touch performance test result is obtained.
In the touch performance testing method of the curved surface display device in this embodiment, a non-contact three-dimensional topography measuring device is used to measure three-dimensional topography measurement data of a curved surface display device to be tested, an actual physical size model is constructed based on the three-dimensional topography measurement data to obtain a first position coordinate of a test probe on the curved surface display device to be tested, a second position coordinate is obtained based on displacement of the test probe, and a touch performance testing result is obtained by calculating the shortest distance between the first position coordinate and the second position coordinate along the surface of the curved surface display device to be tested; the method can realize the scribing touch performance test of various different curved surface display devices, does not damage a screen or test equipment during the test, and can improve the test precision.
It should be noted that the method of the embodiments of the present disclosure may be executed by a single device, such as a computer or a server. The method of the embodiment can also be applied to a distributed scene and completed by the mutual cooperation of a plurality of devices. In such a distributed scenario, one of the devices may only perform one or more steps of the method of the embodiments of the present disclosure, and the devices may interact with each other to complete the method.
