Detailed Description
For the purposes of promoting an understanding of the principles and advantages of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same.
It should be noted that unless otherwise defined, technical or scientific terms used in the embodiments of the present disclosure should be given the ordinary meaning as understood by one of ordinary skill in the art to which the present disclosure pertains. The terms "first," "second," and the like, as used in embodiments of the present disclosure, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
For display devices with touch function, such as mobile phones, tablet/notebook computers, etc., touch 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 on the display device. When performing a touch scribing test, a test probe is generally used to complete a touch performance test on a display device along a test path in a horizontal, vertical or diagonal direction of the display device to be tested.
However, conventional touch testing devices are used for testing flat touch display devices. For a novel curved surface display device, for example, a curved surface display device which is installed in a cockpit in the vehicle-mounted display field, has a larger size and comprises an inner curved surface, an outer curved surface, an inner curved surface and an outer curved composite curved surface and other special-shaped curved surfaces or arc structures, and cannot be subjected to touch scribing test by adopting conventional touch testing equipment.
For the above reasons, the present disclosure provides a touch performance testing method for a curved display device. As shown in fig. 1, the touch performance testing method includes:
step S101, obtaining three-dimensional shape measurement data of a curved surface display device to be measured.
The curved surface display device to be tested comprises a curved surface display panel, a touch panel, and a display control unit and a touch control unit which are bound on the frame of the curved surface display device to be tested; the display control unit is connected with the curved display panel and used for controlling the display content of the curved 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 control information is received through the touch panel and processed through the touch control unit, so that touch data are obtained.
In this embodiment, the three-dimensional morphology measuring device may be used to measure the three-dimensional morphology of the curved surface display device to be measured, so as to obtain three-dimensional morphology measurement data of the curved surface display device to be measured. The three-dimensional shape measurement data comprise surface three-dimensional contour information of the curved surface display device to be measured, so that real three-dimensional size data of the curved surface display device to be measured can be represented.
The three-dimensional morphology measuring device adopts a non-contact three-dimensional morphology measuring method and technology, including but not limited to laser three-dimensional scanning technology, structured light imaging technology and other measuring technologies. Optionally, because the three-dimensional morphology measurement technology based on structured light has the advantages of non-contact, high measurement speed, high precision, easy implementation of automatic measurement under computer control and the like, the embodiment can realize rapid three-dimensional measurement and reconstruction of the curved surface display device to be measured by adopting the structured light imaging technology.
Alternatively, structured light three-dimensional measurement methods include, but are not limited to, cascade profilometry, fourier transform profilometry, phase measurement profilometry, modulation measurement profilometry, speckle projection profilometry, and the like.
Step S102, touch control 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 control data and the three-dimensional morphology 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 the current touch point, the touch control panel and the touch control unit can calculate touch data corresponding to the test probe at the touch point, and as 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, and thus 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 coordinate is obtained based on the calculation result of the touch control unit.
Step S103, obtaining a second position coordinate of the test probe when the test probe is located at the touch point corresponding to the touch data.
In this embodiment, when the 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. The second position coordinate is the actual position coordinate of the test probe.
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 the first position coordinate obtained based on the calculation result of the touch control unit and the second position coordinate of the test probe on the curved surface display device to be tested are obtained, 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 morphology, physical size and coordinate information of the curved surface display device to be tested are obtained by obtaining the three-dimensional morphology measurement data of the curved surface display device to be tested, then the first position coordinate of the test probe on the curved surface display device to be tested is calculated based on the three-dimensional morphology measurement data, and then 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 scribing touch performance test can be performed on various curved surface display screens.
In some embodiments, the test path of the test probe is predicted according to the curve trajectory equation by measuring the coordinates of multiple points on the curve display device to be tested through multiple contacts of the test probe with the curve display device to be tested so as to calculate and fit the curve trajectory equation. However, this method is only suitable for testing simple paths such as horizontal paths or vertical paths, and due to the problems of touch accuracy and the like, the actual touch report point cannot be predicted, and the error of the actual touch report point on the non-predicted track 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 damage to the curved surface display device to be tested or the test equipment is caused.
Thus, in some embodiments of the present disclosure, a pre-test path of the test probe on the curved display device under test may be calculated based on the three-dimensional topography measurements; and controlling the test probe to move according to the pre-test path so as to determine the touch point.
In this embodiment, even if the screen of the curved surface display device to be tested is of a complex special-shaped structure, since the three-dimensional shape measurement result includes the three-dimensional surface profile information of the curved surface display device to be tested, a pre-test path of the test probe can be obtained based on the three-dimensional surface profile information of the curved surface display device to be tested, and the pre-test path not only includes simple paths such as horizontal or vertical paths, but also includes various complex paths, and the pre-test path can cover all positions of the surface of the curved surface display device to be tested, and no uncovered touch control report points exist; meanwhile, when the pre-test path is calculated, the test probe is not required to be in contact with the curved surface display device to be tested. Therefore, the touch performance test of the pre-test path obtained by the method can improve the touch accuracy, and the damage to the curved surface display device or the test equipment to be tested caused by the collision between the test probe and the display device can not be caused.
In some optional embodiments, the calculating, in step S102, 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 shape measurement result includes:
step S201, obtaining two-dimensional position coordinates of the touch point on the curved surface display device to be tested.
Step S202, calculating the first position coordinate based on the two-dimensional position coordinate and the three-dimensional morphology measurement result.
As shown in fig. 2, when testing a flat panel display device, the conventional testing apparatus can construct a two-dimensional coordinate system O2 based on two adjacent right-angle sides of the flat panel display device, and then calculate and obtain the test probe report point coordinate P through a touch control unit i (x i ,y i ) And the reporting point coordinates of the test probe are two-dimensional coordinates. Because the touch control unit can not identify the display device to be testedThe screen or the curved surface can be uniformly used as a plane screen to output touch control report point coordinates, so that only two-dimensional coordinates can be obtained.
As shown in fig. 3, when the curved display device is tested by using the testing apparatus, the touch control unit needs to calculate and obtain the coordinates f (x, y, z) of the point reported by the three-dimensional test probe where the touch point is located. Therefore, the testing equipment can be utilized to obtain the two-dimensional position coordinate f (x, y) of the touch point on the curved surface display device to be tested, and then the three-dimensional shape measurement result obtained by previous calculation is combined to calculate, so that the three-dimensional test probe point reporting coordinate f (x, y, z), namely the first position coordinate, can be obtained.
In other optional embodiments, the calculating, in step S102, 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 includes:
step S301, an actual physical size model is constructed based on the three-dimensional morphology measurement result and a preset three-dimensional coordinate system.
In this embodiment, after the three-dimensional morphology measurement result is obtained, 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 surface display device to be measured 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, a plane perpendicular to the xy axes may be used as a z axis, and in addition, for convenience in calculation, the curved surface display device to be measured may be located in the first quadrant of the three-dimensional coordinate system O1 as much as possible. 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 morphology measurement result, and the three-dimensional coordinate 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 be constructed at any position with respect to the curved surface display device to be measured, for example, at 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.
When the planar display device is processed and manufactured into the curved surface display device, the test probe reporting point coordinates on the planar display device can be in one-to-one correspondence with the test probe reporting point coordinates on the curved surface display device. However, the three-dimensional shape measurement data of the curved surface screen obtained by measurement of the three-dimensional shape measurement device and the actual physical size model are built under a three-dimensional coordinate system, and the point coordinates of the test probe calculated by the touch control unit are built under a two-dimensional coordinate system, so that the two-dimensional position coordinates f (x, y) of the touch point are obtained firstly based on the two-dimensional coordinate system formed by 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) under the three-dimensional coordinate system by combining the actual physical size model, namely the first position coordinates.
In other optional embodiments, the touch performance testing method further includes: the second position coordinates are determined based on displacement of the test probe in XYZ directions relative to the three-dimensional coordinate system.
In the present embodiment, the actual position coordinates of the test probe, i.e., the second position coordinates, are obtained by calculating the displacement of the test probe. For example, the displacement of the test probe in the XYZ direction is calculated by calculating the moving distances of the test probe in the x direction, the y direction and the z direction respectively based on the three-dimensional coordinate system, thereby obtaining the second position coordinate of the test probe. Alternatively, a reference coordinate system of the test probe is constructed, the x-axis, the y-axis, and the z-axis of the reference coordinate system may be parallel to the x-axis, the y-axis, and the z-axis of the three-dimensional coordinate system, respectively, an origin of the reference coordinate system is different from an origin of the three-dimensional coordinate system, a first displacement is obtained based on a difference between the reference coordinate system and the three-dimensional coordinate system, a second displacement is obtained based on a displacement difference with respect to the reference coordinate system when the test probe moves, and a displacement of the test probe in an XYZ direction with respect to the three-dimensional coordinate system is obtained based on a sum of the first displacement and the second displacement, thereby obtaining a second position coordinate.
Optionally, before the step S102 of obtaining touch data of the test probe on the curved surface display device to be tested, 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, calibration needs to be performed on the test probe and the curved surface display device to be tested, so as to avoid inaccurate final touch performance test results caused by position errors of the test probe and the curved surface display device before the touch performance test starts. The test probe can be aligned with one vertex of the curved surface display device to be tested, for example, 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 identification of the test probe to the Mark points.
In other optional embodiments, the step S103 of obtaining the touch performance test result of the curved surface display device to be tested based on the first position coordinate and the second position coordinate includes:
and 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 tested.
Step S402, obtaining a touch performance test result of the curved display device to be tested based on the shortest distances of the touch points.
As shown in fig. 2, for the flat panel display device, the test probe point coordinates P are calculated i (x i ,y i ) Actual physical position coordinates P of test probe o (x o ,y o ) Error d between i To obtain the touch performance test result, i is the number of test point bits. Wherein,
by error ofd i Or the value of the precision Accuracy reflects the touch performance test result.
In this application, since the surface of the curved display device to be measured is not a plane, directly calculating the shortest distance between the first position coordinate and the second position coordinate obviously cannot reflect the error between the two. Therefore, in the present embodiment, the error between the first position coordinate and the second position coordinate is obtained by calculating the shortest distance Di of the first position coordinate and the second position coordinate along the surface of the curved surface display device to be measured, and then for n points of the scribing test, the Accuracy accuracy=max (D 1 ,D 2 ,…D i ,…,D n ,). Based on the shortest distance Di or the precision Accurcry, 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 thus a touch performance test result is obtained.
According to the touch performance testing method of the curved surface display device, a non-contact three-dimensional morphology measuring device is adopted to measure three-dimensional morphology measuring data of the curved surface display device to be tested, an actual physical size model is constructed based on the three-dimensional morphology measuring data so as 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 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 performed 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 is completed by mutually matching a plurality of devices. In the case of such a distributed scenario, one of the devices may perform only one or more steps of the methods of embodiments of the present disclosure, the devices interacting with each other to accomplish the methods.
It should be noted that the foregoing describes some embodiments of the present disclosure. Other embodiments are within the scope of the following claims.
