Test method of folding screen, electronic equipment and device

Technical Field

The application relates to the technical field of nondestructive testing, in particular to a testing method of a folding screen, electronic equipment and a device.

Background

The foldable screen is a screen made of a flexible material and capable of displaying images, and is generally mounted on a foldable device, such as a foldable mobile phone, and the foldable mobile phone changes the form of the display screen by folding and unfolding, so as to provide a plurality of display modes for users.

However, in the use process of the folding screen, the folding screen is frequently folded and unfolded, which may cause creases on the surface of the screen, even the phenomenon of internal liquid leakage, and not only affects the aesthetic feeling of the folding screen, but also affects the display effect of the folding screen, and even also affects the service life of the folding screen, resulting in poor user experience.

Therefore, when the folding screen is produced, the folding times of the folding screen need to be detected, and the folding screen is ensured not to have the phenomena of crease marks, even liquid leakage and the like after being used for a few times.

Disclosure of Invention

In order to solve the above problems, the present application provides a method for testing a foldable screen, an electronic device and an apparatus. In the folding screen testing method, distances from each pixel point to a certain plane in an area after a folding screen is folded are different, and the distances from the pixel points in a general concave area to the certain plane are larger than the distances from the pixel points in the area without the folding screen to the certain plane, and the distances from the pixel points in a convex area to the certain plane are smaller than the distances from the pixel points in the area without the folding screen to the certain plane. This is explained below.

In a first aspect, the present application provides a method for testing a foldable screen, which is applied to an electronic device, where the electronic device includes a laser sensor, and the method includes: the method comprises the steps that the electronic equipment controls a laser sensor to emit laser test signals to a test screen in an unfolded state, the distance from each pixel point on the test screen to the electronic equipment is obtained, and whether the test screen is folded or not is determined according to the distance from each pixel point on the test screen to the electronic equipment, wherein the current folding times of the test screen are N, and N is a positive integer; and determining that the number of pixels corresponding to the difference between the distance from each pixel point on the test screen to the electronic equipment and the preset distance is larger than or equal to a first threshold value exceeds a first preset number, and taking the current folding times N of the test screen as the maximum folding times of the test screen.

The test screen refers to a folding screen in each implementation mode of the application. In some implementations, the number of the laser sensors may be one or more, and in the case of multiple laser sensors, the form of the laser sensors may be a dot matrix, a linear array, or the like, which is not limited in this application.

In some implementations, the preset distance is a preset distance value hereinafter, and is set by a tester according to a requirement, generally depending on a distance between the foldable screen and the electronic device when no crease or liquid leakage occurs. The first threshold value is an empirical value or an experimental value.

It will be appreciated that in the case of no crease or leakage on the folded screen, the distance between each pixel on the folded screen and the electronic device should be the same, or the difference in distance between the pixel on the folded screen and the electronic device should be within a certain range, for example (-0.00001 cm, +0.00001 cm).

And when folding screen has the crease, because unevenness's the condition can appear in the crease region, so lead to the distance between each pixel of crease region and the electronic equipment and not have the regional each pixel of crease to the distance between the electronic equipment different, moreover, as above says, the pixel of general depressed area is big apart from this distance of confirming the plane for the pixel of the region that does not take place the crease apart from this distance of confirming the plane, and the pixel of protruding region apart from this distance of confirming the plane for the pixel of the region that does not take place the crease apart from this distance of confirming the plane for the distance of confirming the plane.

Therefore, the distance between each pixel point on the folding screen and the electronic equipment can be utilized to determine whether the folding screen has creases. Specifically, when the number of points, in which the difference between the distance between each pixel point and the electronic device and the preset distance is greater than the first threshold, exceeds a first preset number, it may be indicated that a fold appears in the folded screen, and the folding times corresponding to the fold screen at this time are the maximum folding times of the folded screen, that is, the folding times in the following text. Finally, whether the folding screen meets the factory-leaving requirement or not can be judged by comparing the folding times with the folding times (namely, a second threshold value) of the factory-leaving requirement of the folding screen, so that the situation that the display effect of the folding screen is influenced by the folding marks of the folding screen and the user experience is influenced due to the fact that the user only uses the folding screen for several times is avoided.

With reference to the first aspect, in a possible implementation manner of the first aspect, the method further includes: the method comprises the steps that the number of folding times of a test screen is increased by 1, the electronic device controls the test screen to be folded and unfolded again, the electronic device controls a laser sensor to emit laser test signals to the test screen in an unfolded state, the distance from each pixel point on the test screen to the electronic device is obtained, whether creases appear on the test screen is determined according to the distance from each pixel point on the test screen to the electronic device, and the current folding times of the test screen is N +1.

In some implementation manners, for the case that no crease is detected in the folded screen after the nth folding, the folded screen is continuously folded, that is, the folding frequency of the folded screen is increased by 1, and then whether a crease occurs in the folded screen is detected by using the same method.

With reference to the first aspect and the foregoing possible implementation manners, in another possible implementation manner, the test screen includes a plurality of detection regions, and a distance from each pixel point on the test screen to the electronic device includes: and in a plurality of detection areas in the test screen, the distance from the central pixel point of each detection area to the electronic equipment. That is, in some implementation manners, the test screen may be divided into a plurality of test areas, each test area includes a plurality of pixel points, and accordingly, the distance from each pixel point on the test screen to the electronic device may be the distance from the central pixel point of each test area to the electronic device in the test area. By the mode, the folding screen can be tested by taking the detection area as a unit, and the testing efficiency of the folding screen is improved.

With reference to the first aspect and the foregoing possible implementation manners, in another possible implementation manner, the electronic device further includes a camera, and the method further includes: acquiring a first image of the test screen under a first test condition through the camera corresponding to the difference between the distance from each pixel point on the test screen to the electronic equipment and the preset distance, wherein the difference is larger than or equal to a first threshold value and smaller than a first preset number, and acquiring a first display parameter according to the first image; and comparing the similarity between a first display parameter of the first image and a second display parameter of a preset image under the first test condition, determining whether the test screen has a liquid leakage phenomenon according to the similarity between the first display parameter and the second display parameter, determining that the test screen has the liquid leakage phenomenon corresponding to the similarity between the first display parameter and the second display parameter being smaller than a similarity threshold value, and taking the current folding frequency N of the test screen as the maximum folding frequency of the test screen.

The phenomenon of crease and leakage generally occur simultaneously, namely in the case of crease, the phenomenon of leakage generally occurs and vice versa. Moreover, the leakage phenomenon also affects the display effect of the folding screen, as shown in fig. 4b below. Therefore, the test method for the folding screen can also detect whether the folding screen has a liquid leakage phenomenon.

Specifically, according to the method for testing the folding screen, whether the liquid leakage phenomenon occurs in the folding screen is determined by comparing the similarity between the reference image (namely, the second image) corresponding to the absence of the liquid leakage phenomenon and the test image (namely, the first image) corresponding to the presence of the liquid leakage phenomenon under the same test condition. If the similarity of the two images is higher than the similarity threshold, the test image is similar to the reference image, namely the leakage phenomenon occurs in the folding screen, and if the similarity of the two images is lower than the similarity threshold, the test image is not similar to the reference image, namely the leakage phenomenon does not occur in the folding screen.

More specifically, in some implementation manners, the method for testing the folding screen can determine whether the folding screen has a liquid leakage phenomenon according to the similarity between the display parameters of the test image and the reference image. Namely, the similarity between the test image and the reference image is determined according to the first display parameter of the test image and the second display parameter of the reference image.

In some implementations, if it is determined that the folding screen has no crease, whether a leakage phenomenon occurs in the folding screen can be continuously detected, and then the folding times of the folding screen corresponding to the leakage phenomenon are used as the maximum folding times of the folding screen. And then, similarly, determining whether the folding screen meets factory requirements or not according to the maximum folding times of the folding screen corresponding to the leakage phenomenon of the folding screen, so as to avoid the situation that the leakage phenomenon of the folding screen affects the user experience after the user only uses the folding screen for several times.

In some implementation manners, whether the folding screen has a crease or not and whether the liquid leakage phenomenon occurs or not may also be detected respectively, so as to obtain the corresponding maximum folding times when the folding screen has the crease and the corresponding maximum folding times when the liquid leakage phenomenon occurs. This is not limited by the present application.

Detailed Description

The application provides a test method of a folding screen, electronic equipment and a device. Various aspects of the illustrative embodiments will be described using terms commonly employed by those skilled in the art. In the description of the embodiments herein, "/" means "or" unless otherwise specified, for example, a/B may mean a or B; "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A or B exists at the same time, and B exists alone. In addition, in the description of the implementation of the present application, "a plurality" means two or more than two.

In the following, the terms "first", "second" and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", "third" may explicitly or implicitly include one or more of the features.

As mentioned above, in the use process of the folding screen, the folding screen is frequently folded or unfolded, which may cause the surface of the screen to have creases or even cause the phenomenon of leakage of the internal liquid (hereinafter referred to as leakage phenomenon), thereby affecting the beauty and display effect of the folding screen, or even affecting the service life of the folding screen, and causing poor user experience. The liquid leakage phenomenon refers to that the luminescent materials such as liquid crystal and the like in the screen slowly leak out of the screen sealing layer, and is represented as the phenomenon that the screen gradually has abnormal color and gradually expands range, and even spreads to the whole screen.

This will be explained below using the folding handset shown in fig. 1a as an example.

As shown in fig. 1a, a folding screen handset 1 has an outer screen 10 and an inner screen 20. When the foldable screen mobile phone 1 is in the unfolded state, the external screen 10 can display time information, power information, network information, and the like, as shown in fig. 1 b. The inner screen 20 can display icon information, time information, power information, network information, and the like of each application installed on the folding-screen mobile phone 1, as shown in fig. 1 c. The application programs include, but are not limited to, notes 101, video application 102, order application 103, clock 104, game application 105, weather 106, comment application 107, chat application 108, settings 109, and the like. It is understood that the information displayed on the outer screen 10 or the inner screen 20 is exemplary, and in other implementations, other information may be displayed on the outer screen 10 and the inner screen 20 of the folding-screen mobile phone 1, which is not limited in this application.

Taking the inner screen 20 of the folding-screen mobile phone 1 as an example, in the process that the folding-screen mobile phone 1 is frequently folded or unfolded, a crease appears on the surface of the inner screen 20, and in general, the crease is at the rotating shaft of the folding-screen mobile phone 1. For example, as shown in fig. 2, a fold L1 appears at the pivot 210 of the inner screen 20 of the folding screen handset 1. It can be understood that the appearance of the fold can deform the image display at the fold, which affects the display effect of the folding screen mobile phone 1.

Fig. 3a shows an image display effect when the area S1 in fig. 2 has no crease and no leakage according to an embodiment of the present application. Fig. 3b shows an image display effect after the S1 region in fig. 2 is creased according to an embodiment of the present application. As shown in fig. 3a, the icon of the video application 102 is normally displayed, whereas the icon of the video application 102 in fig. 3b cannot be normally displayed due to the effect of the crease.

Also, in addition to the creases, leakage may occur during frequent folding and unfolding.

Fig. 4a shows the display effect of the S1 region in fig. 2 without liquid leakage and crease according to the embodiment of the present application. Fig. 4b shows a display effect after liquid leakage occurs in the region S1 in fig. 2 according to an embodiment of the present application. As shown in fig. 4a, the icon of the video application 102 is normally displayed, while the icon of the video application 102 in fig. 4b cannot be normally displayed due to the leakage, and the S1 area is affected by the leakage, and the spot appears.

Both of the above situations will undoubtedly affect the image display effect of the folding screen mobile phone 1.

Therefore, in some implementation manners, in order to ensure that the folding screen mobile phone 1 does not have a crease or even a liquid leakage phenomenon after being used for several times, the folding screen is tested before the folding screen leaves the factory, and whether the folding times of the folding screen meet the factory requirements is determined. The folding times of the folding screen refer to the times corresponding to the screen of the folding screen when the screen is folded and unfolded and the liquid leakage phenomenon or the crease occurs. It can be understood that below the number of foldings, the screen of the folding screen will not leak or crease.

Specifically, a tester collects optical images of the inner screen and the outer screen of the folding screen by using a detection device, and then analyzes the optical images of the inner screen and the outer screen of the folding screen by using an image recognition method to determine whether creases exist on the inner screen and the outer screen of the folding screen. However, this method is only suitable for the case where the fold is obvious (for example, the fold in the S1 region shown in fig. 3 a), and the fold which is not obvious cannot be detected only by analyzing the optical image.

In order to solve the technical problem, the application provides a test method of a folding screen.

In the method of the application, after the surface of the folding screen is provided with the crease, the crease can be uneven, and at this time, the distance from each point of the crease to a certain determined plane is not the same any more. In some implementations, the determination plane is a plane in which a detection device used by a tester to detect whether a fold exists in the folded screen is located. More specifically, the determination plane may be a plane formed by an exit point of the detection apparatus from which the test signal exits.

For ease of understanding, the folding screen shown in fig. 5 will be described by taking the fold L1 at the inner screen 20 as an example. As shown in fig. 5, the detection device 500 is disposed opposite to the inner screen 20 of the folding screen in the unfolded state, the laser sensor 510 of the detection device 500 emits a laser test signal to the inner screen 20 of the folding screen, and the detection device 500 may determine the distance from each pixel point on the inner screen 20 of the folding screen to the detection device 500 according to the time difference between the emission of the laser test signal and the reflection of the laser test signal by the inner screen 20 of the folding screen. More specifically, the distance between each pixel point on the inner screen 20 of the folding screen and the determined plane 2 where the exit point of the distance measuring module 510 (i.e. the exit point of the laser sensor 510') for exiting the laser test signal is located.

As shown in fig. 5, since the fold at L1 is uneven, the distance between each pixel point at L1 and the pixel point in the other area of the inner panel 20 is different from the distance between the determination plane 2 and the pixel point. More specifically, fig. 6 is a partially enlarged view of the area S2 in fig. 5, and it can be seen that the distances D2, D3, D4 from the determination plane 2 of the points C, D, E at the fold L1 are significantly different from the distances D1, D1 from the points a, B on the inner screen 20 without the fold to the determination plane 2, and D2, D3, D4 are all larger than D1.

In order to more clearly understand the solution of the present application, a schematic structural diagram of a detection apparatus 700 according to the solution of the present application is described below with reference to fig. 7.

As shown in fig. 7, the detection apparatus 700 includes a ranging module 710, a camera module 720, a control module 730, and a processing module 740.

The distance measuring module 710 is configured to detect distances from each point in the folding-screen mobile phone 1 to the determination plane 2. In some implementations, the determination plane 2 may be determined by a tester according to requirements, and in general, as mentioned above, the determination plane 2 refers to a plane where an exit point of a device or the like for measuring distance on the detection apparatus 700 is located, for example, a plane where an exit point of the laser sensor 510' in fig. 6 is located.

In some implementations, the ranging module 710 may be implemented in software or hardware. As an example of hardware, the ranging module 710 may be one or more laser sensors, and in case the ranging module 710 is a plurality of laser sensors, the ranging module 710 may be a laser ranging lattice composed of the plurality of laser sensors. For example, as shown in fig. 8, the distance measuring module 710 is a 1 × N laser distance measuring line array composed of N laser sensors 510'. In some implementations, the laser sensor may also be an m × n area array, and it should be understood that the arrangement of the laser sensor is not limited by the present application. Wherein m and n are both empirical or experimental values, for example, m may be 10, n may be 20, which is not limited in this application.

Taking the distance measuring module 710 as an example of a laser distance measuring lattice, when the laser distance measuring lattice measures the distance of the folding screen mobile phone 1, each laser sensor 510 'transmits a laser signal to the outer screen 20 (or the inner screen 10) of the folding screen mobile phone 1, and a corresponding laser receiver (in some implementations, the laser receiver may be a laser sensor itself) receives the laser signal reflected by the outer screen 20 of the folding screen mobile phone 1, and then the distance between the measured point and the laser sensor 510' is determined according to the time difference between the two and the propagation speed of the laser (generally, the light speed).

In some implementations, the distance measuring module 710 may also process the optical signal of the laser sensor 510 'to obtain a corresponding electrical signal, and send the electrical signal to the processing module 740, and the processing module 740 obtains the distance from the measured point to the laser sensor 510' according to the electrical signal, which is not limited in this application.

The camera module 720 is configured to obtain optical images of the inner and outer screens of the folding-screen mobile phone 1, so that the processing module 740 determines whether the liquid leakage occurs in the folding-screen mobile phone 1 by analyzing the optical images of the inner and outer screens. In some implementations, the camera module 720 may also be implemented in software or hardware. As an example of hardware, the camera module 720 may be a camera module 520 (CCM) including a lens (1 ens), a sensor (sensor), a Flexible Printed Circuit (FPC), and a Digital Signal Processor (DSP). Light collected by an object (for example, a folding screen mobile phone 1) through a lens (1 ens) is converted into an electrical signal through an integrated circuit such as a Complementary Metal Oxide Semiconductor (CMOS) or a charge-coupled device (CCD), and the electrical signal is converted into a digital image signal through an internal image processor (ISP) and then output to a DSP for processing and conversion into an image signal in a standard RGB or YUV format. In some implementations, the camera module 720 sends the acquired optical image signals of the inner and outer screens of the folding-screen mobile phone 1 to the processing module 740, and the processing module 740 analyzes the optical image signals to determine whether the inner and outer screens of the folding-screen mobile phone 1 have a liquid leakage phenomenon. In some implementations, the relative positions of the camera module 520 as the camera module 720 and the laser sensor 510 as the ranging module 710 may be as shown in fig. 5 above, i.e., the camera module 510 is disposed above the laser sensor 510, but it should be understood that the present application is not limited to the relative position arrangement of the two.

The control module 730 is used to control the position of the ranging module 710. In some implementations, it is understood that the area measured by the ranging module 710 at one time is limited, and in order to measure the distance from a point on the folding screen mobile phone 1 to the determination plane 2 as much as possible, the control module 730 may control the ranging module 710 to move up and down left and right to cover the whole area of the inner screen 20 or the outer screen 10 of the folding screen mobile phone 1. In some implementations, the control module 730 may control the distance measuring module 710 (e.g., the laser sensor 510) to move up and down through the automatic retracting mechanism 530 shown in fig. 5, which is not limited in this application. The moving path of the ranging module 710 is controlled by the control module 730, and may be preset and set by a tester, or the tester may input a moving instruction to the control module 730 in real time to control the movement of the ranging module 710, which is not limited in this application. In other implementation manners, the control module 730 may further control the folding and unfolding of the foldable screen mobile phone 1 after each distance measurement is finished, so as to detect the next folding times.

In some implementations, the processing module 740 is configured to perform analysis according to data corresponding to the optical image output by the camera module 720, and determine whether a liquid leakage phenomenon occurs in the inner screen 10 or the outer screen 20 of the folding-screen mobile phone 1. Or is configured to determine whether a crease appears on the screen of the folding-screen mobile phone 1 according to the distance from each point on the inner and outer screens of the folding-screen mobile phone 1, output by the distance measuring module 710, to the detecting device 700. The specific determination process will be described below with reference to fig. 9.

The structure of the apparatus 700 is merely exemplary, and in other implementations, the apparatus 700 may further include more modules, such as a storage module, which is not limited in this application. In addition, in some implementations, the functions of the control module 710 and the processing module 740 may also be combined and disposed in the control module 710 or the processing module 740, which is not limited in this application.

Based on the above detection device, in the method of the present application, the distance from each pixel point on the inner screen 10 and the outer screen 20 of the folding screen mobile phone 1 to the detection device 700 may be detected by the distance measurement module 710 of the detection device 700, and whether the screen of the folding screen mobile phone 1 has a crease is determined by determining whether the number of points, whose difference between the distance from the inner screen 10 and the outer screen 20 of the folding screen mobile phone 1 to the detection device 700 and the preset distance value exceeds the first threshold value, exceeds the first preset number. Compared with an image analysis method which cannot detect an unobvious crease, the method can more accurately determine whether the crease appears on the screen of the folding screen mobile phone 1.

The preset distance value is the distance from the preset detection device 700 to the folding screen mobile phone 1, and can be set by a tester as required. The first threshold is an empirical value, and is determined by the distance from the detecting device 700 to the folding screen mobile phone 1, and can be set by a tester according to needs. The first predetermined amount is also an empirical value. This is not limited by the present application.

In some implementations, each point on the screen of the folding screen handset 1 refers to each pixel point on the screen of the folding screen handset 1. In other implementations, each point on the screen of the folding-screen mobile phone 1 may also be a detection area formed by a plurality of pixel points (e.g., 100), or each point on the screen of the folding-screen mobile phone 1 may be an area that can be measured by a single laser sensor 710' in the ranging module 710 in the detection device 700 at a time, for example, an area that can be measured by a single laser sensor in the aforementioned laser sensor lattice at a time, it can be understood that the measurable area generally corresponds to a plurality of pixel points. This is not limited by the present application.

Under the condition that the screen of the folding screen mobile phone 1 is determined to have the crease, the folding times of the folding screen mobile phone 1 at the moment are recorded and taken as the folding times. And finally, judging whether the folding times of the folding screen exceeds a second threshold value or not so as to determine whether the folding screen meets the factory requirements or not. The second threshold is also an empirical value or an experimental value, and the value of the second threshold may be, for example, 1000 times, which is not limited in the present application.

Therefore, after the crease of the screen of the folding screen mobile phone 1 is accurately detected by using the above method, the folding times of the folding screen mobile phone 1 can be further accurately determined, and whether the folding screen mobile phone 1 meets the factory requirements or not can be accurately judged according to the folding times, so that the condition that the crease appears on the screen of the folding screen mobile phone 1 after the folding screen mobile phone 1 is used for a plurality of times by a user is avoided, and the user experience is improved.

In addition, since the liquid leakage phenomenon can be detected in an image recognition mode, the folding screen testing method can detect the crease, and simultaneously can utilize the detection device 700 to obtain the optical image of the screen of the folding screen mobile phone 1, and determine whether the liquid leakage phenomenon occurs on the screen of the folding screen mobile phone 1 through the image recognition method.

Then, under the condition that it is determined that no crease appears on the screen of the folding-screen mobile phone 1 and no liquid leakage appears on the screen of the folding-screen mobile phone 1, recording the folding times of the folding-screen mobile phone 1, continuing to perform the operation of unfolding and folding the folding-screen mobile phone 1 until the crease or liquid leakage appears on the screen of the folding-screen mobile phone 1 is detected, and recording the corresponding folding times when the crease or liquid leakage appears on the folding-screen mobile phone 1 as the folding times of the folding-screen mobile phone 1.

Similarly, finally, whether the folding times of the folding screen mobile phone 1 exceed a second threshold value is judged, and whether the folding screen mobile phone 1 meets the factory requirements is determined.

By the method, whether the screen of the folding screen mobile phone 1 has creases or leaks can be recognized more accurately, whether the screen of the folding screen mobile phone 1 has a liquid leakage phenomenon is determined by combining an image recognition method, the corresponding folding times when the screen of the folding screen mobile phone 1 has the creases or the liquid leakage phenomenon are recorded, the folding times of the folding screen mobile phone 1 are further determined more accurately, and then whether the folding screen mobile phone 1 meets the requirements or not is judged according to the folding times, so that the phenomenon that the creases or the liquid leakage phenomenon occur on the screen of the folding screen mobile phone 1 due to the fact that a user only uses the folding screen mobile phone for a plurality of times is avoided, and the user experience is influenced.

The test method of the folding screen provided by the application can be applied to any terminal equipment with a folding function, for example, foldable equipment provided with the folding screen. The terminal device may be a smart phone, a tablet computer, a wearable device, an on-board device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), and the like, and the specific type of the terminal device is not limited in this embodiment.

The following describes a method for testing the folding screen of the present application with reference to other drawings of the present application.

Fig. 9 shows a flow chart of a method for testing a folding screen according to the present application. It should be noted how to particularly describe, in each implementation of the present application, the main execution body of the method is the detection apparatus 700 shown in fig. 7, and more specifically, the main execution body may be the processing module 740 in the detection apparatus 700.

It should be noted that, for convenience of description, the following method is described as performing crease detection and leakage detection on the inner screen 20 of the folding-screen mobile phone 1 for convenience of description, but it should be understood that the method of the present application is also applicable to crease detection and leakage detection on the outer screen 10 of the folding-screen mobile phone 1, and is not described herein again.

As shown in fig. 9, the method includes:

901, obtaining the distance value from each point on the screen of the inner screen 20 to the detection device 700.

In some implementation manners, each point on the screen of the inner screen 20 may be each pixel point on the screen, may also be a detection area including a plurality of pixel points, and may also be an area for once detection of each laser sensor in the laser sensor lattice, which is not limited in this application. Correspondingly, when each point on the screen of the inner screen 20 is a pixel point on the screen, the distance from each point to the detection device 700 is the distance from each pixel point on the screen to the detection device 700. If each point on the screen of the inner screen 20 is a detection area including a plurality of pixels, the distance from each point to the detection device 700 should be the distance from the central pixel of the detection area to the detection device 700, or the average (or median) of the distances from each pixel in the detection area to the detection device 700, which is not limited in the present application.

Exemplarily, taking a detection area including several pixel points as an example, the inner screen 20 may be divided into j × k detection areas S3 as shown in fig. 10. In some implementations, the detection device 700 controls the ranging module 710 to start from the first detection region in the first row and the first column of fig. 10 and move along the path P until detecting the last detection region. In other implementations, since the crease generally appears at the rotation axis of the folding screen mobile phone 1 (e.g., 210 in fig. 2), the detection apparatus 700 may control the ranging module 710 to detect only the detection area near the rotation axis, for example, the detection areas of the second column to the third column every row. This is not limited by the present application.

For example, the distance from the detection device 700 to each detection area S3 of the above j × k detection areas S3 may be as shown in table 1 below:

table 1 distances of each detection area S3 from detection apparatus 700 in j × k detection areas S3

Detection area	Distance (unit: cm) of distance detecting means 700
		First detection area	10.0001
Second detection area	10.0002
		Third detection area	10.0005
Fourth detection area	9.0005
		Fifth detection area	10.0007
……	……
		(j × k) th detection region	9.0009

It should be understood that the present application is not limited to the above-mentioned distance value or unit of distance, that is, the unit of distance value or distance may be the above-mentioned centimeter, and may also be the unit of meter, millimeter, etc.

And 902, judging whether the number of points of which the difference between the distance value and the preset distance value exceeds a first threshold value is larger than a first preset number.

The preset distance value is actually the distance between the inner screen 20 of the folding-screen mobile phone 1 and the detection device 700 when there is no crease or liquid leakage. The preset distance value is a reference value for judging whether the screen 20 in the folding screen mobile phone 1 is folded or not. In some implementation manners, when the distance from the partial point in the inner screen 20 of the folding-screen mobile phone 1 to the detection device 700 is significantly greater than or less than the preset distance value, it indicates that the inner screen 20 of the folding-screen mobile phone 1 is uneven, that is, the inner screen 20 of the folding-screen mobile phone 1 is creased. That is, in some implementations, when the number of the differences between the distance values from the detection areas to the detection device 700 and the preset distance value exceeds the first threshold is greater than the first preset number, it can be indicated that the inner screen 20 of the folding-screen mobile phone 1 has a crease. It should be noted that the difference between the distance value and the preset distance value refers to an absolute value of the difference between the distance value and the preset distance value.

In some implementations, the preset distance value is an empirical value or an experimental value, and may be set according to a distance between the folding-screen mobile phone 1 and the detection device 700, for example, if the folding-screen mobile phone 1 is set in parallel with the detection device 700, the preset distance value is a distance between a plane where the detection device 700 is located and a plane where the inner screen 20 of the folding-screen mobile phone 1 is located. In other implementations, to eliminate the influence of the distance measurement error of the detection device 700 itself, the preset distance value may be a value that a difference between a plane where the detection device 700 is located and a plane where the inner screen 20 of the folding-screen mobile phone 1 is located satisfies a certain value. For example, assuming that the distance between the plane of the detecting device 700 and the plane of the inner screen 20 of the folding-screen mobile phone 1 is 10 cm, the preset distance may be a value range whose difference from the distance is less than 0.0001 cm, such as [ (10-0.0001), (10 + 0.0001)) ] cm. This is not limited by the present application.

In some implementations, the first threshold and the first preset number are both empirical values or experimental values, which is not limited in this application. For example, taking the distance value from each detection area to the detection device 700 in table 1 above as an example, assuming that the first threshold is 0.0004 cm, the preset distance value is 10, and the first preset number is 10, the difference between the distance value from each detection area to the detection device 700 and the preset distance value may be as shown in table 2 below:

TABLE 2 difference between the distance from each detection area to the detection device 700 and the predetermined distance

Based on the above table 2, if the number of the differences between the distance values from the detection areas to the detection device 700 and the preset distance values exceeds 0.0004 and does not exceed 10, it is determined that no crease appears in the folding screen mobile phone 1. Then the inner panel 20 continues to be checked for a liquid leakage. In some implementations, the detection device 700 will also record the number of folds of the folding-screen handset 1 at the same time.

903, if the number of points of which the difference between the distance value and the preset distance value exceeds the first threshold value is less than the first preset number, judging whether the inner screen 20 has a liquid leakage phenomenon.

In some implementations, the detection apparatus 700 may acquire a plurality of test images of the inner screen 20 in a flat state under different test conditions, and determine whether the inner screen 20 has a liquid leakage phenomenon by using a similarity between the test images and the reference images. In some implementations, the test conditions include a shooting angle at which the camera module 720 of the detection apparatus 700 shoots the inner screen 20 and/or an ambient light brightness of an environment in which the inner screen 20 is shot. That is, the detection apparatus 700 can obtain a plurality of test images in a flat state at different shooting angles and/or at the ambient light brightness of the environment where the inner screen 20 is shot. The reference image is an image corresponding to the inner screen 20 without a liquid leakage phenomenon, and it can be understood that the test image under each test condition corresponds to the reference image.

It is understood that the liquid leakage phenomenon generally occurs in the area where the crease occurs, and therefore, in some implementations, in order to reduce the error caused by the shooting angle and/or the brightness of the ambient light of the environment where the image is shot, the reference image may be an image corresponding to the area where the crease does not occur in the test image, that is, the reference image may be a part of the test image. This is not limited by the present application.

It is understood that, since the liquid leakage phenomenon is more obvious in the solid background, the test image and the reference image may be solid images of the inner screen 20, specifically, the tester may control the inner screen 20 to display solid white through a developer option, and then obtain the solid images of the inner screen 20 by using the camera module 720 of the detection apparatus 700, which is not limited in this application.

It will be appreciated that, as noted above, the leakage may cause the color displayed on the screen to be abnormal, and thus in some implementations, the similarity of the display parameters between the test image and the reference image may be compared to determine whether the leakage occurs on the inner screen 20. Specifically, the first display parameter of the test image under each test condition, including but not limited to display brightness, contrast, color coordinate, color temperature, color deviation, etc., may be obtained, then the first display parameter of the test image under each test condition is compared with the second display parameter of the corresponding reference image under the test condition, and according to the similarity between the first display parameter and the second display parameter, it is determined whether the inner screen 20 has a liquid leakage phenomenon, and if the similarity between the first display parameter and the second display parameter is smaller than the third threshold, it is determined that the inner screen 20 has a liquid leakage phenomenon.

In some implementations, whether the inner screen 20 has the liquid leakage phenomenon may be determined by extracting a first feature vector of the first display parameter and a second feature vector of the second display parameter, and comparing an euclidean distance, a cosine distance, a hamming distance, and the like between the two feature vectors. And if the vector distance between the two characteristic vectors is smaller than the vector distance threshold value, determining that the inner screen 20 has the liquid leakage phenomenon. This is not limited by the present application.

904, if the detection device 700 judges that the inner screen 20 has no liquid leakage, the folding times are increased by 1, and the folding test is performed again.

For example, if the detection apparatus 700 determines that no liquid leakage occurs in the inner screen 20 during the 90 th folding test, the detection apparatus 700 increases the number of folding times by 1, and performs the 91 st folding test after performing the "folding-unfolding" operation on the folding screen mobile phone 1.

That is, under the condition that neither the inner screen 20 has a crease nor a liquid leakage phenomenon, recording the current folding times of the folding-screen mobile phone 1, and continuing to perform crease detection and liquid leakage detection on the folding-screen mobile phone 1 until it is determined that the inner screen 20 has a crease or a liquid leakage phenomenon, and then taking the corresponding folding times when the inner screen 20 has a crease or a liquid leakage phenomenon as the folding times of the folding-screen mobile phone 1. Whether the folding screen mobile phone 1 meets the factory requirements or not is judged according to the determined folding times, the phenomenon that the folding screen mobile phone 1 is folded or leaked after the user uses the folding screen mobile phone for several times can be avoided, and user experience is improved.

In some implementations, for the method 902 described above, if the detection apparatus 700 determines that the number of points on the inner screen 20 whose difference between the distance from each point to the detection apparatus 700 and the preset distance value exceeds the first threshold value exceeds the first preset number, the following 905 is performed.

Or in other implementations, for the method 903 described above, if the detection apparatus 700 determines that the inner screen 20 of the folding-screen mobile phone 1 has a liquid leakage phenomenon, the following 905 is also performed. That is, the following 905 is performed when the detection device 700 determines that the inner panel 20 is creased or has a liquid leakage phenomenon.

905, recording the current folding times of the folding screen mobile phone 1 as the folding times of the folding screen mobile phone 1.

For example, if the detecting device 700 detects that the inner panel 20 is folded according to the above-mentioned methods 901 to 902 at the 90 th folding test, the detecting device 700 records the current folding times (90), and takes 90 as the folding times of the folding screen mobile phone 1.

For another example, if the detection device 700 detects that the inner panel 20 has a liquid leakage phenomenon according to the methods 901 to 903 in the 90 th folding test, the detection device 700 records the current folding times (90), and takes 90 as the folding times of the folding screen mobile phone 1.

In the method, whether the folding screen mobile phone 1 has the crease or not can be accurately determined by a distance detection method, and whether the folding screen mobile phone 1 has the liquid leakage or not is analyzed by combining an image analysis method, so that the folding times corresponding to the crease or the liquid leakage of the folding screen mobile phone 1, namely the folding times of the folding screen mobile phone 1, can be detected, and then whether the folding screen mobile phone 1 meets the factory requirements or not can be determined according to the comparison between the folding times and a second threshold corresponding to the factory requirements, thereby avoiding the situation that the crease or the liquid leakage occurs only by using the folding screen mobile phone 1 for a few times of a user, and improving the user experience.

It can be understood that, by the above method, the folding times corresponding to the crease only appearing and the folding times corresponding to the leakage only appearing may be detected, but the leakage and the crease may not appear simultaneously, for example, the crease does not appear after the leakage or the leakage does not appear after the crease appears, therefore, in some implementations of the present application, the detection may be performed for the crease and the leakage respectively, that is, the folding times corresponding to the crease appearing in the folding screen mobile phone 1 and the folding times corresponding to the leakage when the leakage appears are detected respectively, and then whether the folding times of the crease and the folding times corresponding to the leakage of the folding screen mobile phone 1 meet the factory requirements is determined respectively. It is to be understood that the specific detection method is the same as that described in the above methods 901 to 903, and reference may be made to the foregoing description, which is not repeated herein.

A schematic diagram of a hardware structure 1100 of the mobile phone 1 for implementing the method is described below with reference to fig. 11.

As shown in fig. 11, the mobile phone 1 may include a processor 110, an external memory interface 120, an internal memory 121, a Universal Serial Bus (USB) interface 130, a charging management module 140, a power management module 141, a battery 142, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a speaker 170A, a receiver 170B, a microphone 170C, a sensor module 180, a button 190, a display screen 194, and the like. The sensor module 180 may include a gyro sensor 180A, an acceleration sensor 180B, a touch sensor 180C, and the like.

It should be understood that the structure illustrated in the embodiment of the present invention does not specifically limit the mobile phone 1. In other embodiments of the present application, the handset 1 may include more or fewer components than shown, or combine certain components, or split certain components, or a different arrangement of components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

In some embodiments of the present application, the mobile phone 1 may be in communication connection with the detection apparatus 700 to receive a control instruction sent by the detection apparatus 700, so as to implement a corresponding operation. For example, when the detection device 700 obtains the test image of the inner screen 20 of the mobile phone 1 through the camera module 720, a tester may send a control instruction to the processor 110 of the mobile phone 1 through the detection device 700 to control the display screen (including the inner screen 20 and the outer screen 10) of the mobile phone 1 to perform pure color display, so that the camera module 720 obtains the pure color test image of the inner screen 20 of the mobile phone 1.

A memory may also be provided in the processor 110 of the handset 1 for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may hold instructions or data that have just been used or recycled by the processor 110. If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory. Avoiding repeated accesses reduces the latency of the processor 110, thereby increasing the efficiency of the system. In some implementations, the processor 110 may control the display screen of the mobile phone 1 to perform a solid color display according to the control instruction sent by the detection apparatus 700. In some embodiments, processor 110 may include one or more interfaces. The external memory interface 120 may be used to connect an external memory, such as a Micro SD card, to extend the storage capability of the mobile phone 1. The external memory communicates with the processor 110 through the external memory interface 120 to implement data storage functions.

The internal memory 121 may be used to store computer-executable program code, which includes instructions. The internal memory 121 may include a program storage area and a data storage area. The storage program area may store all or part of the program code corresponding to the method for determining the number of times of folding according to the present application, so that when the program code is executed, the mobile phone 1 can control the display screen of the mobile phone 1 to perform pure color display according to the control instruction of the detection device 700.

The wireless communication function of the mobile phone 1 can be realized by the antenna 1, the antenna 2, the mobile communication module 150, the wireless communication module 160, the modem processor, the baseband processor, and the like.

The

antennas

1 and 2 are used for transmitting and receiving electromagnetic wave signals. The mobile communication module 150 may provide a solution including wireless communication of 2G/3G/4G/5G and the like applied to the handset 1. The wireless communication module 160 may provide a solution for wireless communication applied to the mobile phone 1, including Wireless Local Area Networks (WLANs) (e.g., wireless fidelity (Wi-Fi) networks), bluetooth (blue tooth, BT), global Navigation Satellite System (GNSS), frequency Modulation (FM), near Field Communication (NFC), infrared (IR), and the like.

The gyro sensor 180A and the acceleration sensor 180B in the sensor module 180 of the mobile phone 1 are configured to obtain the unfolding angle of the inner screen 20, so as to determine the unfolding state of the inner screen 20 according to the unfolding angle of the inner screen 20.

In some embodiments, the cellular phone 1 may have a plurality of gyro sensors 180A and a plurality of acceleration sensors 180B, which are respectively provided on the outer screen 10 and the inner screen 20 of the cellular phone 1. For example, a set of sensors { a gyro sensor 180A and an acceleration sensor 180B } is provided on the external screen 10 of the mobile phone 1, and a set of sensors { a gyro sensor 180A and an acceleration sensor 180B } is also provided on the internal screen 20 of the mobile phone 1. Then, the mobile phone 1 determines the unfolding angle of the inner screen 20 of the mobile phone 1 by combining the data collected by the gyroscope sensor on the inner screen 10 and the data collected by the acceleration sensor.

The touch sensor 180C may be disposed on the display screen 194, and the touch sensor 180C and the display screen 194 form a touch screen, which is also called a "touch screen". In some embodiments, visual output related to touch operations may be provided through the display screen 194. In other embodiments, the touch sensor 180C may be disposed on the surface of the mobile phone 1, different from the position of the display 194. This is not limited by the present application.

The display screen 194 includes an inner screen 20 and an outer screen 10.
