Description

Technical Field

[0001] This application relates to the field of flexible display screen reliability testing technology, and in particular to a flexible display screen testing device and a flexible display screen testing method. Background Technology

[0002] With the development of technology, virtual shooting using flexible LED splicing screens is the latest trend in film and television production. LED screens are not only used as side wall backgrounds, but are now also being extended to ceiling and floor scenes, forming a multi-dimensional "air-sky-ground" combination solution. These solutions need to have characteristics such as high fidelity, wide viewing angle, small pitch, multi-dimensionality, treadability, curved and irregular shapes, and stability.

[0003] While current flexible LED video walls possess characteristics such as being able to be stepped on, bent, and twisted, their stress tolerance and bending range are limited. During use in film and television virtual shooting, they must withstand various stresses, including actors / objects stepping on them, squeezing, and bending / torsional deformation at joints / force-bearing points, posing challenges to the screen's mechanical reliability. To address the key technical requirements of current LED displays, the mechanical reliability testing of flexible LED displays needs to subject the screen to repeated impact, squeezing, bending, and twisting tests under various stresses to test its lifespan under prolonged stress. However, current testing equipment mainly performs tests on various stresses separately, resulting in lengthy and highly repeatable tests, and single-stress tests cannot assess the mechanical reliability under combined stress. Summary of the Invention

[0004] Therefore, it is necessary to provide a flexible display screen testing device and a flexible display screen testing method to address the above problems, which can improve the efficiency of reliability testing for flexible display screens.

[0005] A flexible display screen testing device includes: a fixed platform, wherein at least two fixed platforms are spaced apart, and all fixed platforms are used to fix the screen under test; a bending mechanism, wherein the bending mechanism includes a bending component and a first driving component, the bending component is connected between two adjacent fixed platforms, the first driving component is drivenly connected to the bending component, and the first driving component is used to drive the bending component to bend and deform; and an impact mechanism, wherein the impact mechanism includes an impact component and a second driving component, the second driving component is drivenly connected to the impact component, and the second driving component drives the impact component to move closer to or away from the fixed platforms.

[0006] In the aforementioned flexible display screen testing device, during operation, the device is initially positioned with all fixed platforms on the same plane. The screen under test is then fixed onto the fixed platforms, allowing it to deform in accordance with the deformation of the platforms. By setting the test parameters for the impact and bending mechanisms, the impact and bending mechanisms are sequentially activated. The second driving component drives the impact component to move towards or away from the fixed platforms, enabling it to impact the screen under test. This simulates various foot-stepping positions (middle of the screen, edge, etc.), different forces, and different gravity positions (multiple force points). The bending mechanism, driven by the first driving component, causes the bending component to bend, thereby bending the fixed platforms and the screen under test. This allows at least impact and bending tests to be completed on a single device, eliminating the need for repeated disassembly and replacement of testing instruments, thus improving the efficiency of flexible display screen reliability testing.

[0007] The technical solution will be further explained below:

[0008] In one embodiment, the flexible display testing apparatus further includes a torsion mechanism, which is drivenly connected to each of the fixed stages and is capable of driving two adjacent fixed stages to rotate relative to each other.

[0009] In one embodiment, the torsion mechanism includes a third driving member and an abutting member. The fixed platform is provided with a torsion shaft, and the axial direction of the torsion shaft is the same as the parallel direction of the plurality of fixed platforms. The third driving member is drivenly connected to the abutting member, and the abutting member is rotatably connected to the fixed platform. The third driving member is used to drive the abutting member to move so that the fixed platform rotates around the torsion shaft.

[0010] In one embodiment, there are at least two torsion mechanisms, and the torsion mechanisms are arranged in a one-to-one correspondence with the fixed platform.

[0011] In one embodiment, the bending angle between two adjacent fixed platforms ranges from 5° to 90°.

[0012] In one embodiment, the impact mechanism further includes a guide extending along a first direction, which is the same as the parallel direction of the plurality of fixed platforms. The impact member is movably disposed on the guide. The second driving member is used to drive the impact member to move along the first direction and a second direction, wherein the second direction intersects the first direction.

[0013] In one embodiment, the second driving component includes a walking module and an impact module. The walking module is driven to the impact component, and the walking module drives the impact component to move along the first direction. The impact module is driven to the impact component, and the impact module is used to drive the impact component to move along the second direction to impact the screen under test.

[0014] In one embodiment, the impact component includes a movable seat, a spring, and an impact part. The movable seat is connected to the impact part via the spring. The movable seat is guided and engaged with the guide member. The impact module is driven to the impact part. The spring provides impact force to the impact module through its own elastic deformation. The impact module is driven to the impact part. The walking module is driven to the movable seat.

[0015] In one embodiment, the flexible display screen testing device further includes a status monitoring component, which is electrically connected to the screen under test and is used to monitor the test parameters of the screen under test.

[0016] This application also provides a flexible display screen testing method, which employs the flexible display screen testing device described above and includes the following steps:

[0017] The flexible display screen testing device is initialized, with all fixed platforms located on the same plane;

[0018] The screen under test is fixed on at least two fixed platforms and electrically connected to the status monitoring device;

[0019] Set the test parameters for the impact mechanism, bending mechanism, and torsion mechanism;

[0020] The impact mechanism, bending mechanism, and torsion mechanism are activated. The status monitoring device monitors the test parameters of the screen under test and determines whether the test parameters are in a first state or a second state. If the test parameters are in the first state, the screen under test is normal, the currently set test parameters are recorded, and then the test parameters of the impact mechanism, bending mechanism, or torsion mechanism are changed to conduct the next round of testing. If the test parameters are in the second state, the screen under test is abnormal, the currently set test parameters are recorded, and the test ends. Attached Figure Description

[0031] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0032] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 A schematic diagram of the overall structure of a flexible display screen testing device 100 according to an embodiment of this application is shown. Figure 2 A schematic diagram of the initial state of the fixed platform 110 in one embodiment of this application is shown. Figure 3 It shows Figure 2 A schematic diagram of the bent state of the fixed platform 110. One embodiment of this application provides a flexible display screen testing device 100. The flexible display screen testing device 100 includes: a fixed platform 110, a bending mechanism 120, and an impact mechanism 130. At least two fixed platforms 110 are provided and spaced apart. All fixed platforms 110 are used to fix the screen under test. The bending mechanism 120 includes a bending member 121 and a first driving member 122. The bending member 121 is connected between two adjacent fixed platforms 110. The first driving member 122 is driven to the bending member 121 and is used to drive the bending member 121 to bend and deform. The impact mechanism 130 includes an impact member 131 and a second driving member 132. The second driving member 132 is driven to the impact member 131, and the second driving member 132 drives the impact member 131 to move closer to or away from the fixed platform 110.

[0033] In operation, the flexible display screen testing device 100 is initially positioned with all fixed platforms 110 on the same plane. The screen under test is then fixed onto the fixed platforms 110, allowing it to deform in response to the deformation of the fixed platforms 110. By setting the test parameters for the impact mechanism 130 and the bending mechanism 120, the impact mechanism 130 and the bending mechanism 120 are activated sequentially. The second driving member 132 drives the impact member 131 to move towards or away from the fixed platforms 110, enabling the impact member 131 to impact the screen under test. This simulates various stepping positions (middle of the screen, edge, etc.), different forces, and different gravity positions (multiple force points). The bending mechanism 120, through the first driving member 122, drives the bending member 121 to bend, thereby bending the fixed platforms 110 and the screen under test. In this way, at least impact tests and bending tests can be completed on the same device without repeated disassembly and replacement of testing instruments, which is beneficial to improving the efficiency of flexible display screen reliability testing.

[0034] Optionally, the screen under test can be fixed on the fixed platform 110 by adhesive bonding, snap-fitting, bolt connection, threaded connection, screw connection, crimping or other connection methods.

[0035] Specifically, please refer to Figure 1 The mounting platform 110 has at least two threaded holes. The screen under test is fixed to the mounting platform 110 by bolts. This ensures a stable connection, facilitates assembly and disassembly, and improves testing results and work efficiency.

[0036] It should be noted that this embodiment only provides a specific implementation of the fixed platform 110, but is not limited thereto.

[0037] There can be two or more fixed platforms 110, and one or more bending members 121. Two adjacent fixed platforms 110 are connected by bending members 121, and the angle of two adjacent fixed platforms 110 can be changed by bending deformation of bending members 121.

[0038] It should be noted that the driving connection between the second driving member 132 and the impact member 131 should be understood as the connection between the second driving member 132 and the impact member 131. The connection method can be a contact connection or a non-contact connection, and it can be a mechanical connection or an electrical connection. The second driving member 132 serves as a power source and can drive the impact member 131 to move closer to or away from the fixed platform 110.

[0039] Optionally, the bending member 121 can be a bending rod structure, a connecting rod structure, a gear structure, a turbine structure, or other structural forms.

[0040] In one embodiment, such as Figure 1 As shown, the impact mechanism 130 also includes a guide 133. The guide 133 extends along a first direction, which is the same as the parallel direction of the plurality of fixed platforms 110. The impact member 131 is movably disposed on the guide 133. A second drive member 132 is used to drive the impact member 131 to move along a first direction and a second direction, wherein the second direction intersects the first direction.

[0041] In order to further understand and explain the first and second directions, Figure 1 For example, the first direction is Figure 1 The direction pointed to by any arrow on S1 is the second direction. Figure 1 The direction pointed to by any arrow on S2.

[0042] Specifically, in this embodiment, the first direction is perpendicular to the second direction. For example, the first direction is horizontal and the second direction is vertical.

[0043] Optionally, the guide 133 can be a guide rail, guide post, guide groove, guide rod slide rail or other guide structure.

[0044] Specifically, please refer to Figure 1 The guide component 133 is a parallel guide rail. This results in a simple structure, easy installation, strong guiding performance, and high speed, which is beneficial for the automatic control of the impact component 131 by the second drive component 132.

[0045] It should be noted that this embodiment only provides a specific implementation of the guide member 133, but is not limited thereto.

[0046] Please see Figure 4 and Figure 5 , Figure 4 A schematic diagram of the torsion mechanism 140 in one embodiment of this application is shown. Figure 5 It shows Figure 2 A schematic diagram of the structure of the fixed platform 110 after twisting. In one embodiment, as shown... Figure 1 As shown, the flexible display screen testing apparatus 100 also includes a torsion mechanism 140. The torsion mechanism 140 is driven to each fixed stage 110, and the torsion mechanism 140 can drive two adjacent fixed stages 110 to twist relative to each other. Therefore, in this flexible display screen testing apparatus 100, torsion testing can also be performed simultaneously, by driving the fixed stages 110 to twist through the torsion mechanism 140, thereby causing the screen under test to twist.

[0047] Specifically, please refer to Figure 1 and Figure 4 The torsion mechanism 140 includes a third driving member 141 and an abutment member 142. The fixed platform 110 is provided with a torsion shaft 150, and the axial direction of the torsion shaft 150 is the same as the parallel direction of the multiple fixed platforms 110. The third driving member 141 is driven to the abutment member 142, and the abutment member 142 is rotatably connected to the fixed platform 110. The third driving member 141 drives the abutment member 142 to move, causing the fixed platform 110 to rotate around the torsion shaft 150. Thus, the third driving member 141 can drive each fixed platform 110 to rotate, thereby causing two adjacent fixed platforms 110 to twist relative to each other, and consequently causing the screen under test to twist, achieving torsion testing.

[0048] For further details, please refer to Figure 4 The fixed platform 110 is provided with a connecting part 123, and the contact member 142 is a telescopic rod, the extension and retraction direction of which is perpendicular to the axial direction of the torsion shaft 150. One end of the telescopic rod is rotatably connected to the connecting part 123. When the telescopic rod extends or retracts, the fixed platform 110 rotates around the torsion shaft 150. Thus, the telescopic rod is extended or retracted by the third driving member 141, thereby realizing the rotation of the fixed platform 110 around the torsion shaft 150. Furthermore, through the driving of the third driving member 141, the torsion range between adjacent fixed platforms 110 can be set and controlled according to the testing requirements of the screen under test, which is convenient, reliable, and conducive to ensuring the effect of the torsion test.

[0049] Optionally, the third drive unit 141 can be a motor, a cylinder, a hydraulic cylinder, or other drive methods.

[0050] Specifically, in this embodiment, the third driving component 141 is a motor. This facilitates control and makes maintenance convenient.

[0051] It should be noted that this embodiment only provides a specific implementation of the third driving component 141, but is not limited thereto.

[0052] In one embodiment, please refer to Figure 1 and Figure 4 There are at least two torsion mechanisms 140. Each torsion mechanism 140 corresponds one-to-one with the fixed platform 110. This allows for adjustment of the torsion position, enabling torsion at different locations on the screen being tested, thus improving work efficiency.

[0053] Specifically, in this embodiment, please refer to Figure 1 There are three fixed platforms 110, three torsion mechanisms 140, and two bending parts 121. The three fixed platforms 110 are respectively set up by two bending parts 121.

[0054] In one embodiment, the bending angle between two adjacent fixed platforms 110 ranges from 5° to 90°. Therefore, it can meet the testing requirements for different bending angles and is suitable for testing different flexible screen product models, thus improving testing results.

[0055] In one embodiment, the second driving component 132 includes a walking module and an impact module (not shown in the figure). The walking module is driven to the impact component 131, and drives the impact component 131 to move along a first direction. The impact module is driven to the impact component 131, and drives the impact component 131 to move along a second direction to impact the screen under test. In this way, the walking module and the impact module independently control the movement in two directions, which is beneficial to improving control efficiency and maintenance convenience.

[0056] In one embodiment, please refer to Figure 1 The impact element 131 includes a movable base 1311, a spring 1312, and an impact part 1313. The movable base 1311 is connected to the impact part 1313 via the spring 1312. The movable base 1311 is guided and engaged with a guide member 133. The impact module is connected to the movable base 1311 via the spring 1312, and the impact module is driven to the impact part 1313. The spring 1312 provides impact force to the impact module through its own elastic deformation, and the walking module is driven to the movable base 1311. For example, the walking module is an electric walking wheel. Therefore, the movable base 1311 can be controlled to move on the guide member 133, causing the impact part 1313 to move to a designated position. Specifically, the impact module is detachably connected to the impact part 1313. By setting a corresponding impact force, the spring 1312 is compressed to a predetermined length. When an impact test is performed, the impact module releases the impact part 1313, thereby causing the impact module to drive the impact part 1313 to impact.

[0057] Optionally, the detachable connection between the impact module and the impact part 1313 can be a hook-on, snap-on, electromagnetic attraction, or other detachable connection methods.

[0058] Specifically, the impact module is an electromagnet (not shown in the figure). The impact module is magnetically engaged with the impact part 1313. Therefore, the release and magnetic attraction states of the impact module are realized by switching the electrical circuit of the impact module on and off, which facilitates automatic control and provides high stability.

[0059] It should be noted that this embodiment only provides a specific implementation of the impact module and the impact part 1313, but is not limited thereto.

[0060] In one embodiment, please refer to Figure 1 The flexible display screen testing device 100 also includes a status monitoring component 160. The status monitoring component 160 is electrically connected to the screen under test and is used to monitor the measured parameters of the screen. Specifically, if the measured parameter is in a first state, it indicates that the screen under test is normal; if the measured parameter is in a second state, it indicates that the screen under test is abnormal. Therefore, the status monitoring component 160 can monitor whether the screen under test is still in a normal state during reliability testing, which helps to improve testing efficiency.

[0061] Optionally, the measured parameter monitored by the status monitoring device 160 can be current, voltage, image brightness, screen display content, screen brightness, or other parameters.

[0062] For example, in one embodiment, the measured parameter is the brightness of the screen under test, with a first state of brightness greater than 0 and a second state of brightness less than 0. Thus, the status monitoring device 160 monitors the brightness of the screen under test in real time. If the display screen fails to light up during the test, it indicates a malfunction, and the current test parameters are recorded, and the test is stopped.

[0063] Alternatively, in another embodiment, the measured parameter is the current of the screen under test, with a first state where the current is greater than 0A and a second state where the current is equal to 0A. In this way, the status monitoring device 160 monitors the current status of the screen under test in real time. If the current is 0 during the test, it indicates an abnormal operation, and the current test parameter is recorded, and the test is stopped.

[0064] like Figure 1 As shown, one embodiment of this application also provides a method for testing flexible displays. The method for testing flexible displays uses the flexible display testing apparatus 100 described above and includes the following steps:

[0065] S10: The flexible display screen testing device 100 is initialized, and all fixed platforms 110 are located on the same plane;

[0066] S20: The screen under test is fixed on at least two fixed platforms 110 and electrically connected to the status monitoring device 160;

[0067] S30: Set the test parameters for impact mechanism 130, bending mechanism 120, and torsion mechanism 140;

[0068] S40: Start the impact mechanism 130, bending mechanism 120 and torsion mechanism 140, monitor the test parameters of the screen under test through the status monitoring device 160, and determine whether the test parameters are in the first state or the second state; if the test parameters are in the first state, the screen under test is normal, record the currently set test parameters, and then change the test parameters of the impact mechanism 130 or bending mechanism 120 or torsion mechanism 140 to conduct the next round of testing; if the test parameters are in the second state, the screen under test is abnormal, record the currently set test parameters, and end the test.

[0069] For example, after the flexible display screen testing device 100 is initialized and the screen under test is fixed on at least two fixed platforms 110, the test parameters for the impact mechanism 130, bending mechanism 120, and torsion mechanism 140 are set for the first time. Then, the test is started to activate the impact mechanism 130, bending mechanism 120, or torsion mechanism 140. If the test parameter monitored by the status monitoring device 160 is in the first state, the first set test parameters are recorded. Then, the test parameters are changed, i.e., the test parameters for the impact mechanism 130, bending mechanism 120, and torsion mechanism 140 are set for the second time, and this process is repeated. If the test parameter monitored by the status monitoring device 160 is in the second state, it indicates that the screen under test is abnormal. The first set test parameters are recorded, and the test ends.

[0070] The aforementioned flexible display screen testing method comprehensively considers mechanical performance reliability tests such as impact, bending, and torsion, simulating the trampling, folding, and deformation conditions experienced by flexible screens during daily use. It can also quantify and control the stress during impact, bending, and torsion, achieving reliability performance testing under certain stress conditions. This method is suitable for virtual LED screen testing, eliminating the need for repeated disassembly and replacement of testing instruments, thus improving the efficiency of flexible display screen reliability testing. The status monitoring component 160 can monitor the testing process in real time, improving the convenience of the testing process and the accuracy of the test results.
