Description

Technical Field

[0001] This application relates to the technical field, and in particular to a display screen defect detection device and detection method. Background Technology

[0002] With the development of display technology, people have higher and higher requirements for the functionality of display devices. As a result, more and more different types and forms of display screens are being used, such as notch screens, punch-hole screens, curved screens, and foldable screens.

[0003] During the manufacturing process of these displays, the inventors discovered through long-term research that there was a problem where cracks on the display surface were not detected in time, leading to the displays flowing into the next manufacturing process or even into the hands of customers, which greatly affected product quality and increased production costs. Summary of the Invention

[0004] Therefore, it is necessary to provide a display screen defect detection device and detection method to address the problem that if surface cracks of the display screen are not detected in time, the display screen will flow into the next production process or even into the hands of customers, which will greatly affect product quality and increase production costs.

[0005] According to one aspect of this application, an embodiment of this application provides a display screen defect detection device, comprising: a fixture having a receiving cavity; a fixing component for fixing the display screen, the fixing component being disposed within the receiving cavity and movably connected to the fixture; and an excitation component disposed within the receiving cavity and used to emit an ion beam to bombard the display screen to excite residual stress on the display screen.

[0006] The aforementioned display screen defect detection device uses an excitation component to emit an ion beam to bombard the display screen. Since the display screen is fixed to a fixing component, which is movably connected to a fixture within a receiving cavity, the display screen vibrates relative to the fixture along with the fixing component after being bombarded by the ion beam. This process excites and releases residual stress on the display screen, allowing any potential cracks to appear earlier. This enables the timely detection of displays with structural defects, preventing them from proceeding to the next manufacturing process, improving product quality, and reducing production costs. Simultaneously, ion beam bombardment of the display screen can also remove adhering substances from the screen surface, improving the flatness and hardness of the screen and enhancing its surface performance.

[0007] In one embodiment, the fixing assembly includes two opposing contoured platforms, each movably connected to a fixture. One contoured platform has an adhesive surface adapted to the surface of the display screen, and the other contoured platform has a bearing surface opposite the adhesive surface and adapted to the surface of the display screen. Fixing the display screen using this fixing assembly with two contoured platforms is applicable to various types, shapes, and sizes of displays, offering a wide range of applications. The adhesive surface on one contoured platform can bond to one surface of the display screen, ensuring a firm fixation, while the bearing surface on the other contoured platform can support the other surface of the display screen, resulting in more even stress distribution on the display screen.

[0008] In one embodiment, the fixing assembly further includes at least two elastic elements, each of which is movably connected to the fixture via an elastic element. The elastic elements are configured to provide a spring force that tends to move the contoured stage toward or away from the connection point between the elastic element and the fixture. This design allows the display screen and the contoured stage to vibrate relative to the fixture in response to the vibration of the elastic elements, providing a high degree of freedom in vibration. Furthermore, because the elastic elements provide a spring force that tends to move the two contoured stages toward or away from their connection points with the fixture, the display screen and the contoured stage can return to their pre-vibration positions after vibration ends, facilitating the next inspection.

[0009] In one embodiment, the excitation assembly includes a first ion beam emitter and a second ion beam emitter; the first ion beam emitter is located on the side of the adhesive surface facing away from the bearing surface, and the second ion beam emitter is located on the side of the bearing surface facing away from the adhesive surface. This design allows the first and second ion beam emitters to emit ion beams at two opposite surfaces of the display screen, respectively, so that the two opposite surfaces of the display screen are simultaneously bombarded by ion beams, thereby fully releasing the residual stress on the display screen.

[0010] In one embodiment, the display screen has a flat portion and a curved portion connected to the flat portion; a first ion beam emitter and / or a second ion beam emitter are disposed toward the curved portion. Compared to the flat portion, the stress concentration effect at the curved portion of the display screen is more pronounced. By adjusting the position of the first ion beam emitter and / or the second ion beam emitter to be disposed toward the curved portion, the ion beam is concentrated to bombard the curved portion, thereby stimulating the residual stress at the curved portion and releasing it as quickly as possible.

[0011] In one embodiment, the display screen defect detection device further includes a vision inspection mechanism disposed within the receiving cavity. The vision inspection mechanism is used to capture image information of the display screen and detect whether structural defects exist on the display screen based on the image information. This design enables automatic detection of structural defects by means of the vision inspection mechanism, improving the automation level of the display screen defect detection device and also increasing the detection efficiency of the display screen.

[0012] In one embodiment, the visual inspection mechanism includes a camera module and a processor. The camera module is positioned facing the display screen and is used to capture image information of the display screen. The processor is electrically connected to the camera module to acquire image information and detects whether there are structural defects on the display screen based on the image information. By capturing image information of the display screen with the camera module and identifying the structural defect information in the image information with the help of the processor, the structure is simple and easy to use.

[0013] In one embodiment, the display defect detection device further includes a heater and a humidifier disposed within the receiving cavity. By placing the heater and humidifier within the receiving cavity, the temperature and humidity within the receiving cavity can be adjusted, accelerating the appearance of any cracks that may exist on the display screen, thereby improving the detection efficiency of the display defect detection device. At the same time, adjusting the temperature and humidity within the receiving cavity can also detect moisture intrusion problems on the display screen.

[0014] According to another aspect of this application, an embodiment of this application provides a display screen defect detection method, applied to the display screen defect detection device as described above. The detection method includes: fixing the display screen to a fixing component; using an excitation component to emit an ion beam to bombard the display screen; and detecting whether there are structural defects on the display screen.

[0015] The aforementioned display screen defect detection method uses an excitation component in the detection device to bombard the display screen with an ion beam. After being bombarded by the ion beam, the display screen vibrates relative to the fixture along with the fixing component. This process excites and releases residual stress on the display screen, allowing any potential cracks to appear earlier. This enables the timely detection of displays with structural defects, preventing them from entering the next manufacturing process, improving product quality, and reducing production costs. Simultaneously, ion beam bombardment of the display screen can also remove adhering substances from the screen surface, improving the flatness and hardness of the screen and enhancing its surface performance.

[0016] In one embodiment, before bombarding the display screen with an ion beam emitted by the excitation component, the detection method further includes: setting the temperature inside the containment cavity to between 50°C and 60°C; and / or setting the humidity inside the containment cavity to between 65% and 85%. By setting the temperature and humidity inside the containment cavity to the above ranges, cracks that may exist on the display screen can be made to appear more quickly, improving the detection efficiency of the display screen defect detection device, and also enabling the detection of moisture intrusion problems on the display screen.

[0034] The inventors discovered through long-term research that in the manufacturing process of display screens, surface cracks are often not detected in time, leading to screens being passed on to the next production stage or even reaching customers. This significantly impacts product quality and increases production costs. However, surface cracks are difficult to detect using conventional testing equipment and methods.

[0035] Figure 1 This is a perspective view of the overall structure of a display screen defect detection device 10 provided in one embodiment of this application. Figure 2 This is a schematic diagram of the structure of a display screen 20 applicable to a display screen defect detection device 10 provided in one embodiment of this application.

[0036] To at least partially resolve the above issues, please refer to Figures 1 to 2 This application provides a display screen defect detection device 10, which includes a fixture 100, a fixing component 200 and an excitation component 300. The fixture 100 has a receiving cavity 110. The fixing component 200 is used to fix the display screen 20. The fixing component 200 is disposed in the receiving cavity 110 and is movably connected to the fixture 100. The excitation component 300 is disposed in the receiving cavity 110 and is used to emit an ion beam to bombard the display screen 20 to excite the residual stress on the display screen 20.

[0037] The display screen defect detection device 10 of this application embodiment can be applied to various types of display screens 20, such as liquid crystal display screens 20 (LCD), light-emitting diode (LED) display screens 20, organic light-emitting diode (OLED) display screens 20, etc. It can also be applied to display screens 20 of various shapes, such as notch screens, punch-hole screens, curved screens, foldable screens, etc., and can also be applied to display screens 20 of various shapes and sizes.

[0038] Specifically, the fixture 100 and the receiving cavity 110 within the display defect detection device 10 are used to fix and accommodate the fixing component 200, the excitation component 300, and the display screen 20, and to isolate them from the outside world to create a relatively stable detection environment. The material and size of the fixture 100 are not limited. For example, an aluminum alloy cube-shaped fixture 100 can be made, and a receiving cavity 110 with a length, width, and height of 600mm, 500mm, and 600mm respectively can be machined within it.

[0039] The fixing component 200 is disposed within the receiving cavity 110 and is movably connected to the fixture 100. This means that the fixing component 200 can move relative to the fixture 100, and their specific connection method is not limited. The fixing component 200 is used to fix the display screen 20. The method in which the display screen 20 is fixed to the fixing component 200 is not limited. For example, the fixing component 200 can clamp and fix the display screen 20, or it can be bonded and fixed to the display screen 20 with adhesive material. When the display screen 20 is fixed to the fixing component 200, both can move together relative to the fixture 100.

[0040] The excitation component 300 can emit an ion beam, which is a group of ions moving in almost the same direction at approximately the same speed. When the excitation component 300 emits an ion beam towards the display screen 20, the display screen 20 vibrates relative to the fixture 100 along with the fixing component 200 under the bombardment of the ion beam. This process can excite the residual stress on the display screen 20 and release it. Any cracks that may exist on the display screen 20 will appear in advance, thereby enabling timely detection of the display screen 20 with structural defects.

[0041] The display screen defect detection device 10 of this application embodiment uses an excitation component 300 to emit an ion beam to bombard the display screen 20. Since the display screen 20 is fixed to the fixing component 200, and the fixing component 200 is movably connected to the fixture 100 within the receiving cavity 110, the display screen 20, after being bombarded by the ion beam, can vibrate relative to the fixture 100 along with the fixing component 200. This process can excite and release residual stress on the display screen 20, causing any cracks that may exist on the display screen 20 to appear earlier. This allows for timely detection of display screens 20 with structural defects, preventing them from entering the next manufacturing process, improving product quality, and reducing production costs. Simultaneously, bombarding the display screen 20 with the ion beam can also remove deposits from the screen surface, improving the flatness and hardness of the screen and enhancing the surface performance of the display screen 20.

[0042] The method by which the display screen 20 is fixed to the fixing component 200 is not limited. In some embodiments, the fixing component 200 includes two oppositely arranged contouring platforms 210, which are movably connected to the fixture 100 respectively. One contouring platform 210 is provided with an adhesive surface 211 adapted to the surface of the display screen 20, and the other contouring platform 210 is provided with a bearing surface 212 that is opposite to the adhesive surface 211 and adapted to the surface of the display screen 20.

[0043] like Figure 1 As shown, the contouring platform 210 can adapt to the surface of the display screen 20 for better fixation. The contouring platform 210 can be made of materials such as silicone. Silicone is non-toxic, odorless, and colorless, and has high toughness and elasticity. Using silicone to make the contouring platform 210 can achieve a good fixation effect without scratching the display screen 20. The display screen 200 is fixed by a fixing component 200 including two contouring platforms 210, which can be applied to various types, shapes and sizes of display screens 20, and has a wide range of applications. The adhesive surface 211 on one contouring platform 210 can bond to one surface of the display screen 20, fixing the display screen 20 firmly, while the bearing surface 212 on the other contouring platform 210 can support the other surface of the display screen 20, making the force on the display screen 20 more even. In use, the two contouring platforms 210 can be separated first. After one surface of the display screen 20 is bonded to the bonding surface 211, the other contouring platform 210 can be moved so that the bearing surface 212 comes into contact with the other surface of the display screen 20 to fix the display screen 20.

[0044] After the two contoured stages 210 are aligned and clamp the display screen 20, the excitation component 300 emits an ion beam to bombard the display screen 20, causing it to vibrate relative to the fixture 100 along with the fixing component 200, thereby stimulating residual stress on the display screen 20. It should be noted that during this process, the movement of the display screen 20 relative to the fixture 100 with the fixing component 200 is relatively small, and will not cause the display screen 20 to detach from the fixing component 200.

[0045] The fixing component 200 is movably connected to the fixture 100. The specific connection method is not limited. In some embodiments, the fixing component 200 also includes at least two elastic elements 220. Two contouring stages 210 are movably connected to the fixture 100 by means of the elastic elements 220. The elastic elements 220 are configured to provide elastic force that causes the contouring stages 210 to have a tendency to move toward or away from the connection between the elastic element 220 and the fixture 100.

[0046] The elastic element 220 can be a spring, and there can be two or more of them. Both ends of the elastic element 220 are connected to the contouring platform 210 and the fixture 100, respectively, allowing the contouring platform 210 to move relative to the fixture 100 within a certain range. This design allows the display screen 20 and the contouring platform 210 to vibrate relative to the fixture 100 with the vibration of the elastic element 220, providing a large degree of freedom in vibration. Furthermore, because the elastic element 220 provides the contouring platform 210 with the ability to move closer to or further away from its connection point with the fixture 100... The elastic force of the elastic element 220, when compressed, causes the contouring stage 210 to tend to move away from its connection with the fixture 100. When stretched, the elastic force of the elastic element 220 causes the contouring stage 210 to tend to move closer to its connection with the fixture 100. Therefore, after the vibration ends, the display screen 20 and the contouring stage 210 can return to their positions before the vibration, facilitating the next test.

[0047] In order to bombard the display screen 20 more comprehensively and over a wider area, in some embodiments, the excitation component 300 includes a first ion beam emitter 310 and a second ion beam emitter 320; the first ion beam emitter 310 is disposed on the side of the adhesive surface 211 away from the bearing surface 212, and the second ion beam emitter 320 is disposed on the side of the bearing surface 212 away from the adhesive surface 211.

[0048] Please continue reading. Figure 1 Since the first ion beam emitter 310 is located on the side of the bonding surface 211 facing away from the supporting surface 212, the ion beam emitted by the first ion beam emitter 310 can bombard the surface of the display screen 20 connected to the bonding surface 211. Similarly, since the second ion beam emitter 320 is located on the side of the supporting surface 212 facing away from the bonding surface 211, the ion beam emitted by the second ion beam emitter 320 can bombard the surface of the display screen 20 connected to the supporting surface 212. This design allows the first ion beam emitter 310 and the second ion beam emitter 320 to emit ion beams to two opposite surfaces of the display screen 20, ensuring that both opposite surfaces are simultaneously bombarded by the ion beams, thus fully releasing residual stress on the display screen 20. It should be noted that, to avoid obstructing the ion beam, a channel (not shown in the figure) can be created on the contour stage 210 along the path of the ion beam.

[0049] Please refer to Figures 1 to 2 In some embodiments, the display screen 20 has a flat portion 21 and a curved portion 22 connected to the flat portion 21; a first ion beam emitter 310 and / or a second ion beam emitter 320 are disposed toward the curved portion 22.

[0050] The display screen 20 has a flat portion 21 and a curved portion 22 connected to the flat portion 21. It should be understood that the curved portion 22 can be located on one side of the flat portion 21. The mobile terminal device having this display screen 20 has a front display area and a side display area, and the curved portion 22, located on one side of the flat portion 21, can form the defining outline of the side display area of ​​the mobile terminal device. The number of curved portions 22 can also be multiple, and the specific number can be flexibly set according to different usage requirements. It is not limited here, and multiple curved portions 22 can be respectively arranged on different sides of the flat portion 21.

[0051] Compared to the straight section 21, the stress concentration effect at the curved section 22 of the display screen 20 is more obvious. By adjusting the position of the first ion beam emitter 310 and / or the second ion beam emitter 320 so that they are positioned toward the curved section 22, the ion beam is concentrated on bombarding the curved section 22, thereby stimulating the residual stress at the curved section 22 and releasing it as soon as possible.

[0052] Using the display screen defect detection device 10 of this application embodiment to excite the residual stress on the display screen 20 and release it, any cracks that may exist on the display screen 20 will appear in advance. In some embodiments, the presence of cracks on the display screen 20 can be determined by visual inspection by an inspector.

[0053] In other embodiments, the display screen defect detection device 10 further includes a visual inspection mechanism 400 disposed in the receiving cavity 110. The visual inspection mechanism 400 is used to capture image information of the display screen 20 and detect whether there are structural defects on the display screen 20 based on the image information.

[0054] Image information can be pictures or videos. In pictures or videos, the cracked areas on the display screen 20 will be clearly distinguished from the normal areas on the display screen 20 due to the presence of cracks. At this time, a detection device with analysis and detection functions can be used to detect the cracks. This design can achieve automatic detection of structural defects with the help of the vision inspection mechanism 400, improve the automation level of the display screen defect detection device 10, and also improve the detection efficiency of the display screen 20.

[0055] The visual inspection mechanism 400 detects whether there are structural defects on the display screen 20 based on the image information of the display screen 20. Specifically, in some embodiments, the visual inspection mechanism 400 includes a camera module 410 and a processor. The camera module 410 is positioned facing the display screen 20 and is used to capture image information of the display screen 20. The processor is electrically connected to the camera module 410 to obtain image information and detects whether there are structural defects on the display screen 20 based on the image information.

[0056] The camera module 410 captures image information from the display screen 20, and the processor identifies this image information to detect structural defects. The structure is simple and easy to use. It should be noted that, to facilitate the camera module 410's imaging, the contour stage 210 can have a receiving slot to accommodate the camera module 410, which is positioned within the receiving slot to directly image the display screen 20. Simultaneously, the visual inspection mechanism 400 may also include a light source 420 to provide more sufficient light to the camera module 410, achieving better imaging results.

[0057] In some embodiments, the display defect detection device 10 further includes a heater (not shown) and a humidifier (not shown) disposed within the receiving cavity 110.

[0058] Because the display screen 20 is more prone to aging in relatively high temperature and high humidity environments, meaning that cracks on it are more easily triggered, by installing a heater and a humidifier in the housing cavity 110, the temperature and humidity inside the housing cavity 110 can be adjusted to accelerate the appearance of any cracks that may exist on the display screen 20, thereby achieving aging modification of the display screen 20 and improving the detection efficiency of the display screen defect detection device 10. At the same time, after adjusting the temperature and humidity inside the housing cavity 110, the problem of moisture intrusion on the display screen 20 can also be detected.

[0059] Figure 3 A flowchart of a defect detection method for a display screen 20 provided in one embodiment of this application.

[0060] Please combine Figure 1 , Figure 2 And see Figure 3 This application provides a display screen defect detection method, applied to the display screen defect detection device 10 as described above. The detection method includes:

[0061] S102. Fix the display screen 20 to the fixing component 200;

[0062] S104. Use the excitation component 300 to emit an ion beam to bombard the display screen 20;

[0063] S106. Detect whether there are structural defects on the display screen 20.

[0064] The way the display screen 20 is fixed to the fixing component 200 is not limited. When the excitation component 300 emits an ion beam to the display screen 20, under the bombardment of the ion beam, the display screen 20 vibrates relative to the fixture 100 along with the fixing component 200. This process can excite the residual stress on the display screen 20 and release it. Cracks that may exist on the display screen 20 will appear in advance. At this time, it can be determined whether there are cracks on the display screen 20 by visual observation by the inspector, or other auxiliary equipment can be used to assist in the judgment.

[0065] The display screen defect detection method of this application embodiment uses an excitation component 300 in the detection device to emit an ion beam to bombard the display screen 20. After being bombarded by the ion beam, the display screen 20 vibrates relative to the fixture 100 along with the fixing component 200. This process can excite and release residual stress on the display screen 20, allowing any cracks that may exist on the display screen 20 to appear in advance. This enables timely detection of display screens 20 with structural defects, preventing them from entering the next manufacturing process, improving product quality, and reducing production costs. At the same time, bombarding the display screen 20 with the ion beam can also remove adhering substances from the screen surface, improve the flatness and hardness of the screen, and enhance the surface performance of the display screen 20.

[0066] As mentioned above, the display screen 20 is more prone to aging in relatively high temperature and high humidity environments, meaning that cracks on it are more easily induced. Therefore, in some embodiments, the detection method further includes the following steps before bombarding the display screen 20 with an ion beam emitted by the excitation component 300:

[0067] S103. Set the temperature inside the receiving cavity 110 to between 50°C and 60°C; and / or set the humidity inside the receiving cavity 110 to between 65% and 85%.

[0068] The temperature inside the receiving cavity 110 can be set between 50°C and 60°C. For example, the specific temperature value inside the receiving cavity 110 can be 50°C, 52°C, 55°C, 58°C, or 60°C, etc. These temperature values ​​are merely examples; in actual embodiments, the temperature value inside the receiving cavity 110 is not limited to these values. Alternatively, the humidity inside the receiving cavity 110 can be set between 65% and 85%. The specific humidity value inside the receiving cavity 110 can be 65%, 67%, 70%, 78%, 80%, or 85%, etc. These humidity values ​​are merely examples; in actual embodiments, the humidity value inside the receiving cavity 110 is not limited to these values. Alternatively, the temperature inside the containment cavity 110 can be set between 50°C and 60°C and the humidity between 65% and 85%. By setting the temperature and humidity inside the containment cavity 110 to the above range, cracks that may exist on the display screen 20 can be made to appear more quickly, thereby achieving aging modification of the display screen 20, improving the detection efficiency of the display screen defect detection device 10, and also detecting moisture intrusion problems on the display screen 20.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
