[0002] A computer monitor is one of the output devices of a computer system, used to display graphics and text information generated by the computer. It is the main interface for users to interact with the computer, providing visual feedback on computer operations and data presentation. Types of monitors include liquid crystal displays (LCD), LED displays, organic light-emitting diode displays (OLED), cathode ray tube displays (CRT), etc. During the production process, manufacturers need to ensure that each monitor meets certain quality standards. Inspection can help identify defects in the manufacturing process and ensure that the monitor has consistent high quality when it leaves the factory.

[0003] After searching, the existing Chinese patent (Announcement No.: CN219225251U) discloses an automatic display defect detection device, which relates to the technical field of display defect detection devices, including a first base and a second base fixedly connected to one side of the first base, and a computer is installed on the upper surface of the second base. In the automatic display defect detection device, the staff starts the first servo motor to drive the bidirectional threaded rod to rotate, and then drives the two clamping blocks to clamp the display to be detected, and then the staff starts the detector through the controller, and then the staff starts the second servo motor, and then the second servo motor drives one of the screws, and then drives the other screw through two pulleys and a transmission belt, so that the two screws jointly drive the inverted C-row mounting table, and then the detector detects the display to be detected, thereby solving the problem that the traditional display defect detection device requires manual detection by the staff and the detection results are inaccurate.

[0004] In actual use of the above patent, the staff places the display to be tested on the surface of multiple rollers, and then starts the first servo motor, which then drives the bidirectional threaded rod, and then drives the assembly composed of a fixing member, a connecting block and a first slider, and then drives two clamping blocks to clamp the display to be tested. However, there are gradually more curved screens on the market. When clamping the curved screen, it is placed on the roller, and the curvature of the curved surface cannot fit with the roller, resulting in uneven force on the curved screen when clamping, which leads to stress concentration of the display, causing cracks or other damage. Therefore, a computer display detection device is proposed to address the above problems. Utility Model Content
