[0002] LED screen is a new type of imaging electronic device made of light-emitting diodes arranged in sequence. Due to its high brightness, wide viewing angle and long life, it is widely used in products such as outdoor advertising screens. During the production process of LED screens, in order to prevent defective products from entering the market, it is necessary to use LED display production test and detection equipment to detect dark spots and bad pixels on the surface of the LED display to ensure the quality of the LED display.

[0003] After searching, the Chinese patent application number 201920762813.2 discloses a test and detection device for LED display production, whose structure includes a housing, an external power cord, a display screen, a switch button, a data connection line, a support device, a circuit board and a single-chip microcomputer. By setting a support device, the top left side of the support device is rotatably connected to the housing through a rotating shaft, and an adjustable telescopic rod is set at the bottom left end of the support device. By controlling the length of the adjustable telescopic rod, the top of the support device is rotated to adjust the angle of the support device, that is, the inclination angle of the display screen on the support device is adjusted, so that the user can observe the display screen vertically, and a fixing device is set on the support device, and the top of the display screen is fixed by the fixing device to avoid damage caused by the forward tilt of the display screen;

[0004] The above patent still has the following deficiencies: (1) It is not convenient to clean the surface of the LED display screen. During the production and processing of the LED display screen, some foreign matter, such as residual glue, plastic debris, and packaging paper debris, may adhere to the surface of the LED display screen. As a result, when the device detects the LED display screen, the foreign matter may block the surface of the LED display screen, causing abnormalities in the structure of the device detection;

[0005] (2) It is inconvenient to pick up the LED display screen. Since the device usually detects the LED display screen module, the glass or plastic material at the edge is easily squeezed and cracked or damaged, which may cause the screen to malfunction or performance degradation.

[0006] Therefore, there is an urgent need for a test and detection device for LED display production to solve the above problems. Utility Model Content
