[0024] The utility model provides, for example Figure 1-4The MicroLED display performance testing device shown includes a main body 1. A gear groove 10 is provided at the lower end of the main body 1. A square extension rod 5 is installed at the lower end of the main body 1 through the gear groove 10. The square extension rod 5 is engaged with the gear shaft 11 fixed at the upper end and is locked inside the gear groove 10. Multiple arc-shaped buckles 6 are provided at the left and right ends of the square extension rod 5, and a stainless steel spring 8 is fixed at the inner end face of the arc-shaped buckles 6. A handle 4 is installed at the lower end of the main body 1 through the square extension rod 5. A square groove 15 is provided at the upper inner end of the handle 4. Arc-shaped grooves 9 are provided at the upper left and right sides of the inner wall of the square groove 15. An anti-slip groove 12 is provided at the outer wall of the handle 4.

[0025] The main unit 1 points the lens 7 at the MicroLED display screen. The lens 7 captures the infrared thermal radiation emitted by the MicroLED display screen when it is in operation. The infrared sensor inside the main unit 1 converts the infrared radiation captured by the lens 7 into an electrical signal, and the data is analyzed and processed by the built-in signal processing unit. The main unit 1 generates a thermal image of the display screen. Subtle differences in the surface temperature of the display screen are presented in the form of different colors or brightness. By observing the thermal image on the display screen, testers can quickly identify the temperature distribution of the MicroLED display screen, including hot spots, cold spots, or areas with uneven temperature.

[0026] like Figure 1 and Figure 3 As shown, a protective film 2 for the display screen is affixed to the front end of the main body 1. A through hole 14 is provided at the upper front end of the main body 1. Multiple front buttons 3 are provided at the lower front end of the main body 1. The control method of the front buttons 3 is set as a press type. A lens 7 is provided at the upper rear end of the main body 1. A rear button 13 is provided at the lower rear end of the main body 1. A square extension rod 5 is engaged in the inner position of a square groove 15. The handle 4 can be rotated through the square extension rod 5. When the square extension rod 5 rotates, it is centered on the gear shaft 11. The gear shaft 11 rotates in the inner position of the gear groove 10. The main body 1 can be extended between the square extension rod 5 and the handle 4. The arc-shaped buckle 6 can be retracted into the inner position of the square extension rod 5 when squeezed. The arc-shaped buckle 6 can be engaged in the inner position of the arc-shaped groove 9 under the elastic action of the stainless steel spring 8.

[0027] The main unit 1 analyzes the heat dissipation effect of the MicroLED display under different brightness or workloads to determine whether the heat dissipation design is reasonable. If the temperature in some areas rises abnormally, it may indicate a short circuit, pixel failure or other faults. The thermal imager can quickly locate the problem area. The main unit 1 can detect the uniformity of the surface temperature of the display to ensure that the heat distribution of all pixels is consistent during operation and avoid local overheating or uneven light emission.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
