Technical Field

[0001] This invention relates to the field of display screen performance testing technology, specifically to an automotive display screen performance testing system. Background Technology

[0002] The car's display screen, located on the center console, serves as the multimedia and control center. It enables functions such as viewing navigation maps, playing music and videos, connecting via Bluetooth, and adjusting vehicle settings (e.g., air conditioning, lights). Some high-end models also support voice control, gesture operation, and even smartphone connectivity.

[0003] In the prior art, patent number CN112595862B, entitled "A Fully Automated Intelligent Aging Test Production Line for Mini LED Displays," includes: a feeding device for mounting multiple Mini LED displays onto a product fixture; a testing device located on one side of a transmission device for testing the multiple Mini LED displays transported by the transmission device; a lifting device connected to the testing device for transporting the product fixture carrying the tested Mini LED displays to the aging device; and an aging device connected to the lifting device for aging the Mini LED displays on the product fixture. This method reduces labor costs and improves production efficiency.

[0004] However, existing automotive displays require manual connection of cables to the display during testing, and the display is then tested by a testing system. Manual connection is inefficient and cannot be precise, which can damage the interface. Summary of the Invention

After the baffle 32 moves, it pulls the abutment plate 30 via the elastic rope 31, causing the abutment plate 30 to swing along the rotating shaft 26. The abutment plate 30 no longer obstructs the end of the display screen 2. The moving plate 13 continues to move, allowing the insertion plate 15 to be inserted into both ends of the display screen 2, further limiting the display screen 2. The telescopic plate 10 can then be inserted into the interior of the L-shaped plate 11. The rubber strip 22 on the surface of the moving plate 13 presses against the surface of the display screen 2.
