AI Technical Summary
Technical Problem
Existing projection quality testing methods require lighting up a large number of LED beads, which leads to overheating and energy loss in the Micro LED display panel, affecting testing accuracy and reliability.
Method used
By setting multiple detection positions and detection sequences on the display panel, pixel units of a set size are gradually illuminated, and projected images are acquired to obtain projection quality detection results, thereby reducing the number of LED beads that need to be lit.
Benefits of technology
This reduces the wear and tear on Micro LED display panels during the testing process, solves the problem of inaccurate test data caused by overheating, and improves testing accuracy and reliability.
