AI Technical Summary
Traditional display panel testing relies on manual operation and human observation, which is inefficient, lacks scientific rigor and unified standards, and makes it difficult to guarantee the accuracy of test results.
The system employs a worktable assembly, a lens assembly, and a pressing assembly working together to precisely capture images of the front and back of the display panel using movable first and second capture lenses. It then receives and displays data via a control panel, replacing human observation and manual operation.
It has achieved unified standards and scientific rigor in test results, reduced manpower and time costs, and significantly improved testing efficiency.
