AI Technical Summary

⚠Technical Problem

In existing technologies, independent testing of photosensitive elements and screen components is inefficient, cannot simulate the lighting conditions of actual use scenarios, and lacks pre-assembly testing tools, resulting in calibration errors and material waste.

⚗Method used

An in-screen light-sensing testing system was designed. The system uses a box made of black light-absorbing material, with an internal workbench and an adjustable brightness LED light source. Combined with a light source adjustment mechanism and controller, it simulates real ambient lighting and is integrated into the display production line for pre-testing of light-sensing components.

🎯Benefits of technology

It achieves efficient and accurate calibration of photosensitive components, reduces rework costs, improves yield and detection accuracy, and prevents defective products from flowing into subsequent processes.
