AI Technical Summary
The pixel circuitry above the camera in existing display panels used for under-display cameras causes reduced transparency and light diffraction interference, affecting the quality of images captured by the camera.
Design a display panel detection device that uses a camera located below the panel to collect transmitted light beams, and combines a light-emitting module and a detection module to detect transmittance and uniformity. The beam information is then analyzed by integrating sphere homogenization and a spectrometer.
It enables the detection of transmittance and uniformity of the under-display camera display panel, improving the clarity and stability of the images captured by the camera.
