AI Technical Summary
Technical Problem
In under-display camera solutions, how can we ensure the light transmittance and display effect at the location of the imaging module on the display substrate while increasing the screen-to-body ratio of the display device?
Method used
Design a display substrate, including a substrate and a pixel defining layer. The pixel defining layer has multiple openings in the display area. The shape and arrangement of the sub-pixel openings are specifically designed to ensure a balance between light transmittance and display effect.
Benefits of technology
While ensuring the pixel aperture ratio of the under-display camera area, diffraction phenomena are reduced or eliminated to improve display and imaging effects.
