AI Technical Summary
Technical Problem
When integrating display and sensor functions, existing electronic devices struggle to achieve high screen-to-body ratios and ultra-narrow bezels without compromising sensing accuracy or resolution.
Method used
In an electronic device, first and second metal layers are provided, each with holes of different widths, to form a light channel, embed a photodetector element, improve sensing accuracy and resolution, and guide light to the photodetector element through a reflective layer or a transparent electrode layer.
Benefits of technology
It achieves improved sensing accuracy and resolution of the light detection element without affecting display functionality, while increasing screen-to-body ratio and reducing bezel size.
