Display screen, terminal device and imaging control method for under-screen camera

A terminal device, comprising:

• a display screen comprising:
• a transparent substrate, wherein an upper surface of the transparent substrate comprises a luminescent material;
• and
• a diffraction compensation pattern, disposed below the transparent substrate, and configured to compensate a diffraction image resulted from incident light passing through the luminescent material;
• and
• an under-screen camera, disposed behind the display screen and configured to collect incident light passing through the display screen.

An imaging control method for an under-screen camera, comprising:

• determining, by a terminal device, a pattern style of a diffraction compensation pattern, wherein the terminal device comprises a display screen and the under-screen camera disposed behind the display screen and configured to collect incident light passing through the display screen, the display screen comprises a transparent substrate and the diffraction compensation pattern, an upper surface of the transparent substrate comprises a luminescent material, and the diffraction compensation pattern is disposed below the transparent substrate and configured to compensate a diffraction image resulted from incident light passing through the luminescent material;
• generating, by the terminal device, the diffraction compensation pattern below the transparent substrate based on the pattern style of the diffraction compensation pattern;
• and
• performing, by the terminal device, imaging control for the under-screen camera based on the diffraction compensation pattern.

An imaging control apparatus for an under-screen camera, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor,
• wherein the processor is configured to:
• determine a pattern style of a diffraction compensation pattern, wherein a terminal device comprises a display screen and the under-screen camera disposed behind the display screen and configured to collect incident light passing through the display screen, the display screen comprises a transparent substrate and the diffraction compensation pattern, an upper surface of the transparent substrate comprises a luminescent material, and the diffraction compensation pattern is disposed below the transparent substrate and configured to compensate a diffraction image resulted from incident light passing through the luminescent material;
• generate the diffraction compensation pattern below the transparent substrate based on the pattern style of the diffraction compensation pattern;
• and
• perform imaging control for the under-screen camera based on the diffraction compensation pattern.
