Scheme for operating under-display camera to prevent light interference from display

An electronic device, comprising:

• a display panel;
• an under-display camera below the display panel;
• a first control circuit coupled to the display panel, the first control circuit configured to:
• turn on a first row of pixels in a first portion of a display panel during at least a part of a first light emission period of a display frame,
• turn off the first row of pixels during a first non-light emission period in the display frame;
• turn on a second row of pixels in a second portion of the display panel during at least a part of a second light emission period of the display frame;
• and
• turn off the second row of pixels during a second non-light emission period in the display frame;
• and
• a second control circuit coupled to the first control circuit and the under-display camera, the second control circuit configured to:
• instruct a first row of sensors in the under-display camera to perform sensing during a first light sensing period that overlaps with the first non-light emission period of the first row of pixels, the first row of sensors overlapping with the first row of pixels;
• instruct a second row of sensors in the under-display camera to perform sensing during a second light sensing period that overlaps with the second non-light emission period of the second row of pixels, the second row of sensors overlapping with the second row of pixels.

A non-transitory computer-readable storage medium storing instructions thereon, the instructions when executed cause a processor to:

• turn on a first row of pixels in a first portion of a display panel over an under-display camera during at least a part of a first light emission period of a display frame;
• turn off the first row of pixels during a first non-light emission period in the display frame;
• perform sensing at a first row of sensors in the under-display camera during the first non-light emission period of the first row of pixels, the first row of sensors overlapping with the first row of pixels;
• turn on a second row of pixels in a second portion of the display panel during at least a part of a second light emission period of the display frame;
• turn off the second row of pixels during a second non-light emission period in the display frame;
• and
• perform sensing at a second row of sensors in the under-display camera during the second non-light emission period of the second row of pixels, the second row of sensors overlapping with the second row of pixels.
