Electronic Devices Having Ambient Light Sensors With Electrostatic Shields

An electronic device, comprising:

• an array of pixels configured to display images;
• a display cover layer that overlaps the pixels;
• an optical component window in a portion of the display cover layer through which ambient light passes;
• and
• a color ambient light sensor aligned with the optical component window, wherein the color ambient light sensor includes:
• an opaque support structure;
• a light detector integrated circuit that is at least partially surrounded by the opaque support structure, wherein the light detector integrated circuit has a plurality of photodetectors each overlapped by a color filter that is configured to pass a different respective band of visible light wavelengths;
• and
• an electrostatic shield configured to shield the light detector integrated circuit from signal perturbations.

An electronic device, comprising:

• a display having a display cover layer;
• an ambient light sensor window in the display cover layer;
• and
• an ambient light sensor configured to receive ambient light through the ambient light sensor window, wherein the ambient light sensor comprises:
• a light detector;
• and
• a ring of metal at a fixed potential that surrounds the ambient light sensor window and that faces an inner surface of the display cover layer, wherein the ring of metal is configured to serve as an electrostatic shield for the light detector.
