This publication describes systems and techniques to account for an active display area around a camera aperture in a “hole-punch” style display of an electronic device to reduce a light-leaking effect caused by pixels surrounding the camera aperture. Illuminated pixels that are proximate to the camera aperture can degrade a quality of an image captured by a camera sensor by preventing the sensor from properly detecting light from a targeted image, such as a user’s face. To counteract this image degradation, techniques described herein override the illumination control for pixels surrounding the hole in the display. For example, responsive to the camera being engaged, one or more rings of pixels around the display hole can be controlled to have a decreased illumination level based on ambient brightness. The decreased illumination can involve being commanded to be turned off or being commanded to illuminate at a lower level. With less light emanating from pixels that are proximate to the display hole, there is less light pollution funneled into the camera aperture to affect the camera sensor.
