Abstract
An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the optical sensor. Each transparent window may be devoid of thin-film transistors and other display components. The plurality of transparent windows is configured to increase the transmittance of light through the display to the sensor. The transparent windows may have non-periodic portions to mitigate diffraction artifacts in light that passes through the display to the optical sensor. The transparent windows may be shifted by a random amount in a random direction relative to a grid defining point and/or may be randomly rotated to increase the non-periodicity. A transparency gradient may be formed between the transparent windows and the surrounding opaque portion of the display. The transparent windows may be defined by non-linear edges.
