Abstract
Aspects of the subject technology relate to electronic devices with displays. A display may include an array of display pixels and control circuitry for operating the display. In some scenarios, interference signals from other components of the electronic device or additional external devices can couple to the control circuitry for the display and cause distortions in displayed data. Display frames may be displayed by an electronic device display with a varying phase. The varying phase display frames may each include a distortion pattern that also varies from frame to frame due to the varying phase. The varying distortion patterns may average out or visibly cancel when viewed by a user such that no visible artifact of the interference signal is seen by the user. The varying phase can be actively tuned to the interference signal if desired.
