Abstract
A segmented optical shutter () is used with a high-resolution display () to provide a dynamic user interface () for a portable electronic device (). To reduce optical interference corresponding to a correlation function for transmitted light occurring between the photospacers () in the segmented optical shutter () and the black matrix (), the photospacers () are disposed along a light transmitting substrate () of the segmented optical shutter () in a quasi-random arrangement. The quasi-random arrangement, which may include varying the horizontal and vertical placement of the photospacers (), repeating asymmetrical subsections of photospacer configurations, varying the size or shape of the photospacers (), or combinations thereof, misaligns the photospacers () relative to the black matrix () or other elements to reduce optical interference and moiré patterns that may otherwise be perceptible to a user.
