ABSTRACT:
An array includes first and second light active units with a difference in effective size that would be sufficient to produce an artifact in images if the first and second units were adjacent. Instead of being adjacent, the first and second units are separated by a spacing in which intermediate units form a series extending from the larger unit to the smaller unit. Every unit in the series has an effective size less than the preceding unit, but the size differences between adjacent units are insufficient to produce an artifact. The array can be a display, and the first and second units can be light control units in a column, with the difference in effective size resulting from paired lines adjacent the smaller unit. Spacings between lines bounding rows of light control units can be different, or rows can have nearly constant pitch but dark matrix can define aperture boundaries that have different effective sizes.
