Estimating the term…
A segmented optical shutter (200) is used with a high-resolution display (101) to provide a dynamic user interface (400) for a portable electronic device (100). To reduce optical interference corresponding to a correlation function for transmitted light occurring between the photospacers (209) in the segmented optical shutter (200) and the black matrix (107), the photospacers (209) are disposed along a light transmitting substrate (204) of the segmented optical shutter (200) in a quasi-random arrangement. The quasi-random arrangement, which may include varying the horizontal and vertical placement of the photospacers (209), repeating asymmetrical subsections of photospacer configurations, varying the size or shape of the photospacers (209), or combinations thereof, misaligns the photospacers (209) relative to the black matrix (107) or other elements to reduce optical interference and moiré patterns that may otherwise be perceptible to a user.
A field effect mode electro-optical device comprising a liquid crystal layer defining a black matrix disposed between a pair of transparent substrates and at least one light polarizer layer, wherein one or more substrates comprise a plurality of photospacers disposed in a quasi-random arrangement thereon configured to reduce a correlation function for transmitted light occurring between the plurality of photospacers and the black matrix.
A user interface for an electronic device, comprising:
An electronic device having a user interface comprising a segmented optical shutter and a high-resolution display configured as a dynamic user interface, wherein the segmented optical shutter comprises a liquid crystal material disposed between a pair of substrates and a black matrix, wherein at least one substrate has a plurality of photospacers disposed thereon in a quasi-random arrangement, wherein the quasi-random arrangement comprises misaligning the plurality of photospacers relative to the black matrix.
