Abstract
A display unit includes a display region and a border region. The display region is configured to include a dark state. A diffusing member is positioned adjacent to the border region such that the diffusing member is coextensive with the border region. A first electromagnetic ray bundle incident on the display region in the dark state produces a first bidirectional reflection distribution function. A second electromagnetic ray bundle incident on the border region produces a second bidirectional reflection distribution function. The diffusing member is configured such that the first bidirectional reflection distribution function is substantially identical to the second bidirectional reflection distribution function. The diffusing member may include a base layer and a surface hologram recorded onto the base layer. The surface hologram is configured to encode a spatial pattern in at least one of the opacity, density, and surface height of the base layer.
