Patent ID: 8384747

Claim:
An autostereoscopic display apparatus comprising: a plurality of colored individually addressable light emitting diode display elements arranged in an array of rows and columns; a plurality of light directing lenticular elements; a diffusion layer switchable between diffusing and non-diffusing, which in a diffusing state cancels out a light directional effect of the lenticular elements, reducing an autostereoscopic mode to a 2-D mode; wherein an internal color order of 2-D triplets changes in at least one of a row and column direction for adjacent triplets is such that in the 2-D mode an inherent loss of spatial resolution is reduced; wherein: the lenticular elements that are arranged along a slanted direction with respect to the columns of individually addressable display elements and a pitch of the lenticular elements is chosen in relation to a pitch of the individually assignable display elements in the row direction according to the number of views required; and the lenticular elements have a central axes extending along the slanted direction, the lenticular elements have a width such that for each of a plurality of the rows, the central axis of the lenticular elements intersect a display element which of a different color than the central axes of the lenticular elements on either side, the central axis of a first lenticular element pastes through a first display element of one triplet in a first row of a first color, the central axis of a second lenticular element next to the first lenticular element passes through a display element of a second triplet of the first row, the second triplet display element being of a second color different than the first color, and the central axis of one of the first and second lenticular elements passing through a display element of a subsequent row of a third color different from the first and second colors to define an autostereoscopic triplet.
