Abstract
An autostereoscopic display device has a particular design of display panel for use with a forming arrangement having non-slanted view forming elements (being for example a lenticular or parallax barrier array). The display panel sub-pixels incorporate a slant into their shape. The display panel is designed to enable low slant angles while still enabling efficient mapping of the 2D display panel pixels to the 3D pixels, allow for square 3D sub-pixels on rectangular grid which gives better distribution of color components with improved uniformity and improved rendering in 3D mode.

An autostereoscopic display device comprising:
- a display comprising an array of pixels,
- wherein the pixels are arranged to produce a display,
- wherein the array defines a display area, the display area having a first side and a second side and a top and a bottom,
- wherein the pixels are arranged in orthogonal rows and columns of sub-pixels,
- wherein the rows are parallel to the top and the top is parallel to the bottom,
- wherein the columns are parallel to the first side and the second side is parallel to the first side;
- and
- a view forming arrangement, the view forming arrangement arranged in registration with the display, wherein the view forming arrangement is arranged to project a plurality of views towards a user, wherein each of the plurality of views are oriented in different directions,
- wherein the sub-pixels comprise at least two opposing sides which are slanted with respect to the sides of the display area,
- wherein a sub-pixel color pattern for the rows repeats every two rows to define a plurality of row sets,
- wherein each row comprises sub-pixels of at least two colors,
- wherein no adjacent sub-pixels in a direction parallel to the top have the same color, and
- wherein no adjacent sub-pixels have the same color in the first side direction.
