US Patent 9250446 Autostereoscopic display device

The invention provides a autostereoscopic display device with a particular design of lenticular lens array (lens pitch and slant angle) to optimize the quality of the views provided to the user, when a multi-primary pixel layout is used, with at least four sub-pixels of at least three different colors. The slant angle and lens pitch is related to the pixel pitch (in the row and column directions) as well as the number of different color sub-pixels.
