Abstract
According to an aspect, large-angle multi-user autostereoscopic display systems are disclosed that include steerable backlight units that include parallax barriers and diffusers configured to direct backlight through a selectively-transmissive display pixel matrix and lenticular array to form stereoscopic images at a desired viewer location.
Claims18
A system, comprising:
- a backlight that includes an array of backlight pixels, a diffuser, and a parallax barrier located between the array of backlight pixels and the diffuser;
- a lenticular array;
- and
- a display pixel matrix that is selectively-transmissive and located between the backlight and the lenticular array;
- wherein the backlight is configured to activate a subset of the backlight pixels to provide illumination to form a stereoscopic pair of images directed towards a viewer pose.
2 more elements
A method comprising:
- activating a first subset of backlight pixels of a backlight of a display panel to transmit light through a parallax barrier adjacent the backlight, a diffuser disposed adjacent the parallax barrier, a display pixel matrix that is selectively-transmissive and disposed adjacent the diffuser, and a lenticular array disposed adjacent the display pixel matrix so that the display panel emits first display light representative of a first frame in a first direction relative to the display panel;
- and
- activating a second subset of backlight pixels of the backlight to transmit light through the parallax barrier, the diffuser, the display pixel matrix, and the lenticular array so that the display panel emits second display light representative of a second frame in a second direction different than the first direction relative to the display panel.
