Abstract

Techniques are described herein for supporting user controlled regional display of mixed two and three dimensional content. A display system includes a pixel array, a screen assembly, and a screen surface. The screen assembly and the pixel array are controlled to cause various settings for a regionally adjustable characteristic of the screen assembly to be applied to respective regions of the screen assembly. Each setting specifies a value of the regionally adjustable characteristic that is to control or affect a visual characteristic that is associated with content that is to be presented in the corresponding region. A user may provide an input signal that specifies setting(s) for the regionally adjustable characteristic with respect to specified region(s) of the screen assembly.
