    Abstract: A method for estimating an effective luminance pattern representing a distribution of projected light in a display apparatus involves determining driving values for one or more light sources arranged to project light. The light sources are solid-state light sources such as light-emitting diodes in some embodiments. The method determines an effective luminance pattern for the projected light by determining contributions to the effective luminance pattern for different components of a point spread function and then combining the contributions of the components the effective luminance pattern to yield an estimated effective luminance pattern.

    Abstract: Parallax in an optical device is reduced by apply one or a combination of several disclosed techniques, including reduced solid angle or increased collimation of light sources, increased diffusion/scattering at an output of the device, and/or reflective structures for collimation and containment of reflected light. The techniques are advantageously applied to a backlight LCD display, and particularly to high dynamic range dual modulation displays.
