HIGH DYNAMIC RANGE DISPLAY USING LED BACKLIGHTING, STACKED OPTICAL FILMS, AND LCD DRIVE SIGNALS BASED ON A LOW RESOLUTION LIGHT FIELD SIMULATION

摘要

An HDR display is a combination of technologies including, for example, a dual modulation architecture incorporating algorithms for artifact reduction, selection of individual components, and a design process for the display and/or pipeline for preserving the visual dynamic range from capture to display of an image or images. In one embodiment, the dual modulation architecture includes a backlight with an array of RGB LEDs and a combination of a heat sink and thermally conductive vias for maintaining a desired operating temperature.
