Embodiment Construction

[0054]One of the ultimate goals of display systems is to present images that extend to the limit of the human visual system. For example, a Visual Dynamic Range (VDR) pipeline that captures and maintains the full dynamic range of the human visual system from image capture, through post-production and distribution, to display. Conventional display technologies (LCD, CRT, plasma, and so on) have achieved part of that goal by introducing both spatial resolution and refresh rates that are beyond the visual acuity of a human viewer. However, even the highest quality displays available today are incapable of showing the true luminance (brightness) range that we perceive in real life. Every day we encounter light sources in our natural environment that are several orders of magnitude brighter and of higher contrast than in any conventional display. Dolby® HDR technology enhances image quality and realism far beyond that of conventional displays.

Abstract

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.
