Energy-Efficient High Dynamic Range Display

The emerging high dynamic range (HDR) displays provide a much larger range of luminance compared to conventional low dynamic range (LDR) displays, thereby improving the visual impression of the displayed images. This is achieved by expanding the effective dynamic range towards darker and lighter luminance through a combination of a conventional TFT LCD panel and a space-variant background lighting (backlight) system. The backlight can either be a projector or an array of high-luminance LEDs that are individually addressable. Moreover, the backlight can be composed of several independent panels whose power or luminance can be controlled separately. Such features enable the design of energy-adaptive displays which in turn motivates the development of energy-aware applications.
