Abstract

A display system comprising a set of light sources that emit a set of frequencies that are capable of exciting a set of quantum dots is disclosed. The display system further comprises a controller that receives input image data to be rendered by the display system and sends out control signals to various components. In one embodiment, the display system may further comprise one, two or more modulators that illuminate the set of quantum dots to form a final rendered image. In one embodiment, the set of light sources optionally comprise a light of substantially uniform polarization - e.g., laser light sources - and may be modulated according to control signal from said controller. Other optional components may comprise a starting polarizer, a mid-polarizer, a first laser light filter, a finishing polarizer and a final laser light filter / reflector.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 914,055, filed December 10, 2013, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to display systems, and more particularly, to high dynamic range (HDR) display systems. Background technique [0004] Conventional LCD display systems are well known in the art - but are known to not be very energy efficient. A conventional display typically includes a backlight, a volume diffuser, an optional light shaper, an initial polarizer, a liquid crystal display (usually comprising a liquid crystal layer followed by a color filter), an end polarizer, and a Watch the optional final diffuser layer. LEDs are common lights used in high-efficiency displays, converting about 15 percent of electricity into light. A volume diffuser can be used to spread the light from the backlight evenl...
