High dynamic range displays having wide color gamut and energy efficiency

摘要

Several embodiments of display systems that have wide color gamut performance are disclosed herein. In one embodiment, a display system comprises a plurality of emitters, said emitters emanating light into an optical path; a first modulator, said first modulator comprising a plurality of colored subpixels and wherein said first modulator transmitting light emanating from said emitters in said optical path; and a color notch filter, said color notch filter placed in said optical path for conditioning or convolving light together with said first modulator.

主权项

1. A display system comprising:
an emitter, the emitter comprising an array of light emitting elements of a same color controlled in a locally dimmed configuration and emanating light into an optical path; a diffuser, the diffuser diffusing the light emanating from the emitter; a color layer configured to receive light from the diffuser and mitigate crosstalk by emitting different passband-like color bands of distinct colors and provide a specific color gamut; wherein the emitter as locally dimmed comprises a first modulator configured to transmit light through the diffuser and the color layer; wherein the color layer placed in the optical path for convolving light together with the first modulator and a second modulator to produce a desired color gamut of the display; a second modulator, comprising an LCD panel, the second modulator modulating light from the first modulator in a manner without color overlap such that each color filter of the LCD panel acts independent of adjacent color filters; and a controller, the controller receiving input image data and sending control signals to the first and the second modulators.
