The keeper's note

A wavelength-multiplexed display where each pixel has multiple discrete emitters at different wavelengths, used for park show lighting/visualization effects.

Abstract

Embodiments herein describe a display device for performing wavelength multiplex visualization (WMV). The display device includes a display screenthat includes a plurality of pixels where each pixel contains at least two discrete emitters that generate electromagnetic radiation at a certain wavelength. By controlling the luminance of the respective emitter, the display device sets the color of the pixel. When performing WMV, the display device uses the pixels to generate a left eye display frame and a right eye display frame. Generally, the left eye frame is generated using a different set of wavelengths than the right eye frame. The user can wear special glasses that have interference filters in the lenses which permit only one of the wavelengths to pass through. As a result, each eye of the user sees only one of the display frames, thereby creating the 3D effects.
