Classification: CPC G  H | IPC G  H

Claim 0:
1. A display for directional control of an image to an observer, said display comprising:
a plurality of image pixels,
each image pixel defining an area having a plurality of subpixels,
each subpixel being addressable for emitting light in a direction towards said observer,
each pixel comprising
a thin film stack of an electroluminescent layer for generating substantially white light,
a color filter for transmitting a first wavelength or wavelength range of said substantially white light in a first time interval and a second wavelength or wavelength range substantially of said white light in a second time interval such that a color perceived by said observer being a combination of said first wavelength or wavelength range and said second wavelength or wavelength range,
an optical element for focusing light from a sub pixel of said plurality of subpixels,

said optical element having a focal point between said optical element and a point in front of and infinitely far away from said optical element,
said optical element having a diameter greater than 30% of an image pixel pitch, and said display comprising a single optical element per image pixel.
