Abstract:
A method of imaging using an active matrix liquid crystal display device comprising:providing an active matrix array of transistor circuits and pixel electrodes, each pixel electrode being electrically connected to a transistor circuit that actuates a pixel electrode;providing a layer of liquid crystal material positioned between the pixel electrodes and a counter electrode to form a display structure such that actuation of the pixel electrodes controls transmission of light through a volume of the liquid crystal material;providing a diffractive optical element optically coupled with the active matrix array to disperse light of different colors through different volumes of the liquid crystal material;directing light from a light source through the display device while selectively actuating the pixel electrodes to form an image with the display device; andmagnifying the image with a lens.
