Abstract: The present invention is a 3D/2D convertible color projection display system with two color LCoS panels, which enable the system to project two orthogonal polarized images. When the two images correspond to different view angles, each eye of an observer wearing a pair of polaroid glasses can only see one of the images, creating a 3D stereoscopic effect. When the two images correspond to the same view angle, then the observer, without any special glasses, can watch regular 2D images with multiple primary colors.

Abstract: In general, in one aspect, the invention features methods that include forming a first lithography mask including a pattern corresponding to an array of filters for a liquid crystal display, using a lithography tool to project an image of the pattern onto multiple locations of a substrate to form an exposed substrate, and forming a second lithography mask from the exposed substrate.

Abstract: A portable data processing apparatus includes a storage storing code associated with a computer program that generates at least one of (a) stereoscopic image data and (b) image data associated with images having two groups of primary colors. A keyboard allows a user to input data used by the computer program or entering commands to control execution of the computer program. A built-in digital projector integrated within the portable data processing apparatus projects onto an external display screen at least one of (a) stereoscopic images and (b) images having two groups of primary colors, the built-in digital projector being integrated within the portable data processing apparatus. A microprocessor executes the code and controls the built-in digital projector to project images based on the image data generated by the computer program.

Abstract: An apparatus includes a digital projector capable of projecting two-dimensional (2D) and stereoscopic images, and a controller to control the digital projector to project images based on the image signals. The controller controls the digital projector to switch from projecting stereoscopic images to projecting 2D images based upon a timer signal indicating that the digital projector has continuously projected stereoscopic images for a first preset period of time.

Abstract: A color LCoS microdisplay device, consisting of a CMOS silicon backplane, a metal reflector array, a lower LC alignment layer, an LC layer, an upper LC alignment layer, a transparent conductive layer, and a cover glass plate, with a micro-dichroic-filter array between the said upper LC alignment layer and the said cover glass plate. Each pixel of the said micro-dichroic-filter array corresponds with a pixel of the said metal reflector array. And the said pixels of the said metal reflector array also serve as electrodes, which can be activated individually with a charge of DC voltage or pulse. Thus a single panel projection color display system is achieved.
