Abstract: Embodiments of the present invention generally provide an apparatus and method for forming a display screen assembly that comprises multiple panel assemblies which are positioned to form a tiled display device that has improved visual characteristics, is easy to assemble and has a reduced manufacturing cost. In general, each panel assembly is formed so that when it is positioned in a display screen assembly the grid pattern, formed by the gap between the illuminated regions in adjacent panel assemblies, can be minimized. In one embodiment, the unwanted visual effect of the grid pattern is mitigated by minimizing and controlling the space, or gaps, formed between the illuminated area in adjacent panel assemblies. Embodiments of the present invention may also provide an apparatus and method for forming a single panel assembly that is used to display an image.

Abstract: Implementations of actuators that use flexures to provide support to the actuators and pivoting mechanisms to the actuators. Such actuators can be electromagnetically activated actuators that include a magnet stator and a coil rotor mounted on a flexure.
Abstract: Scanning beam display systems that scan one servo beam and an excitation beam onto a screen that emits visible light under excitation of the light of the excitation beam and control optical alignment of the excitation beam based on positioning of the servo beam on the screen via a feedback control.

Abstract: Scanning beam systems based on a two-dimensional polygon scanner with different reflective polygon facets tilted at different tilt facet angles to use rotations of the polygon scanner to scan optical beams both horizontally and vertically on a surface which can be a display screen or a printing surface.
Abstract: Laser display systems using at least one scanning laser beam to excite one or more fluorescent materials on a screen which emit light to form images. The fluorescent materials may include phosphor materials.

Abstract: Display devices and systems including television sets, and systems, apparatus and methods for delivering information and providing services through display devices and systems. The display used in the described systems and methods is capable of receiving one or more TV programming channels and an independent designated application channel and having at least a first display window and a second display window separated from each other without spatial overlap on the screen. The information sent over the designated application channel to the display is displayed on the first display window while simultaneously displaying one of the TV programming channels on the second display window. A viewer control mechanism is provided in the display to allow the viewer to switch the information received from the designated application channel from the first display window to the second display window and switch back at the viewer's choice.

Abstract: Various phosphor compositions and organic compounds can be used in fluorescent layers for scanning beam displays. In general, one aspect of the subject matter described in this specification can be embodied in method of adjusting an emission spectrum of a phosphor material used in a display system that includes a fluorescent layer that absorbs an excitation light at a single wavelength and emits visible light. The method includes generating a binder mixture by combining one or more non-phosphor organic compounds with a binder material, wherein the binder mixture substantially transmits the excitation light and substantially absorbs a portion of the emission spectrum of the phosphor material. The method also includes combining the binder mixture with the phosphor material.
