Abstract: This specification describes phosphor compositions used in fluorescent layers for scanning beam displays. In general, one aspect of the subject matter described in this specification can be embodied in a display device having a fluorescent layer that absorbs an excitation light at a single wavelength and emits visible light. The fluorescent layer includes a plurality of parallel fluorescent stripes. At least three adjacent fluorescent stripes are made of three different fluorescent materials, which include a first fluorescent material that absorbs the excitation light and emits light of a first color, a second fluorescent material that absorbs the excitation light and emits light of a second color, and a third fluorescent material that absorbs the excitation light and emits light of a third color.
Abstract: Implementations of actuators that use flexures to provide support to 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. A positioning sensor, such as a capacitor sensor, is provided to measure and monitor positioning of the actuator and is coupled to a feedback circuit which uses the measured positioning of the actuator to control the actuator.
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: Techniques and devices use panels or screens with pixels for display or illumination applications to achieve dithered pixel brightness beyond pixel brightness levels set by a digital to analog conversion (DAC) circuit module with a preset DAC resolution between two adjacent DAC levels. In one implementation, when a pixel is to be dictated by a digital pixel signal to operate within an unstable brightness region, a control mechanism is provided to control the DAC circuit module to operate the pixel in the block at a DAC level below the unstable brightness region or at a different DAC level above the respective unstable brightness region, to achieve a perceived brightness level within the respective unstable brightness region.

Abstract: Scanning beam display systems based on scanning light on a fluorescent screen. The screen can include fluorescent materials which emit visible light under excitation of the scanning light to form images with the emitted visible light. Multiple lasers can be used to simultaneously scan multiple laser beams to illuminate the screen for enhanced display brightness. For example, the multiple laser beams can illuminate one screen segment at a time and sequentially scan multiple screen segments to complete a full screen.

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.
