Abstract: A reference voltage generating circuit includes a binary-to-thermometer for converting binary codes into thermometer codes; an internal reference voltage generator for generating an internal reference voltage in response to the thermometer codes from the binary-to-thermometer, wherein the internal reference voltage generator changes a level of the internal reference voltage in response to the thermometer codes; a selector for selecting the internal reference voltage or an external reference voltage in response to a reference voltage select signal; and a voltage regulator for regulating a reference voltage selected by the selector.

Abstract: An optical scanner, a laser image projector using the optical scanner, and a method of driving the laser image projector are provided. The optical scanner includes: a base substrate; a plurality of parallel stationary comb electrodes arranged on the base substrate extending upwards at right angle; a stage having a mirror side at its top side, being separated a predetermined distance above the base substrate; a plurality of parallel driving comb electrodes arranged on the bottom of the stage extending at right angle interdigitated with the stationary comb electrodes; torsion bars formed at both side edges of the stage with a predetermined length to support such that the stage pivots; and supports for supporting the torsion bars such that the stage is suspended above the base substrate. The laser image projector includes the optical scanners using micro mirrors, instead of a horizontal scanning rotating polygonal mirror and a vertical scanning galvanometer, and is driven such that a single horizontal left-to-right scanning is followed by another right-to-left horizontal scanning without redundant flyback interval. Therefore, comparing with a driving method which needs quick returning 5-10 times faster than horizontal scanning rate, the driving speed can be markedly reduced, so that high-speed driving limitations of optical scanner for high-resolution image display can be overcome.

Abstract: An actuator includes a stage having a first direction and a second direction perpendicular to the first direction and seesawing around a third direction perpendicular to the first direction and the second direction with respect to a rotation center axis placed along the first direction. A first support portion supports a seesaw motion of the stage. A base facing the stage under the stage at a predetermined interval is supported by the first support portion. A stage driving portion has a plurality of first driving comb electrodes and a plurality of first stationary comb electrodes corresponding to the first driving comb electrodes which are respectively formed on a lower surface of each of the stages and an upper surface of the base facing the stages. A second support portion supports the first support portion so that the first support portion seesaws with respect to a rotation center axis placed along the second direction. A first support portion driving portion has a second driving comb electrode provided at the first support portion and a second stationary comb electrode fixedly positioned to correspond to the second driving comb electrode to generate a seesaw motion of the first support portion.
