摘要： A controllable reflecting device having an array of bi-axial mirrors that are capable of pivoting in at least four directions is described. At least three primary colored light beams are directed at each of the bi-axial mirror in three of the four pivoting directions, one for each of the primary colored light beams and a single colored beam is reflected and directed toward a projection lens. In the fourth pivoting direction, no color beam is directed to the projection lens and black is projected.

摘要： A horizontal deflection winding centering circuit includes a Darlington transistor and a diode. The Darlington transistor and diode form a non-linear network that is coupled in series with an inductor. The series arrangement of inductor and non-linear network is coupled in parallel with a horizontal deflection winding. The base voltage of the Darlington transistor is produced by a voltage divider coupled in a current path of the inductor current.

摘要： A varactor tuner frequency controller wherein a tuning voltage is developed for optimumly tuning a VHF tuner or a UHF tuner to any one of a plurality of channels. A capacitor utilized to store charge for developing the tuning voltage is discharged by means of a pulse developed by a monostable circuit which is gated by a bandswitch reset pulse. Charging of the capacitor is provided for by a positive current source which supplies a substantially constant current to the capacitor in the absence of a hold signal, the hold signal only being present when a selected channel has been reached. In the presence of a hold signal, the current supplied by the positive current source is modified in accordance with an automatic fine tuning signal, and a negative current source supplies a substantially constant current to the capacitor approximately equal to the current supplied by the positive current source in the absence of the hold signal to effect a stopping of the sweep. When irregular spaced channels are being tuned, the negative current source is momentarily disabled in the presence of a hold signal to provide for an incremental sweep of the tuning voltage to place the tuning voltage within a range which will provide for proper automatic fine tuning operation.

摘要： A controllable reflecting device having an array of mirrors that is combined with a tiled color filter such that each micro mirror reflects a single primary color is described. The tiled color filter, in the light path between a light source and the mirror array, images one micro mirror wide primary color stripes on the micro mirror array in a repeating sequence (for example RGBRGB etc.). A movable mirror or lens in the optics path between the micro mirror array and a projection screen is moved to displace the image formed by the micro mirror array and projected to the screen such that for each image all pixel positions at the screen sequentially see a micro mirror of each primary color.

摘要： A projection display comprises three cathode ray tubes each having a deflection yoke and convergence yoke and each tube generating a raster for projection. One of the three cathode ray tubes has the convergence yoke coupled for current flow in a direction opposite to that of the other two convergence yokes. An amplifier is respectively coupled to each convergence yoke for convergence correction of each raster. A convergence circuit supplies correction signal values that are coupled to each respective amplifier such that convergence correction by the other two convergence yokes is responsive to a difference between the correction signal value coupled to the one convergence yoke and the correction signal values coupled to the other two convergence yokes.
