摘要： A deflection yoke device includes a deflection yoke for deflecting electron beams in horizontal and vertical directions, the electron beams being emitted from an electron gun of a color cathode ray tube; coma correcting coils positioned on an electron gun side of the deflection yoke so as to be opposed to each other in such a manner that the electron beams pass therebetween; and a pair of cores around which the coma correcting coils are wound, wherein a sliding mechanism is further provided for allowing each of the coma correcting coils to be slidable with respect to the corresponding core. Therefore, a misconvergence can be corrected by a simplified configuration without reducing a sensitivity of the coma correcting coils.

摘要： Horizontal line misconvergences produced at screen upper and lower portions, among rasters displayed by side electron beams are corrected without producing degradation in vertical deflection sensitivity so much and changing horizontal trapezoidal distortion. In a deflection yoke provided with a top-and-bottom pair of saddle-type horizontal deflection coils and a right-and-left pair of saddle-type deflection coils and mounted to and used in a color cathode ray tube having an in-line arranged electron gun, a pair of sub-cores is provided from side to side or above and below on the electron gun side of the deflection yoke. At least one pair of correction coils is wound around each of the pair of sub-cores. The one pair of correction coils is connected in series with vertical deflection coils in such a manner that respective magnetic poles produced from the one pair of correction coils become identical to the pole of a cathode ray tube axis, and a variable resistor is connected in parallel with the one pair of correction coils to change a current that flows through the one pair of correction coils.

摘要： A light-emitting color display system is provided having an optical sensor system in which a plurality of photosensors are directed towards the light source of the light-emitting color display system to provide outputs proportional to the light energy associated with each color. A processing system responds to the outputs over time with the initial outputs and provides a mechanism to correct color changes in the display system. The color light-emitting display system has a second plurality of photosensors directed away from said light-emitting color display system for providing outputs related to the different illuminants and allowing compensation of the light-emitting color display system for the illuminants.

摘要： A method and system for providing two-dimensional convergence correction for a color cathode ray tube (CRT) is disclosed. The CRT displays an input video signal comprising a stream of video scan lines which include red, green and blue color signals that are to be displayed on corresponding scan lines and subpixel locations of a display screen. The method and system include storing a plurality of scan lines from the video signal into a buffer. For a particular red, green and blue color signal, horizontal and vertical distortion of the red and blue subpixels in relation to a position of the green subpixel on the display screen are measured. Then, at least one math function is generated that mathematically represents the distortions. Finally, the math functions are applied to control circuitry to control timing of red and blue subpixels read from the frame buffer so that output of the red and blue subpixels are coincident with output of the green subpixel on the display screen.

摘要： A display device scans a phosphor screen with three independently modulated ultraviolet beams. The screen is coated with three types of light-emitting phosphor dots, each emitting a different color of visible light when illuminated by ultraviolet light. A color separator such as an aperture mask or lens array directs each ultraviolet beam onto phosphor dots of one of these three types. Two or more of these display devices can be combined to obtain a larger screen size.
