  • Patent number: 7030796
    Abstract: An analog-to-digital converting apparatus for rapidly processing a plurality of analog input signals at a high rate and a display device using the same. The apparatus includes a clock signal generator that generates a clock signal with a predetermined frequency; a control signal generator that generates a switching control signal using the clock signal; a multiplexer (MUX) that receives and selectively outputs signals of the plurality of analog input signals according to the switching control signal; and an analog-to-digital converter (ADC) that converts an analog signal selected and output by the MUX to a digital signal.

  • Publication number: 20040008289
    Abstract: Provided are an apparatus and method for controlling CRT focusing in a television, and more particularly, an apparatus and method for separately controlling focusing of R, G, and B cathode ray tubes in a television using a triple tube type optical system based on a digital method. The apparatus includes a memory, a controller, and an R/G/B focusing correction signal generator. The memory stores focusing correction data of R, G, and B cathode ray tubes for a position of a screen. The controller reads and outputs the focusing correction data of the R, G, and B cathode ray tubes from the memory for the position of the screen, based on horizontal and vertical synchronization signals. The R/G/B focusing correction signal generator calculates the focusing correction data of the R, G, and B cathode ray tubes read from the memory and generates R, G, and B analog focusing correction signals that will be applied to R, G, and B coils.
