Abstract: To provide a data displaying method, a computer system, and a computer-readable recording medium. A data displaying method employed for a computer system that includes a computer means 2 with a database DB; display means 3; and pointer means 4 for entering a position on the screen of the display means 3. The method includes a step of reading data from the database DB and plotting the data on the screen of the display means 3 with respect to the first variable so as to plot a main graph; a step of deciding whether or not an input from the pointer means 4 is a request for plotting data related to the second variable; a step of deciding coordinate data of a position of the main graph displayed on the screen of the display means 3; and a step of searching the coordinate data from the database DB.

Abstract: A microstrip-type of circuit board is used as a source driver for a liquid crystal display. Video signal buses extend in a longitudinal direction on the board. Along a centerline of the longitudinal direction of the board, there are provided through vias to which a signal from a tab driver is propagated. Each video signal bus has a plurality of through vias disposed symmetrically with respect to the though vias disposed along the centerline of the longitudinal direction of the board, with tab leads electrically connected to the symmetrically disposed through via. The substantial symmetry of the circuit board provides the advantage of substantially suppressing EMI.

Abstract: It is an object of the present invention to restrict EMI radiation at a specific frequency by inserting a delay time that is effective for that frequency. The feature of the present invention is to provide a delay generator that can selectively alter delay times. The delay generator comprises: delay means, which is connected to a plurality of data input lines, and which has a plurality of delay paths for the generation of a plurality of alternative delay times; a register for storing a digital value of pre-determined bit; and selection means for selecting one of the delay paths in consonance with the digital value and for providing the selected delay path for the signal lines.
