Definitions

  • the level of the Y-axis deflection signal shown in FIG. 5b is lowered at portions between time instants T to T and T to T of the enlargement signal shown in FIG. 5c with the result that at the center of the enlarged pattern, the degree of deflection is decreased in accordance with the magnifying power.
  • the deflection frequency may be low and it is possible to adjust the spacing between displayed patterns by varying the level of such low frequency deflection signal in accordance with the enlargement-reduction signal.
  • the display apparatus which further comprises a grid electrode disposed between said matrix electrodes and said cathode electrode of said cathode ray tube and a digital-analogue converter connected between said supply memory and said grid electrode for converting said enlargement or reduction signal into an analogue signal to maintain at a definite value the brightness of said enlarged or reduced pattern.
  • the display apparatus which further comprises second means responsive to said enlargement-reduction signal from said decoder for energizing said first grid electrode of said cathode ray tube for controlling the quantity of electrons impinging upon said matrix electrodes to regulate the brightness of the pattern displayed on said fluorescent screen.
  • said second means comprises a control responsive to said enlargement-reduction signal for producing a control voltage for energizing said first grid electrode.
