  • Plasma display device
    Patent number: 6144349
    Abstract: The present invention relates to a plasma display device which limits a generation of electromagnetic wave. The plasma display device has first and second drive circuits for applying a drive voltage to first and second display electrode pair. Further, a direction of a charge current flowing at said first display electrode pair when said drive voltage is applied by said first drive circuit is opposite on said plasma display panel to a direction of a charge current flowing at said second display electrode pair when said drive voltage is applied by said second drive circuit. According to the present invention, a transitional charge/discharge current, which is generated upon the application of a drive voltage to one of the display electrodes, and a light emission discharge current flow in opposite directions on the panel. Thus, electromagnetic waves that are generated by the inductances of the display electrode pair cancel each other out.

  • Flat display
    Patent number: 5973655
    Abstract: A flat display comprising an address current detecting means 3 for detecting a value of address current consumed for each frame to be displayed on the flat display, a comparator 4 for comparing the address current value detected by the address current detecting means 3 with a given reference value, and an address frequency control means 5 for controlling address frequencies related to a display frame in response to the output of the comparator 4.

  • Flat display
    Patent number: 5583527
    Abstract: In a flat display, an address current detecting unit detects a value of address current consumed during each display frame, a comparator compares the address current value detected by the address current detecting unit with a given reference value, and an address-frequency control unit controls address frequencies related to the display frame in response to the output of the comparator.
