Abstract
A plasma display apparatus including a capacitive load and a driving circuit is provided. The plasma display apparatus includes a driving power source supplying a drive voltage to the capacitive load and a reference potential terminal supplying a reference potential to the capacitive load. A drive IC is coupled to the driving power source.
Claims3
A flat panel display apparatus comprising a display panel having a plurality of display cells and a driving circuit for driving the display panel,
- the driving circuit including:
- a driving power supply source to generate a driving voltage;
- a driving module in which a drive IC to drive the plurality of display cells of the display panel and a power supply terminal to supply power to the drive IC are formed to be a module;
- and
- a power distributor that is arranged outside the driving module and that is connected between the driving power supply source and the power supply terminal of the driving module, and
- the driving voltage being supplied to the power supply terminal of the driving module via the power distributor,
- wherein an impedance of the power distributor is equal to or higher than one-tenth of a conductive impedance of the drive IC.
