Abstract
A plasma display device having reduced electro-magnetic interference (EMI) is disclosed. The display device has a filter in front of a plasma display panel. The plasma display panel (PDP) generates EMI noise during operation, and the filter is driven with a noise cancellation signal to at least partially cancel the EMI noise generated by the PDP.
Claims20
A plasma display device, comprising:
- a plasma display panel (PDP), wherein the PDP generates radiated noise when driven with one or more driving signals;
- a radiation screen in front of the PDP;
- and
- a noise elimination circuit configured to drive the radiation screen with a noise cancellation signal, wherein the radiation screen generates noise cancellation radiation configured to at least partly cancel the radiated noise from the PDP.
1 more element
A method of reducing radiated noise from a plasma display device, the method comprising:
- applying driving signals to a plasma display panel (PDP), wherein the PDP radiates noise;
- generating a noise cancellation signal;
- and
- applying the noise cancellation signal to the front of the PDP, wherein noise cancellation radiation generated in response to the noise cancellation signal at least partly cancels the radiated noise from the PDP.
