A method of driving the plasma display panel is performed in a plasma display panel driving block constituted by a high power element and a low power element and includes determining the start point of high current generation in the high power element; stopping the signal transmission of the low power element; determining the end point of the high current generation in the high power element; and resuming the signal transmission of the low power element.

Abstract: A plasma display device is configured to apply a scan pulse to a scan electrode in a first subfield, apply a plurality of sequentially delayed address pulses to a plurality of address electrodes crossing the scan electrode. In addition, a plasma display device is configured to apply a plurality of address pulses to the plurality of address electrodes at the same time in a second subfield that has a weight value that is less than a weight value of the first subfield. Thereby, electromagnetic interference (EMI) can be reduced in the first subfield where a substantial amount of EMI is generated, and a low discharge can be reduced in the second subfield that has a high probability of the low discharge being generated.

Abstract: At least one timer is used to prevent a stall condition. If a timer is not active, the timer is started for a data block that is correctly received. The data block has a sequence number higher than a sequence number of another data block that was first expected to be received. When the timer is stopped or expires, all correctly received data blocks among data blocks up to and including a data block having a sequence number that is immediately before the sequence number of the data block for which the timer was started is delivered to a higher layer. Further, all correctly received data blocks up to a first missing data block, including the data block for which the timer was started, is delivered to the higher layer.
