Abstract
Disclosed is a PDP driving method which may include generating subfield information that shows ON/OFF states of discharge cells from among a plurality of subfields from input image signals, generating address information that shows ON/OFF states of the discharge cells per subfield from the subfield data, counting the number of the discharge cells that are ON from among the discharge cells from the address data, and controlling a waveform applied during a reset period of a subsequent subfield.
Claims21
A plasma display panel (PDP) capable of dividing a frame into a plurality of subfields to display gray scales, comprising:
- a panel including a plurality of address electrodes and a plurality of first and second electrodes arranged to cross the address electrodes, a discharge cell being formed by an adjacent address electrode and the first and second electrodes;
- a driver for applying a driving voltage to the address electrode and the first and second electrodes;
- and
- a controller for controlling the driver according to input image signals,
- wherein the controller comprises
- a subfield data generator for generating subfield data for showing ON/OFF states of the discharge cell in the subfields from the image signals,
- a subfield data allocator for generating address data for showing ON/OFF states of discharge cells per subfield from the subfield data, and
- a driving controller for counting a number of discharge cells that are ON from among the discharge cells from the address data of one subfield and controlling a waveform applied to a reset period of a subsequent subfield in accordance with the number of discharge cells that are ON.
A method for driving a plasma display panel (PDP) including a plurality of address electrodes and a plurality of first and second electrodes crossing the address electrodes, comprising:
- generating subfield data for showing ON/OFF states of discharge cells from among subfields from input image signals;
- generating address data for showing ON/OFF states of the discharge cells for each subfield from the subfield data;
- and
- determining a number of discharge cells that are ON from among the discharge cells from the address data, and controlling a waveform applied during a reset period of a subsequent subfield in accordance with the number of discharge cells that are ON.
