Infrared remote control device for plasma display device

An infrared remote control device used for a plasma display device in which each field is divided into an address period for setting a discharge cell that constitutes each pixel to either a light emission cell or a non-light emission cell in accordance with pixel data and an emission sustaining period for causing only the discharge cell set as the light emission cell to emit light, in order to drive the plasma display panel, the infrared remote control device comprising:

• a light-reception portion for obtaining a light-reception signal by reception of infrared rays and for demodulating the light-reception signal;
• a removing device for removing a signal component during the emission sustaining period from an output signal of the light-reception portion and for outputting a remaining signal component after removing;
• a delaying device for delaying the output signal of the removing device in a field unit;
• a logical-sum device for calculating a logical sum of the output signal of the removing device and an output signal of the delaying device;
• and
• a determining device for determining a content of a remote control signal that controls an operation of the plasma display device in accordance with the logical sum calculated by the logical-sum device.
