Abstract
A plasma display device which stops power supply or drive of a device by detecting an abnormality. The plasma display device is provided with a panel section (11) which has an address electrode (14) and performs display based on inputted display data, and a circuit section having an address drive circuit (17). The plasma display device is further provided with a means (2) for calculating a switching number of times of the address drive circuit (17) based on the inputted one or more display data; a means (2) for calculating a predicted current value (predicted power consumption value) by predicting consumption at the address drive circuit, based on the switching number of times obtained by the calculation; a means (3) for detecting a current consumption value (actual power consumption value) actually consumed at the address drive circuit (17), based on the display data; and a means (2) for comparing the predicted power consumption value with the actual power consumption value and judging whether it is abnormal.
