timing control operation based on the detected temperatures the respective sustaining drivers switching elements s 1 to s 6 can be activated at the same timing therefore drive pulses reset pulse pulses and sustaining pulses can be generated at the same timing as a result the values of electric currents supplied to the row electrodes x 1 to x nk from the output drivers 6 1 to 6 n of the x row electrode drivers 3 1 to 3 n respectively become substantially uniform and similarly the values of electric currents supplied to the row electrodes y 1 to y nk from the scan drivers 8 1 to 8 n of y row electrode drivers 4 1 to 4 n respectively become substantially uniform heat generated in respective elements such as switching elements is distributed to each of the row electrode drivers 3 1 to 3 n 4 1 to 4 n 0050 fig8 shows the configuration of a pdp drive apparatus of another embodiment of the present invention in fig8 the same symbols are used for the same parts as those used in the conventional apparatus shown in fig1 the pdp drive apparatus of fig8 has electric current sensors 17 1 to 17 n for each detecting the value of the current output from the positive terminal of the power source b 2 in each of the sustaining drivers 5 1 to 5 n of the x row electrode drivers 3 1 to 3 n the pdp drive apparatus of fig8 also has electric current sensors 18 1 to 18 n for each detecting the value of the current output from the positive terminal of the power source b 2 in each of the sustaining drivers 7 1 to 7 n of the y row electrode drivers.
