PLASMA DISPLAY APPARATUS

摘要

PURPOSE: A plasma display device is provided to secure reliability of an operation by supplying a driving signal stably. CONSTITUTION: A driver supplies the bias voltage and a reference voltage of a bias voltage to an electrode. A first controller outputs a first control signal for terminating the supply of the reference voltage in a first malfunction mode in which the bias voltage and the reference voltage are provided at the same time. A first logic circuit receives a first control signal and terminates the supply of the reference voltage. A second controller(410) outputs a second control signal for terminating the supply of the reference voltage in the second malfunction mode in which the sustain voltage and the reference voltage are supplied. A second logic circuit(420) receives a second control signal and terminates the supply of the reference voltage.
