Patent ID: 8525755

Claim:
A method for controlling a matrix plasma display screen comprising rows and columns, the method comprising: sequentially selecting the rows of the matrix plasma display screen; emitting, for each selected row, a state change signal input to a step-up circuit to each column of a set of columns using a first transistor for allowing said each column of the set of columns to change from a first state to a second state, each state change signal comprising a transitional state from the first state to the second state; regulating a rise time of the state change signal by limiting a current flowing through the first transistor; and controlling a control voltage delivered to a control electrode of the first transistor using a control transistor, the control transistor comprising a first electrode coupled to a power supply terminal, a second electrode for delivering the control voltage to the control electrode of the first transistor, and a control electrode directly coupled to the step-up circuit and receiving a boosted state change signal from the step-up circuit.
