Abstract: Drive circuits for a flat panel display using a matrix of DC responsive phosphor dots are disclosed. Enabled row conductors receive a pulse of DC potential equal to +HV, whereas disabled row conductors receive +HV/.sub.2. Enabled column conductors receive zero potential, whereas disabled column conductors receive +HV/.sub.2. HV is in the range 90 to 140V. This allows semiconductor integrated circuit display drivers to be used in conjunction with the column conductors. Discrete transistor complementary-pair drivers are used for the row conductors. Scanning and character generation functions are achieved by the use of semiconductor integrated circuits. A pulse-width brightness control operates by selection of one of several logical combinations of the outputs of a counter. Two or four column driver circuits are provided to simplify high density connection problems and a divider circuit causes the column driver circuits to be addressed in sequence.
