Abstract:
A flat panel display, comprising:a flat panel including a signal wire arrangement for transmitting image drive signals to pixels, a row signal wire arrangement for transmitting scanning signals, and a column signal wire arrangement for transmitting image signals; a master drive output unit installed on the flat panel, the master drive output unit generating output signals for driving pixels and supplying the output signals to a corresponding signal wire arrangement; and a slave drive unit installed on the flat panel, the slave drive unit supplying compensation signals to the signal wire arrangement before the output signals of the master drive output unit are charged thereto, and thereby enabling the output signals of the master drive output unit to be easily charged, wherein the slave drive unit comprises: a slave control unit for generating an on/off switch control signals and a three-state buffer control signal and for outputting the control signals at predetermined times; an on/off switch that shorts or opens according to the on/off switch control signals; a three-state buffer converter for outputting one of a first voltage, a second voltage and a high-impedance state according to the three-state buffer control signals; and a slave buffer amp for converting signals received from the three-state buffer converter into signals of the same voltage but amplified by a predetermined current gain, and transmitting the converted signals to the on/off switch.
