ABSTRACT:
A Digital-Analog (D/A) converter, a data driver and a flat panel display using the D/A converter and data driver includes a controller to generate a first control signal or a second control signal according to a bit value of data supplied thereto. A voltage generator is disposed between a first voltage and a second voltage, and includes a plurality of resistors for dividing the first voltage and the second voltage. First switches are coupled to respective nodes of the resistors. Capacitors are respectively coupled to the first switches, and are charged with turning-on or turning-off the first switches. Second switches are respectively coupled to the first switches, and transfer the first control signal or the second control signal to the first switches. Shift registers are respectively coupled to the second switches, and supply reset signals or shift signals.
