Patent ID: 7327336

Claim:
A driving apparatus for an electro-luminescence display panel comprising: an electro-luminescent display panel having electro-luminescent light-emitting cells provided at crossings of gate lines and data lines; a current generating circuit that generates a current corresponding to an externally supplied digital data; a data driver that samples the current from the current generating circuit for each horizontal period to generate a data voltage corresponding to the current and applies the generated data voltage to the data lines, wherein the data driver includes: first and second sampling circuits for generating the data voltage; and an analog buffer for buffering the data voltage supplied from the first and second sampling circuits alternately for each horizontal period and applies the buffered data voltage to the data lines; and a timing controller that controls the data driver, applies the digital data to the current generating circuit, and generates a sampling control signal for controlling the data driver to apply the sampled signal to the data driver.
