DRIVER IC AND ORGANIC LIGTH EMITTING DISPLAY USING THE SAME

摘要

PURPOSE: A driver ic and an organic light emitting display using the same are provided to change voltage of a data signal according to the fluctuation of the voltage of a first power source using a reference voltage which is used for generating the voltage of the data signal. CONSTITUTION: A pixel unit(100) displays an image according to a data signal, a scanning signal, a first power source and a second power source. A gamma corrector(500) generates the gamma voltage corresponding to each gray scale using the reference voltage. The voltage generation unit(600) generates the reference voltage. A data driver(200) generates the data signal using the image signal and the gamma voltage. The data driver transfers the data signal the pixel unit. A scan driver(300) transfers the scanning signal to the pixel unit. A power supply unit(400) transfers the first power source and the second power source to the pixel unit.
