ORGANIC LIGHT EMITTING DISPLAY DEVICE AND DRIVING VOLTAGE SETTING METHOD THEREOF

摘要

PURPOSE: An organic light emitting display device and a driving voltage setting method thereof are provided to power consumption by setting an optimum driving voltage. CONSTITUTION: A power supply unit(110) supplies a driving voltage to a display panel(100). A power supply unit is installed inside a varying circuit. The varying circuit varies the driving voltage. A current detector(120) detects a panel current. The panel current is flowed into the display panel. An optimum driving voltage is set by calculating the change rate of the panel current.
