ACTIVE ORGANIC LIGHT-EMITTING DISPLAY

摘要

PURPOSE: An active organic light emitting display device is provided to quickly compensate the deterioration of the active organic light emitting display device by sensing deterioration in an emission section. CONSTITUTION: A data driver(120) changes correction data into an analog correction signal and generates a driving signal according to the analog correction signal. A selecting unit(130) selects a charging path for programming at a programming section according to the driving signal and selects a deterioration detection path at an emission section. A pixel unit charges a value corresponding to the correction data at the programming section according to the driving signal and flows current into an organic light emitting diode at the emission section according to the charged value. An ADC(160) detects a deterioration voltage with deterioration information from the organic light emitting diode of the pixel unit at the emission section.
