ORGANIC LIGHT EMITTING DISPLAY DEVICE AND METHOD FOR DRIVING THETEOF

摘要

An organic light emitting display device according to the present invention, capable of sensing a characteristics change of a driving transistor for each pixel from the outside to correct the characteristics change in real time, comprises: a display panel configured to include a plurality of pixels having the driving transistor for emitting light emitting elements to a data current based on data voltage; and a panel driver configured to set a sensing section and a displaying section, generate sensing data by sensing at least one among threshold voltage and mobility of the driving transistor during a sensing period, and generate the data voltage by correcting input data according to the sensing data during the sensing period, wherein the panel driver is configured to turn off the light emitting elements of all pixels for each sensing period.
