ORGANIC LIGHT EMITTING DISPLAY AND DRIVING METHOD FOR THE SAME

摘要

An organic light emitting display and a driving method for the same are provided to compensate deterioration of an organic emitting diode and a transistor included in a sub-pixel by correcting an image data signal based on a correction factor. In an organic light emitting display and a driving method, an n-th image data signal is stored in a first memory ROM(131). An N-1 image data signal is stored in a second memory(132), and an operation unit(140) request N-th number image data signal and N-1-th the image data signal in from the first memory ROM and the second memory. The operation unit performs one of four arithmetical operations and generates a correction factor by comparing result k of operation with a reference M. A data driver(151) corrects N-th image data signal based on the correction factor delivered from the operation unit, and the corrected image data signal is supplied to a display unit.
