PHOTO SENSOR AND LIGHT EMITTING DISPLAY USING THE SAME

摘要

PURPOSE: An optical sensor and an organic light emitting display device using the same are provided to prevent yield lowering and quality lowering and reduce the deviation of brightness measured value. CONSTITUTION: According to scan signals and data signals, a pixel unit(100) displays images. A scan driver(400) transfers the produced scan signals to the pixel unit. A data driver(300) transfers the produced data signal to the pixel unit. An optical sensor(200) comprises a sensor sensing the brightness of ambient light and a controller outputting the brightness control signal which controls the brightness of image.
