ORGANIC LIGHT EMITTING DISPLAY AND DRIVING METHOD FOR THE SAME

摘要

An organic light emitting display and a driving method thereof are provided to improve The display quality, to implement the stable display and to increase the accuracy of the sampling. An organic light emitting display comprises a display unit, a plurality of monitoring pixel(125) and a controller(170). In the display unit, a plurality of sub pixels(120) is arranged in the top of the substrate as the matrix type. The plurality of monitoring pixels is located on the outside surface of the substrate of the display unit. The controller corresponds to the radiation ratio of the whole display unit and sets up the radiation ratio of the whole monitoring pixel in order to control the voltage to be supplied to the sub pixel based on the amount of the current supplied to the monitoring pixel. The controller supplies the control signal to the monitoring pixel in order to group over one and radiate.
