Abstract
An organic light emitting diode display includes a display panel including a plurality of pixels, each pixel including an organic light emitting diode (OLED) and a driving thin film transistor (TFT) configured to control an amount of current flowing in the OLED depending on a difference between a data voltage and a reference voltage, a source driver integrated circuit (IC) configured to produce the data voltages corresponding to data of an input image and apply the data voltages to data lines connected to the pixels, an image analyzer configured to analyze the data of the input image and produce reference voltage control data, and a reference voltage regulator configured to produce the reference voltages varying depending on the input image based on the reference voltage control data and apply the reference voltages to reference lines connected to the pixels.
