Abstract
An organic light emitting diode (OLED) display is disclosed. The OLED display includes a display panel including a plurality of pairs of data lines, a plurality of gate line groups crossing the pairs of data lines, and a plurality of pixels each having a drive thin film transistor (TFT) and an organic light emitting diode at each of crossings of the pairs of data lines and the gate line groups, a timing controller generating a non-overlap signal, and a sample and hold block that removes an overlap period between adjacently generated first holding clocks using the non-overlap signal to generate second holding clocks that do not overlap each other, applies sampled threshold voltages of the drive TFTs of the pixels to an output node in response to the second holding clocks, and discharges the output node in the overlap period in response to the non-overlap signal.
