摘要： A data driving circuit for driving pixels of a light emitting display to display images with uniform brightness may include a current sink that is capable of receiving, via a data line, a predetermined current from a pixel to enable the data driving circuit to generate a compensation voltage for the pixel. The compensation voltage may compensate for variations among the pixels of the display. Variations among the pixels may result from different electron mobilities and/or threshold voltages of transistors included in the pixels. The value of the predetermined current may be equal to or higher than a value of a minimum current employable by the pixel to emit light of maximum brightness. The maximum brightness of the pixel may correspond to a brightness emitted by the pixel when a highest one of a plurality of set gray scale voltages is applied to the pixel.
