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.

摘要： In a method for driving a display, one frame may be divided into more sub frames than a number of bits of data. A time period of the one frame may be divided into a number of periods corresponding to a number of scan lines multiplied by the number of sub frames. A start position of the sub frames may be set based on a bit weight of the data so that gradations are linearly expressed. Remainders of the sub frames may be obtained by dividing the start position of the sub frames by the number of sub frames. A line number of a scan line to which a scan signal is supplied may be obtained based on the time period of the one frame, the start position of the sub frames, and the number of the sub frames.
