Abstract: A data driver and a display device including the same. The data driver includes a DA converting circuit converting a digital signal into an analog signal and an output circuit disposed downstream of the DA converting circuit. The output circuit outputs two selected color data signals and one black voltage based on the data state of one reference data signal, and outputs one fixed color data signal.

Abstract: Disclosed is a light emitting display apparatus. The light emitting display apparatus includes a plurality of pixels provided in a display area of a substrate and connected to a data line, a clock line, and a pixel driving power line. The plurality of pixels each include a pixel driving chip connected to the data line, the clock line, and the pixel driving power line to sequentially output a driving current through a plurality of output terminals thereof and a plurality of light emitting devices respectively connected to the plurality of output terminals, and the plurality of light emitting devices respectively and sequentially receive the driving current through the plurality of output terminals to emit light of different colors. Accordingly, light having a plurality of colors are respectively emitted in subfields of a unit frame, thereby preventing the occurrence of color breaking.
