Abstract: A data compensator includes a reference voltage drop generator, a voltage drop measurer, a compensation data generator, and an output block. The reference voltage drop generator generates reference voltage drops corresponding to R, G, and B data of a first pixel among the plurality of pixels. The voltage drop measurer calculates pixel voltage drops of the pixels based on R, G, and B data of the pixels and outputs a first pixel voltage drop of the first pixel. The compensation data generator generates R, G, and B compensation data compensating luminance distortion of the first pixel and color coordinate distortion of the first pixel based on a difference between the first pixel voltage drop and the reference voltage drops. The output block generates compensated R, G, and B data by adding the R, G, and B data of the first pixel and the R, G, and B compensation data, respectively.
