Abstract: A display device includes a display panel, a timing controller, a first source driver, and a second source driver. The display panel includes a first pixel, a second pixel and a plurality of data lines included in a pixel column. A first data line is connected to the first pixel, and a second data line is connected to the second pixel. The timing controller generates a pattern inversion control signal by detecting a predetermined image pattern from input data. The first source driver is connected to the first and third data lines, and replaces a first channel data corresponding to the first data line with a third channel data corresponding to the third data line in response to the pattern inversion control signal. Similarly, the second source driver replaces a second channel data corresponding to the second data line with a fourth channel data corresponding to the fourth data line.

Abstract: A display device including a first substrate, a color conversion layer on the first substrate and containing a wavelength conversion material, a first conductive polarizer on the color conversion layer, and a timing controller electrically connected to the first conductive polarizer. The timing controller may measure a resistance of the first conductive polarizer to generate a compensation signal based on the measured resistance.
