Abstract: A display device includes a display layer, a plurality of touch electrodes, a light shield, and a code pattern. The display layer includes a plurality of light emission areas for emitting light. The plurality of touch electrodes are disposed on the display layer to sense a touch and surround the plurality of light emission areas. The light-shield is disposed on a portion of the plurality of touch electrodes. The code pattern is determined by a planar shape of the light-shield to have position information. The light-shield absorbs light of a specific wavelength, and another portion of the touch electrodes, which is not overlapped with the light-shield, reflects light of the specific wavelength.

Abstract: A display device and a driving method thereof. The display device includes a color controller configured to generate second image data by converting the color gamut of first image data received from the outside and to generate third image data by correcting the first image data or the second image data depending on the viewing angle variation between the first image data and the second image data, and a display panel configured to display an image based on the second image data or the third image data.
