  • Patent number: 10438527
    Abstract: A display device includes a display panel including a plurality of pixels arranged in a pentile pattern, the plurality of pixels having at least a first pixel and a second pixel adjacent to the first pixel, and the display panel being configured to display colors corresponding to respective output color data of the first and second pixels, and a color data converter configured to convert input color data to generate the output color data, the color data converter including a determiner configured to receive the input color data, to determine whether the first pixel displays a white color and the second pixel displays a black color, and to generate a first determination signal based on a result of the determination, and an adjustment unit configured to adjust the output color data of the first or second pixel based on the first determination signal.

  • Patent number: 9613562
    Abstract: A display device includes a light sensor, a controller, a data driver, and a scan driver. The controller is configured to correct an input image signal based on an electrical signal output by the light sensor and an input image signal, the controller includes: a first color coordinate calculation unit configured to calculate a color coordinate of reflected light; a second color coordinate calculation unit configured to calculate a color coordinate of dark room output light for at least two grayscale value sections; a combination unit configured to combine the reflected light color coordinate and the dark room output light color coordinate together; and a gamma value setting unit configured to set a gamma value based on a deviation between the combination light color coordinate output by the combination unit and a reference color coordinate.
