Abstract: A display device includes a display panel including a plurality of display areas; a driving circuit to control the display panel; a timing controller to control the driving circuit to display an image on the display panel; a storage medium to store a plurality of weight tables respectively corresponding to the plurality of display areas; and a load value generator to generate a first load value corresponding to a first data unit of input image data, and to apply a weight to the first load value based on a first weight table corresponding to a display area in which the first data unit is to be displayed, among the plurality of weight tables. The timing controller controls the driving circuit with reference to a weighted first load value.

Abstract: A display apparatus includes a display panel, a gate driver, a data driver and a driving controller. The display panel is configured to display an image based on input image data. The gate driver is configured to output gate signals to gate lines of the display panel. The data driver is configured to output data voltages to data lines of the display panel. The driving controller includes a first compensation lookup table and a second compensation lookup table which are configured to compensate the input image data. The driving controller is configured to select one of the first compensation lookup table and the second compensation lookup table based on a first color shift and a second color shift and to apply the selected one of the first compensation lookup table and the second compensation lookup table to the input image data.

Abstract: A display device includes a first substrate including a plurality of pixel areas and a peripheral area disposed adjacent to the plurality of pixel areas. A second substrate faces the first substrate. A liquid crystal layer is disposed between the first substrate and the second substrate. A backlight unit provides light to the liquid crystal layer. A color conversion layer is disposed between the liquid crystal layer and the second substrate and includes a plurality of sub-color conversion units converting and emitting the light provided by the backlight unit into light of different predetermined colors. An optical sensor is disposed within the peripheral area. The optical sensor detects the light emitted from the plurality of sub-color conversion units and generates an optical signal corresponding thereto.
