A display device includes a driving control circuit that receives an input image signal and outputs an output image signal, a data driving circuit that outputs a data signal corresponding to the output image signal, and a display panel including a plurality of pixels to display an image corresponding to the data signal. The driving control circuit determines an amount of time the input image signal is maintained as a still image, determines a color coordinate gain based on the amount of time and outputs the output image signal based on the color coordinate gain.

Display device and operation method thereof

A display device is disclosed that includes a display panel including a plurality of pixels, a printed circuit board connected to the display panel, a temperature sensor disposed on the printed circuit board, a flexible circuit board that connects the display panel to the printed circuit board, a data driver disposed on the flexible circuit board, and a temperature sensing part disposed on the printed circuit board. The flexible circuit board is bent such that the printed circuit board is disposed under the display panel and the temperature sensor is disposed adjacent to a sensing pixel outputting a sensing current among the pixels.

Display device including sensing pixel on display panel and temperature sensor on printed circuit board, and driving method thereof

A display device includes: a display panel including a first display area and a second display area; and a panel driving block which provides, to the first display area, a first data signal generated by converting a first image signal, which corresponds to the first display area, based on a first reference color coordinates in a color space, and provides, to the second display area, a second data signal generated by converting a second image signal, which corresponds to the second display area, based on second reference color coordinates in the color space. The second reference color coordinates are color coordinates obtained by shifting the first reference color coordinates in the color space.
