摘要： A display device includes a timing controller configured to generate clock signals, a start signal, and image data. A scan driver includes a plurality of stages configured to sequentially output the clock signals as scan signals in response to the start signal. A data driver configured to generate a data signal based on the image data. A display unit includes pixels configured to emit light with luminance corresponding to the data signal in response to the scan signal. The timing controller is to mask at least one of the clock signals in a first section, a second section, and a third section included in one frame section and spaced from each other.

摘要： A display device includes a timing controller, a scan driver, a data driver, and a display unit. The timing controller generates a clock signal, a start signal, and image data. The scan driver includes a plurality of stages for sequentially outputting the clock signal as a scan signal in response to the start signal. The data driver generates a data signal using the image data. The display unit includes pixels for emitting light with a luminance corresponding to the data signal in response to the scan signal. The timing controller performs masking on the clock signal in a part of a first frame period during which the scan driver sequentially outputs the scan signal.

摘要： A display device is disclosed that includes a pixel component configured to output an image based on a first driving frequency, a scan driver configured to sequentially provide a scan signal to each pixel row in each frame based on the first driving frequency, and a driving controller configured control the scan driver such that, in the case where image data includes data corresponding to a static image, a display area is divided into a first area for the static image, and a second area for a video, and the first area is driven at a second driving frequency, and the second area is driven at a third driving frequency. The driving controller may control the scan driver such that a driving frequency corresponding to the first area is reduced to the second driving frequency, and a driving frequency corresponding to the second area is increased to the third driving frequency.
