Abstract: A display device includes: a data driver for supplying a data signal to each of a plurality of data lines; and a pixel unit including a plurality of sub-pixels. The pixel unit further includes one dummy data line disposed separate from a data line of a first column among the data lines. The data line of the first column is connected to sub-pixels disposed on odd-numbered pixel rows among sub-pixels disposed on a first pixel column, and is connected to sub-pixels disposed on even-numbered pixel rows among sub-pixels disposed on a third pixel column. The dummy data line is connected to sub-pixels disposed on the even-numbered pixel rows among the sub-pixels disposed on the first pixel column.

Abstract: 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 is 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.

Abstract: 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.
