    Abstract: A display device comprises: a pixel-circuit layer comprising a pixel circuit and an auxiliary pixel circuit on a base layer; and a light-emitting-element layer comprising a light emitting element electrically connected to the pixel circuit. The pixel-circuit layer comprises a line part and an electrode part electrically connected to the line part. The light-emitting-element layer comprises an organic layer comprising a first region and a second region. In a plan view, the first region and the second region are spaced apart from each other with the electrode part interposed therebetween. The line part is electrically connected to the auxiliary pixel circuit.

    Abstract: A display device includes: a pixel connected to each of a first scan line, a second scan line, and a data line; a scan driver supplying a first scan signal to the first scan line and a second scan signal to the second scan line; a controller dividing one frame period into an active period and a blank period and generating a count signal in which a time duration of the blank period is counted and a power control signal; a data driver supplying a data signal to the data line; and a power supply controlling a source driving voltage supplied to the data driver according to a duration of the blank period based on the power control signal. When the count signal reaches a reference value, the controller supplies a start signal for output of the first scan signal to the scan driver.

    Abstract: A display device includes a display panel. The display panel includes a display panel including a data line, a sensing line, and pixels coupled to the data line and the sensing line. A timing controller generates clock embedded data including image data and a clock training signal. A data driver recovers a clock signal, based on the clock training signal of the clock embedded data, recovers the image data of the clock embedded data, based on the clock signal, supplies a data voltage corresponding to the image data to the data line in a first section, and receives a sensing signal from a pixel of the pixels through the sensing line in a second section different from the first section. In the second section, the data driver recovers the clock signal while the sensing signal is being received.
