    Abstract: An electronic device which includes a display layer that operates in a folded state or an unfolded state and has an active region including a folding region and a plurality of non-folding regions, a sensor layer, and a sensor driver that operates in a charging drive mode to transmit a charging signal to the sensor layer. The sensor layer includes a plurality of first electrodes, a plurality of second electrodes, a plurality of first auxiliary electrodes, and a plurality of second auxiliary electrodes. The sensor driver sequentially provides the charging signal to the plurality of first auxiliary electrodes in a first direction during the charging drive mode, and the number of times that the charging signal is provided in the folded state and the number of times that the charging signal is provided in the unfolded state are different from each other.

    Abstract: A display device includes a display panel including touch electrodes, and a touch driving circuit including a driving signal output unit that outputs a touch driving signal supplied to the touch electrodes and a touch control unit that controls the driving signal output unit. The touch control unit sets the touch driving signal to swing between a first voltage and a second voltage higher than the first voltage, set the touch driving signal to rise to a third voltage higher than the second voltage and then lower from the third voltage to the second voltage, during a rising edge period, and set the touch driving signal to fall to a fourth voltage lower than the first voltage and then rise from the fourth voltage to the first voltage, during a falling edge period.

    Abstract: A light-emitting device includes: a first electrode; a second electrode; m emission units between the first electrode and the second electrode; and m−1 charge generation layer(s), each located between two adjacent emission units, and including m−1 n-type charge generation layer(s) and m−1 p-type charge generation layer(s). The m emission units each include a hole transport region, an emission layer, and an electron transport region. A first hole transport region in a first emission unit closest to the first electrode may include a hole transfer layer and a hole injection layer and/or a hole transport layer. The hole transfer layer may be a single layer consisting of an electron-transporting compound including a phosphine oxide group (P═O), a phosphine sulfide group (P═S), a π electron-deficient nitrogen-containing C1-C60 cyclic group, or any combination thereof. A highest occupied molecular orbital (HOMO) energy level of the hole transfer layer may be about −6.0 eV to about −5.3 eV.

    Abstract: An electronic device includes: a display layer in which an active area and a peripheral area adjacent to the active area are defined, the display layer including a common electrode, a sensor layer disposed on the display layer and including a plurality of sensing electrodes and an antenna pattern, and a cover layer spaced apart from the sensor layer with the display layer therebetween, the cover layer having a conductivity. The peripheral area includes a first area and a second area spaced apart from the active area with the first area therebetween, and the common electrode is disposed in the active area and the first area and is spaced apart from the second area. When viewed in a plan view, a portion of the antenna pattern does not overlap the common electrode and overlaps the cover layer.
