Abstract: An electronic device includes a display layer having pixels and configured to operate in units of one frame including a blank period and a data input period, and a sensor layer disposed on the display layer, and configured to sense a first type input and a second type input different from the first type input, wherein the sensor layer may be driven to sense the first type input and the second type input in the blank period, and, in one frame, a number of times that the second type input is sensed may be greater than a number of times that the first type input is sensed.

Abstract: A display panel includes a light emitting element and a pixel circuit electrically connected to the light emitting element. The pixel circuit includes a transistor. The transistor includes a first gate, an oxide semiconductor member overlapping the first gate, and a second gate overlaps the oxide semiconductor member. The oxide semiconductor member is disposed between the first gate and the second gate and includes a first semiconductor layer and a second semiconductor layer. The second semiconductor layer is disposed between the first semiconductor layer and the second gate in a thickness direction of the oxide semiconductor member. An atomic percent of oxygen of the first semiconductor layer is lower than an atomic percent of oxygen of the second semiconductor layer.
