    Abstract: An electronic device includes a display including a plurality of regions, a display driver integrated circuit configured to drive a first region of the display at a first driving frequency and drive a second region of the display at a second driving frequency according to a configuration of the display, and a processor configured to provide display data to the display driver integrated circuit. The processor identifies a driving frequency of a first screen to be output on the display in response to reception of a first input; and controls the display to output at least a portion of the first screen on a region, of the plurality of regions, driven at a driving frequency corresponding to the driving frequency of the first screen. The display optimizes driving frequency, thus reducing heating problems and resource waste in the electronic device.

    Abstract: A display device including a display panel and a display driving circuit to control the display panel are provided. The display driving circuit includes a light emitting control driver to input a light emitting signal for controlling the brightness of the display panel into the display panel. When a light emitting control signal including a plurality of pulses is input into the light emitting control driver to control the light emitting signal, and when the operating frequency of the light emitting control signal is changed, pulse widths corresponding to at least two pulses of pulses included in the light emitting control signal may be adjusted to differ from each other in a frame after the target time point to change the operating frequency.

    Abstract: In a method of manufacturing a semiconductor device, a first insulation layer and a first sacrificial layer are alternately and repeatedly formed on a substrate to form a mold layer. A sacrificial layer structure is formed on the mold layer to include an etch stop layer and a second sacrificial layer sequentially stacked. After forming a hard mask on the sacrificial layer structure, the sacrificial layer structure and the mold layer are etched by a dry etching process using the hard mask as an etching mask to form a channel hole exposing an upper surface of the substrate and form a recess on a sidewall of the second sacrificial layer adjacent to the channel hole. A memory channel structure is formed in the channel hole. The first sacrificial layer is replaced with a gate electrode.
