Abstract: A display panel including a first edge extending in a first direction, a second edge extending in a second direction intersecting with the first direction, and a corner edge extending in a curved shape from the first edge to the second edge includes: a substrate including a front area overlapping a center of the display panel and a corner area extending from the front area to the corner edge; and a pixel arranged over the substrate, wherein the display panel is curved in the corner area in a direction in which the corner edge approaches the center of the display panel.

Abstract: An electronic device includes a light source, a light sensor, and a controller that senses an amount of a coarse ambient light by turning off the light source and performing sensing in a coarse mode by using the light sensor and senses an amount of a fine ambient light by performing sensing in a fine mode by using the light sensor. The controller senses an amount of a target light by turning on the light source and performing sensing by using the light sensor while the light source emits a light, and outputs information based on the amount of the coarse ambient light, the amount of the fine ambient light, and the amount of the target light.

Abstract: A memory controller of inventive concepts may include an active regulator configured to operate in an active mode and be inactive in a sleep mode, an active logic configured to receive a drive voltage, a power gating switch configured to connect the active regulator to the active logic after a transient state of the active mode, the transient state being an initial time period of the active mode, and a charging circuit configured to charge the active logic during the transient state.
