Abstract: An organic light emitting display apparatus includes a substrate including a plurality of pixels. The organic light emitting display apparatus further includes a plurality of organic light emitting diodes on the substrate so as to correspond to the plurality of pixels. The plurality of pixels includes a first pixel, a second pixel, a third pixel, and a fourth pixel which emit different color light. Each of the plurality of organic light emitting diodes includes a first electrode, a light emitting portion on the first electrode and a second electrode on the light emitting portion. A thickness of the first electrode of the first pixel is different from a thickness of the first electrode of the second pixel, and the thickness of the first electrode of the second pixel is different from a thickness of the first electrode of the third pixel.

Abstract: In embodiments, an electronic device may include a housing having an inner space, a printed circuit board (PCB) disposed in the inner space of the housing, a first antenna structure disposed at a position spaced apart from the PCB, and transmitting and/or receiving a radio signal in a first frequency band, at least one second antenna structure disposed at a position spaced apart from the PCB, and transmitting and/or receiving a radio signal in a second frequency band different from the first frequency band, and a flexible substrate electrically connecting the PCB and the first antenna structure.

Abstract: Disclosed herein is a washing machine and a control method thereof, and more particularly, to a technology capable of controlling washing modes in various manners by manipulating a control panel of the washing machine. The washing machine includes a display configured to display a washing mode, an inputter configured to receive a washing mode select command, a storage configured to store a selected washing mode, and a controller configured to allow a washing mode, which has the largest number of times selected during a predetermined number of times of washings, to be displayed on a first screen of the display, and in response to the number of the washing mode having the largest number of selection times being plural, configured to allow a washing mode, which is the last selected among the plurality of washing modes, to be displayed on the first screen of the display.

Abstract: A semiconductor device including a first contact plug structure on a substrate, a lower spacer structure on a sidewall of the first contact plug structure, and a bit line structure on the first contact plug structure and including a conductive structure and an insulation structure stacked in a vertical direction substantially perpendicular to an upper surface of the substrate may be provided. The first contact plug structure may include a conductive pad contacting the upper surface of the substrate, an ohmic contact pattern on the conductive pad, and a conductive filling pattern on the ohmic contact pattern. The conductive filling pattern may include metal, and include a lower portion having a relatively large width and an upper portion having a relatively small width. The lower spacer structure may contact a sidewall of the conductive filling pattern.

Abstract: It is provided a novel LLC resonant converter with high reliability and the operation method thereof. The LLC resonant converter proposed in the present invention includes an original converter including a primary side circuit on which two half-bridge cells are connected in parallel and a secondary side circuit on which two half-bridge cells are connected in series and a redundant converter having the same configuration with the original converter, and connected with the original converter at a midpoint of a secondary winding.

Abstract: The composite input device includes a first detector configured to detect a rotating operation, a second detector configured to detect a tilting operation, and a substrate disposed perpendicular to a rotational axis of the rotating operation. In a plan view in a direction perpendicular to the substrate, the first detector is disposed inside an imaginary circle. The imaginary circle has a center at an intersection of the substrate and an the rotational axis of the rotating operation and has an outer circumference that passes through an outer edge of the second detector positioned farthest away from the center of the imaginary circle.
