Abstract: Disclosed is a method of processing item sales information in an electronic apparatus, the method including receiving a transaction request for at least one item including a transaction method and transaction amount information, providing, when the transaction method is a specific type of transaction method and a time in which the transaction request is received is included in a time section or within a time period corresponding to the transaction method, a transaction response including approval information corresponding to the transaction request before payment information corresponding to the transaction request is received from a first server corresponding to the transaction method, transmitting a shipping request for at least a portion of the at least one item to a second server, and transmitting a payment request to the first server in response to the time section or the time period ending.

Abstract: Provided is a method of providing a payment service according to various example embodiments. The method of providing a payment service may include acquiring a payment request for an item from a user, identifying whether the acquired payment request satisfies designated conditions, and omitting an additional authentication operation in response to the payment request satisfying the designated conditions and providing payment completion information corresponding to the payment request. Other example embodiments are possible.

Abstract: An organic light emitting diode display includes a substrate including a light transmitting area which is at a display area for displaying an image, and an emission area which is adjacent the light transmitting area, an organic light emitting diode on the substrate at a location corresponding to the emission area; and a light control unit on the substrate at a location corresponding to the light transmitting area and configured to control transmission of light.

Abstract: An organic light emitting device includes an anode, a cathode, and an organic layer between the anode and the cathode, wherein the organic layer includes an emission layer, an electron transport layer, and an assistance layer interposed therebetween, and the assistance layer has a higher HOMO level than the electron transport layer by more than 0.3 eV. The accumulation of holes in the electron transport layer is decreased or prevented by the gap of the HOMO level between the assistance layer and the electron transport layer such that the lifetime of the organic light emitting device may be increased.

Abstract: An organic light emitting display apparatus including a plurality of sub-pixels disposed on a substrate, wherein each of the sub-pixels includes: a first electrode formed on the substrate; an intermediate layer formed on the first electrode and including an organic emission layer; and a second electrode formed on the intermediate layer, wherein at least one sub-pixel for emitting light of a color among the sub-pixels includes a shadow emission layer for emitting light of different color between the organic emission layer and the first electrode, and the organic emission layer of the one sub-pixel includes a hole transport material.
