Abstract: A display device includes a display panel including a display area and a non-display area adjacent to a side of the display area, and a residue trace disposed on the display panel, and disposed on the display area and the non-display area, wherein an outer boundary of the residue trace is adjacent to an edge portion of the display panel, and disposed to be closer to a center portion of the display panel than the edge portion of the display panel.

Abstract: A display device includes a main display area, and a first sub-display area and a second sub-display area around the main display area and located adjacent to each other, a plurality of pixel electrodes in the main display area and spaced from each other, a plurality of first sub-pixel electrodes in the first sub-display area and spaced from each other, a plurality of first copy pixel electrodes in the first sub-display area and connected to the first sub-pixel electrodes via a first bridge electrode, a first pixel defining layer in the main display area and the first sub-display area, and having a plurality of openings therein that overlaps the plurality of pixel electrodes, the plurality of first sub-pixel electrodes, and the plurality of first copy pixel electrodes, a plurality of second sub-pixel electrodes and second copy pixel electrodes in the second sub-display area and spaced from each other.

Abstract: Provided is an apparatus and method for transmitting and receiving a streaming service. An inter-arrival jitter may correspond to a delay variation in arrival time between TCP packets arriving at an apparatus for receiving the streaming service. The apparatus for receiving the streaming service may determine a de-jitter buffering time to absorb a network jitter before TS packets in a TCP packet is input to a T-STD buffer model. Based on the de-jitter buffering time, an initial playout delay lime at the apparatus for receiving the streaming service may be determined.

Abstract: Provided is an apparatus and method for transmitting and receiving a streaming service. The apparatus and method for transmitting and receiving a streaming service may use a light multimedia file suitable for a Hypertext Transfer Protocol (HTTP) streaming service. Using an HTTP hint track, an International Organization for Standardization (ISO) file generated in a non-interleaved storing scheme that is unsuitable for an HTTP streaming service may be converted into an ISO file based on an interleaved storing scheme that is suitable for an HTTP streaming service. An ISO file may include multiple media tracks for supporting multiple bitrates and resolutions. Chunk data of media tracks that provide multiple multimedia qualities may be effectively acquired, and a light ISO file suitable for an HTTP streaming service may be generated by storing the acquired chunk data in an interleaved scheme.

Abstract: An apparatus and method of producing polyurethane rubber bands. The apparatus includes a first device for heating and simultaneously drawing a polyurethane sheet produced by incising polyurethane tubular film obtained according to an inflation procedure, a second device for coating a release agent onto both sides of the drawn polyurethane sheet and drying the release agent-coated polyurethane sheet, a third device for longitudinally fine-cutting the dried polyurethane sheet using fine-cutting rollers to form several tens of strips of polyurethane rubber bands, depositing starch or talc powder on both sides of the polyurethane rubber bands, and heat-processing the polyurethane rubber bands deposited by the starch or talc powder, a fourth device for dispersing the heat-processed polyurethane rubber bands to impartially stuff the polyurethane rubber bands into packing receptacles, and a fifth device for heat-aging the packed polyurethane bands in an aging compartment.

Abstract: Disclosed is an apparatus and method of producing polyurethane rubber bands.
