Abstract: An automatic repeat request (ARQ) method for use in a communication system is disclosed. The ARQ method constructs a first data block set including a plurality of data blocks using data received from an upper layer, and transmits the data blocks contained in the first data block set to a reception end. If a predetermined time elapses without receiving any acknowledgement (ACK) signal after transmitting a last data block among the plurality of data blocks, the ARQ method transmits at least one data block reconstructed by the data received from the upper layer to the reception end until receiving the acknowledgment (ACK) signal from the reception end.

Abstract: Provided is an organic EL device and fabrication method thereof that can prevent the performance of the organic EL layer and the TFT from being lowered in forming the cathode using an E-beam heating evaporation process. The organic EL device includes a substrate, an anode, an organic EL layer, a cathode, and a transparent electrode connected with the cathode to extract the cathode to an outside, and further includes an interconnection line connected to the transparent electrode, for discharging charges accumulated on the cathode outside the organic EL device. According to the present invention, since the charges generated on the cathode can be removed through the interconnection line, the underlying organic EL layer and the TFT can be prevented from being damaged, so that the device reliability can be enhanced.
