Abstract: A light-emitting device including an organic layer disposed between a first electrode and a second electrode, the organic layer comprising a fluorescent compound, wherein upon excitation, excitons in a 3n-π* excited state of the fluorescent compound migrate to a 1π-π* excited state of the fluorescent compound by reverse intersystem crossing with a Rate (rISC), and then undergo radiative transition to a ground state to emit light via fluorescence. The fluorescent compound is defined by a ratio of Rate (rISC) to Rate (IC) is 0.5 or greater. An electronic apparatus including the light-emitting device, and the fluorescent compound.

Abstract: A coding tool is provided to improve the compression performance of inter prediction and is used at the encoder/decoder side to adjust the correction of a motion vector based on a high level syntax. In addition, a method is provided for simply performing an integer sample search step of searching for an integer offset and a fractional sample refinement step of searching for a sub-pixel offset in relation to motion vector refinement among coding tools.

Abstract: A video decoding apparatus is provided for decoding pictures using inter-prediction. The video decoding apparatus includes a predictor that generates affine prediction samples for respective subblocks in a target block in a current picture to be decoded by performing affine motion prediction on a subblock-by-subblock basis using control point motion vectors which respectively correspond to corners of the target block. The predictor also modifies sample values of the affine prediction samples by executing a first coding tool, the first coding tool compensating for motion according to sample positions in each of the subblocks using the control point motion vectors.

Abstract: Disclosed is a method for signaling virtual boundary information and constraining an operation of an in-loop filter on a virtual boundary by using the signaled boundary information in order to prevent performance deterioration which may occur when applying the in-loop filter for a discontinuous boundary (or virtual boundary) depending on frame packing in an encoding/decoding of a 360-degree omnidirectional video.
