Abstract: Disclosed are an inter-prediction method and an image decoding apparatus using the same. According to an embodiment of the present invention, there is provided an inter-prediction method including extracting a merge candidate flag and offset information from a bitstream, selecting a merge candidate corresponding to the extracted merge candidate flag from a merge candidate list including neighboring blocks of a current block as merge candidates, deciding a motion vector of the current block by applying the offset information to a motion vector of the selected merge candidate, and generating, as a prediction block of the current block, a block indicated by the motion vector of the current block in a reference picture referenced by the selected merge candidate.

Abstract: A method is disclosed for reconstructing a current block in units of sub-blocks included in the current block. The method includes: decoding transform coefficients in a transform block of the current block, sub-block information indicating a division form of the sub-blocks and transform type information indicating a transform type applied to the transform block from a bitstream; deriving a residual block of the current block from the transform coefficients on the basis of the transform type indicated by the transform type information and the sub-block information; and filtering boundaries of the sub-blocks in a reconstructed block of the current block derived on the basis of the residual block.

Abstract: Disclosed herein are an OLED display panel further including a switching transistor for controlling application of supply voltage in the initializing interval of a pixel, an OLED display device including the same, and a method for driving the same. The OLED display panel avoids a short-circuit between supply voltage VDD_EL and reference voltage Vref to thereby reduce initialization voltage applied to the gate terminal of the driving transistor T_dr. The OLED display device can achieve various effects such as improved response characteristics of pixels by reducing deviation in the initial voltage used in sampling.
