Abstract: A display device includes a circuit layer including emission pixel drivers, and data lines transferring data signals of the emission pixel drivers; a data driver generating the data signals of the emission pixel drivers; and a demultiplexer circuit electrically connected between the data driver and the data lines and including a first demultiplexer transistor turned on by a first demultiplexer control signal and a second demultiplexer transistor turned on by a second demultiplexer control signal. A first data line of the data lines is electrically connected to the data driver through the first demultiplexer transistor and a transfer path shorter than a first extension length. A second data line of the data lines is electrically connected to the data driver through the second demultiplexer transistor and a transfer path longer than or equal to the first extension length.

Abstract: Provided is an apparatus and method for encoding/decoding a moving picture based on adaptive scanning. The moving picture apparatus and method can increase a compression rate based on adaptive scanning by performing intra prediction onto blocks of a predetermined size, and scanning coefficients acquired from Discrete Cosine Transform (DCT) of a residue signal and quantization differently according to the intra prediction mode. The moving picture encoding apparatus includes: a mode selector for selecting and outputting a prediction mode; a predictor for predicting pixel values of pixels to be encoded of an input video based on the prediction mode to thereby output a residue signal block; a transform/quantization unit for performing DCT onto the residue signal block and quantizing the transformed residue signal block; and an encoder for adaptively scanning and encoding the quantized residue signal block based on the prediction mode.
