An organic light-emitting device includes: a first electrode; a second electrode opposite the first electrode; an emission layer between the first electrode and the second electrode; a hole transport region between the first electrode and the emission layer; and an electron transport region between the emission layer and the second electrode, the electron transport region including an electron control layer, wherein the hole transport region includes at least one compound selected from a first compound represented by Formula 1 and a second compound represented by Formula 2, and the electron control layer includes a third compound represented by Formula 3: 

Organic light-emitting device

An apparatus for line-alternating interpolation of chroma signals in a MUSE decoder for a high definition (HD) television can simultaneously transmit color difference signals such that a color difference signal of an untransmitted scanning line is restored using the color difference signal of a neighboring scanning line of a currently transmitting scanning line. In the apparatus, the color difference signals alternately inputting every scanning line through an input terminal, are delayed for periods of one horizontal line, so that the two signals which are most similar to the presently transmitting color difference signal among the delayed color difference signals are added together, and the two signals which are most dissimilar to the original signal are also added together. Therefore, more weight is given to the resultant sum of the similar signals to restore the untransmitted color difference signal, so that two color difference signals most similar to the original color are formed to be simultaneously transmitted.
