Abstract: An organic light emitting diode includes a first electrode and a second electrode overlapping each other, an emission layer disposed between the first electrode and the second electrode, and a hole transport layer disposed between the first electrode and the emission layer, the hole transport layer having a refractive index in a range of 1.0 to 1.6, in which the organic light emitting diode has a microcavity structure between the first electrode and the second electrode.

Abstract: A touch sensor and an organic light-emitting display including the sensor are disclosed. In one embodiment, the touch sensor includes i) a substrate, ii) a sensing unit formed on or over the substrate and containing hydrogen ions, iii) a touch sensor active layer formed on or above the sensing unit and iv) a touch sensor source electrode and a touch sensor drain electrode that are electrically connected to the touch sensor active layer. The touch sensor further includes a protective layer covering the touch sensor source electrode and the touch sensor drain electrode, and an opposite electrode formed on the protective layer, wherein at least part of the opposite electrode is formed substantially directly above the touch sensor active layer.

Abstract: A thin film deposition apparatus for performing continuous deposition, and a mask unit and a crucible unit that are included in the thin film deposition apparatus. A thin film deposition apparatus includes a moving unit configured to move a substrate as a deposition target; a mask unit configured to selectively pass vapor of a deposition source toward the substrate; and a crucible unit including a plurality of crucibles accommodating the deposition source and proceeding along a circulation path passing through the mask unit.
