Abstract: An organic electroluminescence (EL) display panel includes a substrate, a thin film transistor on the substrate, an overcoat layer on the thin film transistor and containing an organic material, a first electrode on the overcoat layer, an organic light emitting layer on the first electrode, a second electrode on the organic light emitting layer, and a barrier layer between the overcoat layer and the first electrode and including a first region formed of a single layer and a second region formed of a multilayer.

Abstract: A light emitting structure includes a first hole injection layer, a first organic light emitting layer, a charge generation layer, a second hole injection layer, a second organic light emitting layer, an electron transfer layer, and a blocking member. The light emitting structure has first, second, and third sub-pixel regions. The first organic light emitting layer may be on the first hole injection layer. The charge generation layer may be on the first organic light emitting layer. The second hole injection layer may be on the charge generation layer. The second organic light emitting layer may be on the second hole injection layer. The electron transfer layer may be on the second organic light emitting layer. The blocking member may be at at least one of the first to the third sub-pixel regions.

Abstract: An organic light-emitting display apparatus that has reduced resonance effect includes a thin film transistor (TFT) layer including a plurality of TFTs, first protective layer covering the TFT, a color filter disposed in at least a partial area of the region in the first protective layer, a first overcoat covering the color filter, a second protective layer covering the first overcoat, a second overcoat disposed on the second protective layer, and a pixel electrode disposed on top of the second overcoat and electrically coupled to the TFTs in the TFT layer.

Abstract: A method and apparatus of controlling failure of a Motor-Driven Power Steering (MDPS) system may include monitoring a first torque sensor signal and a second torque sensor signal detected by a torque sensor, performing a safety mode operation in which control of the MDPS may be performed such that when a fault signal of the first torque sensor signal or the second torque sensor signal may be detected, the MDPS may be controlled to decrease a steering assist power, and performing a manual mode operation in which control of the MDPS may be performed such that when a fault signal of a remaining torque sensor signal out of the first and second torque sensor signals, which was not detected during the safety mode operation, may be detected, the MDPS may be controlled to completely lose the steering assist power.
