Abstract: A light emitting display device comprises a light reduction lens disposed in one or more pixel areas and disposed on light emitting diodes, and optionally, a light intensification lens disposed on other pixel areas and disposed on a color correction pattern. The light reduction lens increases omnidirectional reflection visibility of the light emitting display device and blocks hazardous blue light. The light intensification lens increases the luminance of blue light of the display device. Even if a uniformly distributed phase retardation film is applied, the light emitting display device with beneficial reflection characteristics, color gamut, and luminance is realized.

Abstract: An oral or nasal endotracheal tube includes a tube part, a first balloon and a second balloon. The tube part extends along a direction with a tube shape and an end portion of the tube part is intubated into trachea. The first balloon extends with passing through the tube part, and expands or contracts a block cuff. The second balloon extends with passing through the tube part, and expands or contracts a guide cuff. The block cuff uniformly expands around the tube part and blocks the trachea after the tube part is intubated into the trachea. The guide cuff ununiformly expands around the tube part and guides the tube part to be intubated into the trachea.
