  • Patent number: 9034141
    Abstract: A thin film forming apparatus and a thin film forming method using the same are disclosed. In one aspect, the thin film forming apparatus comprises a mask that includes a blocking portion and an opening. It also includes an etching source that jets an etching gas through the opening of the mask to etch a thin film according to a pattern. The mask includes a gas blower for blowing a gas around the opening so that the etching gas does not penetrate into a thin film area corresponding to the block portion. When the thin film forming apparatus is used, a normal residual area of a thin film may be safely preserved and patterning may be accurately performed. Thus, the quality of a product manufactured by using the thin film forming apparatus may be improved.

  • Publication number: 20150014661
    Abstract: A organic light emitting display device including a first substrate on which red, green, and blue pixels are formed, the red, green, and blue pixels display including a plurality of first electrodes disposed corresponding to the red, green, and blue pixels, respectively, a plurality of organic light emitting structures emitting white light disposed above the first electrodes, respectively, a plurality of second electrodes respectively disposed on the organic light emitting structures, and a plurality of secondary transparent electrodes disposed between the first electrodes and the organic light emitting structures. The secondary transparent electrodes have different thicknesses from each other by a printing process such that red light, green light, and blue light are respectively emitted by the red, green, and blue pixels when the white light causes resonance to occur between the first electrodes and the second electrodes.
