  • Patent number: 10911734
    Abstract: A virtual reality display device that can include a first pixel array and a second pixel array. Pixels of the pixel arrays can have a response time that is less than 2 msec, where the response time for a pixel is a sum of a first amount of time for brightness of the pixel to rise from 10% of white luminance to 90% of white luminance and a second amount of time for response time to fall from 90% of white luminance to 10% of white luminance. Additionally, the first pixel array can be separated from the second pixel array by a gap, and a distance from a center of the first pixel array to a center of the second pixel array is between 58 mm to 72 mm.

  • Patent number: 10692957
    Abstract: Provided is an organic light emitting display device in which a protective layer covers an electrostatic discharging circuit to minimize a damage which may be generated while discharging static electricity. At least one driving element which is connected to a data line and a gate line is disposed on a substrate. The driving element is covered by a planarization layer and is connected to the organic light emitting diode disposed on the planarization layer. The electrostatic discharging circuit is electrically connected to the data line or the gate line and is covered by the protective layer to minimize damages which may be caused in the organic light emitting display device during the process of discharging static electricity through the electrostatic discharging circuit.

  • Publication number: 20120293857
    Abstract: Disclosed are an electrophoretic display device and a manufacturing method thereof, which can enhance display quality and manufacturing efficiency. The electrophoretic display device includes a plurality of partition walls, sealing materials, a display solvent, and a second substrate. The partition walls are formed at a first substrate, and respectively define a plurality of unit pixel regions. The sealing materials are formed on the partition walls. The display solvent includes a plurality of charged particles and a solvent, and is filled into the unit pixel regions. The second substrate is adhered to the sealing materials to seal the unit pixel regions.

  • Patent number: 6846913
    Abstract: Disclosed is an extract from Korean mistletoe KM-110, which is of immunity enhancement and activity against tumor metastasis and can be used as an adjuvant material for vaccines applicable for the induction of humoral and cell-mediated immunity. Also disclosed are its fractions, a protein fraction KM-AS, a lectin fraction KML-C, lectin components KML-IIU and KML-IIL, which both are further purified from lectin fraction KML-C, a protein KMHBP which is obtained through heparin binding chromatography eluting with NaCl from a fraction C-free AS which is a portion of the KM-AS free of KML-C, and a mixture KM of the KMHBP and the KML-C. They are revealed as to their roles in the humoral and cell-mediated immunity enhancement and antitumoral activity.
