  • Patent number: 10415134
    Abstract: Disclosed is a crucible that exhibits stable evaporation efficiency and durability with respect to Al, is used in an evaporation source of an electron-beam evaporator, and includes a storage unit, which includes a wall and a bottom and in which a deposition material is placed, and a wetting prevention unit that includes another wall, which is taller than the wall of the storage unit, and another bottom, and is combined with an exterior of the storage unit. The wetting prevention unit is provided so that only the wall of the storage unit is wet with Al, and accordingly, the lifespan of the crucible is lengthened. Further, contact with the ceramic material in order to prevent wetting is minimized, thereby preventing a reduction in the physical properties of the thin film due to the impurities mixed with the deposited Al.

  • Patent number: 10319328
    Abstract: A display device and method is provided that permits selection of a first lookup table or a second lookup table to operate the data driver at respectively different temperatures to prevent heat from damaging the display device. The display device includes a detector which detects the number of toggles in which the amount of change in gray values of successive pixels driven by the same data line in one frame is equal to or greater than a reference gray change amount. A comparator compares the number of toggles detected by the detector with a reference number of toggles, and a lookup table selector which selects any one of a first lookup table and a second lookup table based on the comparison result of the comparator and provides the selected first lookup table or second lookup table to a data driver.
