  • Publication number: 20240375960
    Abstract: A system and method for exfoliating a layer of exfoliated material from a source material and for stacking the exfoliated layers. The system including a first rotary device and a second rotary device. The first and second rotary devices each being selectively rotatable in a clockwise and counter clockwise directions. A flexible tape having an adhesive surface, the tape extending between the first and second rotary devices. A press roller operably connected to a frame and adapted to provide a biasing force in a first direction. A stage having a chuck for securing a source substrate containing source material, the stage is operably connected to a stage actuator for moving the stage between an initial position and a process position.

  • Patent number: 9741307
    Abstract: A display apparatus includes a timing controller for converting data values of black image signals to have one polarity with respect to a common voltage and for converting data values of low gray scale image signals to have one polarity with respect to the common voltage, a data driver for converting the image signals outputted from the timing controller into data voltages, and a plurality of pixels for receiving the data voltages in response to gate signals to display an image. The low gray scale image signals displays a gray scale equal to or less than a reference gray scale at a surrounding temperature lower than a reference temperature.
