  • Patent number: 12020612
    Abstract: A display device includes a housing, a display panel inserted into or withdrawn from the housing. The display panel includes a first display area and a second display area adjacent to the first display area with a boundary line therebetween, a battery which provides a power to the display panel, and a processor which drives the first display area in a display mode, in which the display panel displays an image in a state in which the first display area is withdrawn from the housing and the second display area is inserted into the housing. The processor drives the second display area in a charging mode, in which the battery is charged, in a way such that an average of degradation degrees of second pixels included in the second display area is equal to an average of degradation degrees of first pixels included in the first display area.

  • Patent number: 8759798
    Abstract: According to the present invention, an ion implantation system capable of implanting ions into a large substrate and reducing a manufacturing cost, and an ion implantation method using the same may be provided. The ion implantation system includes a plurality of ion implantation assemblies arranged in a line, each ion implantation assembly to implant ions into a partial region of the substrate. This allows for a compact ion implantation system to implant ions into a very large substrate. The substrate moves through the ion implantation system in a first direction, turns around, and then moves back through the ion implantation system in a second and opposite direction, where ions are implanted into the substrate while the substrate is moving in both directions. The path in the first direction can be spaced-apart from the path in the second direction to allow for two substrates to be processed simultaneously.

  • Patent number: 7505155
    Abstract: An apparatus and method for inspecting polycrystalline silicon (Poly-Si) that illuminates light onto protrusions in the Poly-Si in order to determine a distance between them using intensity and reflection angle of reflected light. The Poly-Si inspection apparatus includes a light source that illuminates light, and a reflected light detector for receiving reflected light, wherein a distance between protrusions is measured by an incident angle of the light illuminated into the protrusion from the light source, a detection angle of the reflected light detector, and a wavelength of the detected reflected light.
