Abstract: A semiconductor device includes a substrate; a first electrode layer disposed over the substrate; an interlayer insulating layer having an opening that exposes the first electrode layer; an oxide semiconductor layer formed along a surface of the opening and connected to the first electrode layer; a gate insulating layer formed along a surface of the oxide semiconductor layer; a stacked structure including a first gate electrode layer, a first insulating layer, a second gate electrode layer, and a second insulating layer stacked in a vertical direction while filling a remaining space of the opening in which the oxide semiconductor layer and the gate insulating layer are formed; and a second electrode layer disposed over the stacked structure and the oxide semiconductor layer and connected to the oxide semiconductor layer.

Abstract: A lamp includes a vehicle position sensing unit for sensing a position of a forward vehicle. The lamp includes a plurality of lamp units for changing beam patterns by opening or closing a portion of a shield having a plate shape, a shield actuating unit actuating the shield to open or close the portion of the shield and an optical axis adjustment unit for changing a direction of irradiation of light by adjusting an optical axis of at least one of the plurality of lamp units. In particular, a control unit forms a shadow zone by controlling at least one of the shield actuating unit and the optical axis adjustment unit according to the sensed position of the forward vehicle.

Abstract: A semi-wide view display method and device using the same are provided with a semi-wide view function for arbitrarily converting an aspect ratio of a screen in a television. The method includes the steps of setting a display mode according to a user-selected aspect ratio of a television screen; receiving vertical and horizontal blanking pulses, controlling the width of the blanking pulse according to the display mode setting, and outputting the result; generating a television signal which is displayed on the screen and a blanking signal which is not displayed on the screen by inputting the generated blanking pulse; and displaying the television and the blanking signal to thereby control vertical/horizontal over-scanning and vertically lengthen a blanking period, in order to convert the aspect ratio of the displayed image.
