Abstract: A semiconductor device includes a substrate having one or more inner surfaces defining trenches that define an active pattern of the substrate, the trenches including a first trench and a second trench which have different widths, a device isolation layer on the substrate such that the device isolation layer at least partially fills the trenches, and a word line intersecting the active pattern. The device isolation layer includes a first isolation pattern covering a portion of the second trench, a second isolation pattern on the first isolation pattern and covering a remaining portion of the second trench, and a filling pattern filling the first trench under the word line. A top surface of the second isolation pattern is located at a higher level than a top surface of the filling pattern.

Abstract: An LED lighting device includes a first luminescent device, a second luminescent device, a first current controller and a second current controller. The first current controller is coupled in parallel with the first luminescent device and configured to operate according to a first current setting, a switch-on voltage and a switch-off voltage. The second current controller is coupled in series to the second luminescent device and configured to operate according to a second current setting. The first current setting, the second current setting, the switch-on voltage and the switch-off voltage are adjusted by setting the mode selection pins of the first and second current controllers.

Abstract: A display window assembly having a reduced thickness, which can be easily manufactured with increased yield. The display window assembly may be employed with portable electronic devices. The display window assembly may include a case including an engaging portion and a predetermined opening, the predetermined opening may be at least partially defined by opposing surfaces of the case and the engaging portion may protrude from at least one of the opposing surfaces of the case, a transparent member having a first surface and a second surface, a display device, a connecting mechanism arranged between the second surface of the transparent member and a first surface of the display device, the connecting mechanism attaching the transparent member to the display device, and a backlight unit (BLU) arranged on a second surface of the display device, opposite to the first surface, to project light to the display device.

Abstract: A display device which may include a bottom chassis receiving a display panel, at least one printed circuit board mounting parts for controlling the display panel, and a reinforcing chassis attached to the printed circuit board.

Abstract: A display with a window assembly includes a case unit with an opening and having a stepped part in at least one side of an edge of the opening; a window member having a first surface coupled with the stepped part; a display unit closely adhered on a first side to a second surface of the window member; a backlight unit provided on a second side of the display unit, so as to project light to the display unit, the backlight unit having a housing unit for enclosing the display unit, and closely adhered to at least one portion of the window member that is not closely adhered to the display unit; and an adhesion unit arranged between the backlight unit and the window member to adhere the backlight unit and the window member to each other.

Abstract: A display with a window assembly includes a display unit and a backlight unit on the a first side of the display unit. The backlight unit has a housing unit enclosing. at least a portion of the display unit, exposing a second side of the display unit. The housing unit has at least one protrusion protruding toward the exposed, second side of the display unit. A window member closely adheres to the housing unit and the exposed second side of the display unit, and is coupled with the protrusion. An adhesion unit is arranged between the window member and the housing unit of the backlight to adhere the window member to the housing unit. A case unit has an opening exposing the window member, and has a stepped part on an opening edge of the opening. The stepped part is coupled with the window member.
