Abstract: An optical assembly for a projection system includes a light tunnel, a light tunnel holder that supports the light tunnel, an exterior casing that supports the light tunnel holder, a resilient member disposed between the light tunnel holder and the exterior casing to resiliently support the light tunnel holder, and an aligning unit that is disposed opposite the resilient member to align the light tunnel. The aligning unit can have at least one holder protrusion formed on an outer surface of the light tunnel holder, and a movable member that has a pressing protrusion for contact with the holder protrusion. The movable member slides on the outside of the light tunnel holder.

Abstract: A connector device and a display device using the same include an image displaying panel to display an image, a PCB to operate the image displaying panel, at least one cable port provided in the PCB, at least one cable connecter provided to be coupled to the cable port, and a connector holder disposed adjacent to the cable port to prevent the cable connector from being separated from the cable port. Thus the connector device and the display device using the same can prevent a cable mounted on a PCB from being separated therefrom.

Abstract: A display apparatus including a display main body displaying a picture, and a base supporting the display main body about an installation surface. The display apparatus further includes a tilting unit provided between the display main body and the base and allowing the display main body to be tilted about the base; a pivoting unit provided between the display main body and the tilting unit and allowing the display main body to be pivoted about the base; a lifting unit provided between the tilting unit and the base and allowing the display main body to move up and down about the base; and a swiveling unit coupled to the base and allowing the display main body to be swiveled about the installation surface. With this configuration, the present invention provides a display apparatus of which a display main body not only rotates about a base in various directions, but also moves up and down about the base.

Abstract: A display apparatus in which a monitor is firmly supported by a stand mounted with a hinge and is tilted at a predetermined angle. The display apparatus includes a monitor displaying a picture thereon, and a stand supporting the monitor. The stand includes a stand base, a hinge bracket placed on the stand base and formed with an opened hinge accommodating part at a side thereof, a hinge including a first part accommodated in and connected to the hinge accommodating part of the hinge bracket, a second part connected to a back of the monitor, and a tilt restrictor to restrict a tilt of the monitor; and a hinge bracket cover detachably coupled to the hinge accommodating part formed in the hinge bracket. The present invention provides a display apparatus improved in assembling efficiency and design.

Abstract: A display apparatus having: a display part displaying a picture; a base part supporting the display part; a tilting part provided between the display part and the base part and allowing the display part to be tilted relative to the base part, the tilting part including a tilting body combined to the base part, a tilting shaft rotatably combined to the tilting body, a tilting bracket having a first end combined to the display part and a second end combined to the tilting shaft, and an auxiliary bracket, spaced away from the tilting bracket, and having a first end combined to the display part and a second end combined to the tilting shaft. The display apparatus has a decreased packing volume by folding parallel with the base part, more stably supports a display part by having a reinforcing member, and conveniently swivels the display part relative to the base part.

Abstract: A display apparatus includes a display body having a display part, a supporting bracket attached to a wall and a angle control part connected to the supporting bracket to adjust a tilting angle of the display body. The display apparatus also includes a driving part to drive the angle control part to adjust the tilting angle of the display body, an input part for a user to adjust the tilting angle, an OSD generating part to generate an OSD signal to control the tilting angle, and a controller to control the driving part so that a tilting angle adjusting menu is displayed based on the OSD signal generated by the OSD generating part according to the input part, so that the tilting angle of the display body is adjusted according to a selection based on the tilting angle adjusting menu. Thus, the display apparatus may control the tilting angle of the display body minutely and easily by the OSD.
