A ceiling-mounted air conditioner is provided. The ceiling-mounted air conditioner includes a main body which is fixed onto a ceiling of a room where the ceiling-mounted air conditioner is installed and includes an air intake formed at the bottom thereof; a door panel which is connected to the bottom of the main body so as to be able to be attached to or detached from the main body and shuts or opens the air intake by being lifted up or down; a plurality of moving elements which are fixed onto the top surface of the door panel, are a predetermined distance apart from one another, and are lifted up or down so as to be able to lift up or down the door panel; and a plurality of rotation elements which are disposed at the main body so as to be able to rotate and thus to lift up or down the moving elements, wherein each of the moving elements includes a vertical portion having a cavity portion extending vertically therein and protruding vertically from the top surface of the door panel, a driving force transmitting portion formed on one side of the cavity portion and contacting a corresponding rotation element, and an elevation guide portion formed on the other side of the cavity portion and guiding the elevation of the vertical portion. Therefore, it is possible to improve the exterior appearance of the ceiling-mounted air conditioner.

There is provided an optical pickup actuator for actuating a lens holder having an object lens according to an interaction between coils and magnets. The optical pickup actuator includes a lens-seating portion formed on the lens holder to support the object lens and a lens guide portion protruding from the lens-seating portion to securely support the object lens. The lens guide portion has an adhesive confining groove in which adhesive can be injected to securely fix the object lens.

Optical pickup actuator

A system for improving the resolution of a display device by using human visual characteristics wherein an image can be displayed at a more improved resolution than an actual physical resolution, thereby achieving the same effect as that where the resolution is physically improved. An image signal corresponding to one frame is separated into a first image signal and a second image signal, and a first image and a second image are formed based on the first image signal and the second image signal. The first image and the second image are respectively displayed at a first location and a second location. As a result, a viewer can view the image with an improved resolution.

Display device for improving an image resolution of projection-type display device

An optical pick-up actuator is provided. The optical pick-up actuator includes a lens holder, a tracking coil, a focusing coil, and a magnet. The lens holder holds an objective lens. The tracking coil is wound with wire, is disposed at a central portion on both sides of the lens holder, and includes a horizontal width at a top thereof that is less than a horizontal width at a bottom thereof. The focusing coil is wound with wire, is disposed at a left and a right on both sides of the lens holder, and includes a horizontal width at a top thereof that is greater than a horizontal width at a bottom thereof. The magnet faces the tracking coil and the focusing coil.

A concept of improving a resolution by using human's visual characteristics is provided. Bu the present invention, an image can be displayed at a more improved resolution than an actual physical resolution, thereby obtaining the same effect that the resolution is physically improved. An image signal corresponding to one frame is split into a first image signal and a second image signal, and a first image and a second image are formed based on the first image signal and the second image signal. Then, the first image and the second image are respectively displayed at a first location and a second location. As a result, a viewer can view the image at an improved resolution.
