The present invention relates to an apparatus that can easily adjust the angle and distance so that the viewing position of the display, such as a TV, a monitor, etc. produced using a flat panel display panel such as a PDP, LCD to a desired shape,

More specifically, the viewing angle of the fixed display can be finely adjusted to be the distance and distance desired by the viewer.

The present invention relates to a viewing position adjusting device for a display which can easily adjust the viewing angle of the elderly and the female, since the angle can be adjusted by a simple remote controller.

Flat panel displays such as plasma display panels (PDPs) and liquid crystal displays (LCDs) are popular because they are thinner and lighter than conventional CRT displays and occupy a small area so that they can be installed in a wall-mounted form. From monitors to TV monitors, they have almost replaced CRT displays.

One of the main reasons for the introduction of the angle adjusting means of the conventional flat panel display is to have a clear view when viewed from the front, but in order to solve the problem of color distortion and color inversion when viewing from a certain angle or more side, the viewing is possible from the front as possible. .

Mounting means for such a flat panel display includes a 'stand type device' for placing the display at a certain height on the ground, such as a rack such as a cabinet, and a 'wall type device' for attaching to a wall. It is implemented to adjust the distance and height.
