ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an LCD screen device, more particularly to an LCD screen device which has an upright support for rotatably mounting an LCD screen unit about a horizontal axis perpendicular to the plane of the display face of LCD screen unit.
2. Description of the Related Art
Although conventional computer screens are supported adjustably by supports, they are only adjustable within a limited range substantially about a vertical axis relative to the supports. In addition, conventional computer screens have their longer dimension lying horizontally in order to have a wider view in a horizontal direction. They cannot be changed from a position where the longer dimension lies horizontally to a position where the longer dimension extends vertically so as to have a wider view in a vertical direction.
SUMMARY OF THE INVENTION
The main object of the present invention is to provide a rotatable LCD screen device including an LCD screen unit which can be rotated for placement in a first position where its longer dimension lies horizontally, or a second position where its longer dimension extends vertically.
According to this invention, a rotatable LCD screen device includes a substantially rectangular LCD screen unit which has a length and a width and which includes a front display side and a back side, and an upright support which is connected rotatably to the back side for rotation of the LCD screen unit about a horizontal axis substantially perpendicular to the plane of the front display side so as to place the LCD screen unit respectively in a first position where the length lies horizontally, and a second position where the length extends vertically. A lock mechanism is provided on the back side and the support for locking the LCD screen unit against movement relative to the support when the LCD screen unit is in the first position or the second position. In addition, a limiting mechanism is provided for limiting the angle of rotation of the LCD screen unit relative to the support.
