Dependent claims

A rotatable display device comprising:

a display unit to display an image of an input signal of the rotatable display device;
a command input unit to input at least one adjustment command for the image;
a controller to receive the adjustment command to directly adjust a dimension of the image from a user and to change the adjustment command to another adjustment command according to a rotating direction of the display unit, when the display unit is rotated and the adjustment command is input, and to generate a first control signal to adjust the image on the display unit according to the changed another adjustment command;
an on-screen display (OSD) unit to generate an OSD message, wherein the OSD unit generates the OSD message in response to an OSD control signal generated by the controller when the adjustment command is input;
and
a pivot processor to rotate the displayed image according to the rotation direction of the display unit,
wherein the displayed image includes at least two images and the OSD message,
wherein adjusting the image on the display unit according to the changed another adjustment command comprises adjusting the at least two images and the OSD message according to the changed another adjustment command, when the adjustment command is input, and
wherein the pivot processor is enabled to separately rotate the at least two images and the OSD message.

#This application claims the priority of Korean Patent Application No. 2003-57996, filed on Aug. 21, 2003, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.

#1. Field of the Invention

#The present general inventive concept relates to a rotatable display device, and more particularly, to a rotatable display device and a method of adjusting an image on a display screen of the same according to a rotating direction of the display device.

Brief description of the drawings3 figures

#These and/or other aspects and advantages of the present general inventive concept will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:

#FIG. 1 shows a display screen of a rotatable display device rotated from a horizontal position to a vertical position;

#FIG. 2 is a schematic functional block diagram showing a rotatable display device according to an embodiment of the present general inventive concept; and

Detailed description2,855 words

#Reference will now be made in detail to the embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.

#FIG. 2 is a schematic functional block diagram showing a rotatable display device according to an embodiment of the present general inventive concept. The rotatable display device may include a command input unit 201, a controller 202, a first pivot processor 203, a format conversion unit 204, an on-screen display (OSD) generation unit 205, a second pivot processor 206, a drive unit 207, and a display unit 208.

#The command input unit 201 can allow a user to input an image adjustment command. The image adjustment command may include a command to increase/decrease a horizontal width or a vertical width of an image on a display screen, as well as a command to move a horizontal position or a vertical position of the image. The command to increase/decrease a size of the image and to move a position of the image can be performed using (+)/(−) keys (not shown).
