Abstract

A display apparatus and method for use in a wireless terminal are provided. A direction signal is sensed according to a position in which the wireless terminal is placed. A case when no direction signal is sensed is determined as a first direction signal, and display data is output and displayed in a standard direction. When the sensed direction signal is a second direction signal, the display data is rotated by 90°, the rotated display data is compressed, and the compressed rotated display data is displayed. When the sensed direction signal is a third direction signal, the display data is rotated by 180°, and the rotated display data is displayed. When the sensed direction signal is a fourth direction signal, the display data is rotated by 270°, the rotated display data is compressed, and the compressed rotated display data is displayed.

Claims

1. A display apparatus for use in a wireless terminal, comprising:

a direction sensing unit for sensing a direction according to a position in which the wireless terminal is placed, and generating first to fourth direction sensing signals;

a control unit for outputting display data in a standard direction when the first direction sensing signal is generated, outputting the display data rotated by 90° and

compressed when the second direction sensing signal is generated, outputting the display data rotated by 180°

when the third direction sensing signal is generated, and outputting the display data rotated by 270° and

compressed when the fourth direction sensing signal is generated;

a memory unit comprising;

a first picture buffer for storing a value indicating a size of a first picture displaying the display data when the first and third direction sensing signals are generated, and

a second picture buffer for storing a value indicating a size of a second picture displaying the display data when the second and fourth direction sensing signals are generated; and

a display unit for displaying the display data.

2. The display apparatus according to claim 1, wherein the memory unit comprises:

the first picture buffer for storing start and end position information of the first picture size; and

the second picture buffer for storing a start position and an end position information of the second picture size.

3. The display apparatus according to claim 1, wherein the memory unit comprises:

a first text buffer for storing a value indicating a size of a first font to be displayed when the first and third direction sensing signals are generated; and

a second text buffer for storing a value indicating a size of a second font to be displayed when the second and fourth direction sensing signals are generated.

4. A display method for use in a wireless terminal, comprising:

sensing a direction signal according to a position in which the wireless terminal is placed;

determining, as a first direction signal, a case when no direction signal is sensed, and outputting and displaying display data in a standard direction;

rotating the display data by 90°

, compressing the rotated display data, and displaying the compressed rotated display data, when the sensed direction signal is a second direction signal;

rotating the display data by 180°

, and displaying the rotated display data, when the sensed direction signal is a third direction signal; and

rotating the display data by 270°

, compressing the rotated display data, and displaying the compressed rotated display data, when the sensed direction signal is a fourth direction signal.

5. The display method according to claim 4, wherein outputting and displaying the display data in the standard direction comprise:

rotating the display data by 0°

; and

displaying the display data rotated by 0°

in a first picture size.

6. The display method according to claim 5, wherein displaying comprises:

displaying the display data in a first font size.

7. The display method according to claim 4, wherein displaying the display data when the sensed direction signal is the second direction signal comprises:

rotating the display data by 90°

;

compressing the display data rotated by 90°

into a second picture size; and

displaying the compressed display data.

8. The display method according to claim 7, wherein displaying comprises:

displaying the compressed display data in a second font size.

9. The display method according to claim 4, wherein displaying the display data when the sensed direction signal is the third direction signal comprises:

rotating the display data by 180°

; and

displaying the display data rotated by 180°

in a first picture size.

10. The display method according to claim 9, wherein displaying comprises:

displaying the compressed display data in a first font size.

11. The display method according to claim 4, wherein displaying the display data when the sensed direction signal is the fourth direction signal comprises:

rotating the display data by 270°

;

compressing the display data rotated by 270°

into a second picture size; and

displaying the compressed display data.

12. The display method according to claim 11, wherein displaying comprises:

displaying the compressed display data in a second font size.

13. An apparatus for directionally displaying images on a screen, comprising:

the screen and a magnet disposed in a folder;

a plurality of sensors disposed in a base for detecting the position of the folder, said base and folder being pivotally connected via a connector; and

a controller for receiving directional signals from the plurality of sensors indicative of the position of the folder and displaying images in an upright position relative to the position of the folder.

14. The apparatus of claim 13, wherein the positions of the folder comprise 0 degree, 90 degrees, 180 degrees, and 270 degrees.

15. The apparatus of claim 13, wherein the controller compresses image data and reduces a font size of data for display on the screen when the folder is rotated at 90 degrees or 270 degrees.

16. The apparatus of claim 13, wherein the image on the screen is rotated an equal but opposite angle from the rotation of the folder to maintain the image on the screen in an upright position relative to the position of the folder.

17. The apparatus of claim 14, wherein the 0 degree position of the folder comprises a standard direction for viewing the screen.

18. The apparatus of claim 13, further comprising:

a camera for capturing at least one of still images and moving images.

19. The apparatus of claim 13, further comprising:

a memory for storing image data and text data.
