Abstract

The present application relates to a display mode switching device and method for a portable electronic device. In particular, the present application relates to a portable electronic device that can switch display modes of an integrated display and input device to facilitate composition of a text message by switching between a portrait mode and a landscape mode. A portable electronic device may use a display mode switching method in which a posture of the portable electronic device can be checked, and a display mode can be selected based on the posture. A portrait-mode text messaging composition window with a portrait-mode key map and a landscape-mode text messaging composition window with a landscape-mode key map can be displayed in the selected display mode.

Claims

1. A display method of an electronic device, the method comprising:

detecting an orientation of the electronic device; and

displaying, on a single display screen of the electronic device,

an input region configured to display a plurality of virtual keys according to one of a first key map corresponding to a first orientation of the electronic device and a second key map corresponding to a second orientation of the electronic device, in response to the detected orientation of the electronic device, and

an output region configured to display characters input via the virtual keys,

wherein the second key map corresponding to the second orientation of the electronic device includes a left-side group of virtual keys and a right-side group of virtual keys that are respectively arranged at left and right sides of the single display screen.

2. The method of claim 1, wherein the first orientation of the electronic device corresponds to a portrait orientation, and the second orientation of the electronic device corresponds to a landscape orientation.

3. The method of claim 1, wherein a key size of each key included in the first key map is larger than a key size of each corresponding key included in the second key map.

4. The method of claim 1, wherein each virtual key of the plurality of virtual keys includes at least one character.

5. The method of claim 4, wherein a font size of the at least one character included in each virtual key of the plurality of virtual keys is different depending on the detected orientation of the electronic device.

6. The method of claim 1, further comprising:

adjusting a number of characters per line displayed in the output region according to the detected orientation of the electronic device.

7. An electronic device, comprising:

a display;

an orientation detector configured to detect an orientation of the electronic device; and

a processor configured to control the display to display, on a single display screen,

an input region configured to display a plurality of virtual keys according to one of a first key map corresponding to a first orientation of the electronic device and a second key map corresponding to a second orientation of the electronic device, in response to a detected orientation of the electronic device, and

an output region configured to display characters input via the virtual keys,

wherein the second key map corresponding to the second orientation of the electronic device includes a left-side group of virtual keys and a right-side group of virtual keys that are respectively arranged at left and right sides of the single display screen.

8. The electronic device of claim 7, wherein the first orientation of the electronic device corresponds to a portrait orientation, and the second orientation of the electronic device corresponds to a landscape orientation.

9. The electronic device of claim 7, wherein a key size of each key included in the first key map is larger than a key size of each corresponding key included in the second key map.

10. The electronic device of claim 7, wherein each virtual key of the plurality of virtual keys includes at least one character.

11. The electronic device of claim 10, wherein a font size of the at least one character included in each virtual key of the plurality of virtual keys is different depending on the detected orientation of the electronic device.

12. The electronic device of claim 7, wherein the processor is further configured to control the display to adjust a number of characters per line displayed in the output region according to the detected orientation of the electronic device.
