Abstract

The purpose of the present invention is to provide an electronic display device capable of displaying content written horizontally and written vertically in an electronic display device with a plurality of display screens. The electronic display device includes a plurality of display screens that are bound and can be opened like a book, content storage unit 25 for storing content to be displayed on the display screens, content reading unit 27 for reading the content from the content storage unit, opening direction recognizing unit 29 for recognizing a first opening direction or a second opening direction of the content on the display screen, and display control unit 31 for arranging and displaying the content based on the first opening direction or second opening direction of the content.

Claims

1. An electronic display device comprising:

a plurality of display screens that are bound like a book and can be opened in a two-page spread;

a memory unit for storing the content to be displayed on the display screens;

a reading unit for reading the content from the memory unit;

an opening-direction recognizing unit for recognizing a first opening direction or a second opening direction of the content on the display screens; and

a display control unit for arranging and displaying content based on the first opening direction or second opening direction of the content.

2. The electronic display device of claim 1, wherein the display screens comprise a first display screen to an nth display screen;

and

the display control unit arranges and displays content in ascending order from the first display screen in the first opening direction, and arranges and displays content in descending order from the nth display screen in the second opening direction.

3. The electronic display device of claim 1, wherein the display screens comprise a first display screen to an nth display screen;

and

the display control unit arranges and displays content in ascending order from the first display screen in both the first opening direction and the second opening direction, and reverses the top and bottom of the content in the first opening direction and the second opening direction.

4. The electronic device of claim 1, wherein the content includes attributes indicating the opening direction of the content in the display screen;

and

the opening-direction recognizing unit recognizes the opening direction of the content based on the attributes.

5. The electronic display device of claim 1, wherein the opening-direction recognizing unit receives the opening direction information indicating the opening direction of the content from the user.

6. A recording medium for storing content readable by the electronic display device of claim 1 and including attributes indicating the opening direction of the content in the display screen.

7. An electronic display method in an electronic display device including a plurality of display screens bound like a book and can be opened in a two-page spread, comprising:

a memory step of storing the content to be displayed on the display screens;

a reading step for reading the content stored in the memory step;

an opening-direction recognizing step for recognizing a first opening direction and a second opening direction of the content on the display screen; and

a display control step for arranging and displaying the content based on the first opening direction or second opening direction of the content.

8. An electronic display program executed by an electronic display device including a plurality of display screens bound like a book and can be opened in a two-page spread, wherein the functionalities of the electronic display device are provided by:

a memory unit for storing the content to be displayed on the display screens;

a reading unit for reading the content from the memory unit;

an opening-direction recognizing unit for recognizing a first opening direction or a second opening direction of the content on the display screens; and

a display control unit for arranging and displaying content based on the first opening direction or second opening direction of the content.
