Abstract

A digital book includes a casing adapted to fold open and shut like a book and having a folding axis, a main part, and a secondary part, together forming a book back part. A display unit consists of at least two parts arranged such that when the casing is folded out, the main part and the secondary part are each presented with at least one screen each, like pages of a book. A control unit has means for receiving, storing, processing, and reproducing information, and an operating unit has operating elements for using the digital book as a device for receiving/processing/reproducing information. A supply unit has a receiving opening and a guide and supply pin, by means of which the digital book can be plugged in when the casing is folded shut, for inputting and outputting information, for supplying energy, and for storing the digital book.

Claims

1. A display device for displaying text or image information, comprising:

a casing comprising a first part and at least one second part, wherein said first part and said at least one second part are arranged such that said casing can be folded open and shut about a folding axis like a book, wherein a spine part is formed by said first part and said at least one second part by a slidable coupling of said first part and said at least one second part, wherein said slidable coupling mechanically and electrically couples said first part and said at least one second part, and wherein said spine part is adapted to accommodate a battery for current supply, and

a display unit with at least one display, wherein said first part comprises said display unit,

wherein said at least one second part comprises an input unit for inputting or manipulating data, and wherein said input unit comprises an alphanumeric keyboard.

2. The display device of claim 1, wherein said display device further comprises a control unit for receiving, storing, processing, or reproducing information.

3. The display device of claim 1, wherein said display device further comprises at least one operator unit with operator elements for using said display device as an information receiving, processing, or reproducing device.

4. The display device of claim 1, wherein said casing comprises counter contacts in a guide and a supply opening for supplying power or for inputting and outputting information.

5. The display device of claim 4, further comprising a supply unit comprising a receiving opening and a pin, wherein said receiving open receives said casing and said guide and supply opening receives said pin.

6. The display device of claim 4, wherein said guide and supply opening comprises a cylindrical shape such that a longitudinal axis of said guide and supply opening lies coaxially to said folding axis.

7. The display device of claim 1, wherein said first part and said at least one second part are firmly connected to each other.

8. The display device of claim 1, wherein said display device displays text and image information.

9. The display device of claim 1, wherein said battery is a rechargeable battery.

10. The display device of claim 1, wherein said input unit is configured for inputting and manipulating data.

11. The display device of claim 10, wherein said guide and supply opening comprises a cylindrical shape such that a longitudinal axis of said guide and supply opening lies coaxially to said folding axis.

12. The display device of claim 1, wherein said input unit comprises a touch screen display.

13. The display device of claim 12, wherein said casing further comprises a holding means for receiving a screen pen configured for interacting with said touch screen.

14. The display device of claim 1, wherein said casing further comprises a third part, wherein said third part and said at least one second part are arranged such that said casing can be folded open and shut about a second folding axis.

15. The display device of claim 1, wherein said alphanumeric keyboard is a laptop keyboard.

16. The display device of claim 1, wherein said first part and said at least one second part are removably coupled together.

18. The display device of claim 1, wherein said display unit is flexible.

19. A display device for displaying text or image information, comprising:

a casing comprising a first part and at least one second part, wherein said first part and said at least one second part are arranged such that said casing can be folded open and shut about a folding axis like a book, wherein a spine part is formed by said first part and said at least one second part by a slidable coupling of said first part and said at least one second part, wherein said slidable coupling mechanically and electrically couples said first part and said at least one second part, and wherein said spine part is adapted to accommodate a battery for current supply, and

a display unit with at least one display, wherein said first part comprises said display unit,

wherein said at least one second part comprises an input unit for inputting or manipulating data, wherein said display unit and said input unit are arranged such that, in a folded open state of said casing, said display unit and said input unit are presented to a user like pages of a book, and wherein said input unit comprises an alphanumeric keyboard.

20. The display device of claim 19, wherein said display device further comprises a control unit for receiving, storing, processing, or reproducing information.

21. The display device of claim 19, wherein said display device further comprises at least one operator unit with operator elements for using said display device as an information receiving, processing, or reproducing device.
