Abstract

A digital television including a display unit configured to display a keypad including a plurality of key buttons which are assigned with different alphabet characters, respectively, and a text window; and a controller configured to receive a first signal selecting a first key button of the plurality of key buttons, display a first alphabet character assigned with the first key button in the text window, and display a first sub key button assigned with a second alphabet character on a first region adjacent to the first key button of the keypad, in response to the first signal, and receive a second signal selecting the first sub key button, and display the second alphabet character next to the first alphabet character in the text window, and display a second sub key button assigned with a third alphabet character on the first region adjacent to the first key button of the keypad, in response to the second signal. The second alphabet character is predicted as a next character of the first alphabet character, and the third alphabet character is predicted as a next character of the first and second alphabet characters.

Claims

1. A digital television comprising:

a display unit configured to display a keypad including a plurality of key buttons which are assigned with different alphabet characters, respectively, and a text window; and

a controller configured to;

receive a first signal selecting a first key button of the plurality of key buttons,

display a first alphabet character assigned with the first key button in the text window, and display a first sub key button assigned with a second alphabet character on a first region adjacent to the first key button of the keypad, in response to the first signal, and

receive a second signal selecting the first sub key button, and display the second alphabet character next to the first alphabet character in the text window, and display a second sub key button assigned with a third alphabet character on the first region adjacent to the first key button of the keypad, in response to the second signal,

wherein the second alphabet character is predicted as a next character of the first alphabet character, and

wherein the third alphabet character is predicted as a next character of the first and second alphabet characters.

2. The digital television of claim 1 further comprising a memory, wherein the second and third alphabet characters are extracted from the memory.

3. The digital television of claim 2, wherein the second alphabet character is extracted from the memory based on a first word related to the first alphabet character.

4. The digital television of claim 2, wherein the third alphabet character is extracted from the memory based on a second word related to both the first and second alphabet characters.

5. The digital television of claim 3, wherein the first word is the same as the second word.

6. The digital television of claim 4, wherein the first word is the same as the second word.

7. The digital television of claim 3, wherein the controller is configured to display the first sub key button together with information about the first word on the display unit.

8. The digital television of claim 7, wherein the controller is configured to:

receive a third signal selecting the information about the first word, and

display the rest of the alphabet characters of the first word at the same time such that the rest of the alphabet characters are displayed next to the first and second alphabet characters in the text window.

9. The digital television of claim 1, wherein the controller is configured to concurrently display both the first sub key button assigned with the second alphabet character and a third key button assigned with the same second alphabet character.

10. The digital television of claim 1, wherein the controller is configured to concurrently display both the second sub key button assigned with the third alphabet character and a fourth key button assigned with the same third alphabet character.

11. The digital television of claim 1, wherein the controller is configured to:

display the first and second alphabet characters in the text window as a first style, and

display the rest of the alphabet characters in the text window as a second style different from the first style.

12. A method of controlling a digital television, the method comprising:

displaying, via a display unit, a keypad including a plurality of key buttons which are assigned with different alphabet characters, respectively, and a text window;

receiving, via a controller, a first signal selecting a first key button of the plurality of key buttons;

displaying, via a controller, a first alphabet character assigned with the first key button in the text window, and displaying a first sub key button assigned with a second alphabet character on a first region adjacent to the first key button of the keypad, in response to the first signal;

receiving, via a controller, a second signal selecting the first sub key button; and

displaying, via a controller, the second alphabet character next to the first alphabet character in the text window, and displaying a second sub key button assigned with a third alphabet character on the first region adjacent to the first key button of the keypad, in response to the second signal,

wherein the second alphabet character is predicted as a next character of the first alphabet character, and

wherein the third alphabet character is predicted as a next character of the first and second alphabet characters.

13. The method of claim 12, further comprising a memory, wherein the second and third alphabet characters are extracted from the memory.

14. The method of claim 13, wherein the second alphabet character is extracted from the memory based on a first word related to the first alphabet character, and the third alphabet character is extracted from the memory based on a second word related to both the first and second alphabet characters.

15. The method of claim 14, wherein the first word is the same as the second word.

16. The method of claim 14, further comprising:

displaying the first sub key button together with information about the first word on the display unit.

17. The method of claim 16, further comprising:

receiving a third signal selecting the information about the first word; and

displaying the rest of the alphabet characters of the first word at the same time such that the rest of the alphabet characters are displayed next to the first and second alphabet characters in the text window.

18. The method of claim 12, further comprising:

concurrently displaying both the first sub key button assigned with the second alphabet character and a third key button assigned with the same second alphabet character.

19. The method of claim 12, further comprising:

concurrently displaying both the second sub key button assigned with the third alphabet character and a fourth key button assigned with the same third alphabet character.

20. The method of claim 16, further comprising:

displaying the first and second alphabet characters in the text window as a first style; and

displaying the rest of the alphabet characters in the text window as a second style different from the first style.

21. A display device comprising:
