Abstract
A display apparatus including an image processor which processes a video signal is provided. The display apparatus includes; a display which displays an image based on a processed video signal; a receiver which receives a key signal input by a user; a storage which stores a password key; and a controller which receives a user's first key signal which comprises an arrow key signal when a password is set up for the display apparatus, sets up and stores the password key which corresponds to the received first key signal, receives a user's second key signal when access is attempted, and allows the access in response to the received second key signal and the stored password key matching each other through a comparison.
Claims18
A display apparatus comprising:
- an image processor configured to process a video signal;
- a display configured to display an image based on the processed video signal;
- a receiver configured to receive a first or second key signal input by a user;
- a storage configured to store a password key;
- and
- a controller configured to receive a user's first key signal which comprises an arrow key signal when a password is being set up for the display apparatus, set up and store the password key which corresponds to the received first key signal, receive a user's second key signal when access is attempted, and allows access in response to the received second key signal and the stored password key matching each other through a comparison, wherein
- the password key comprises at least one digit, and the arrow key signal corresponds to the at least one digit of the password key.
A method of controlling a display apparatus, comprising:
- receiving a user's first key signal comprising an arrow key signal when a password is being set up for the display apparatus;
- setting up and storing the password key which corresponds to the received first key signal;
- receiving a user's second key signal when access is attempted;
- comparing the received second key signal and the stored password key;
- and
- allowing access in response to the received second key signal and the stored password key matching each other, wherein
- the password key comprises at least one digit, and the arrow key signal corresponds to the at least one digit of the password key.
A display apparatus comprising:
- a receiver configured to receive a first or second key signal input by a user;
- and
- a controller configured to receive a user's first key signal which comprises an arrow key signal when a password is being set up for the display apparatus, set up and store the password key which corresponds to the received first key signal, receive a user's second key signal when access is attempted, and allows access in response to the received second key signal and a stored password key which match each other through a comparison, wherein
