  • the present invention relates to a display apparatus with a scanning unit.
  • the present invention relates to a display apparatus having a display unit and an integrated scanner that is capable of scanning a document placed below the display unit.
  • a user When performing a scanning operation, a user typically uses a scanning device to scan a document. After the document has been scanned, the user might view or edit the scanned document. This is done on a separate display device, such a monitor of a personal computer (PC). In other words, the scanning operation is performed on one device (scanner) whilst the viewing of the scanned document is performed on another device (monitor). This can be cumbersome for the user.
  • the scanner and the PC might be in different rooms, or the scanner and the monitor might be connectable using a cable thereby restricting where the devices can be located in the same room.
  • having two separate devices for the scanning and the displaying takes up unnecessary space.
  • operation of a conventional scanner is typically cumbersome. For example, when scanning a document, the user is required to place the document in alignment with a marker or a ruler on the scanner so that when the scanned document is displayed, the image is correctly aligned.
  • the user typically needs to flatten the document as much as possible before scanning to obtain a good image of that document. For example, if a user has a letter that has been kept in a folded state for a long time which he now wishes to scan, using conventional scanners the user would need to flatten the document as much as he can just before scanning. Or, the user might hold down the creased document with his hand, or place a weight or a flat cover over the document. Otherwise, a perfect flat image of the document cannot be achieved. Also, creases show up in the scanned image. Another example is when there is a thick book to be scanned. Unless the user manages to flatten the book completely, it is difficult to get a perfect flat image of the page in the book.
