Abstract

A device for upgrading a firmware of a display apparatus is provided. The device comprises a USB port, a USB control chip and a micro-controller. The USB port is adapted for connecting with a storage device providing upgrading data. The USB control chip is coupled to the USB port for controlling the transmission of the upgrading data from the storage device to at least one component of the display apparatus to be upgraded. The micro-controller is coupled to the USB chip and is adapted for reading the upgrading data from the storage device and allocating the upgrading data to the components.

Claims

1. A device for upgrading a firmware of a display apparatus, comprising:

a universal serial bus (USB) port, adapted for connecting with a storage device providing an upgrading data;

a USB control chip, coupled to said USB port, controlling a transmission of said upgrading data from said storage device to at least one component of said display apparatus to be upgraded; and

a micro-controller, coupled to said USB control chip to read said upgrading data from said storage device and allocate said upgrading data to said component of said display apparatus to be upgraded.

2. The device according to claim 1, wherein said component is coupled to said USB control chip and is one of the group consisting of a detector, an optical engine controller, a scalar, and a digital television module, and said detector is adapted to detect a display format of input signals according to a display data channel standard and an extended display identification data recorded by said detector;

said optical engine controller is adapted to control displaying colors of said display apparatus, said scalar is adapted to control the zooming in/out of displayed images under different display formats, and the digital television module is adapted to provide digital television functions of said display apparatus.

3. The device according to claim 2, wherein said display format is one of the group consisting of video graphic array, high definition 1, and high definition 2.

4. The device according to claim 2, further comprising a converter coupled among said scalar, said digital television module, said micro-controller and said USB control chip, wherein said converter transfers said upgrading data from said USB control chip to one of said scalar and said digital television module according to instructions from said micro-controller.

5. The device according to claim 1, further comprising a control bus for transferring commands between said USB control chip and said micro-controller.

6. The device according to claim 1, wherein said USB control chip is a USB slave device and said storage device is a host device.

7. The device according to claim 6, wherein said storage device is a personal computer.

8. The device according to claim 1, wherein said USB control chip supports USB on-the-go (OTG).

9. The device according to claim 8, wherein said USB control chip is a USB host device and said storage device is a slave device.

10. The device according to claim 1, wherein said upgrading data comprises at least one upgrading file and said micro-controller allocates said upgrading file to said corresponding component according to a file name of said upgrading file.

11. The device according to claim 1, wherein said upgrading data comprises at least one of firmware program code and extended display identification data.

12. The device according to claim 1, further comprising a feedback device, for displaying a status and a process of upgrading said firmware.

13. A device for upgrading a firmware of a display apparatus, comprising:

a USB port, adapted for connecting with a storage device providing a upgrading data; and

a USB control chip, coupled to said USB port, the USB control chip controlling a transmission of said upgrading data from said storage device to at least one component of said display apparatus to be upgraded.

14. The device according to claim 13, wherein said component to be upgraded is coupled to said USB control chip and is one of the group consisting of a detector, an optical engine controller, a scalar, and a digital television module, and said detector is adapted to detect a display format of input signals according to a display data channel standard and an extended display identification data recorded by said detector, and said optical engine controller is adapted to control displaying color of said display apparatus, said scalar is adapted to control the zooming in/out of displayed images under different display formats, and said digital television module is adapted to provide digital television functions of said display apparatus.

15. The device according to claim 13, further comprising a micro-controller, coupled to said USB control chip for reading said upgrading data from said storage device and allocating said upgrading data to said component of said display apparatus.

16. The device according to claim 13, wherein said USB control chip supports USB on-the-go (OTG).

17. The device according to claim 13, wherein said upgrading data comprises at least one upgrading file and said USB control chip allocates said upgrading file to said corresponding component according to a file name of said upgrading files.

18. The device according to claim 13, wherein said USB control chip allocates said upgrading file to said corresponding component.

19. The device according to claim 13, wherein said USB control chip is a USB host device and said storage device is a slave device.

20. The device according to claim 13, wherein said USB control chip is a USB slave device and said storage device is a personal computer.
