US 2009/0222807 A1 · Updating Firmware in a Display Device Using a Serial Bus

Abstract

Updating firmware of a display device. The display device may include a display screen and a video interface for receiving video signals from a host system and providing the video signals for display on the display screen. The display device may include a memory that stores program instructions for controlling operation of the display device. The display device may include a serial bus interface (e.g., a USB interface), which may receive signals from a host computer for updating the program instructions in the memory. A serial bus to first protocol bridge may receive the serial bus signals from the serial bus interface and convert the serial bus signals to signals of the first protocol. A display controller may update the program instructions in the memory of the display in response to the signals of the first protocol.
