Abstract

A software update method for a display device includes: storing a first software program by a first memory of a computer device; electrically coupling the computer device to the display device; controlling a display card of the computer device by a public application programming interface (API) function of a driver program of the display card or by a physical address of the display card searched by a search program coded by an operating system of the computer device; transferring the first software program stored in the first memory to the display device through a display data channel (DDC) of the controlled display card; and, receiving the first software program by the display device and updating a second software program stored in a second memory of the display device into the first software program by a microcontroller of the display device.

Claims

1. A software update method for a display device, comprising:

storing a first software program by a first memory of a computer device;

electrically coupling the computer device to the display device;

controlling a display card of the computer device by a public application programming interface (API) function of a driver program of the display card or by a physical address of the display card searched by a search program coded by an operating system of the computer device;

transferring the first software program stored in the first memory to the to display device through a display data channel (DDC) of the controlled display card; and

receiving the first software program by the display device and updating a second software program stored in a second memory of the display device into the first software program by a microcontroller of the display device.

2. The software update method of claim 1, further comprising:

reminding that the display device has already updated the second software program into the first software program by the display device.

3. The software update method of claim 2, wherein the display device reminds that the display device has already updated the second software program into the first software program by using an on-screen display (OSD) to display a reminding image on a screen of the display device.

4. The software update method of claim 1, wherein the first memory comprises a flash memory, a hard disk or an electrically erasable programmable read-only memory (EEPROM).

5. The software update method of claim 1, wherein the second memory comprises a flash memory or an electrically erasable programmable read-only memory (EEPROM).
