Recently, I get an 7inch HDMI touch screen and the features of this screen are:

• 800×480 high resolution
• Capacitive touch control
• Supports Raspberry Pi
• Supports Banana Pi / Banana Pro, comes with Lubuntu, Raspbian images
• Supports BB Black, comes with Angstrom image
• For other mini-PCs, driver is required and should be developed by users
• Not only for mini-PCs, it can work as a computer monitor * just like any other general HDMI screen
• HDMI interface for displaying, USB interface for touch control
• Back light control to lower power consumption

The screen use standard HID protocol, so it is very easy to be integrated into Linux system. So the following I will introduce is about how to use it with DragonBoard 410c which is one kind of 96boards.
