Make a lovely video setup with a 7" screen at 1024x600 resolution. For this model, we tried to get an inexpensive 1024x600 display that was still high quality and would be good for embedded computing usage. The visible display measures 7" diagonal and is a 'raw TTL' display. We include a driver board with HDMI, VGA and Composite inputs. The setup is very easy to use - simply connect a 5-12VDC adapter to the 2.1mm center-positive DC jack, then connect a digital video source to one of the ports . Voilà, a display!
This version comes in 1024x600 instead of the more expensive 1280x800 display. It's also not IPS so it's not good for wide-angle visibility.
There's a little wired PCB with little buttons that let you enter a menu system for adjusting brightness, color and contrast. It tries to auto-detect which input you have and switches to that one or you can 'select' from the menu which to display.
To demonstrate it, we took some photos with the display connected to a Raspberry Pi, but it will also work connected to any device with HDMI, VGA or NTSC/PAL output. It will not work with a device that only outputs DVI (without a DVI to HDMI converter) or SECAM.
For use with a Raspberry Pi we suggest editing config.txt to set the HDMI to the native 1024x600 in case it doesn't detect the resolution properly. You can see our suggested config.txt in the Technical details tab. The easiest way to edit the config.txt is to put the Pi SD card into an every day computer and edit config.txt with any text editor and save.
For use with a BeagleBone Black running Ubuntu/Debian, we found it works when plugged in, no configuration required.
A power adapter is NOT included. You will need to either purchase a 5-12VDC adapter or you can use one you've already got around the house. We show the display on a bent wire stand which is not included, but you can pick one up here.
Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- HDMI
- HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.
- IPS
- IPS is a type of LCD panel that keeps colours and contrast more consistent when viewed from an angle. This matters for small displays that may be mounted in a dashboard, handheld project, or enclosure where the viewer is not always looking straight on.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- VGA
- VGA has two common meanings in electronics: as a resolution it usually refers to a 640 x 480 pixel image, which is modest detail suitable for basic display or inspection rather than high definition; as a connector it refers to the analogue 15-pin video output long used on computers and monitors. Check which sense a listing means.
