USBD480-LQ043 is a new USB display offering a 4.3" 480x272 pixel TFT LCD with USB interface.

Some additional information is available here:
http://www.lcdinfo.com/products/usbd480-lq043.html

A list of features copied from the above page:
  • 4.3" 480x272 pixel resolution color TFT LCD
  • Hi-Speed USB interface 480 Mbps
  • Optional touchscreen
  • 16 bit colors
  • 8 MB framebuffer memory
  • Display can be updated at 50 frames per second over USB
  • USB powered


Image

There is also touchscreen support built in on the controller board so optionally a touch panel can be added to allow using it also as a control device.

I noticed that Michael has posted new pictures of the device in action. Go have a look here:

Final pricing haven't been determined yet. This will happen when the actual costs become more clear.
There is a limited number of pre-release units available at this time. If interested in one of those it's best to email me and preferably also quickly mention how you would be planning to use it. The reason I'm asking about the planned use is to make life easier for both sides and figure out in advance if the device would be a good match to the needs in it's current state.

There have been couple questions if this display can be used as a secondary monitor in Windows. For the best performance the display is meant to be used directly using the programming API but there exists a test driver that makes the display appear as a secondary monitor that can be used as a desktop extension in Windows.

Currently USBD480 has been tested with Windows and Linux on x86 hardware. OS X should work too but haven't been tested.

There will be also enough information available to get it running on embedded platforms if needed. Some wireless router with USB port and running Linux might be an interesting test platform.

EDIT:
Linux on ARM hardware has also been tested with the USBD480 now.

Hi, I would be interested in getting one if it was possible to change that USB input to either composite or component. Could that be done easily? Thanks.

Coolio! Very useful for planning ;)

Been a bit occupied on building my FreeTrack 6 dof headtracker, but now I'm looking into this again. Also one of the sims I'm into now made their telemetry API available so more and more software is no supporting it as well. Which means more possibilities for me :)

Adding analog input to the current design would take some work. But if there is demand for interface boards with analog input then a version with analog inputs could be considered also.

Yes they can be helpful. One thing to keep in mind is that the drawings don't yet include any of the components on the PCB. Tallest component is the mini USB connector which is less than 5 mm tall. Of course some room needs to be left for the actual USB cable too. But in general if 5 mm room is left for components on top the PCB there shouldn't be problems.

Just a quick picture showing the test setup used with a 640x480 resolution TFT panel prototype:

The TFT panel used is a NEC NL6448BC20-08E that just happened to be available for testing at the time and it is connected to the USBD480-LQ043 controller board with a simple adapter to match the connections.

Also looks like there is no picture posted with a touch panel installed yet so here is the 4.3" display with touch panel:
