Wanted: Higher Resolution Small LCDs

by ethur on Mon Oct 09, 2017 5:03 pm

One product area I'd love to see from Adafruit are higher resolution but small LCD screens. For example, 2 to 3.5 inch displays with at least 800x480 or higher, especially ones that would be compatible with an HDMI driver board.

These would be perfect for two things:
- VR headsets
- DIY viewfinders for video work

these are very hard to find, right now the smallest you can get for 800x480 is 3.5"

You can adapt MIPI DSI smartphone screens to work with some STM microcontrollers or via some FPGA magic - as a HDMI display. Making VR headsets similar to those on the consumer market will be extremely hard and costly - the IP and unique hardware is held closed by given vendor - so at best you could mimic chinese display-glasses.

My own personal quest is to make an external viewfinder for my video camera. I actually started off by buying one of the inexpensive 800x480 projectors from China ($85 CDN), and then ripping it apart for the LCD panel and driver board. Everything works, but it isn't ideal because (a) the screen is a bit bigger than I'd like at 4.3" and (b) the driver board has an overly-large shape that is forcing me to make the enclosure bigger than I'd like. (It has an extra wing simply to extend the ribbon cable connection.)

The new Pimoroni HyperPixel - 3.5" Hi-Res Display is the kind of screen I'd be hoping to find, albeit with an HDMI connection.
