Cell Phone Displays are cheap and have high-resolution and touch sense, but use varied specialized inputs via ribbon cable. So, has the DIY community made any controllers to input HDMI? What about the touch sensor?
Recently, I only know of one solution, which is exactly that. It is open source and a great accomplishment, however, it does not support touch, yet still is not cheap, which defeats the purpose.

The single-board PC market has a selection of cheap, low resolution, touch screens. They input HDMI, and output USB.
This is an update to the old question Is it possible to wire up a cellphone screen to work with a different device?
This question isn't necessarily seeking consumer products as much as home-made devices.

Interfacing to random LCD panels is still in the "Wild West" phase. It may take a lot of hacking and going through solutions that won't work. There are US$20 boards from China that claim to be able to interface to a variety of raw LCD panels. They come with all the "TV receiver" functionality including an off-air TV tuner and HDMI input and even composite and RGB (or component) input. It is pretty much a gamble whether any of them will work for any particular display panel and it's not even a good bet at this point in history (May, 2016). Good luck.
