# Have Cell Phone Display Panel(s) been hacked to accept HDMI?

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. https://hackaday.io/project/364-mipi-dsi-display-shieldhdmi-adapter

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.

• In what sense is the linked solution "not cheap" considering what it has to do? – Brian Drummond May 4 '16 at 20:23
• You may be right. Compared to what I've seen in the market, displays are cheap, even ones that come with controllers. I can get an e980 touchscreen and all for ~$13 shipped. So a$99 board that only converts the video signal makes it useless to me. That's what I meant. Apparently, you're saying the overhead to do so, MIPI DSI->HDMI, is necessarily expensive. I'm just assuming it's not that bad, and the price had to do with not being manufactured in bulk. – HTDE May 4 '16 at 20:52
• I'm afraid the only consistency you'll get is the other question being closed. Your post underscores why we don't allow product recommendations - they go out-of-date relatively quickly. – W5VO May 4 '16 at 20:52
• I think the problem here is that the actual question in the body of your post was not the same question that's in the title, and Dmitry and Nick were reacting to the question in the title, which was off-topic. – Dave Tweed May 4 '16 at 20:52
• You guys are right. Thank you for taking the time to address it. It's just I don't know where else to go. And SE frequently gets a lot of my searches with good info. that's off-topic. – HTDE May 4 '16 at 20:55
