Advice on Small LCD video screens

[prwiley]

I want to incorporate some small LCD screens playing video into an artwork I am planning. I am familiar with basic electronics, microprocessors, etc.,  but I am suffering from a case of I don't know what I don't know in this video area.

I wonder if someone could give advice on two issues (and any related ones I might not know about).

1) Finding bare LED screens 4"-7" or so that can accommodate a 16:9 aspect ratio.

Where does one source these? I have done some searching, but I not finding what I want -- a screen I can incorporate into my own enclosure. I don't need touchscreen capability, just a screen to play video on.

2) What's needed to connect to Raspberry Pi.

A Raspberry Pi 3 looks to me like the most cost-effcient way to playback video (if there's a better way, I'd love to hear about it). It has HDMI out. What's would be needed to get a bare LED screen of the kind noted above ready to hook up to a Raspberry Pi 3? Do I just need some kind of HDMI breakout, or is there some kind of circuitry needed between the LED screen and the HDMI output.

Any help and suggestions gratefully received.

Some options...

4-7" sounds like smartphone territory. Grab the cheapest Android phone/tablet you can find that gives you adequate screen size and quality and you are done.

It's going to take a lot of effort and expense to get a Raspberry Pi and a screen in such a nice complete package.
