DIY portable external tablet size screen for Android phones?

I mostly use a tablet for reading books and watching videos. Those are really the only functions that my tablet is more useful for than my smart phone or laptop. So why not just have a portable high resolution LCD that I can dock my Android phone in to send a signal out via micro HDMI? I find it annoying not being able to access things on my tablet because they're on my phone and vice versa. Sure, there's ways to sync them or store in the cloud but:

1.) Syncing isn't instantaneous...some amount of wait time, particularly when there's no wi-fi available.
2.) Syncing is slow for large files
3.) Why have the same data on 2 devices for 1 person?

I may pull out my phone to read a little bit of a book while waiting in line somewhere when I didn't bring my tablet with me. But when I go home, I'll switch to my 10" tablet just to take make use of the bigger screen. This got me wondering, why not just have a ~10" battery powered high resolution LCD with HDMI input that I dock my phone into? Sure, it won't be as slim as a tablet, but if I'm going to carry around a device that big, I usually have a bag of some sort, so the extra thickness wouldn't kill me. I guess what I'm saying is, in a crunch, I can accomplish the same things (as far as my uses go) on my 720p res phone as I can on my 10" tablet, but it's not viable for extended periods of time and just isn't the same experience as a ~10" screen.

I haven't ben able to find any high resolution portable LCDs with HDMI or DVI or VGA input for less than a tablet. Mostly I just find less than NTSC SD resolution car kit LCDs. Or some of the few portable DVD player that have video input, the resolution is ridiculously low. I suppose someone who's an electrical engineer with some time on their hands might be able to in theory salvage a laptop LCD & driver and some how add HDMI input?

Please note: I could care less about "sexines" of my devices...function over form is the reason I switched to Android from iOS, sick of limitations.
