I was just wondering; I just bought a new smartphone and thought it's got enough power for use as a tablet. I mean, you can plug a mouse and keyboard into it and it has HDMI output... So I could take it to College and do work on it etc. quite easily with a bigger display. I had a look around and there are only about two companies I can find that make them.

Could you take a laptop display and hook it up to a big ass battery then simply output to it? I'm guessing it would need some drivers installed on the phone for that to work or something?

So yeah, as a concept is it possible?

well if your cell phone outputs a signal then all you would need is a simple power supply for your monitor. think of your desktop. I would find a cheap desktop monitor that can take the input your cell is putting out (hdmi hopefully) and then all you would need is to find a way to power your monitor. i beleive monitors are DC powered so I would think you could use a battery pack from power tools.

i would also look into people who are installing these monitors in cars and also maybe check out the http://www.raspberrypi.org . they should have similiar issues

I'm not exactly sure what the OP is asking for here. Are you trying to turn your phone into a laptop that you can use on battery in class or a desktop where the monitor would be plugged in? The latter is possible and all you need is an HDMI adapter cable and an HDMI monitor.

For a battery solution, you would probably be better off just buying a tablet or something like a Chromebook as the cost would be about the same.

That and the Motorola Atrix.

Personally I think this is going to be the future of tablets and laptops. Your phone will house the CPU, GPU, RAM, and storage. Your "tablet" will just be a big display with a battery and digitizer which connects to the phone (probably wirelessly). Your "laptop" will just be your "tablet" + bluetooth mouse and keyboard. Carry as much or as little as you need.

We've already passed the point where extra CPU speed on a laptop is meaningless for 95% of users. Eventually the same is going to happen with tablets, then phones. At that point the larger screen, keyboard, and mouse will just be optional peripherals.
