Help: Creating an LCD screen 'multiplex' using Android screens Answered

I want to make a large digital image using multiple small screens. I was considering using Android LCD screen replacements and somehow linking them all up into a 2x4 grid (more or less) and was wondering if this were at all possible, and if so,how would one go about constructing it with minimal space between the screens. I have little electrical engineering knowledge so could use all the help i can get! I want to note that the idea would be NOT to have this connected to a computer, but to a MUCH smaller unit that would store content for the screens. Thanks guys

couldnt you just pull apart a lcd monitor and use the screen inside?

Its POSSIBLE of course, but not one for someone with "little electrical engineering", its a vast project, to put all your data in a large frame buffer, and then read out sections of it for the different screens.

People like Matrox and Nvidia DO make controllers for multiple screens, but the screens used are already intelligent. Android replacements AREN'T, and will rely on "smarts" on their motherboards. So you have to supply THAT hardware, for each panel, as well as the distribution stuff.

i'd seek out help from someone more experienced than me in constructing the unit so i am not to worried about that aspect of the project. However, i needed to know where to start. Thanks for the heads up in terms of intelligent screens - where would i find small intelligent LCDs? Is there a specific name for them? And how much battery power (approx.) would it take to power? I know that last question is dependent on several variables, but i am more concerned about physical size of the battery pack.

Why use lots of small ones, when you could use fewer big ones ? Especially since bigger ones are more likely to integrate the bits you need ?

Because I want to integrate it into a garment and would require a bit of flexibility. Originally I had considered LEDs but the diodes are so far apart, wasn't sure if you could get a decent image from an approx 7x10" panel

Power requreiments would be a killer for conventional LEDs, but Oleds might work - though then you are right back at the original problem of display smarts and where they are.

The off the shelf tech is designed to drive standard VGA or HDMI displays, and that's your big problem I'm afraid. I can't see a way to do this that is affordable for a one off.
