2 types of screens used??? topic

Friends I have moto g 2nd gen bought from flipkart in India in October. I also bought 3 of them for my friends in January. When i compare their screens with mine, i found that their screens are a bit yellowish while mine is pure white. Also they are having grid lines seen on screen in sun while mine is not. I think Motorola is using good quality in older ones? Anybody felt same issue?

[Q] Is there a good source for HD plus screens? topic

My kids broke my Nook HD+ screen. I've found some places that advertise screens for -50 but the only ones I've found in stock are 0 or higher. I can get a used nook for that much.:(

Is there a place to get a screen cheap enough to make it worth while to repair it?

[Q] So I have 2 perfectly good screens topic

So the other morning I wake to find my touchpad sitting on its charging cable from where it fell off the table, bent the USB cable and my poor touchpad won't charge. Even better than that I had a spare touchpad that had the flash write lock issue for parts and had just swapped the USB charger board out because it was no longer charging. So I now have 2 perfectly good screens and nothing to do with them.

In was wondering if anyone had resources on the screen/touch. Circuit diagrams or howtos would be great but any input would be appreciated.
