I have just upgraded my Picade to a 12" screen and I am thoroughly pleased. I came across this thread just after posting in another 12" screen thread, but the bottom line is that I was able to obtain an Eyoyo 12" 1024x768 panel from Amazon, though a bit on the pricey side. Listing said it was IPS, and I am quite sure it’s CCFL backlit. Using the ‘steepest’ Picade mount holes, brightness and horizontal viewing angles look great, though vertical not so much.
I’ve uploaded images to Imgur each with a description. The panel itself is labeled “LT121XJ01” but I couldn’t find anything referencing that model online. Hope this info can help in some way!
