Update: we learned that RiTDisplay have started to mass produce those AMOLEDs and have already found some smartphone clients.

IGNIS Innovation, unveiled a new 3.47" 320x480 AMOLED made on an amorphous silicon backplane (a-Si). The new display uses INGIS' new AdMo compensation technology and is made by RiTdisplay.

Today all AMOLEDs are made on LTPS backplanes. Ignis' solution uses a-Si which is cheaper but has stability issues. Ignis says that their new AdMo technology eliminates those issues - and makes the a-Si made AMOLED equivalent in performance to LTPS AMOLEDs. Ignis says that "This opens the door for RiTdisplay and other manufacturers to make state-of-the-art AMOLED displays using existing amorphous silicon equipment" - but they haven't announced when and if RiTDisplay (or other companies) plan to start using the technology.
