JapanDisplay is the cheapest vendor and they don't make OLED, they have to get BOE or LG, which only make in large quantities like above 10 millions. Themselves only supply big panels for business classes.I did a look in the specs.
The screen is a dispointment for me imo but I understand Sony gone cheap.
1080p 60fps LCD screen is nothing to talk about.
I expected an OLED screen.
Going against mobile market they matained the 3.5mm audio jack that is a good thing.
