Any chance the Win 2 could have an OLED screen? H-IPS is nice, but OLED is definitely the absolute pinnacle of (current) screens, and I think it even uses slightly less power...Probably too expensive, I doubt it.
Also it would ruin the sharpness due to the pentile pixel matrix.
OLED doesn't *need* to be pentile. The problem is many.
1.) GPD is going to want to buy a phone type of display but orient it landscape (horizontal) because phone displays are cheaper.
2.) Most OLED displays in phones are super expensive even in bulk and aren't large. The "cheapest" OLED is 5.5". The ones used in OnePlus, Moto Z2 play, OPPO, etc.
3.) GPD win needs a 720p ish screen. Going higher in resolution is actually much worse which all of these 5.5" screens are.
There is one OLD panel that would fit the bill but it's too large
The Samsung Galaxy Tab 7.7.
7.7" 1280x800 FULL RGB Stripe OLED.
But that screen was in a device that is 5 years old now. So I doubt it would be easy to get in bulk. PLUS it's 7.7" Just way too big.
OLED def isn't going to happen.
