Why OLED? mainly because of best contrast by having no backlight annoying leakage.
Why smartphone or tablet screen? because of size, resolution and price.
usage requirements, previous tests, etc
I was looking for a way to use a tiny smartphone screen near my face, about 30cm is the much I need to focus w/o hurting my eyes out of strain.
My initial obvious research was to buy a Full HD (1080p) OLED monitor (because of possible lower price), but there are only 55"+ TVs available with prices that are at least 3x the full price of my whole desktop computer!!! Probably because of reasons explained here: https://www.monitornerds.com/oled-pc-monitors/, mainly the waste of materials from it's making failures.
I have already used a smartphone like that tho, with lag and lower image quality, thru NoMachine as a server on a linux desktop, the lowered quality only happens because of high framerate required from 3D games or videos tho, not from still images like programming code etc, when NoMachine works marvelously.
Also the small smartphone screen size requires it to be too near my face (less than 30cm), so I still need to find proper lens to use with it (for both eyes). In that case a bigger screen tablet (still OLED tho) could be a MUCH less complex and still cheap alternative.
So back to the specific problem
The goal is performance on high framerates and keeping the quality in graphics details.
Is it possible to, after disconnecting or buying an OLED tablet/smartphone screen replacement, interface it with a desktop PC thru some kind of HDMI or VGA controller to the desktop/notebook PC?
The best would be to provide a model to let a specific answer be provided, but I need to know if it is possible at all with any OLED screen or some specific one, as I would even still need to buy a tablet screen replacement 10"+.
In short, have someone done something like that already? if so, what could you specifically suggest that I could try? what model, pieces, parts I should buy/use?
interesting but offtopic
I also wonder if there is something available in the market already capable of doing something like that? Instead of using an arduino or the like.
Btw, if OLED tablets/smartphones had HDMI video !INPUT!, this very question would be no more at all...
There are Notebooks with HDMI-IN : http://www.tomsguide.com/answers/id-3532875/tablet-laptop-hdmi-input.html#20229443
There are cards that can capture HDMI and directly convert it to an USB port http://www.tomshardware.com/answers/id-3562140/input-video-laptop-tablet.html#r20357924 or http://forum.tabletpcreview.com/threads/do-any-tablets-support-av-input.49423/#post-281048 (if this could be plugged on tablet/smartphone as OTG would be great!)
How are OLED screens driven?
Obs.: I am not an expert at all, just the ideas/coder guy, and will have a friend helping on making the hardware part of it, if not it all. Basically I guess it means I could have questioned more technically if I could.
PS.: I dont know if there is a better stackexchange site to ask this kind of question? suggestions are welcome, as such subject is haunting me ;) for some years now... I am still researching, but I will ask this already.
