smaller sized panels, like 25". The QC/QA can be kept to very high standards. Not so much with large panels, and then consumer panels which are lower price point anyways and lower quality.
But - whole point of me chiming in here was - with Lightspace being modular, and being able to create various LUTs from the same display profile u can try out various approaches.
The 3D LUT cal process for OLED does not differ from standard 3D LUT cals. Just at the very end when u create the cLUT, u'd adjust the color target.
run display profile, then create 3 cLUTs:
(1) use standard color target, e.g. BT1886
(2) use a professionally derived Judd modified WP for the panel in use... if not available, try the one I posted (which was derived on Sony panels) in a custom color space target
(3) use a perceptually derived white point in a custom color space target
in all 3 cases, compare the resulting image on the OLED directly to a standard calibrated display such as LCD or even better Plasma. Plasma has much lower black level and will match the OLEDs very, very closely.... if... the custom white point is good.
simply put on a random movie, stream to both displays simultaneously... look at the moving images and then pause freeze frame and compare. u'll see it.
if u would have a known good, and professionally derived Judd modified white point like #2
, then that would be the very best option.
In a HT environment, where u sit at the end of the chain, if #1
do not provide good results or not available, u have no other option than #3.
I was asked about this before... I could put up an interface and database on DCT for u LG OLED users and u guys can cross compare ur perceptually derived white points and help each other out or we calculate an average across the sample size... but like I posted before, be aware of the data coming from non-lab environment setups (and all the other factors I posted)
but with LG (or any other consumer OLED), u probably have no other choice if #1
is not available.
