I'm no expert (not my day job ☺☺ ) above is just what I read. Thanks for reminding me of the TN,VA,IPS thing .
(TBH I believe I confused TN with TFT incorrectly thinking TN panel liquid crystal rotation limitation applied to all LCD panels ☺☺)
Samsung and maybe others make 6 bit +high frc TV panels in 8 bit display mode .
I believe quite a few 4k UHD 2160P panels are also 8 bit panels with +high frc in 10 bit display mode that's what I've read anyway .
the +high frc electronics are part of the panel assy. at least in the newer Samsung TV panels .
I have one in a 2013 Sony R450A in thr BR FWIW it makes full rec709 color according to published Cal man reports
and full 8 bit per Samsung specifications. it's a Samsung 6 bit + high frc SPVA panel in 8 bit display mode with a 10 bit signal interface .
TBH before I got the TV and got the panel no. from serv menu and looked it up I never ran across the + frc thing.
in TV am Still reading about it glad you clarified a couple of things. I will edit my above post in light of this info .
My 2013 Sony R450A Sammy panel makes a real good picture even though it's 6 bit + frc . It doesn't seem to be an issue here grey scale and color gradation are smooth and color banding is minimal when compared to other sets with 8 bit and 10 bit SPVA panels here using AVS HD709 .
I read the newest + high frc TV panels work better than earlier overdrive panels and can do full 8 bit or 10 bit color due to recent advances in electronics and algorithms e.g, 6 bit + high frc in 8 bit mode and 8 bit + high frc in 10 bit mode .
The Sony R4 set actually has better pix than the other 4 including a late 2012 Toshiba w/ SPVA panel and and 2013 LG IPS panel set probably partly due to low black level and decent contrast see below
these panels (at least in Sony's case ) are Samsung LCD cells with Foxconn back light assys.
some comparisons :
2013 Sony R450A Black: 0.022 cd/m2 Contrast: 4750 : 1 Samsung SPVA cell 6 bit + high frc
2014 Sony W600B Black: 0.026 cd/m2 Contrast: 3500 : 1 Samsing SPVA ( *may also be 6 bit overdrive panel )
2014 Sony W800B Black: 0.020 cd/m2 Contrast: 5260 : 1 AUO AMVA5
2014 Sony W850B Black: 0.026 cd/m2 Contrast: 4273 : 1 AUO AMVA5 (*some sizes may be Samsung SPVA-4)
