I er velkomne her incl middag vin/øl og overnatning.
Nu var min reaktion jo ikke målrettet en diskussion om led eller oled, men kun over PeterDs to første sætnInger i hans 10.35 svar. Kantbelyst contra bagbelyst på ledTV.
Men kom bare forbi.
Et LEDTV kan ikke konkurrere med et OLEDs 0 cd/m2. Alligevel kan det se ud som om når værdierne for blackness er følgende:
Picture Quality
Black Level & Contrast Performance
Judging from its subpixel structure, the Samsung UE65JS9000 uses the same PVA LCD panel as the flagship UE65JS9500. Unsurprisingly, native black level was eerily similar once peak white was aligned to our dark-room target of 120 cd/m2, coming in at 0.052 cd/m2 on both full-field video black (with auto-dimming defeated by displaying a pause icon from our OPPO Blu-ray player) and a 4×4 ANSI chequerboard pattern if [Smart LED] was disabled.
Subpixel structure
Engaging [Smart LED] activates the 65JS9000′s pseudo-local dimming system, which not only improved black depth, but also attenuated the initially observed backlight inconsistencies (several patches of clouding near the corners) to negligible levels. Three [Smart LED] settings are available apart from “Off“, namely “Low“, “Standard” and “High“. All three lowered measured black level to 0.002 cd/m2 on a full-black screen with auto-dimming defeated, and 0.043 cd/m2 on 4×4 ANSI.

Ps. PeterD. Er dit Sony bagbelyst?
