So Ive been skeptical of these panels, which most of these 2 new sizes are using. Mostly lower cost brands, but also on a 50" Samsung.
The panel is still unidentified, but my guess is it;s a new panel design from Chei Lin.
Anyways, Ive spied many of these at retail outlets. But now I have one in my Bar & Grill, and I must say that it's black levels are pretty impressive.
Ive spied it with the 10x Loupe and the subpixels themselves behave similarly to the S-PVA and MVA panels, darkening down blocks...and this probably contributes to it's good black levels. However the lit colored LED crystals are borken up, and dont transmit as much light through them as do the S-PVA and MVA, which means they are less effecient in transmitting light. This can contribute to lower full white lumenosity levels (however this can be somewhat offset by using a brighter backlight).
The 39" Insigna 39L240A13 is the model. Ive got a 60" Panny Plasma from 2011 up and also a Vizio 37". The Panasonic black levels are clearly superior, however the Vizio (with it's S-IPS panel) is clearly inferior to the Insignia. And the Insignia is closer to the Panasonic than the Vizio in black levels.
The viewing angles are really good too.
Im now recommending these 39" and 50" paneled sets. They are real bargains.
