Panels do not matter as much in HDTVs as they do in LCD monitors. Image circuits are much more important in TVs. I believe that's why no HDTV panel databases are available.
Most Samsung and Sony LCD-TVs use S-PVA.
Most Philips high-end TVs use Sharp's ASV panels.
LG uses LG.Display S-IPS panels.
Panasonic and Toshiba mainly use their own IPS variant for their small LCD-TVs.
BUT you will have to dig through the individual threads to get actual panel type and model numbers. I do not think they have all been collected together anyplace.
