everyone should realize that LG makes most of the higher quality display panels out there. Samsung/Panasonic/Sony/etc. all use LG panels for their TV's. I can't really think of another display maker that matches the same logistical prowess as LG.
No they don't. I happen to be very much into monitor/TV tech.
Samsung uses Samsung/AUO/CMO VA panels in their TVs.
Sony uses Samsung and AUO panels (possibly Sharp soon)
Panasonic uses its own Alpha IPS pro Displays.
These Use LG panels:
Some LGs some Vizios and some Toshibas, which all tend to be second tier TVs.
