Maybe, sort of. The larger panel mfrs are: Samsung, LG, and Sharp. The smaller panel mfrs are: AU Optronics, ChiMei Innolux, Hitachi, Toshiba, IPS Alpha (Panasonic/Hitachi), S-LCD (Samsung/Sony), and HannStar. The list may be a bit outdated because some mfrs may stop making them or make them in conjunction with someone else.
Finding out who your particular panel mfr is can be very difficult because tv mfrs will change, even in mid-seaon, whose panels they are going to use and for which size. LG, for example, may use AU or ChiMei for some of their smaller panels (40" or less) but use their own panels for some tv's that are 47" or bigger. There are ways to determine what your panel type is but, as I said, it can be challenging.
