You answered your own question already.
way2roll sort of confused the issue I initially thought but appears was appropriate response given you verified they are 120V AC TVs yet are still asking what the difference is.
assuming this is your first RV (I hope), you’ll find that some electrical devices run off the batteries (12v DC) and others run off AC (household) current which is achieved by magic (inverter) or shore power/generator.
FWIW this basic knowledge is worth learning or make sure you have bribed a mechanically inclined friend or RV tech to receive your calls at 12am when a battery dies or the power goes out, so you can navigate the basics of RV operation.
