Samsung and Polaroid are a couple of other brands that make 12VDC LCD TVs. I have a Polaroid HD LCD TV model FLM-1511. It draws 4 amps at 12VDC.
I have used it very successfully in my Airstream running directly off the solar charged batteries.
I think this is more efficient than putting your 12 volt battery electricity through an inverter to make 110v then back through the wall wart transformer that came with the TV to get 12VDC again.
I don't believe electricity from the Airstream batteries is a concern regarding the question of harmful voltage spikes or surges. Eventually, the voltage could drop so low that there could be a problem, but it is bad practice to run the batteries too low anyway.

simply stated... use 12 volts if you can. Inverters waste a lot of power in the conversion to DC - as much as 60%, in the form of heat.
I would recommend having a 12V DVD player with a separate 12V LCD display and a separate 12V Audion system. As things get better with DVD quality, replacing the components is cheaper. A 16x9 display is good for wide screen and a 5.1 surround sound for a computer system also is cool. I accomplish the whole deal with a laptop and LCD display. Most laptops have a 12V converter as an option. It is really just a circuit that protects the laptop from dirty power.
oops... left my pocket protector at home 8-)

Wow, thanks for all the replies folks! It makes sense that there must be a brick converter behind the refer cabinet that's plugged into the 120v circuit. I think I'll leave things as they are. Better to enjoy nature and read a book anyway than spend our time watching the tube.
Ok. This is a topic that has eaten a lot of my time in web searching, and I still haven't found what I am looking for.
2Airishuman's link to camping world goes to a 22 inch unit that is sold out. A search on camping world's web site for 12 volt display dead-ends just like other searches on this topic.
I know my batteries vary in output, somewhere between 11.5 to 12.8 volts, depending on the amount of charge. If I understand earlier posts in this thread, this variation may be a problem for a display that requires 12 volts, and thus, the need to regenerate a true 12 volts (which in turn, uses up to 60% more energy by use of an inverter).
If I use a separate HD DVD player (made to work in automobiles), does anyone know of a make/model of a HD LCD display (15 -20 inches) that will work directly from a 12 volt battery system? I will give karma and a big thanks to the soul that cuts the chase by posting make and model.
By the way Airstream25 – Karma to you (make/model listed)!

See my item #9 under "Flat Screen Lcd Tv - 12v Or Inverter?)

The conformal coated circuit boards protect against corrosion and enable the LCD TV to withstand humidity and temperature fluctuations RVers are commonly faced with. Built specifically for over-the-road-use, the JE1907DC 19" Flat Panel LCD Television is mobile video entertainment at its best!
If someone is interested in the Jensen 19" 12V TV, it may be available from West Marine (West Marine). At least it still shows up on the website.
Before changing to a larger 110V TV (with integrated DVD player), we had a 15" Samsung computer monitor with a built-in TV tuner and a separate 12V DVD player. The Samsung used a "brick" power supply which put out 12V. I checked with Samsung and they okayed connecting directly to the trailer's 12V system (bypassing the brick). Despite that, we found we almost never used the TV on 12V, so we accepted the 110V restriction when upgrading. Not having a separate DVD player has also reduced the number of connecting wires!
