If you are always going to have mains electricity the I would go for a mains voltage television. They are about half the price of multi-voltage ones !
Obviously if you are going to be sited without an EHU you will need a 12v unit but, depending on the size of your battery, you won't be watching for long without a re-charge.
It depends how stable the voltage is. If it is stable I would go for AC but if is all over the place, or there are frequent interruptions I would go for 12V DC.

Running on 12v DC, a 19" – 22" LCD TV can draw up to 8 amps per hour.
If you switch it on for the 6 o’clock news and watch it through till midnight that’s approx. 48 amps out of your battery!
At that rate, it’s going to need recharging virtually every day.
I would suggest buying a normal mains voltage TV and a 12v DC to 230v AC "Inverter" for the odd occasion when there is no mains hook-up available.
Better still, A lot of TV’s nowadays are actually 12v DC but come with a transformer to allow it to be run off the mains (230v) supply. (Similar to most powered cool boxes).
To answer your other question, you will not need a voltage regulator in the UK or most other western European countries.
Yep, in the analogy of a water hosepipe, the current is the flow of water running along the pipe and the voltage is the force at the start of the pipe.
It can get more complicated with dc because there is voltage drop if the "pipe" is long or thin

Why not get a Kogan mains powered TV with DC option? These are superb sets and start off at £89 for a 19". Supplied with mains adaptor as standard with the option of a dedicated DC cable for 12v use.
25w at 12v (3.3amp draw).
22" TV for camping!!! Thats a bit over the top, mine in my house is not even that big. Althougth the person across the street has a huge one and if hes watching the same as me I just open the curtains, swivel the chair to the window, turn down the brightness on mine and watch his!
Paul if you stick a meter on the Kogan TV's you will find they actually draw considerably less than the quoted figures which I believe are the maximum load. All good stuff if anyone is worrying about a TV using a lot of power. I'm really impressed with my Kogan 22" TV both in performance and value for money. Now if they did a set that also included a Freesat receiver I could well be tempted again.....

I'm absolutely sure your right, the spec in the manual will be max draw with brightness flat out, contrast wound up, volume shaking the windows etc.
They are a cracking set though and worth checking out, especially given the unreasonably high costs of so-called 'dedicated' caravan TV's.
