LED Screens and freezing temperatures.

by rl9god / August 26, 2008 4:56 AM PDT

I am wanting to purchase an LED HDTV, and am wondering what the minimun temperature is that an LED screen will tolerate. The TV is to be placed in a motorhome, that sometimes gets down to 30 below zero.

Thank you

Check the specs

Check the specs for the TV. There's virtually always some kind of information on this sort of thing with all the technical details about power consumption and what not.

My guess however, would be that if you have an LCD -- I'm guessing you meant LCD since AFAIK LED displays, which is a completely different technology, is still a few years off from being practical -- TV in such environments, it would likely be bad for it. The crystals could very well freeze, then expand, cracking the display and generally making a mess.

I would not make such a TV a permanent fixture in an RV.

I guess the same Jimmy. And yes, I meant LCD, Thank you. I haven't ever seen any info. re: temperature in the tech specs. I'll keep looking.

It's usually

It's usually in the back of a manual... One of the last couple of pages that will have things like the maximum power load the unit is rated for, and operating environment information like min and max temperatures, altitude limitations, and even humidity levels.

In general though, I'd say -30F (or even -30C) would probably be far too cold. I would hate to have it below the freezing point of water personally. If it will frequently be getting even that cold inside the RV itself, I would rethink the whole idea.

Thank you Jimmy. It helps to get this idea out of my head and into discussion.

It is still an LCD TV, but with LEDs providing the light and yes they are better. They use less power and are potentially more long lived. Contrary to popular belief, LCD (Liquid Crystal Display) Technology does not involve any sort of liquid whatsoever. LCD panels use tiny microchips that "twist" open to allow light to pass through the display to your eyes. There is no risk of these Crystal "twisters" to freeze. They can get cold, and their "twisting" can be reduced however, but that's about it. I do suggest allow the tv to warm up before use. The answer to your questions would be like asking if it is ok to leave a calculator in a cabin for the winter. Calculators use the same "LCD" technology, and of course, I'm sure the one you left at the cabin last year still works just fine. On a side note, keep in mind, lcd technology has been around for over 50 years (invented by sharp) and the technology is used everywhere, like your car dashboard like GPS and display screens, boeing 747 airplane control panels, laptops. All these items can and will be exposed to freezing temperatures at some time in their lives, and they are still "Living"
