Cold Weather and LCD/LED televisions

To add to the confusion:
Three types of LED may be used:

Edge-lit LEDs - in which the LEDs are formed around the rim of the screen, using a special diffusion panel to spread the light evenly behind the screen (the most common use)

LED backlighting (Full array)- behind the screen, whose brightness is not controlled individually

Dynamic “local dimming” backlight - LEDs controlled individually (or in clusters) to control the level of light/color intensity in a given part of the screen.

Could you please quote the "TON" of mis information? whose to know what it is

I believe you. Just had a discussion about this on another forum.

The reason the picture on an LED/LCD TV is sharper is because all those tiny little LEDs turn on and off behind the display instead of the display being constantly lit by really thin tubes.

Same with a laptop computer. Sometimes the tubes or the inverter controlling them fails and the screen goes blank, or so you think. Shine a flashlight at the screen and look closely and you still see the images in the display. Relatively easy fix as it is usually the inverter that is the culprit.

LED TVs are liquid crystal (LCD). The LEDs are the back light which replaces the older fluorescent back light. There are a couple of exceptions which use OLED (Organic Light Emitting Diode). These have millions of individual LED elements that create the picture.

LED=Light Emitting Diodes. They are the same but much smaller on tvs as LED lights on outside the vehicles. So an LED TV can stay out. The LCD is Liquid Crystal Display and it could be a problem. That I would bring in and store in the basement. MY LED tvs were out in the TT all last winter with no issues. The only issue I had was wifey not paying attention and broke it last weekend putting the slide in. So now I get to buy a bigger one:)

In case anyone didn't get it, there is NO "liquid" in a "Liquid Crystal Display" to freeze.

The manual for my LCD say's not to store below -20C so I bring it in for the winter. The LCD display on my camera froze when I left it in my truck for 2 day's at -35C.

Our RV is subjected to temps in the -30's or more for the last 5 winters here in Manitoba and we've had no problems with the 2 LED LCD TVs.
Also, I worked for a major electronics manufacture in Winnipeg for 30 years with
product arriving by transport trucks in these temps in the winter and product was not affected. As mentioned, they should not be powered up till fully warmed up and also any possible condensation inside the unit has had time to dry out.

If you think about the billions of LCD and LED displays that are in cars, motorhomes, boats, and everything else imaginable, is there still a question ?
