lcd display freezing temperature pricelist

Every new motorhome and most new 5th wheel and travel trailers have at least one LCD TV. Many have 2 or more.  The bigger LCD TVs on board RVs and motorhomes have 40-inch screens (or larger).

Today’s technology has come to the point where, for the most part, you will find LCD (or Liquid Crystal Display televisions) being installed almost exclusively in new recreational vehicles.

LCDs are a great choice inside RVs for a number of reasons.  For one, the picture quality is very good.  Plus, they’re not big and bulky like the TVs of yesterday. In fact, some are so thin you can actually mount them on the wall like a picture. LCD flat-screen TVs are even being mounted on motorized bases that retract up flush to the ceiling when not in use.

There is a liquid-based material within the screen of LCD TVs.  Will it be damaged overnight in freezing weather?  Worse yet, if left in storage through the winter in the northern states where temperatures can get bitterly cold, will an LCD flat-screen TV survive?

This means that if your LCD TV is kept in an environment below this range, you must allow it at least 24 hours to acclimate to the proper operating range before you plug it in or turn it on.

When something cold is brought into a warm environment, condensation (or moisture) will be present throughout the device.  Plugging it in or turning it on could result in short circuits, shock, or other catastrophic failure of the unit. If the LCD screen is chilled, even though not frozen, it could fail as well.

Manufacturer limitations on cold storage of their LCD TVs varies all over the map.  Some are rated to handle temps as low as -15F to -20F below zero, while others are barely rated to be stored anywhere near the zero mark.

I was unable to find a single supplier of LCD televisions that would stand behind their product when stored in temperatures lower then the -20F below zero mark.

I live in Minnesota. International Falls, MN is well known as “the ice box of the nation.”  During the very long winter months, temperatures drop to a -40F below quite often. I’ve personally experienced -60F below temperatures, though admittedly only once in my lifetime.

You can remove your LCD televisions from the RV (and I would consider removing VCRs, DVDs, and satellite receivers too), and store them indoors in warmer temperatures.

LCD"s freezing is BS I think. Has anyone actually personally seen it? I think it"s one of those old wives tales that somebody made up and lots of people just blindly believed.

I live in Minnesota and UPS or Fedex or the semi truck drivers that deliver stuff to me do not treat LCDs any different than anything else when delivering them to me during the coldest parts of the winter in MN. The back of their trucks are not heated. I have never had any problem with the computer monitors or LCD TVs I have had delivered in very cold temperatures (well below zero F). And I run a computer store so I get that stuff in all the time during the winter.

I have a GPS in my van that has an LCD screen. Lots of cars do. My van sometimes sits outside overnight when it has gotten down to 20 below or so. Never any problems with the LCD except for very slow response time when it"s really cold.

A refrigerator (colloquially fridge) is a home appliance consisting of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) that transfers heat from its inside to its external environment so that its inside is cooled to a temperature below the room temperature. Refrigeration is an essential food storage technique in developed countries. The lower temperature lowers the reproduction rate of bacteria, so the refrigerator reduces the rate of spoilage. A refrigerator maintains a temperature a few degrees above the freezing point of water. Optimum temperature range for perishable food storage is 3 to 5 °C (37 to 41 °F).[1] A similar device that maintains a temperature below the freezing point of water is called a freezer. The refrigerator replaced the icebox, which had been a common household appliance for almost a century and a half.

A LED-backlit LCD is a liquid-crystal display that uses LED backlighting instead of traditional cold cathode fluorescent backlighting. LED-backlit displays use the same TFT LCD technologies as CCFL-backlit LCDs, but offer a variety of advantages over them

An inverter type air-conditioner adjusts the speed of the compressor to control the refrigerant (gas) flow rate, thereby consuming less current and power. An inverter has precise temperature control and as the set temperature is attained, the unit adjusts its capacity to eliminate any temperature fluctuations.

Lithium-ion batteries, used in smartphones and other connected devices, are liquid and cold temperatures cause the molecules to shrink. This can slow down how the device operates and could lead to LCD screens dimming, loss of button functionality and shorter battery life.

“When temperatures drop below freezing, it’s time to consider how we are using and storing devices,” said Tabatha McKay, area vice president/general manager for UScellular in New England. “It’s important to add additional layers around our phones to protect them against the shock of cold temps.”

* Power up devices. If the forecast includes freezing temperatures, be sure to keep your phones fully charged since battery life drains at a faster rate in cold temps.

* Use body heat. Keeping devices close to your body will be a natural source of warmth. Since the body’s natural temperature is around 98 degrees, placing a phone closer to your body — such as in a pocket — will help regulate its temperature and protect it from extreme cold.

An irreversible temperature indicator that shows if a product, such as vaccine has been exposed to freezing temperatures. It consists of an electronic temperature measuring circuit with associated LCD-display. If the indicator is exposed to a temperature below 0°C ±0.3°C for more then 60min ± 3min the display will change from the "good" status into the "alarm" status. A small blinking dot in the bottom right hand corner of the LCD display indicates that the device is functioning.

The indicator is used to warn of freezing and is packed with DPT and its combinations, TT as well as with Hepatitis B and other freeze sensitive vaccine.

LCD stands for “liquid crystal display,” but this is a bit of a misnomer. In reality, the technology has no liquid components, so it isn’t susceptible to freezing and expansion in extreme cold. (Remember, many vehicles nowadays have LCD displays on their in-dash radios and CD players, and these have not been known to crack in freezing climates.)

An LED (light-emitting diode) TV is nothing more than an LCD TV that uses LED backlighting. Compared to the LCD’s fluorescent-style backlighting, LEDs are more energy-efficient, but they don’t respond to cold temperatures much differently. One exception is that LED lights may actually shine brighter in cooler temperatures, as long as it is not too cold. But what is too cold?

When it comes to durability in cold temperatures, there is no real difference between LCD and LED TVs. An LCD or LED TV may not perform well under extreme temperature conditions. In the cold, the response time of an HDTV picture may lag. For this reason, many LCD and LED television manuals will specify a safe-operating-temperature range. In most HDTVs, this range is about 50–90°F.

The temperature range for safe storage is typically even wider. Most LCD and LED sets are rated for storage in temps as low as -4°F. Always refer to your television’s manual for actual safe-temperature ranges.

If your cabin gets colder than this in the winter, you may want to consider erring on the side of caution. Cover the set in a soft blanket to protect it from dust and direct sunlight, and then store it in a dry place with above-freezing temperatures for the season, or for however long you plan to be away.

If you decide to leave the TV at the cabin for impromptu winter visits, exercise caution when turning it on in a cold room. Allow time for the cabin to warm up before turning on the TV, otherwise the extreme change in temperature may result in condensation inside the set and subsequent damage to the screen.

So, when you arrive at the cottage and fire up the woodstove, fireplace or heater, wait at least an hour (longer is better) for the screen to reach a temperature within the safe operating range. Sounds like a long time to wait, we know. But just think – you’ll have more time for card games and conversation!

Across the Midwest today, hundreds of schools and businesses are closed, dozens of flights and trains have been canceled, and the governors of Wisconsin, Illinois, and Michigan have declared states of emergency as a bone-chilling, breath-taking Polar Vortex bears down on the region. While I slept in Minneapolis, overnight wind chills in the city topped –50 degrees. With temperatures like that, you can’t stay outside for more than five minutes without running the risk of frostbite.

But much of the tech that facilitates our connected modern lives itself loses functionality as temperatures drop below freezing. Batteries, screens, sensors, lightweight materials—the things that power our modern mobile lifestyles—just don’t work when it gets this cold. Here’s what to expect of your gear.

Think about all the gadgets that you regularly plug into a power strip. It’s a lot, right? Besides everyday items like a phone and laptop, you might also have a fitness tracker, smart watch, Bluetooth headphones, digital camera, e-reader, vape pen, drone, or rechargeable bike lights, just to name a few. Most if not all of them are powered by lithium-ion batteries, whose high energy density and ability to handle both low and high currents have made them the industry standard for personal electronics. But those same properties become a problem as soon as temperatures dive below 32 degrees F.

“Lithium-ion batteries suffer so badly in freezing temperatures because they have very little internal resistance,” says Hanumant Singh, an electrical engineer at Northeastern University who builds cold-weather robots for places like Antarctica and Greenland. Less resistance means these batteries generate less waste energy as heat (a good thing in more mild climes). But the absence of waste heat also means they’re more vulnerable when temperatures plummet. The colder it gets, the slower the metabolism of the chemical reaction inside the battery. The battery drains faster as a result. If you’ve ever been texting someone at a healthy-looking 25 percent charge only to have your phone die mid-eggplant emoji two seconds later, you’re familiar with how steep the drop-off can be. “It’s very dramatic,” says Singh. Carrying around a smartphone in any weather colder than –35 degrees F, he says, will kill it completely in 5 minutes—right around the time frostbite would strike the hand holding it.

The performance of individual products will of course vary based on the manufacturer, battery model, and wear and tear on the device. Apple suggests not operating its phones below 32 degrees F. Amazon says the same for the Kindle. Fitbit, on the other hand, recommends a minimum ambient operating temperature no colder than 14 degrees F for its wellness wearables, which should maintain better temperature control based on continuous contact with your skin. But the same general rules apply to anything that uses lithium-ion battery technology.
