if you are talking about the strips that you put on your forehead
it isn't an LCD strip
instead there are different thermochromic inks applied to different parts of the strip.
when heat is applied to the inks they change colour
and with the use of different inks, they change colour at different temperatures
because of this, you can see your temperature (:
help much?

LCD strip thermometers have liquid crystal material that changes color based on temperature. Each color represents a specific temperature range. As the temperature changes, the liquid crystals realign and the color seen on the strip changes accordingly, providing a visual indication of the temperature.

What are strip thermometers?
Strip thermometers are thin, flexible adhesive strips that contain temperature-sensitive indicators to measure body temperature. They are typically placed on the forehead or other parts of the body to track changes in temperature. Strip thermometers are easy to use, non-invasive, and provide a quick way to monitor body temperature.
What are the 16 types of thermometers?
The 16 types of thermometers include mercury, digital, dial probe, infrared, medical, food, liquid crystal, bimetallic strip, gas, resistance temperature detector (RTD), thermocouple, pyrometer, oven, candy, alcohol, and compost thermometers.
Different types of thermometers and their uses with pictures?
There are several types of thermometers. Clinical thermometers are used to measure the body temperature of the patient. Ear Thermometers make it an accurate point to measure the body temperature. Pacifier thermometers are used to check the body temperature of babies or infants. Underarm thermometers are kept in the underarms to measure the body temperature. Not to mention the food thermometers that are often used for checking the heat of the oil or pop up to let you know when the meat is done.
What are alternatives to thermometers?
Some alternatives to thermometers include thermal cameras, infrared thermometers, and non-contact forehead thermometers. These devices can measure temperature without physically touching the person.
What liquid used to be in thermometers?
Most thermometers used to contain Mercury until it was found to be toxic.
How do LCD thermometers work?
The LCD thermometers work much the same way as a bimetallic thermometer, only the circuitry inside the electronic thermometer measures the temperature through resistance. Through expansion, the device will have a higher resistance in higher temperatures, and the computer inside will make note of that. The temperature it derives is then displayed on an LCD screen. Then it works. http://www.dinodirect.com/Components/LCD-Monitor
What is an LCD Thermometer?
In market there is availability of two types of Thermometers [1] Glass and [2] Digital. Digital Thermometers are LCD Thermometers. The thermometer measures the body temperature in shows digitally in numbers and alphabets.
What are strip thermometers?
Strip thermometers are thin, flexible adhesive strips that contain temperature-sensitive indicators to measure body temperature. They are typically placed on the forehead or other parts of the body to track changes in temperature. Strip thermometers are easy to use, non-invasive, and provide a quick way to monitor body temperature.
Why liquid in glass thermometers are not suitable for industrial work?
Liquid in glass thermometers are fragile.For precise work, they need to be recalibrated frequently.
How do laser thermometers work?
Laser thermometers are actually just infrared thermometers. The laser is actually just there to make the thermometer easier to aim.
How do bimetallic thermometer work?
Bimetallic thermometers work based on the principle that two different metals expand at different rates when heated. A bimetallic strip is made by bonding two different metals with different thermal expansion coefficients together. When the temperature changes, the strip bends due to the uneven expansion of the two metals, which is then measured to indicate the temperature.
What do forehead thermometers do?
Forehead thermometers are designed to measure body temperature by scanning the forehead. They detect the infrared heat emitted by the body and provide a temperature reading quickly and easily without direct contact. These thermometers are non-invasive and convenient for checking for fever.
What are thermonmeters made of?
Thermometers are made from a graduated glass tube with a liquid inside that expands when heated. The liquid could be mercury but is more likely to be coloured alcohol.Two strips of metal that are joined together. One metal expands on heating faster than the other one so when heat is applied the strip bends. The amount of bending depends on temperature. A dial either physical or electronic can be used to read the temperature. Useful for high temperatures.Simple strip LCD thermometers depend on the property of liquid crystals to change over a narrow temperature range.The use of any property of a material that changes with temperature eg electrical conductivity, radiation, density (have you seen those cool thermometers with the floating bulbs?) can make a thermometer.
What principle do most thermometers work?
Liquid expands as it gets warmer.
How is temperature measured in Antarctica?
Thermometers are very effective in measuring temperatures, in both C and F degrees.
Is bimetallic strip is used in spoon?
A bimetallic strip is not typically used in spoons. However, bimetallic strips can be found in devices such as thermostats, thermometers, and switches due to their ability to bend when exposed to temperature changes, which can be used to control electrical circuits.
What would happen if I placed a magnetic light strip on the back of my LCD TV, would it break the TV?
Probably yes !
