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?

TaigaLCD 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 element is used in thermometers.?
Mercury (Atomic number 80) is still used in some thermometers.
