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.

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
LCD freezing point?
I saw a tv documentary in which the host went to the coldest town in Siberia- and he stated that his LCD thermometer couldn't tell him what temperature it was because LCD screens freeze at -20 degrees Celsius
How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
How does an digital thermometre work?
A digital thermometer has a digital controller called a microcontroller inside of it that measure the thermistors teperature by measuring its electric resistance. Then it displays it on a little LCD screen.
What are the types of thermometer?

What is an lcd panel and how is it used?
An LCD panel is actually a LCD screen that is part of your computer monitor or LCD Television. There are different types of screens such as plasma as well, but to answer your question, an LCD panel is the LCD screen on your monitor or television (provided it is an LCD model).
What instrument measures how hot or cold something is?
A thermometer is an instrument that measures cold and heat, together with temperature variations.
Who is the inventor thermometer?
