Its other advantages are its low cost, and good contrast. Low power consumption requirement has made it compatible with MOS integrated logic circuit. It is typically of the order of microwatts for the display in comparison to the some order of milliwatts for LEDs. The liquid-crystal display has the distinct advantage of having a low power consumption than the LED. This is the reason why they are also used to make thermometers. A little amount of heat can easily turn the liquid crystal into a liquid. It must also be noted that liquid crystals are more heat sensitive than usual liquids. Further studies have showed that liquid crystal materials show more of a liquid state than that of a solid. Solids usually maintain their state unlike liquids who change their orientation and move everywhere in the particular liquid. They have both the properties of solids and liquids and maintain their respective states with respect to another. It is actually a combination of two states of matter – the solid and the liquid. We get the definition of LCD from the name “Liquid Crystal” itself. If you want to know in detail about the invention history of LCD go through the article:- Invention History of Liquid Crystal Display (LCD) However the commercially available liquid crystals were not developed until the late 1960’s. The material “liquid crystal” was discovered accidentally by the botanist Freidrich Reinitzer as early as 1888. Note:- If you are looking for a note on technical specifications of LCD Displays for Interfacing it with micro controllers:- here we have a great article on the same:- A Note on Character LCD Display. The article below is developed as two sections:-ġ.
