(Liquid Crystal Display) The most common application of liquid crystal technology is in liquid crystal displays. A liquid crystal display consists of an array of tiny segments (called pixels) that can be manipulated to present information. This basic idea is common to all displays, ranging from simple calculators to a full color LCD television. An LCD consists primarily of two glass plates with some liquid crystal material between them. There is no bulky picture tube. This makes LCDs practical for applications where size (as well as weight) are important. Liquid crystal displays are designed for temperature ranges between 0 - 50°C (32 - 122°F).
