Liquid crystal displays offer several advantages over traditional cathode-ray tube displays that make them ideal for several applications. Some additional advantages are that they are flat, and use only a fraction of the power of other older style displays. They also are easier to read and more pleasant to work with for long periods of time. There are some disadvantages though, such as a limited view angle, brightness, contrast, and the most important cost. These limitations are slowly becoming a thing of the past. There are two styles, passive and active. The less expensive passive matrix displays has a poorer picture, view angle, and it is reflected in manufacturing cost. Active matrix displays have great picture and viewing angles, but need more power to run and are much more expensive. Liquid crystal displays show great potential for future growth and improvement. At this time I will go in to about what is a LCD, how they work, how long they last, what their role is in aviation, and its history...
