LCD display modules are a part of just about everyone's daily lives. While most people encounter LCD display modules in their cellphones or similar personal communication devices, they are also an integral part of commercial technology, ranging from simple voltage meters that are used to test home and office electrical circuits to the most complex medical monitors that are found in neonatal intensive care units.
The rise of LCD display modules in so many different applications came about thanks to advances that enable economical mass production of these easy-to-read and highly efficient displays. The first
LCD display modules were quite expensive. Their uses were limited as they were rather small and relied on rudimentary backup lighting for proper viewing. Those who remember LCD watches of old may recall the cumbersome and battery-draining backlight button that was necessary to illuminate the LCD display at night. Today, LCD display modules rely on more advanced means of lighting. In addition, the LCD displays of today are available in sizes as tiny as those needed for an ultra-miniature precision gauge, as well as in sizes that are sufficient to take center stage in a huge display at a futuristic rock concert.
Most importantly, because LCD displays use liquid crystal technology that does not consume much electricity or rely on moving parts of any type, these display modules can even be operated with solar power in situations where regular power is not available. While most users only encounter such LCD displays on their solar-powered desk or pocket calculators, displays that are powered by the sun or even ambient light are used in various industrial situations as well as in tough field conditions where regular electric power is not available.
Today, LCD display modules are practically ubiquitous, and their advantages are clear for all to see.
