1. What is LCD Display?

LCD Displays are also known as Liquid Crystal Displays. LCD is a flat panel display or electronically modulated optical device that uses the light modulating properties of liquid crystals to display information.

Liquid crystals itself don't emit any light though liquid crystals can change colors depending on different voltages. To overcome the issue, engineers and scientists have come up with a solution that can eliminate the back of the crystal display by a backlight with a florescent lamp or reflector.

2. Applications of LCD Display

LCDs were present in the early days on electronic components. In the calculators, watches, digital cameras, aircraft cockpit displays, instrument panels and etc... Due to the compact features of the LCD display and the cost efficiency, they are used in a wide range of applications.
