Liquid Crystal Display Monitor

A type of monitor that produces image by moving liquid crystals that block or allow light to pass through them.

Features

• Light is provided to the monitor via a backlight on the flat panel display.
• A polarizing glass filter is placed both in front of and behind the pixels which are turned on and off electronically.
• There are three different types of LCD displays

Twisted Nematic (TN) [Raw Lesson Content]

TN technologies were used in early LCD. They use low operating voltages making their use with batteries possible. They are still used for monochrome alphanumeric displays. It uses liquid crystals that twist.

Vertical Alignment (VA) [Raw Lesson Content]

VA was used in the early adoption of color LCD. It produces a truer and has the best contrast-ratio performance. A downside is distortion when transitioning colors and it's narrow viewing tilt. It uses liquid crystals that tilt.

In-Plane Switching (IPS) [Raw Lesson Content]

IPS has a high response rate. This is the technology used in LCD televisions and displays. It is the best choice for use on touchscreen displays. It uses liquid crystals that rotate. It also supports a wider range of viewing angles.
