Liquid Crystal Display (LCD) Solution

LCD contains Liquid crystal solution, separated by two sheets of polarized material. Crystals either allow the light or block the light to pass. LCDs are made up of monochrome pixels. These pixels are sub divided in sub pixels which can be controlled to yield many number of possible colors.

LCD displays mostly are used is followings:

1. Watches
2. Cell phones
3. Televisions
4. Digital televisions
5. Computer Monitors
6. Pocket Calculator

These are of less size, No bulky picture, this application is important where size and weight are important

They require very less power.
They have some limitations as well, as problem with view angle and response time in CRTs.

The man who improved the LCD and kicked off the markets is James Fergason who graduated from Missouri University in 1956 with a degree in Physics and then joined research laboratory where he studied Liquid crystals.

James did not discover how to use LCD .The first commercial use of LCD came in quartz watches and James finally created his own manufacturing company.

The man’ latest invention includes safety eyewear whose liquid crystals became opaque instantly when hit by intense radiation like lasers, thus protecting eyes.
