What kinds of display are in use daily in an Office?

Conventional computer systems have used cathode ray tube (CRT) technology for the computer display. However, in the past decade technological advances in thin film transistor (TFT) liquid crystal displays (LCDs) have made this an increasingly popular technology. From an ergonomics perspective, LCD is better for the computer user. Modern LCDs can offer several advantages over CRTs in terms of visual work performance, space and energy savings. Also, LCDs eliminate geometric image distortions and flicker, reduce specular glare problems and Computer Vision Syndrome. LCDs increase screen viewing areas and have better screen privacy than CRTs.
