The document compares four display technologies: CRT uses an electron gun and fluorescent screen but has a large, deep, and fragile glass envelope. Plasma displays use ionized gas in cells and are commonly used in large TVs. LCD screens are thinner than plasma but use more power. LED displays provide better contrast, viewing angles, and color accuracy than LCD, but have higher costs and shorter lifespans.

2. What is CRT ? The cathode ray tube (CRT) is a vacuum tube containing an electron gun (a source of electrons) and a fluorescent screen.

3. The CRT uses an evacuated glass envelope which is large, deep, heavy, and relatively fragile. Screen

5. In physics and chemistry , plasma is a state of matter similar to gas in which a certain portion of the particles are ionized. A plasma display panel (PDP) is a type of flat panel display common to large TV displays 30 inches (76 cm) or larger. They are called "plasma" displays because the technology utilizes small cells containing electrically charged ionized gases . What is Plasma?

10. When it comes to power consumption, LCD are still best. The LCD TVs use about half the power than LED.

11. LED HD TVs are a new breed but very expensive. In future LED TVs will be as thin as a credit card.

12. The viewing angle is the angle at which the screen can be watched without any loss of color or contrast. LED provide better contrast and wider viewing angles. Viewing Angle

14. LEDs cost up to 20 percent more than similarly sized LCDs,. However, LCDs offer energy savings and a longer screen lifespan. Cost
