a) LED
b) LCD
c) CRT
d) Flat Panel Monitors
- CRT monitors: These were the traditional type of monitors used with desktop computers for many years. They have a bulky, box-like design similar to older televisions. Inside, they use a cathode ray tube that fires electrons at a fluorescent screen to create the image.
- LED and LCD monitors: These are the more modern and dominant types of monitors today. They are flat-panel displays that use light-emitting diodes (LED) or liquid crystals (LCD) to generate the image. They are typically much thinner and lighter than CRT monitors.
- Flat Panel Monitors: This is a more general term that encompasses both LED and LCD monitors. While they are flat and sleek unlike CRTs, they still share the core functionality of displaying information for computers.
The Evolution of Monitors
CRT monitors were the standard for many years due to their affordability and decent picture quality. However, they had several drawbacks:
- Bulkier and heavier design
- Higher energy consumption
- Prone to flickering and eye strain
- Lower refresh rates
With advancements in technology, LED and LCD monitors emerged, offering significant advantages:
- Thinner and lighter design
- More energy efficient
- Sharper image quality
- Higher refresh rates
- Reduced eye strain
As a result, CRT monitors have become largely obsolete, and LED/LCD monitors are the preferred choice for modern computer systems.
So, while all the options (CRT, LED, LCD) are technically monitors, CRT monitors are the only ones that have the traditional bulky design resembling a television and were primarily used with non-portable desktops.
