1. Liquid Crystal Display (LCD):
- Disadvantages:
1) Limited viewing angles: LCD monitors tend to have restricted angles from which the display is clearly visible. Viewing the screen from extreme angles may result in distorted colors and reduced image quality.
2) Motion blur: LCD monitors can experience motion blur, especially when displaying fast-moving images or videos. It may lead to a blurry or smudged appearance, which can be distracting for users.
2. Plasma Display:
- Disadvantages:
1) Shorter lifespan: Plasma display panels have a limited lifespan compared to other types of monitors. The phosphors used in plasma screens can degrade over time, resulting in reduced brightness and image quality.
2) Higher power consumption: Plasma displays consume more power than LCD or LED monitors. This high power consumption not only increases electricity bills but also contributes to higher heat dissipation, requiring additional cooling mechanisms.
3. Cathode Ray Tube (CRT):
- Disadvantages:
1) Bulky and heavy: CRT monitors are larger and heavier compared to LCD or plasma displays. Their bulky design takes up more desk space, limiting the working area. Moreover, the weight makes it difficult to move or reposition the monitor.
2) Flickering and eye strain: CRT monitors operate by shooting an electron beam at phosphor dots on the screen, resulting in flickering at a low frequency. Prolonged exposure to this flickering can cause eye strain or headaches in some individuals.
