5. CRT monitor
A CRT (Cathode Ray Tube) monitor is an older type of display device that uses a cathode ray tube to display
images. Here’s a brief overview:
Characteristics:
- Uses an electron gun to shoot beams of electrons onto a phosphorescent screen
- Bulkier and heavier than modern monitors
- Lower resolution and refresh rates compared to modern monitors
- Typically has a 4:3 aspect ratio
How it works:
1. The electron gun shoots beams of electrons onto the phosphorescent screen.
2. The electrons excite the phosphor coating, causing it to emit light.
3. The light is then focused onto the screen, creating the images.
Advantages:

6. Disadvantages
Here are the top 5 disadvantages of a CRT (Cathode Ray Tube) monitor:
1. _Bulky and Heavy_: CRT monitors are large and heavy, making them difficult to move or transport.
2. _Higher Power Consumption_: CRT monitors consume more power than modern monitors, increasing
energy costs and heat generation.
3. _Contains Toxic Materials_: CRT monitors contain toxic materials like lead and mercury, which can be
hazardous to the environment and human health.
4. _Limited Viewing Angles_: CRT monitors have limited viewing angles, making it difficult to view the
screen from the side.
• 5. _Flicker and Eye Strain_: CRT monitors can cause flicker and eye strain due to the scanning electron
beam.

7. LCD monitor
Define
An LCD (Liquid Crystal Display) monitor is a type of display device that uses liquid crystals to
block or allow light to pass through. They are commonly used in computers, laptops, and
other electronic devices.
Here are some key characteristics of LCD monitors:
- Thin and lightweight design
- Lower power consumption compared to CRT monitors
- Higher resolution and refresh rates
- Wider viewing angles
- Environmentally friendly (contains less toxic materials than CRT monitors)

8. LED monitor
• An LED monitor is a type of display device that uses Light Emitting Diodes
(LEDs) to illuminate the liquid crystals in the display panel.

9. OLED monitor
• An OLED (Organic Light-Emitting Diode) monitor is a
type of display device that uses organic compounds to
produce light when an electric current is passed through
them. Each pixel in an OLED monitor is made up of three
sub-pixels, one for each primary color, which can be
turned on and off independently to produce true blacks
and a wide range of colors.

10. IPS monitor
An IPS (In-Plane Switching) monitor is a type of LCD (Liquid Crystal Display) monitor that uses a specific technology to
improve the display’s color accuracy, contrast ratio, and viewing angles.
IPS monitors are known for their:
1. Wide viewing angles: IPS monitors maintain their color accuracy and contrast even when viewed from the side.
2. Good color accuracy: IPS monitors are known for their accurate and vibrant color representation.
3. High contrast ratio: IPS monitors can display deep blacks and bright whites, resulting in a high contrast ratio.
4. Fast response time: IPS monitors typically have a fast response time, which reduces ghosting and blurring.
IPS monitors are commonly used in:
1. Graphic design and photography
2. Gaming
3. Video editing
• 4. Professional applications where color accuracy is critical

11. TN monitor
A TN (Twisted Nematic) monitor is a type of LCD (Liquid Crystal Display) monitor that uses a specific technology to control the liquid crystals in the display
panel.
TN monitors are known for their:
1. Fast response time: TN monitors typically have a fast response time, which reduces ghosting and blurring.
2. Low input lag: TN monitors often have low input lag, making them suitable for gaming and other real-time applications.
3. Affordable price: TN monitors are generally less expensive than IPS or VA monitors.
However, TN monitors also have some limitations:
1. Limited viewing angles: TN monitors can suffer from decreased brightness and color accuracy when viewed from the side.
2. Lower color accuracy: TN monitors may not have the same level of color accuracy as IPS or VA monitors.
3. Lower contrast ratio: TN monitors may not be able to produce the same level of contrast as IPS or VA monitors.
TN monitors are commonly used in:
1. Gaming monitors

12. QLED monitor
A QLED (Quantum Dot Light Emitting Diode) monitor is a type of display technology developed by Samsung. It uses tiny crystals to
create colors, resulting in improved color accuracy, brightness, and contrast.
QLED monitors are known for their:
1. Improved color accuracy: QLED monitors can display a wider range of colors, resulting in more vivid and lifelike images.
2. Higher brightness: QLED monitors can produce higher peak brightness levels, making them suitable for use in well-lit
environments.
3. Better contrast ratio: QLED monitors can display deeper blacks and brighter whites, resulting in a higher contrast ratio.
4. Wide viewing angles: QLED monitors maintain their color accuracy and contrast even when viewed from the side.
QLED monitors are commonly used in:
1. Gaming monitors
2. Professional graphics and video editing
3. High-end entertainment and multimedia applications
• 4. Medical and industrial imaging applications where color accuracy is critical.

13. 4K monitor
A 4K monitor is a type of display device that has a resolution of 3840 x 2160 pixels or higher. This is four times the resolution of a Full HD (1080p)
monitor, hence the name “4K”.
4K monitors are known for their:
