Before diving into the computer monitor components in details, let’s understand the basics of a computer screen in easy and simple words.
What Is a Computer Screen? Easy Definition in Simple Words
A computer screen is the part of a computer that shows you everything you do. It displays text, pictures, videos, games, and more. You see your work, watch movies, or scroll through websites—all on the screen.
It’s also called a monitor or display, and it’s one of the most important parts of a computer setup.
Role of a Computer Screen in Daily Use
We use computer screens in many parts of our life—at home, school, and work.
- You read documents, write emails, or browse websites.
- You watch videos, play games, and attend online classes.
- You design, draw, or edit photos and videos.
- You control your computer by looking at and clicking things on the screen.
Think of the screen like a TV for your computer — but smarter and more interactive.
Knowing the parts of a computer screen helps you understand how it works and how to choose a good one when you need to upgrade or fix it.
Types of Computer Screens
There are different types of screens based on how and where they are used. Here are the most common ones:
1. Monitor (Desktop Screen)
This is the screen used with desktop computers. It is larger in size and usually connected through cables like HDMI or VGA. Most homes and offices use monitors like LED, LCD, or curved screens for work and entertainment.
2. Laptop Screen
A laptop screen is built into the laptop body. It is smaller than a desktop monitor but does the same job—showing you everything the computer is doing. You can carry it anywhere.
3. Touchscreen
This type of screen lets you touch and control things directly. You don’t need a mouse or keyboard for everything. Touchscreens are mostly used in tablets, smartphones, and some modern laptops.
4. Cathode Ray Tube (CRT)
This is an old type of computer screen used before LCD and LED became popular. CRT (Cathode Ray Tube) monitors were big, heavy, and bulky. But they were the first widely used display technology in earlier computers.
So, the wait is over! It’s time to learn about the parts of a computer monitor in a simple, beginner-friendly way.
Main Parts of a Computer Screen and Their Functions – Explained in Simple Way
Let’s now explore the main computer screen components and what each one does in simple terms. This will help you know your screen better, whether you’re using a desktop monitor, laptop, or even a touchscreen.
1. Display Panel – This is the heart of your screen.
It shows all the content—text, images, videos, and everything you do.
- It is the main visible part of the screen.
- Everything you see—movies, games, documents—appears here.
- Different panel types offer different screen quality.
Types of Display Panels:
- LCD Screen (Liquid Crystal Display): Common and affordable.
- LED Screen (Light Emitting Diode): Brighter and energy-efficient.
- OLED Screen (Organic LED): High contrast and better colors.
Example: Most home and office monitors use LED panels today.
2. Bezel (Outer Frame) – This is the border around your screen.
It keeps the display panel protected and supported.
- It surrounds the screen from all sides.
- Gives strength and shape to the monitor.
- Thick bezels are old-style, thin bezels are modern.
Thin bezels look stylish and give more viewing space.
3. Backlight – This lights up the screen from behind.
Without a backlight, you won’t see anything on the display panel.
- It helps you see text and images clearly.
- Affects screen brightness and color sharpness.
- Most screens use LED backlighting now.
Tip: Good backlighting reduces eye strain and makes viewing more comfortable.
4. Pixel Grid (Resolution) – These are tiny dots that form images.
Pixels are the building blocks of the screen picture.
- More pixels = sharper and clearer images.
- The number of pixels on a screen is called resolution.
- Another important term is dot pitch. It means the distance between two pixels on the screen. A smaller dot pitch gives a sharper and clearer picture because the pixels are closer together.
Common Resolutions:
- HD (720p): Basic clarity
- Full HD (1080p): Sharp and clean visuals
- 4K (Ultra HD): Ultra-clear, detailed viewing
Example: 4K screens are best for video editing, movies, and high-quality games.
Here is a computer screen parts diagram to help you understand it more easily.
5. Ports and Connectors – These are the connection points of your screen.
They allow you to link your screen to other devices.
Common Ports:
- HDMI: High-quality video and audio
- VGA: Older connection type, still used sometimes
- DisplayPort: Great for high-resolution displays
- USB ports: Connect external devices like a mouse or pen drive
Tip: Always use HDMI for better display and sound quality.
6. Stand or Mount – This keeps your screen stable on a surface.
It supports the screen and holds it at a comfortable position.
- Stands can be fixed or adjustable (height, angle, tilt).
- Some monitors can also be wall-mounted.
Example: Adjustable stands are helpful for office work and better posture.
7. Control Buttons / Touch Controls – These help you manage screen settings.
They are small buttons on the side or bottom of the screen.
- Used to change brightness, contrast, volume, etc.
- Found on most monitors and some laptops.
- Some modern screens have touch controls instead of buttons.
Easy to use when you want quick adjustments without using the keyboard.
8. Built-in Speakers (if available) – Some screens also give you sound.
Not all monitors have built-in speakers, but some do.

Bonus Section: Anatomy of a Computer Screen – Inside the Screen
Have you ever wondered what’s inside your computer screen? Let’s take a quick look!
These internal parts help your screen work smoothly—but don’t worry, we’ll keep it super simple.
Display Driver Board – The Brain of the Screen
This is like the control center of your screen.
- It controls what you see on the screen.
- It receives signals from the video card (graphics card).
- It sends those signals to the pixels to create images.
- Without this board, your screen won’t work at all.
Think of it like the “CPU” of the screen—it tells the display what to show.
Power Supply Board – Gives Power to the Screen
This part sends power to all other parts of the screen.
- It takes electricity and distributes it safely.
- Helps other parts work without damage.
- Also manages brightness, power consumption, and power-saving features.
It’s like the battery charger inside the screen.
Internal Cables – The Connectors Inside
These are small cables that connect all parts inside the screen.
- They carry signals and power from one part to another.
- Some cables connect the display to the power board or speaker.
- You usually don’t see them, but they do an important job.
Just like wires in a house, these cables keep everything connected.
Here’s a simple diagram to help you understand the internal parts of a monitor.
