📺 How does a TV work?

📺 A TV is like a magic box that shows pictures and sounds! 🎶 It gets signals from far away (like from a TV station or the internet) and turns them into moving pictures and sounds you can see and hear.

Inside the TV, tiny lights called pixels light up in different colors to make the pictures. When they change really fast, it looks like things are moving! 🏃‍♂️

📺 A TV works by receiving signals (like from a broadcast tower, cable, or the internet) and turning them into images and sound. Here’s how:

• Screen Magic: The screen is made of tiny dots called pixels. Each pixel can light up in red, green, or blue. Mixing these colors makes all the other colors you see! 🌈
• Fast Changes: The TV changes these pixels super fast to create moving pictures—like flipping pages in a cartoon book really quickly! 📖
• Sound: Speakers inside the TV play sounds that match the pictures. 🔊

📺 Modern TVs use advanced technology to display images and sound. Here’s a deeper look:

How It Works:

1. Signal Reception: TVs receive data as electrical signals (via antenna, cable, or internet). This data contains instructions for images and sound.
2. Pixel Grid: Screens have millions of pixels (tiny lights). Each pixel has red, green, and blue sub-pixels that adjust brightness to create colors.
3. Refresh Rate: Images update 60+ times per second (Hz) to create smooth motion. Newer TVs use 120Hz or even 240Hz!
4. Display Types:
   • LCD/LED: Use liquid crystals and backlighting.
   • OLED: Pixels emit their own light for deeper blacks.

🔊 Sound comes from built-in speakers or external systems like soundbars.
