TVs have changed a lot over the years. In the past TVs were big heavy boxes. Today TVs are thin flat and smart. We call them smart LED TVs. They connect to the internet to show videos and play games. Let us explore the technology behind these screens. 📺
How LED Displays Work
LED stands for Light Emitting Diode. An LED TV screen has millions of tiny pixels. These pixels are red green and blue. Behind the pixels there is a bright light source. This source is a grid of small LED lights. The TV controls the color of each pixel to show an image.
Here is the image display process:
[Video Signal Input] ==> [LED Backlight Illuminates] ==> [Pixels Filter Color on Screen]
This creates a bright and colorful picture. It uses very little electricity compared to older TVs. 🔋

🖥️ Screen quality depends on total pixels. Here is the resolution formula for 4K screens:

More pixels mean a sharper and more detailed image. It makes movies look amazing. 🍿
