Television

✨ The magical window

A television is an electronic device that receives and displays audiovisual content, such as programs, films, news, or live broadcasts. Modern televisions usually use a flat display made from millions of tiny pixels that produce different levels of brightness and color. Depending on the technology, the screen may use liquid crystals with an LED backlight, or individual light-emitting elements such as those found in OLED displays.

The television receives information through sources such as an antenna, cable, satellite connection, or internet network. An internal processor decodes and organizes this information so that images and sound can be reproduced. A remote control or physical buttons allow the user to change channels, adjust the volume, select inputs, and access other functions. The image on a television is created by rapidly updating the pixels on the screen.

Each pixel can display different colors and brightness levels, and together millions of pixels form the complete image perceived by the viewer. Sound is produced by speakers that convert electrical signals into vibrations in the air. In digital television, the original audiovisual information is encoded into data that can be transmitted efficiently and then decoded by the device.

Smart televisions can also connect to the internet and run applications for streaming, browsing, or other services. Although television technology has changed considerably over time, its basic purpose remains the same: receiving audiovisual information and converting electrical or digital signals into images and sounds that people can perceive.

💡 Did you know?

Did you know that the first televisions didn't have colors? Everything was in black and white! People had to imagine the color of the actors' clothes. The first color broadcasts arrived much later, in the 1960s. It was a true revolution, as if the whole world had suddenly lit up!

Before having remote controls, you had to get up to change the channel! You turned a large knob directly on the television set. Often, there were only 2 or 3 different channels. Today, you can choose from thousands of programs just by pressing a button from your sofa. What a luxury!

Why do we call it television? This word comes from the Greek 'tele' which means 'far' and the Latin 'visio' which means 'see'. Therefore, television literally allows us to 'see from far away'. It's the perfect name for this object that shows us what is happening at the other end of the Earth!
