How does the television work?

Almost everybody watches TV, either in the morning, in the afternoon or in the evening. With all the shows you’ve watched, and advertisements you’ve seen, have you ever asked yourself how does the television work that you get to witness the shows and major events worldwide.

Like the other devices, it has its own way of transmitting energy waves that converts them into those images that you see on TV. Tracing back its history or evolution answers the question of how does the television work. Through the different works and discoveries made by the scientists, from Michael Faraday’s light and electricity, to Paul Nipkow’s scanning disk, Boris Rosing’s cathode-ray tube, Vladimir Zworykin’s iconoscope, etc., one can see how the TV’s design and functions have gradually evolved; it took more than a century but it was all worth it.

So, looking at its inside and outside formats, how does the television work then? What goes on inside the TV? Why is it that images appear and sounds emit from this device?

At first, the TV was a mechanical media, used as an information storage device. Later on, the modern TV came through the cathode-ray technology, then more advancement in electronic technology created the color TVs, and the High Definition TVs.

You may ask, how does the television work during the early stage of its development. Well, the concept of TV revolves on this: a wireless transmission of electromagnetic waves that are converted into acoustic and light energy so that the people watching TV can view it. In TV’s early stage, it was Nipkow’s introduction of the scanning disk that started the series of improvements and inventions on TV’s mechanical system. Through the scanning disk, images can be “broken down” using a sensitize photocell, this photocell transmits the image as a series of electrical impulses to a receiver, where it is converted into light and reflected to an identical disk which reconstitutes the image. Later developments resulted because of the advancements in radio, x-rays, and physics, leading to the creation of cathode-ray tube technology, which allows high-fidelity projection in reconstituting light information. It was further modernized through the iconoscope, which scans the image through an electron beam.

So, how does the television work? --- that’s part of the awesomeness of science and technology. It is through the effort of the creative and bright scientists that television continues to work with efficiency. As more advancement in technology is introduced, more developments will also be done to how the TV works.
