We all know how a television works, right? Well, for those who do not know, the TVs turn on and off small colored lights in the form of pixels to create those moving images. In the case of old tube TVs, this is done by way of rendering images from top to bottom, the wonderful thing is that it is at a speed that the human eye is not able to perceive.
Well, that was roughly the theoretical part, which is somewhat simple to understand. Now we are going to practice, which is where it gets interesting, since we have rarely been able to see how the operation of a television, whether new or old, really works. Fortunately, we have the guys from The Slow Mo Guys, who in their most recent video show us in great detail something that few of us have ever had in our lives.
The magic of super-slow television
I imagine that many know Gavin and Daniel from The Slow Mo Guys, since today it is one of the most famous YouTube channels thanks to its incredible experiments using very expensive professional cameras capable of capturing images at an impressive speed.
In the most recent video we show the differences between an old cathode ray tube television, a huge 85-inch LCD panel with 4K resolution and an OLED TV. All this using one of its cameras that is capable of displaying images at 380,117 frames per second. And as you may have imagined, the result is truly amazing.
As we will see, the video is not short to have a duration of more than 11 minutes, and although the explanation is quite detailed and interesting, it is in English, so some may find it unattractive. But if you want to bypass the explanation and concentrate on the images, you can see up close and in a super slow camera how these televisions work.
The most impressive has been the tube TV with ‘Super Mario’, because for the first time we can see in detail the scanning line working on creating the image that our eyes are not able to perceive. This line is responsible for creating the image at a speed that is impossible to detect, and to understand it better, in the video we show it gradually, increasing the speed of the camera until we reach 380,117 frames per second.
Already in the case of LCD and OLED TVs, they focus more on showing us what their technology consists of and not so much on speed. This is done through a Macro lens that lets us see the light emitting diodes organic and independent of the OLED and the difference with the panel always on the LCD LED.
Undoubtedly a good way to understand how the evolution of televisions has been and the differences between the most popular technologies today.
