This is what happens on the TV screen at 380,000 frames per second

Do you know how the TV screen displays images? The Slo Mo Guys YouTube channel used high-speed video cameras to record what happens on the TV screen at 380,000 frames per second, after watching their videos, you will understand how the TV works.

With the 'antique' CRT TV, you can see every scanning happening, the way it recreates images at 380,000 frames per second, which is hard to see in current TVs. Great with high frequency sweep.

In the video, we can see, the image is displayed on the top, from left to right. When shooting the TV close-up, each red, green and blue (RGB) sub-pixel appears very clearly. These colors will alternately turn on and off to create millions of different colors. In fact, the white color you see on TV is created by a collection of many red, blue and blue sub-pixels. And the moving images on the actual screen are still sub-pixels.

For LCD screens, when displayed in black, these pixels will not display color but the backlight stays on, so when zooming close you can see that each pixel is still colored when displayed in black. But with OLED screens, no backlighting is needed, each pixel has its own display capability, so the pixels turn off completely, giving a deeper black color.
