why can you not look at a welding flare with your bare eyes but can look at it on tv without eye protection?

The image on TV is not a welding flare. It’s just a bunch of TV pixels lit by an LED backlight, changing their brightness in coordination to present the *illusion* of a welding flare, based on data recorded by a camera when it looked at a real-life welding flare.
