Magnets use to mess up all my screens. How can Apple put one in their phone, right next to the screen?
In: Technology
Phones use completely different screen technology than old TVs. Magnets used to mess up cathode ray tube (CRT) screens because those used a set of magnets to steer a single beam of electrons back and forth across the screen’s surface in the process of drawing an image. Modern screens use LCD or OLED technology, where each pixel is individually instructed on what it should display using an electric current, no magnets involved.
