Do you know your phone's screen emits tiny flashes of light every millisecond to display images

Your phone’s screen doesn’t actually emit light like a lightbulb. Instead, it’s made up of millions of tiny pixels. Each pixel contains red, green, and blue sub-pixels that can be turned on and off individually.

These sub-pixels flash at incredibly high speeds, thousands of times per second. By rapidly switching these sub-pixels on and off in different combinations, your phone screen creates the illusion of a continuously lit image.

The human eye perceives these rapid flashes as a smooth, flowing image, allowing you to watch videos, browse photos, and read text on your screen.

This technology is called LCD (liquid crystal display) or OLED (organic light-emitting diode) depending on the type of screen your phone has.
