Flickering is a rapid and repeated change in brightness or color that is often seen in electronic displays such as computer monitors, TVs, or LED lights. It can be caused by various factors such as a fluctuation in power supply, a mismatch between the refresh rate of the display and the camera recording it, or a malfunction in the display hardware. Flickering can be distracting and uncomfortable for the eyes, and in some cases, it can even trigger headaches or seizures in individuals with photosensitive epilepsy. **

While both phenomena can cause variations in brightness, they are fundamentally different in their underlying mechanisms. **
