OLED stands for Organic Light-Emitting Diode. It is a type of light-emitting diode (LED) where the emissive electroluminescent layer is an organic compound film that emits light in response to an electric current. OLED panels emit their own light when an electric current is passed through them, unlike traditional LEDs that require an external light source. While OLED displays offer several advantages, such as perfect blacks, infinite contrast ratio, and wide viewing angles, they also have some downsides. Burn-in: OLED screens can suffer from burn-in, where static images can leave a permanent mark on the display. Shorter lifespan: The lifespan of OLED displays is generally shorter compared to other display types, especially for blue OLEDs. Higher cost: OLED technology is more expensive to produce than LCDs. Limited maximum brightness: OLED displays typically have lower maximum brightness compared to LED displays. Vulnerability to moisture: OLED panels are susceptible to water damage. Apple's tandem OLED (stacked OLED) design provides the benefit of brighter screens with higher contrast ratios that helps prevent burn-in due to the OLED panels not being pushed to their power limits.
