In other words, OLED displays can turn each pixel on and off independently, unlike LCD panels that have to be turned off and on in each zone. Sometimes bigger and sometimes smaller.
Because the pixels themselves have this light power, OLED screens are thinner than LCD screens and require fewer layers to build and function.
They are also capable of show purer blacks, Mainly because each black pixel is a dark pixel on OLED screens, which allows to improve the contrast compared to the rest of the pixels that we show on the screen.
by design, OLED screens are brighter than LCD screens and also more energy efficient. They also have another advantage, and that is that OLED screens can be flexible, although in return we get panels that have a shorter lifespan because their organic components break down.
These are the two main series of screens that can be found in the mobile market today. LCD screens, on the other hand, are more visible in the sun but are more expensive to manufacture and have “less blacks”, although they last longer thanks to the absence of organic components.
On the other hand, OLED screens have higher resolution, higher brightness, higher color saturation, lower power consumption, and are thinner. But in return, useful life is lost due to the decomposition of its organic components.
