A lot newer display technologies are starting to appear.
The newest technology microLED has indeed taken the limelight from OLED. And it is the perfect solution for the infamous OLED’s burn in issues and a much shorter lifespan compared to other display technologies. It is a lot brighter and a longer lifespan due to inorganic properties.
QLED on the other hand uses the traditional LED technology combined with LED technology to give out in return the best contrast and black level and greater brightness and provides the best contrast ratio.
