Brief explanation of QD OLED

QD-OLED means a combination of organic light emitting diodes (OLED) and quantum dots (QD). Blue OLEDs serve as the light source (backlight). An array of quantum dots serves as a color filter and ensures that red, green, and blue sub-pixels are created. Compared to white OLED (WOLED) panels, it offers advantages in terms of brightness, color range, and viewing angle stability, as Samsung also explains in a video on QD OLED technology.

The technology has its weaknesses.

Despite all the advantages, QD OLED screens also have disadvantages. When testing the Alienware AW3423DW, several editors noted unsightly color fringing when displaying high-contrast borders. The cause is the unusual pixel structure with green, red and blue sub-pixels arranged in a diamond shape.
