OLED displays are not raster or scanning displays. Instead, they use an array of organic light-emitting diodes (OLEDs) to generate light. 

Unlike LCDs, which block light to create an image, OLEDs emit light when electricity is applied. OLEDs can be used to create displays of any size or shape without the need for backlighting.
