Abstract
AbstractWe developed a patterning technology using photolithography that eliminates the need for a fine metal mask, thereby achieving high resolution across all red‐blue‐green pixels of an organic light‐emitting diode (OLED) display. Traditional methods using fine metal masks typically restrict the resolution and size of a display. However, the proposed technology largely bypasses these constraints. Suitable for OLED applications ranging from microdisplays in augmented reality and virtual reality to large TVs exceeding 80 in., our technology overcomes limitations on alignment accuracy, fine metal mask washing, and running costs and paves the way for mass production in OLED manufacturing.
