Abstract WRGB OLED displays have more extra sub‐pixels to improve image quality than RGB OLED displays. This paper presents advantages of WRGB sub‐pixel structure in OLED displays by novel sharpening method which makes an image much sharper with less ringing artifacts. As a visual experimental result, the edges of images could be represented sharper and sharpening artifact was also reduced. In conclusion, the structure of WRGB sub‐pixel structure has advantages to enhance image quality.
