WOLED
Panel Types · 8 specs
Direct Answer
WOLED is LG Display's OLED TV technology, using white-emitting OLED subpixels combined with red, green, blue, and white color filters (WRGB) rather than individually colored OLED subpixels. LG launched the first WOLED TV, a 55-inch model, in 2013, and remains the primary manufacturer of large-panel WOLED, supplying other brands including Sony.

White Light, Then Color Filters
WOLED generates white light from every OLED subpixel and then filters it through red, green, blue, and white color filters to produce the final image -- the foundational white-OLED research is credited to J. Kido and colleagues at Yamagata University in Japan in 1995, well before any TV commercialized it. LG Electronics brought this approach to market first, launching the world's first 55-inch OLED TV in 2013 and expanding to 65-inch and 77-inch sizes the following year.
Samsung's early OLED TVs, also released around 2013, instead used individually colored RGB OLED subpixels rather than LG's white-plus-filter approach, but Samsung exited large-panel OLED TV production for several years afterward before returning via the different QD-OLED technology. LG Display remains the primary manufacturer of large-panel WOLED TV panels today, supplying not only LG's own TVs but other brands as well -- Sony's OLED TVs, for example, use LG Display-manufactured WOLED panels rather than Sony's own production.
