WOLED stands for White OLED and has been popularized by LG. WOLEDs feature four subpixels: red, green, blue, and white. WOLEDs do away with the individual emitters for the red, green, and blue filters, and rely on a single layer that emits white light. The white subpixel doesn't have a filter, so it lets the white light from the emitter pass through uninterrupted.
