As OLED TVs are just around the corner, I'm getting to look into them more than before. There will be two kinds, RGB OLED TV by Samsung and White OLED TV by LG. WOLED sounds superior to me because it has one more color pixel besides red, green and blue. Seems like the more colors of pixels a tv has, the better picture quality it should have. Am I right? Need in-depth info from tv experts.
