LG as the first manufacturer to launch OLED TV, what is WRGB four-color OLED display? On the basis of the traditional RGB based on Red, Green and Blue, LGOLED TVs add white light spots, each pixel is composed of four color light points.
Due to the addition of white pixels, LG OLED TVs have the ability to express different grayscales and light and dark contrasts. This effectively solves the problem of color aberration that cannot be avoided by TV products that only use RGB three colors. We all know that the human eye has three color cones, and all the colors we see come from the combination of three cell pairs of colors. The four colors of WRGB can bring more combinations than human eye cones, thereby bringing a color gamut beyond the recognition range of the human eye, which is the more brilliant and realistic color of the LGOLED TV.
