Unfortunately, this has drawbacks and can wash out the colour of the other subpixels. To address this, LG started using a WRGB pixel structure - adding a white subpixel to try and increase brightness levels. The downside to OLED TVs is that they struggle to reach the same peak brightness as even an average backlit model, as each pixel is limited by its size in the amount of light it can produce and by energy absorption from the colour filters.

Because the image doesn't need to pass through an LCD matrix, viewing angles are wide, while the overall build of an OLED TV is thin and light because of its simple structure. Because each pixel is its own light source and can be completely blacked out if need be, this means that a bright pixel can appear next to one that’s black with neither impacting the other, creating the exceptional overall contrast for which OLEDs are rightly renowned.Īnd that's not the only benefit.
Unlike traditional LCD TVs, which rely on a separate backlight that’s then passed through a layer of pixels, each individual pixel in an OLED can take care of both brightness and image creation. This is then passed through a colour filter made up of red, blue and green subpixels. To produce an image, an OLED TV combines blue and yellow light from OLED sources to create almost white light.
OLED (Organic Light-Emitting Diode) is a type of display that uses an organic carbon-based film through which two conductors pass a current, causing it to emit light. (Image credit: Future / Ori and the Will of the Wisps, Xbox Game Studios) How does OLED work?
