If you watch an OLED and compare it to your experience with another kind of TV panel, you'll notice blacks are just that: actually black. Compared to the soupy greys of most LEDs, there’s no comparison. If you regularly watch content in a dark room, OLED is king. Combine these inky blacks with the bright whites OLED panels also produce, and you're left with a fantastically vibrant image.
LG and Panasonic, the most consistent producers of OLED televisions on the market, like to use the term "infinite contrast" to describe how the self-lighting pixels switch off completely when reproducing black; giving it an "absolute" black color instead of a "relative" black that only describes how dark one pixel can get compared to the brightest pixel on the screen.
The advantages of OLED go beyond simple static image quality. OLED panels are hugely responsive, meaning PS5 and Xbox Series X gamers and home cinema aficionados are going to absolutely love OLED TVs.
OLED panels are capable of a refresh rate of as low as 0.001ms, which for reference, is around 1,000 times faster than a standard LED-backlit LCD panel, while also being superior to the now-discontinued plasma tech.
And, because the lighting source they use is so tiny, the depth of screen sizes has shrunk at the same rate. That means OLED TVs have awesomely deep blacks and bright, peak whites, improved color accuracy, as well as responsive motion - and all from a form factor that's just a few millimeters in depth and lighter than many LED TVs.
