However, most LED TVs have a single backlight powering the entire LCD panel, and therefore aren't capable of rendering the deep blacks you can see on OLED TVs.
Since there's no need for a backlight, OLED TVs are thinner and have narrower bezels than those that use other TV screen technologies.
As a result, OLED TVs are capable of deep blacks, high levels of contrast, and realistic colours.
Ever since old-fashioned CRT televisions made way for flat-screen panels, the type of screen has been almost as important as the brand of TV itself.
As a result, QLED TVs have better colours and brightness than LED and most OLED TVs, but stop short of the contrast levels and deep blacks that OLED TVs offer.
