The terms QLED and OLED refer to two screen technologies that could hardly be more different. Both technologies are closely related to one manufacturer. OLED screens for televisions were produced exclusively by LG for a long time, but other manufacturers now also offer OLED televisions, such as Sony, Loewe or Philips. You can find QLED screens at Samsung, Hisense or Tcl. Read the technical differences between QLED and OLED and the advantages and disadvantages of the technologies here.
QLED technology is said to be the best that LED screens have to offer, because they are considered to be particularly color and high-contrast LCD televisions. It is a further development of LCD screens with so-called “quantum dots”, which give the name the Q. LCD stands for “Liquid Crystal Display”: electrical impulses change the orientation of the crystals and the amount of light they let through can be varied. Different colors are created in this way. Since the crystals do not shine themselves, the so-called backlight (background light) is required. The light is generated by LEDs, which give the LCD TV the name LED TV. The further development to QLED televisions mainly concerns the backlight, because with QLED televisions another layer, the quantum dots, is placed over the already existing LED filters. They ensure that the TV can display brighter and more color-intensive images.
There are now several manufacturers of QLED TVs, but Samsung is particularly well known and popular. The manufacturer advertises that the QLED devices from Samsung with impressive computing power and artificial intelligence can scale the image up to impressive 8K. However, the 8 K-capable televisions are expensive to buy. If you are looking for a good entry-level QLED television, you should get one Samsung Q60R look at. The TV has the QLED technology and should convince gamers with a very short latency. The ambient mode should adapt the TV comfortably to the environment. The Quantum 4K processor is supposed to continuously optimize image and sound with the help of artificial intelligence. In addition, the smart TV can be controlled via voice command, it is compatible with Alexa and the Google Assistant.
