What is an OLED?
OLED is a light-emitting diode built from thin films of organic electroluminescent material sandwiched between electrodes. Since the materials are luminescent, they produce light when the current is run through them. No other display technology creates light directly like this: LCDs use color filters and light-blocking liquid crystals above a light-creating backlight. Plasmas use UV light created by igniting pockets of gas to excite phosphors.
This means that OLED screens are thinner, lighter, more efficient and offer better performance and color quality than other existing technologies. Each pixel can be shut off, providing absolute black and amazing contrast ratio.
OLED televisions are the newest technology in the TV world. They deliver the best picture quality available today, outdoing LED LCD. But on top of being thinner, lighter and more efficient than other TVs, they can also boast a curved form.
Curved OLED TVs hold unique advantages. It can enhance the viewer’s immersive experience with its curved form, as the screen "wraps around”. The curved screen has a curved trajectory similar to a person’s ‘Horopter Line’ allowing the maintenance of a constant focus.
Another advantage of a curved TV is that the distance from the viewer is constant (unlike a flat TV in which the middle is closer than the edges). This means that in a flat TV there's a subtle image and color distortion which does not occur in a curved panel. The larger the flat screen and the closer the distance from the screen, the distortion becomes more noticeable.
A curved screen also feels larger and brighter compared to a flat TV. This, again, enhances the viewing experience. It is said that a viewer will feel that the size of a curved TV screen is larger than its actual size. Curved OLED TV also feels brighter because the light coming from the screen is focused on the center of the screen.
One final, and crucial advantage, is reduced reflections. The curved display elimiates reflections from ambient lighting on the sides, and it also reduces specular (mirror) reflections.
Nonetheless, voices arise arguing the disadvantages of curved OLED TVs: there is a claim that in order to get the benefit of a wraparound image, you need to be sitting in a pretty specific place. That sweet spot can be very small, possibly fitting only one viewer. Other faults arguably include limitation of viewing angles, elevated prices and, of course, looking less attractive mounted on a wall.
