Should you buy an LCD, Quantum-Dot or OLED TV?
LCD TVs, which require a backlight usually made up of white LEDs to show a picture on the LCD panel, are available in a wide variety of screen sizes and, thanks in part to the technology’s low cost of production, at affordable prices.
QLED (Quantum-dot Light-Emitting Diode), is known by different names among’st manufacturers. A QLED TV is an LCD TV but with a quantum dot coating over the backlight. However, the quantum dots (tiny semiconductor particles) in current QLEDs do not emit their own light. So QLED TVs, like conventional LCDs, rely on a backlight. The advantages of a QLED TV over a traditional LCD , is you tend to get brilliantly vibrant colours, plus bright, sharp and crisply detailed images.
OLED (Organic Light-Emitting Diode) is a panel technology that uses self-emissive particles – so there’s no need for a backlight. This allows OLED TVs to be unbelievably slim, while also offering convincing pitch-dark blacks, strong contrast, excellent picture quality above that of an LCD panel and superb viewing angles. LG, Sony, Panasonic and Philips are the big brands with OLED TVs in their line-ups and, broadly speaking, they’re far better than LCD type panels. New style OLEDS such as the LG EVO and Samsung QD panels are extremely bright.
