High-end television set designs have become complex, hi-tech systems producing better and better quality as standard. Light-emitting diodes (LED) are a modern solution to lighting in LCD televisions. Liquid Crystal Display (LCD) TVs are LED-backlit, which is a system comprised of the backlight and the panel. The panel is made up of the LCD sheet that generates the individual, colored pixels but they don’t produce light so the panels are backlit, usually by LED lighting systems.
The more individually controllable LEDs there are in the backlit array, the greater the TV’s contrast ratio you get, providing sharper, high contrast. The consumer now has a choice of technologies, with LG offering organic light-emitting diodes (OLED) for superb quality viewing and Samsung rolling out QLED panels in its top-end television sets.
The OLED sets produced by LG are very different technology from LED-backlit LCD televisions. The OLED panels perform both functions, generating the image and illuminating it. They create a picture that doesn’t need an external light source. Each pixel in fact produces its own light, producing brilliant contrast, compared with the inferior LED TVs. Thisis expensive technology to produce in the larger sized, high-end television models. The cost reduces as the panel size scales down, as for high-end mobile devices.
On the other hand, Samsung has released QLED television sets which they claim are comparable in quality to LG’s OLED sets. However, the technology is strikingly different from OLED, with Samsung’s QLED designs being basically LED-backlit LCD televisions on steroids, enhanced with leading-edge, advanced technology.
While QLED televisions still rely on LCD panels with their LED-backlit arrays, the Samsung technological enhancements employ Quantum Dots in their LCD panels. These are nanoparticles that emit or alter light at different frequencies in reaction to electricity which creates more color precision. However, contrast isn't the same quality as the sharp levels produced by the LG OLED panels. To address this, Samsung treats their QLED televisions with a low-reflectivity finish and produce peak luminance. The Samsung QLED television set is almost as expensive as the LG OLED set.
While the two technologies sound similar, they are in fact significantly different. They both offer state-of-the-art, breathtaking viewing but you need to decide which technology you want when you purchase your next television set.
While their enhanced picture quality relies on different technology, both the Samsung and the LG high-end televisions set come with luxury features. The LG OLED and the Samsung QLED TV sets offer 4K resolution and both support HDR content. 4K is ultra-high-definition (UHD) and is the latest standard for TV resolution, displaying four times the number of pixels as older television models. They offer high dynamic range (HDR) video standards allowing televisions to display a wider range of light and color than standard models. Both the OLED and QLED models are connected, smart TVs to enable streaming
video services and applications and both designs will support all the main 4K, HDR streaming services. The only question that remains is which technology will suit you best?
