Just under a month ago, we found out the latest news and highlights of the Consumer Electronics Show in Las Vegas; it’s a place where companies from around the world can show off their best technological products that will be released to the public. There were some brilliant products at this year’s show, but there was one piece that we at Electronic World were extremely excited about… The QLED TV.
Samsung unveiled their latest class of televisions that contains three televisions: the Q9F, the Q8C, and the Q7. But what is so special about QLED TVs and how do they work?
What is a QLED TV?
QLED TVs are televisions where quantum dot light-emitting diodes, or QLEDs, produce their display. Quantum dot light-emitting diodes are able to provide a clearer, brighter, and more efficient light compared to other forms of LEDs, such as traditional LEDS and organic LEDs.
How do QLEDs Work?
QLED work using the principle of quantum dots. Quantum dots are incredibly small particles that are nanometres in size – that’s 1 billion times smaller than 1 metre! In semiconductors, quantum dots are incredibly important, because they can be used to produce electromagnetic radiation or light.
In semiconductor physics, there are two important particles; electrons and holes (‘positively-charged’ electrons). When these particles combine, the combined energy is normally emitted as light, which is known as fluorescence.
In different types of semiconductors, the energy can be small or large, which can result in light waves of varying wavelength, which can provide coherent, intense light. The first application of this technology was in laser physics, where scientists developed quantum dot lasers. However, engineers in the technology sector have developed this to use quantum dots to produce light that can act as a display itself, as opposed to using a standard LED as a backlight.
How Good Are QLEDs Compared to Other LED Technologies?
QLED are said to be the next big thing in the television and technological industries, however, it can be difficult to surpass the recent surge in OLED TVs. The main benefits with QLEDs over other forms of LEDs is that the colour of light that they can produce can be switched incredibly easily since the colour of light produced is directly proportional to the size of the quantum dot.
Currently, QLEDs are so efficient that their efficiency is more than twice as much as the current highest value and it is incredibly close to the theoretical maximum of a thin-film LED, which is exceptional.
However, there is major competition between QLEDs and OLEDs at the moment when it comes to efficiency, popularity, and brightness. Currently, QLEDs are able to produce brighter colours compared to OLEDs, but OLEDs have been around for a lot longer, meaning that their efficiency is roughly the same, and in some cases larger, than QLEDs. However, time will tell when it comes to which one will be more popular throughout the year.
This brand-new technology is incredibly exciting to see, especially with the newest filming technologies being introduced. All we can say is that we are incredibly excited to see what will happen during 2017, so make sure you check out our blog with the latest news and updates.
