Breakthrough In The OLED TV Technology – Your Oled Can Now Be Even Brighter Than Before


As the years have passed the technology has evolved and this change has always been to our advantage. So we have all seen and heard about LED screens and even LED TV but there is a new technology for TVs called the OLED TV. So what exactly is this new technology? How exactly does this new technology work? What is the difference between LED TV and OLED TV? I know you must be having a lot of questions so why don’t I begin to sort them out. 

To have a better understanding of OLED TVs, let us first understand LED TV technology. An LED TV is made of three main components: LED-backlit diodes, liquid crystals and colour filters. So when we turn on our TV, these diodes get electrically charged and produce light. This light then passes through the liquid crystals layer and an RGB colour filter which is made of small individual colour pixels and are capable of reproducing colours and that’s how we see pictures on our screen. 

Now for OLED technology, an OLED display follows the same principle as a LED display but operates the only difference between the two is that the LED panel requires a dedicated backlighting setup to produce light. However, an OLED panel can produce its own light. All this is possible due to specially constructed OLED diodes. 

So with such a minor difference between the two, why have people started to prefer OLED TVs to LED TVs? And what makes OLED TVs so much more costly than LED TVs? Well, OLED technology brings a lot of advantages along with itself like higher contrast levels as an OLED display can individually control its pixels, the pictures produced on an OLED TV have a deep vibrant colour, unlike any other television. They also have wide viewing angles as an OLED TV as the distance between pixels and the surface of the screen is nearly non-existent. And they also are thinner and flexible but these are just the pros. What about the cons? As we all know that a coin has two sides so what about the disadvantages of this OLED TV. 

So there was a problem related to the dim brightness in the OLED TV technology which led to problems in energy efficiency and battery life in the OLED TVs but that was only until now. 

Researchers at the University of Michigan claim that they may have been able to resolve the  OLED’s dim brightness problem, with the invention of a new electrode that can release 20% more light from respective screens at the same time as increasing energy efficiency and improving the battery life of the OLED displays. The electrode is designed to effectively improve the emission of light from an OLED screen’s diodes. This was known from the blog post on the University of Michigan’s website stating that “the approach prevents light from being trapped in the light-emitting part of an OLED, enabling OLEDs to maintain brightness while using less power” and goes on by stating that “this could go even further as we are able to free up about 34% of the light by using unconventional materials with special emission directions or patterning structures” and even claims that “Industry may be able to liberate more than 40% of the light, in part by trading the conventional indium tin oxide electrodes for our nanoscale layer of transparent silver,” this was said in the blog post by  Changyeong Jeong, who is a PhD candidate in electrical and computer engineering and a part of the research team of this breakthrough of OLED technology.
