If you remember the incredible transformation of your TV from a big massive box to something hanging on the wall, Then things are going to get much better. Televisions have come a great deal in the past decade not only in size but also in technology. Traditional TV ‘Boxes’ are nothing compared to today’s LCD/LED TVs. And still, they are yet to evolve. Even your current Flat-screen LCD TV will look unwieldy compared to the next generation of products.
They technology that will let us accomplish this is called OLED, which stands for Organic light emitting diode. Televisions, Computer monitors, mobile phones, tablets and pretty much everything with a screen are set to become thinner than ever before. OLED is a major step on from the LCD technology that is currently used. OLED’s basic functionality is that it emits light whenever power is passed through it. OLED consists of a number of thin films made of organic materials placed between two conductors; as the current pass through it, the display lights up. This self illuminating function removes the need for the backlight that is an essential requirement for a traditional LCD screen.
Comparing two technologies – a 40 inch LCD TV needs a backlight large enough to span and light the entire surface of the screen evenly, whereas the same sized OLED TV could be a little more than an inch thick. And as the miniaturisation of the other components powering devices develops further, they will only continue to get thinner. Now, I know what you are probably thinking that OLED TVs must require more power to operate than LCD TVS. But you’d be surprised because without that backlight, OLED draw far less power than LCD. For devices that run on batteries, this is a massive boon. The final and the best benefit of OLED over any other technologies come in the form of a massive improvement in image quality. OLED consists of various layers and components. The basic working of OLED is fairly simple and can be explained like this: The current passes through the cathode layer to anode and as the current passes through the structure, electrons are added to the emissive layer. Electrons are removed from the conductive layer, leaving holes filled by the electrons from the emissive layer. As the electrons enter the holes they produce extra energy, which is emitted as light. The amount of light produces depends on the amount of power required.
We know that thinner hardware is only the first step in what this OLED technology can give us. Companies like Sony and Toshiba have created screens that measure less than half a millimetre thick, making them extremely flexible. Even folding a screen and putting a TV in your pocket could be possible with OLED technology. Just imagine a wearable television or a monitor. Making television a clothing accessory. We don’t know what is going to happen next in OLED technology. But we know one thing for sure that this is no longer a stuff of science fiction.
