OLED Technology: Why it is the future of all your gadgets
Tech companies all over the world have been swooning over the revolutionary OLED technology. You must also have noticed and possibly wondering why tech magazines, electronic’s manufacturers among others have started practically worshipping OLED. Keep reading to find the answers to everything OLED. To understand the concept, imagine a television that is 80-inch wide and quarter of an inch thick. What if you could roll it up and carry wherever you go? Would you like flexible cell phones? Or a gadget that consumes considerably less power than the ones you have? All of this is only a few of the things that can be a reality with OLED. Now, let us take a closer look at the technology to understand it better.
What is OLED?
OLED stands for Organic Light-Emitting Diode. In simple terms, OLED are minute solid-state devices that are made with organic compounds, which light up because of the movement of electrons through them. You can control the electricity to each OLED and either light it up or switch it off. Unlike LEDs, the OLEDs are so miniscule that they can be used as individual pixels on screens. They are very thin and flexible too. What makes them truly exceptional is that, since each pixel lights up independent of the others, it is highly reliable.
A screen’s ability to produce quality pictures is highly dependent on its ability to produce deep shade of black. Screen capable of producing such blacks can manage rich colors, high contrast, and brilliant pictures. In this respect, OLEDs are a league ahead of LEDs. While LEDs struggle to produce dark blacks, OLEDs can go totally dark when they do not receive electricity. Actually, OLEDs produce deep dark blacks, unrivaled by any other technology. OLEDs can also produce a multitude of colors more than the LED screens – that is to say that, they produce many more shades of true picture colors.
OLED screens take up about 0.2 – 0.3 mm in width, which is 10 times less than that of LCDs. They are not only paper-thin, but also light as a feather, which makes them easily portable. These characteristics allow the manufacturers to design screens that are 80-inch wide. The same features allow OLEDs to be installed on smartphones, tablets, and laptops.
Other User-Experience factors
The OLEDs are light emitters, unlike LED/LCD TVs which block light. Because of this, the images on OLED screens are visible over far wider angles. Further, they take much less time to refresh compared to LCDs. This translates to minimal blurs during fast-motion scenes such as action movies or sports. An additional delightful characteristic of OLEDs is that they are incredibly flexible. As such, Samsung and LG, have already used OLEDs to create flexible cellphones.
Perhaps, this is the Achilles heel of the present OLED technology. The organic compounds used to create OLEDs degrade four times faster than the LCDs or LEDs. The compound used to create blue pixel is especially prone to faster degradation, resulting in the color distortion of other pixels. Manufacturers currently use various workarounds to overcome this issue in their devices. However, these are temporary solutions and a more permanent solution is yet to be found. Further, unlike LED/LCD technology, the OLED technology is not yet time-tested for its reliability.
Even with some challenges facing the technology, OLED has been nothing short of revolutionary. Labs across the world are already working on methods to harness it remarkable capabilities in numerous ways. The day is not far, when futuristic objects such as electronic newspapers, magazines, books, clothes, wall paintings, and so on, will become a reality, thanks to the paper-thin, lightweight technology, OLED.
