Organic Light Emitting Diodes (OLED) Finally Comes to Laptops
We cannot deny that the laptop displays are sometimes awful, and we have been dealing with it for the longest time. It is undeniably true that the best laptops were sold these days, and their resolution has been developing. However, the contrast and spectrum of an average laptop are woeful.
For the very first time after several years, we are about to witness a major revolution in the quality of a laptop display. Take note that this is not just about Ultra HD that swiftly became conventional, but also a newest picture technology that any adherent of the top-of-the-line televisions will be familiar with and we called it OLED or Organic Light Emitting Diodes.
Conceivably, you may think that you have a better screen quality when you own an Asus Zenbook or a Dell XPS 15. Compare to other laptops, you are correct. However, each laptop has the same flaw, their backlight.
In a usual LCD panel, the crystals turned to channel light to create an image. However, they do not generate light of their own. The picture will become visible only because of the light that comes on its screen that bright through its LCD panel. It works with that, but it also means that it is not possible to have a seamlessly dark image. To some extent, the light is always on. The process is not the same with OLED. It made of pixels that produce its own light instead of liquid crystals, and it doesn’t require any backlighting function. The basis of this latest technology is that when an existing flows in the middle of an anode and cathode, in between these electrodes is the emissive layer of the organic molecules that can be illuminated. To make it work properly, a conductive layer consists of organic plastic molecules like polyfluorene was placed in the middle of the anode and the emissive layer. The anode will form electrons that came from the conductive layer, which make it positively charged and will form electrons from the emissive layer. As a result, the light will be produced, and this is called Electrophosphorescence.
Contrast oscillates the quality of an image more than any considerable attribute. While some agree on precise color and perfect brightness, others are not. These elements can be measured by tools to check if they match with the required standards. A verdant plain that may look unnervingly real to the eye of one person may appear false and neon to another person. Perception is important.
Everyone believes that if the contrast ratio is higher, it is better. It actually defines the variation between the dark and bright and that’s an important part of the reality, but what will you feel if you open your eyes in a completely dark room? Of course, you will be terrified! How about if you attempt to look into the sun? You will hurt yourself. There is no man-made screened device that can clone the real world’s contrast, but the closer the display, the better it looks. This is mainly the reason why the OLED technology is vital, and finally, it reaches to the laptop.
So far, small notebooks like Alienware 13, 13-inch HP Spectre x360, Lenovo ThinkPad X1 Yoga and Samsung Galaxy TabPro have an OLED display. They all made up of 1,440 vertical pixels, but unfortunately, they are all very expensive. Lenovo ThinkPad X1 Yoga’s estimated price will be $1,650, without any upgrades with the hardware. Many people won’t be able to afford OLED-based laptops this year; not even in the year 2017. Nevertheless, we should remember that when a certain company seizes the chance of introducing latest technologies, it’s no doubt that other companies will follow. Toshiba first introduces the Ultra HD feature on their laptop in the year 2014. More than a year later, several top manufacturers included a 4K panel on their laptops. The PC business’ tight margins can be able to make it tough for high-priced technology to establish a foothold, but once they do, it will definitely spread like wildfire!
