More on Digital Display
Apparently, there's hardly anything today that does not have anything to do with visual and digital display. From the smallest thing like watches to something to super-sized digital signage in public places. Despite its different sizes, type, names or technologies in those displays, they have one thing in common: they live to deliver visual pleasures to your eyes in the first place before other extras such as displaying information and showcasing images. These days, there are many types of digital display and they serve different purposes as well. Some are designed for personal use like smartphones, tablets, monitors, and television. Others like digital signage and video wall are intended for commercial interests of advertising or selling products and services or simply brand/image building. When it comes to digital display and visual, most consumers usually expect a large and brighter display with vibrant colors. It is particularly true if you plan to use it for view rich graphics digital content such as watching movies or playing games. But certainly there also exist types of digital display which are 'more functional' in the sense of displaying digital numbers and texts.
But how does actually one display differ from another? Panel or display technologies is one of key factor that determine performance and thus affect your choices of display. Currently, there are three type of displays widely used and modified in the entire digital display industry: Plasma, LCD, and OLED.
OLED stands for Organic Light Emitting Diode. For big fans of smartphone and tablets, OLED is no stranger. In fact, they are closer than your imagination. The term AMOLED, which is very popular, thanks to the Korean electronic giant Samsung, is one example of OLED applications. OLED works pretty much like plasma with gases that emits light but in this case the light is turned on by the polymer. And because it directly emit lights, it can be made super thin and light than any other LCD. It also offer superb viewing angles and even more power efficient than LCD. Like plasma, it also poses excellent contrast but with much more faster response time. In short, you can say that OLED takes all the good traits of both plasma and LCD dislays and make it even better. Unfortunately, it's not all upside with OLED. It took quite a sum of money to produce them, saving for mass market. Therefore, OLED still got a bumpy road ahead. And although some of big display manufacturers has managed to rolls out some OLED display this year (http://www.extremetech.com/computing/145155-oled-tvs-at-ces-2013-the-wait-is-nearly-finally-just-about-over-probably), in the end it is the consumers that will be their final judges.
