As cloud computing continues to advance, active matrix organic light emitting diode (AMOLED) display technology will play a vital role in influencing innovation in smart devices. This was the main thrust of the keynote speech of Kinam Kim, CEO of Samsung Display, at the recently concluded Display Week 2013.

Kim said that the future of displays will change considerably, with special attention to be given for the number of imaging possibilities in AMOLED. He emphasized that three evolving environments are likely to make displays the central focus of the increasingly pervasive use of electronic devices.

The first environment is the growth of the cloud computing environment wherein the capability of electronic networked devices for data processing and storage will be extended, allowing users everywhere to easily access content that only highly advanced devices can fully process today, including ultra HD (3840 x 2160) images and 3D games. Higher levels of display technology will be required to support users' increasing reliance on the cloud.

The second environment is the accelerating evolution of high-speed networks. By 2015, the velocity of 4G LTE will rise to 3Gbit/s, so the transmission time for a two-hour UHD-resolution movie will be under 35 seconds. Kim said, "As image quality of video content improves, larger and even more vibrant displays will emerge as a key differentiating point in mobile devices."

The third environment is the spread of connectivity among electronic devices. As the use of Wi-Fi networks widens, the N-Screen era is on its way. A massive network environment will be established by connecting not only smartphones and tablet PCs but also automobiles, home appliances and wearable computing devices. Due to this explosion in "data flow," there will be a surge of interest in touch-enabled displays.

One major advantage of AMOLED displays is that it can embody true colours closest to natural colours with their colour space 1.4 times broader than that of LCD displays. By offering a broad colour gamut – supporting nearly 100% of the Adobe RGB colour space, AMOLED will expand the range of displays well suited to printed media, where specialised colour is frequently required.

Another advantage is its flexibility and transparency. AMOLED displays can maximise portability by making devices foldable and rollable, and they can also lead innovation in product designs with advantages in curved forms, transparent panels, and lighter weight than other display technologies. AMOLED displays are also responsive to touch and sensors for detecting all five human senses.

Kim went on to say that display applications, with advantages of AMOLED technology, will rapidly spread throughout other business sectors like the automotive, publishing, bio-genetic and building industries.

In the automotive business, AMOLED displays will replace conventional glass and mirrors that have been used for digital mirrors and head-up displays. Capitalizing on their advantages with flexibility, durability and high resistance to temperature changes, AMOLED display panels also will be used for watch displays and for products in the fashion and health care market sectors. Further, in publication and building, AMOLED displays will set the trend for the building market sector with AMOLED architectural displays in and outside buildings being used as highly desirable decorative and information-delivering products.
