Display Story1. Smart Revolution and Display's Importance

[ Original Page in Official LG Display Blog (Korean)] 

Recently I watched a drama got a background 20 years ago and I thought the world had changed with many things. Actually, It is unnecessary for comparing 20years ago. Just for 5 years, so many things have changed but these changes are not made by a need of people. These made needs for a people. I can illustrate a smartphone as a representative example. When I entered to a company, iPhone 3gs was just released and other gadgets were at the ready. Almost people seemed to be attracted at unprecedentedness of a smart phone rather than it was indispensable. In particular, It leaded a trend to be called an augmented reality application which can show weather information when you see the sky through a camera of smartphone. I would imagine interesting future through a new function of the smart phone and it has been realized with numerous developers. At now, it is unfamiliar to use a conventional phone and an indefinite future is going to walk in the real world through a smart phone.

▲ Smartphone and SmartTV

Pioneers drawn a image of future and users had absorbed a change with giving praise to an innovation. At present, we are living in the innovation which it was hard to be imagine 10 years ago. If It is ture that I feel like this just because of reaching old age, I seem to live in the best rapid change until now. This change which can be just a beginning used to be called the smart revolution. The reason of what the smart revolution was possible beyond smartphone to smart-TV, smart-watch and the internet of things is because there is a base on the number of revolutions. From now on, I want to tell based revolutions and the future of our lives in the smart revolution because there is a worth and roll of displays in the furure including a direction of my article.

What Make to be Possible the Smart Revolution?

These changes it is based on the smart revolution can be categorized like that user experience(UX) / IC of hardware / battery / communication / display.

▲ UX, AP, Battery, Communication, Display

UX : What smart phone becomes really smart is thanks to be able to operate many functions supporting conventional PC. The operating system(OS) getting bigger and bigger can be lighter by an optimization based on a compatiblitity of between hardware and application and the expandability among various gadget . At last, users can have been able to get PC' experiences through a small gadget. Becoming light is got other expression such as a time reduction for operation OS with application or power reduction for longer battery. Just becoming light don't include all revolutions. On this basement, it was added to multi-touch function called a revolution of UI and sensors such as GPS, gyroscope and etc, which takes an important roll of smart revolution. The user experience (UX) is built by combining aforementioned hardware basement and the big data.

Hardware component : The core value of success of a small gadget is miniature IC called MCU or AP which operates OS , image processing, memory controlling and etc. And it is thanks to advanced semiconductor technique and it results miniature ICs including memories and sensors as well as AP. Through combining an integrated IC, which is based on ASIC technology and semiconductor process called 'nano technique', it is to be possible to a smaller chip than a nail of human and it become based on changes . In here, combining sensors play really important roll to implement UX as on a small thing called smart gadget. 

Battery : The stable power system must be necessary for operating hardware and software.. And it has to be small, chargeable, durable to meet a condition of a small gadget. These were possible by developing lithium ion battery which gets high energy density and supports a charge and reuse.

Communication : At the center of the smart revolution, there were a progress of communication technique. WCDMA build an environment can communicate each other whenever they need it. Also WIFI made stable communication system in the home or office. At now, LTE's day is arrived and whoever can communicate high-capacity multimedia data using a small gadget.

Display : A cellular phone was possible thanks to development of TFT LCD which support display screen on the small device. And a smartphone which support full screen could be made by loading high resolution display. Thanks to the display, a gap of environment which users connect contents was decreased dramatically between mobile and PC.

How these contents are going to be changed

When the first concept of the ubiquitous computing was proposed by Mark Weiser at 1998, it meant "when technology recedes into the background of our lives" and it also meant "whenever, wherever, there is computing" which is possible to be every things on the internet. But the smart phone shakes a border of ubiquitous computing. At now, UX of the smart phone becomes on the each electronic machine and it moves future's one to the present.

How will have changed aforementioned categories of smart revolution? UX will be developed to the direction getting rid of a border between reality and virtual reality. It means that people can touch something, can feel surroundings and can control everything by their sense organ like real life in the virtual world. You can see many examples in the sense of a movie that computing natural gesture and moving a matter through just thinking about that. Presently, there has been many meaningful tries to implement future UX. From now on, it looks to be important to dear with getting data smartly from each sensor rather than making more sensitive sensors.

The hardware component is going to develop smaller and smaller and it will disappear from eyes. The high integration technology makes a performance users want despite of reduction its size as users can't see well. And on this component, a cloud computing technology was graft , which have made to reduce a burden of the hardware's performance. Surely, the performance is important, but it has been developed as that users don't recognize its differences comparing than battery performance's development.

▲ Intel Edison

The Intel announced a computer named 'Edison' which has small size according to a SD Card. And it looks to a finished computer because of operating based on Linux and offering Wifi, Bluetooth and etc function. It is representative example to show that hardware is going to disappear and it has sufficient condition to combine other small gadget. This combination called IoT(internet on things) makes needs of small computing.

The battery has been developed to reduce its size like the hardware component. A need of small size makes to advance low-power technique, a technology increasing battery life and wireless charging method. The battery is so important to be operated on the small thing, but aforementioned future example can be realization using existing power .

The communication has developed the direction operating faster and faster and keeping its communication state. And it requires advanced security technique and new communication system like LI-FI in the ubiquitous period.

Eventually I deal with the display. The display can be categorized in hardware like other component, but it has beed developed as other direction. The people requires its direction to increase size bigger and bigger because they want to see a vivid screen and want feel the reality. And it has advanced its appearance with curved, transparent and supporting 3D. It seems that display's final direction is what support hologram to feel like real-life.

Display Plays Important Roll in Future Technology

In brief, the direction of evolution will be proceeded to actualize the virtual thing and it makes feeling like in the real-life. Almost hardware has became smaller and it will disappear finally by results of advanced technology. But the display has a different tendency comparing other hardware above mentioned. The the display will be bigger and be other shape to give users experience like real-life.

Why did I give a long-winded explanation like aforementioned? The UX and display will have a shape can be felt like real after beyonding threshold of a change. Although the hardware and communication aforementioned are very important in the future, they will get a moment which its perpormance is over its need. And after this mement, these are hard to make a change got impact and it called just advanced specification rather than inovation. The battery has get a hurdle to be flexible, but it's going to be possible with many advanced tries at once. And it's going to walk a way like other hardware component. UX needs more experiences and technologies and its way to be a realization of virtualization. For developing UX, something has to be a prerequisite and it is just the display.

I think that the display's developemt play important roll to make advanced gadgets in the future. Already, so many media deals with the shape of the future and they have a common thing which is based on a display like transparent, curved or whole display of a wall.

Somethimes ago, I watched impressive TV-advertisement of a communication company which is not related on display company. The ad drawn future's image and it was look like future of the display company. As well as this ad, medias aforementined shown display's future. Actually, I majored a uniquitous system and its field closes software rather than hardware. But I selected a display which is near hardware's field because I belived the display will become the criterion can prove the future's development.

How Much Do You Know the Display

Todays, the display is always nearby you. The smartphone, TV, washing machine, refrigerator and other gadgets having some scareen have the display. TV have advantaged from CRT to PDP, LCD and OLED at now. The smartphone has became to get over retina display having high resolution. 3D technology has been developed to give more sense of reality and it has advanced to many image prossesing for displaying vivid screen. Also there is an effort to meet colors with eyes and there is so many agreement between from making a movie to displaying it.

You might heard a diffrence between PDP and LCD or see 3D dirving technology from some pages of internet . And you might come into contact many information about display's superiority or its future but you might be hard to know detailed information how it is possible or why this changes happend.

Although it can be difficult to know the display well, there are so many interesting story on the process to analize phenomenon and to follow traces. As mentioned above, since the display will be center of various inovations for making advanced future, it can make to afford much food for thought.

I Want to Share an Information of Display 

So I have a plan to give helpful stories for understanding the display to those who have interest and those who will have interest it. This contents divided with 3 categories which are issue , theory and future. The posting is going to fill these categories with new contents related on seminar or exhibition. There is an indefinite part in this plan as ever, but I beleive that its result which is steadily stacked make to guide advanced ways.

▲ Posting Plan

How much do you know the display? I am not an expert who knows everyting about display. But, I know the display how much more interesing it is. Fortunately, I am working in the company giving many chances to get various experiences related on the display. And on my work, I could get special experience with great co-workers and it will help you can understand easily and get interesting.
