Oculus Rift’s DK2 shipment just begins

Oculus, an American VR business, began shipment of the 2nd generation product, DK2.

According to OLED info, pre-order of DK2, the 2G product of Oculus, began in March, 2013 and 45,000 units were ordered by June, 2014. Ten thousand out of 45,000 units has been shipped on July 1st and the remaining will be shipped in the middle of August.

Oculus used LCD display for the first prototype but OLED display was used for the new product on the market. A video clip uploaded on Oculus’ homepage (http://www.oculusvr.com/) explicitly shows why Oculus used the OLED rather the LCD for faster response speed. Also replacing the LCD with the OLED greatly reduced motion sickness due to 3D while adding a positional tracking feature by mapping you movements with a camera and infrared light.

LG Display successfully developed world’s first flexible and also transparent OLED.

LG Display succeeded in developing world’s first flexible and transparent OLED.
LG Display announced the technological development of world’s first 18-inch flexible OLED and transparent OLED of same size, disclosing at the ‘national project workshop for transparent flexible display development’ to be held from July 10 till July 11.
It is considered that LG Display secured the foundation technology for developing a large screen transparent flexible display through the simultaneous development of flexible and transparent OLED this time.
The flexible OLED that LG Display developed is 18-inch in size with HD resolution (1200 X 810) nearly 1 mega pixel quality, and this is the largest OLED in the world, realizing the radius of curvature of 30R. This means it can be rolled up to a radius of 3cm with no operational complications and implies that it is possible to implement a large panel rollable TV over 50 inches in the future.
In order to realize maximum radius of curvature even on 18-inch screen, LG Display used Polymide film of polymer materials on a substrate that TFT and organic matters are deposited, reducing the thickness and increasing flexibility drastically.
Furthermore, this concurrently developed transparent OLED is of same size and resolution as flexible OLED and the transparency is 30% or higher realized by self-developed transparent pixel design technology. It is a radical increase of transparency, given that transparency of existing LCD based transparent display is about 10% or so.
LG Display maximized the degree of completion by lowering the haze caused by circuit element and film down to 2%.
The transparent flexible display is a national project of the future industry-leading technology development program promoted by the Ministry of Trade, Industry & Energy and the Korea Evaluation Institute of Industrial Technology, and LG Display is the leading participants of total 36 organizations of industries, academies, and institutes, aiming to develop a large 60-inch transparent and flexible display by 2017.
According to In-Byung Kang, Senior Vice President and Head of the R&D Center at LG Display, “Pioneered OLED TV market, LG Display is leading future applied technology of OLED,” and “Though there still are many challenges to be resolved, we are confident in developing transparent flexible display of over the 60-inch screen UHD (Ultra High Definition) screen with transparency of 40% and a curvature radius of 100R by 2017.”

By Choong Hoon Yi

 

The use of OLED is now expected to be extended from interior light and rear lamp to display of automobiles.

According to the display industry, LG Display (LGD) is negotiating with German automakers for plastic OLED panel supply. LGD ranked 4th in auto display market following Taiwanese Innolux, Japan Display and Sharp of Japan. It aims to take over the global market by reaching 1 billion dollars in sales based on the OLED display by 2016.

Most of major panel makers are currently focusing on leading the auto display market. At SID 2014, the major panel makers including Japan Display, Sharp, AUO and Tianma mainly showed displays for vehicles. LGD also reinforces targeting auto display market by integrating future technologies including transparent display. A fierce competition is ahead among major display companies.

The flexibility and durability; shock- and vibration-resistant, of the OLED as well as the fact that transparent display can be realized with it will accelerate its entry to the auto display market.

For auto rear lamp and interior light, the major OLED lighting panel makers including LG Chem. and Osram are developing the OLED and a new market is within the reach. If the OLED rapidly forms the auto display market, it will become a great cornerstone of the OLED industry along with mobile, TV and general lighting.140704_자동차산업
