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.”

UDC’s New Technology, Improving lifespan and power consumption of OLED Display

UDC presented a paper on a new technology that reduces power consumption and increases lifespan than the existing RGB-FMM method at SID 2014.

Under the title of “Novel Two Mask AMOLED Display Architecture,’ the paper describes the new technology to reduce to 2 mask from the existing RGB-FMM using 3 mask. In details, each pixel is divided into 2 regions; yellow and blue, and evaporation is performed with the yellow and blue masks. This technology is to form a pixel structure of YRGB by developing a color filter of red and green on the yellow region

UDC describes that the technology reduces the resolution by 33% compare to RGB FMM, but the increase of the blue region will increase the overall lifespan and decrease the power consumption of the display. It also announced that it could lower the production cost by reducing tact time and improving yield rate.

Like UDC, the industry develops various technologies to reduce the yield rate and cost of the AMOLED, and further continuous development of the AMOLED is expected.
