/in /by

At IMID 2018 held in BEXCO, Busan, Korea on August 29, Kwak Jin-Oh, vice president of Samsung Display, delivered a keynote speech on the theme of ‘The Infinite Evolution with Display’. He emphasized “Display will be the key material to link to the smart world and the creation of a new world and environment will be accelerated.”

Comparing the evolution of living things with the evolution of displays, Kwak pointed out the direction of the next-generation displays such as ‘size diversity from small to large size, adaption in design inclusive of full screen and flexible, and convergence with other technologies’.

In terms of size diversity, Kwak said, “High-resolution displays that can feel realism in small and medium-sized area, and displays that can be immersed like a big screen in a movie theater in large area, are required.”

The design adaptation then was referred to design autonomy as one of the values of next-generation displays. He further emphasized the value of rollable and stretchable displays as well as foldable displays in small and medium sized displays.

Kwak said that Samsung is developing rollable displays as well as foldable displays that are currently attracting great interest. Unlike foldable display, rollable display requires consideration of the stress on the front of the panel. He commented “Because there are many things to consider such as the time when it is rolled up, and the number of times it is rolled and unrolled, the company is conducting research to solve them.”

He also introduced a stretchable display that can implement patterns freely, and explained that it is developing various structures using RGB pixel unit and stretchable unit to implement displays that have high reliability with low stress.

Mentioning about biotechnology at the convergence area, he pointed out that new fusion technologies need to be considered such as measurement of oxygen saturation by transmitting light to hemoglobin or changes in the wake up mode and sleep mode of the display depending on the melatonin change.

Finally, Kwak concluded that display is evolving to create a new society and environment, emphasizing that display is the key material to link between the individual and the smart world in the forthcoming 5G era.

One of the issues of flexible OLED actualization is acrylic’s vulnerability against lower temperature, and silicone is emerging as a solution. Meanwhile, Momentive is attracting attention with their promotion of silicone based InvisiSil.

One of the key encapsulation technologies for flexible OLED is TFE (thin film encapsulation) that laminates thin inorganic and organic films, used by Samsung Display. Of these, organic material is formed through inkjet OLED process using acrylic materials. However, acrylic organic materials are easily broken under 0 ℃, which leads to difficulties in producing flexible OLED using these. However, silicone based materials can withstand up to -40 ℃ and are considered strong candidate for acrylic replacement.

Momentive is a company that develops such silicone based materials. In SID 2016 (22-27 May), Momentive opened an exhibition booth and presented InvisiSil Snap Cure silicones. The InvisiSil Snap Cure systems can cure rapidly at room temperature without UV exposure.

Momentive explained that for flexible AMOLED panel to move past edge type and toward true flexible such as foldable and rollable, silicone is much better suited than acrylic. Furthermore, they added that silicone based materials have yet revealed any disadvantages compared to acrylic, and that it is in development for continued application to mass production.

Samsung and LG’s Shared Vision for OLED

/0 Comments/in , , , /by

On the first day of OLEDs World Summit (October 27-29) held in Berkeley, USA, Samsung Display and LG Display gave their talks back to back. Samsung Display’s Vice President Chang Hoon Lee and LG Display’s Joo Soo Lim discussed their thoughts on OLED under the titles of ‘The Future of OLEDs’ and ‘A Future Game Changer’ respectively.

Samsung Display’s Lee, who gave his presentation first, reiterated Samsung Display’s leadership position in the mobile market and how Samsung Electronics’ recent mobile display reflects this. Comparing RGB pixel structure and their own diamond pixel structure, Lee drew comparison between human eyes and diamond pixels; due to cell distribution in eyes, humans are more sensitive to green colors and that diamond pixels reflect this by having twice as many green subpixels as blue and red ones. The diamond pixels also maximize the sub-pixel packing and increases the PPI.

Regarding the advantages of OLED display, Lee gave 2 examples using Samsung Electronics’ latest smartphone models. Utilizing the fact that selective control of each pixel is possible in AMOLED displays, Samsung provided Vision Aid to help people with color blindness. OLED’s ability to achieve total black is used in Super Dimming function where screen brightness can be reduced to 2nits to be used in the dark environment.

LG Display’s Lim revealed that an adult in the US spends 9 hours 40 minutes a day on average looking at one form of display or another. Highlighting the need and importance of quality display, Lim also discussed advantages of OLED display over LCD such as total black, 3D effects, and color gamut.

As the future OLED display, Both Lee and Lim placed slightly more emphasis on flexible (plastic) OLED than transparent or mirror display. Samsung Display discussed requirements necessary for a successful flexible display in more depth touching on the need for suitable cover window, flexible touch (sensor), flexible encapsulation, and flexible backplane. On the other hand, LG Display discussed flexible display’s design freedom and its influences on the wearable, mobile, and automotive markets. Lim also placed much importance on how flexible OLED can be used in virtual reality display market. The 2 speakers ended their talks affirming the need for new display market and innovation through OLED technology and new applications.

The presentations given by the 2 apparent leaders in the OLED display industry were remarkably similar with both speakers underlining major points of OLED in broad strokes. The need for solutions for future OLED, whether it be flexible, transparent, or mirror display, through innovation and technological advances is an absolute truth if not maybe too obvious. There also may be some comfort to be had in the shared vision within the OLED community. However, it is also a fact that numerous attendees of the conference commented on the similarities of the 2 presentations and the lack of any surprises.
