A Place for OLED Unification

A place for OLED unification was held for Korea’s OLED industry which used to be divided. The two sides of Korean OLED industry, Samsung Display and LG Display, both attended the 1st OLED KOREA Conference, examining what lies ahead for OLED. This marks the beginning of future OLED display industry where worldwide OLED industry and Korean OLED industry are united.


The division within Korean OLED industry started when LG Display began to produce 55 inch OLED panel when Samsung was the only company that manufactured OLED panel. They each accused the other company of copying their technology and reported to the prosecution and thus the division was born. Last week, they both announced the end of legal disputes. However, although the trial for Samsung’s technology leakage has ended, the prosecution for LG’s technology is continuing. As this is a criminal case, the prosecution has to withdraw charges before it concludes.


In order to end the division within the Korean industry that began from Samsung and LG’s disputes, and to bring together worldwide OLED industry, UBI Research held the OLED KOREA Conference (April 2). 16 OLED experts from Korea, Japan, and China, including from Samsung Display and LG Display, forecast the future of OLED industry and discussed how OLED industry could succeed.


After the conference, approximately 40 industry-academic professionals attended VIP party and commented that the success of the conference was due to Samsung’s presence. Chang Hoon Lee who attended both OLED KOREA Conference and VIP party, and spoke with key speakers mentioned that Samsung will continue to be an axis for OLED industry and lead Korean and international OLED industry. The experts who attended the VIP event expressed hope that future OLED KOREA Conference would aid in the process of Korea, which is OLED device production oriented, becoming the mecca for OLED industry.

LG Display’s winning move, OLED TV Price

140627_LG D Workshop


LG Display (LGD) actively competes in TV market by reducing OLED TV price.

A department head Byeonggyu Roh of LGD emphasized “cost reduction of LGD’s OLED panel should be carried out across all processes and continued” and introduced its cost reduction strategy for the OLED panel for the 2nd Annual OLED Workshop held on 24th.

Key cost reduction strategy includes various ways such as investment cost reduction by rearranging the existing lines and modifying equipment; material cost reduction by optimizing the thickness of layers for TFT, the OLED and encapsulation; tact time improvement; and production efficiency increase by investing in M2 line. Also it was expected that soluble process will be the core technology for cost reduction in the future.

CEO of UBI Research, Choong Hoon Yi, said “LGD’s ultimate goal is to reduce the price by 1.1 times compare to LCD” and announced “cost down can be realized through reducing investment cost as 65” UHD OLED TV displayed at SID 2014 applied the existing co-planar to reduce from the previous 6mask to 4mask.”

LGD recently began supplying the OLED TV panel to China, and it plans to operate the M2 line in the latter half of this year. It also dropped the price of a 55” FHD curved OLED TV to $3,999 from the released price of $15,000 and a price war with the LCD TV is about to begin.

[SID 2014] Latecomers catching up aggressively

AMOLED latecomers; BOE, AUO and Tianma are rapidly catching up the AMOLED development of Samsung Display (SDC) and LG Display (LGD) at SID 2014.

BOE expressed possibility of investing in TV following mobiles by displaying 55” FHD AMOLED panel. In terms of technology readiness level, it is incompatibly lower than panels of LGD and SDC though, it is considerably fast that it was developed in six months and produced in a pilot line in Hefei.

AUO showed that its AMOLED technology had reached at certain level by unveiling 5.7” WQHD (513ppi) ultra-high resolution AMOLED panel. More attention drew towards AUO’s panel because its production method is RGB+FMM as SDC uses and the high resolution is realized with real RGB strip type rather pentile. AUO also expressed its will on AMOLED business by showing 5” HD flexible AMOLED panel and 1.6” AMOLED panel for a smart watch.

Tianma also unveiled 5.5” HD AMOLED panel. Its performance lags behind the current AMOLED panel, but it ai    ms to supply middle-end and low-end panel targeting mass-production of 5.5” FHD AMOLED through continuous R&D.

Challenges of Chinese and Taiwanese makers become serious in the AMOLED market, where Korean makers, SDC and LGD, are dominant, and the latecomers are about to invest in the sector. Thus, it is expected that the AMOLED industry will constantly grow.
