[iMiD 2017] LG Display, Spur Development of 77 inch transparent flexible OLED

/in , /by

LG Display’s Kwon Se-Yeol senior researcher introduced the 77-inch transparent flexible OLED which had been introduced in June at IMID 2017 held in BEXCO, Busan on Aug. 30, and announced the applied technologies to realize this.

Kwon Se-Yeol senior researcher mentioned, “OLED is self-luminous, so it can be manufactured with a thin thickness because it does not need a back light unit. The thinner the thickness, the more flexible the OLED can be so that it is easy to implement flexible displays with OLEDs.” and forecasted. “It can be used in various fields such as signage and smart desk.”

The 77-inch transparent flexible OLED which is released this time is a top emission type for improved luminance. The transparent thin film encapsulation layer is applied, different from the conventional OLED TV or large flexible OLED, and two polyimide substrates are used.

Kwon Se-Yeol senior researcher said “We applied a transparent thin-film encapsulation layer instead of the existing metal encapsulation layer for the top emission method ” and explained “A white OLED light emitting layer and a color filter layer were formed on two polyimide substrates and cemented together. A barrier film and a multi-barrier were applied to the top and bottom of the polyimide substrates to prevent moisture and oxygen penetration.”

The Kwon Se-Yeol senior researcher then states that “flexural rigidity of the panel is mainly affected by the thickness of the polarizer and the encapsulant layer, so it is necessary to reduce the thickness in order to improve the flexibility”, and emphasized “By reducing the thickness of the encapsulant layer from 100 μm to 20 μm, we can reduce the strain on the OLED module from 0.36% to 0.21%, along with improved flexibility”.

In addition, he mentioned that surface reflection due to polyimide birefringence phenomenon, laser wavelength selection according to polyimide properties in LLO (laser lift off) process, and use of flexible OLED module are all covered, and technical development is continuing.

Meanwhile, LG Display has developed the world’s first 77-inch transparent flexible OLED with UHD (3840 × 2160) resolution, transmittance of 40%, and radius of curvature of 80R as part of the national project.

[iMiD 2017] AP Systems, Find FMM answers through USPL

/in , , , /by

At iMiD 2017 in BEXCO, Busan on 28th, AP Systems announced that it succeeded in developing 1000ppi FMM with USPL (ultra-short pulse laser).

Since FMM plays a role of depositing pixels and RGB organic materials, FMM serves as a factor that determines resolution and yield of OLED. At present, FMM is mainly manufactured by etching method. This method has a problem that a shadow phenomenon due to the precision, thickness, and weight of the fine pattern occurs, in order to solve this problem, various FMM manufacturing processes such as laser processing and electro-forming have been developed.

Among these, laser processing method has an issue of forming burrs around pin-holes due to the thermal effect caused by laser irradiation. These burrs increase the shadow interval of the FMM, which causes overlapping of patterns during RGB organic deposition, thereby degrading the resolution of the OLED.

AP Systems has developed a burr-free laser process that does not have burr phenomenon and further controls the taper angle.

The Burr-free laser process is a short-time irradiation of unidirectional pulses at a constant number of times, since the laser is not continuously irradiated, it minimizes accumulated heat energy and prevents burr formation. In addition, by controlling energy of the laser, it accumulates energy and forms taper.

In this way, AP Systems explained ‘they produced FMM with various shapes of fine pin-holes such as square, diamond, and polygonal shapes, as well as 1170ppi FMM’, and ‘’We also developed large-area FMM manufacturing equipment with USPL method’.

AP Systems also added ‘multi-beam and USPL is equipped for FMM manufacturing equipment so that it can improve productivity and realize UHD’.

Since the launch of the Galaxy Note4 in 2014, the OLED resolution has remained at the QHD level yet. In order to manufacture an OLED having a high resolution (UHD level or higher), it is necessary to solve various technical problems faced by FMM. Accordingly, it is noteworthy how USPL technology of AP Systems will affect the future OLED market.

/in /by

UBi RESEARCH held ‘An Analytical Seminar on OLED Market Entry Feasibility of QLED and Solution Process’ on the 14th at Seoul Small& Medium Business Center.

CEO Lee Chung-hoon of UBi REARCH said “OLEd TV will show 16.7% market share in 2016 at the world premium TV market, and lead premium TV market with 68.1% share in 2020.” and analyzed such like “LCD TV could not follow OLED TV performance excluding low price and high solution.”

China is threating domestic LCD market in current wide TV market while displaying material superiority to LCD industry, and cost-effective rate of the wide TV is losing ground to Chinese products too. Thus, LG Display and LG Electronics did successful market entry after having equipped with competiveness in the premium market through OLED TV, and they are expediting mass-production investment and technical development aiming at dominating and popularizing premium TV market.

The most important factor in popularizing OLED TV is price. ASP (average sales price) of UHD OLED panel based on second quarter of 2016 is USD 720, and FHD OLED panel is approximately USD 450. It was expected that UHD OLED panel could lead TV market if it secured about USD 500.

Development to adopt solution process methods has been progressed in order to lower price of wide OLED panel in the industry, and QLED technology as an alternative of OLED TV is becoming an issue nowadays.

In relation with this, CEO Lee Chung-hoon forecasted like “As much as being closed to commercialization due to development of solution process OLED or QLED technology, WOLED technology becomes to be developed one step more, so market entry of solution process OLED and QLED will not be achieved easily. Specially, there are many technical issues in QLED which is considered as next OLED by Samsung Electronics, and 10 years of research will be required further.”

Also, he emphasized that the technology of being able to reduce cost vs. WOLED such as lessening layer numbers dramatically etc. should be developed in order to enter solution process OLED and market successfully, and the entry shall be made by targeting low-end market. In particular, he analyzed that WOLED would lead premium TV, and solution process QLED and QLED occupy the low-end market after 2020.
