JOLED’s Intense Start, Mass Production is When?

At Finetech Japan 2015 (April 8-11, 2015), JOLED gave a presentation for the first time since its inception and drew much attention.

 

JOLED’s speaker Tadashi ISHIBASHI gave a presentation on JOLED’s target market and application technology under the title of “The Evolution of OLED Manufacturing Technology by JOLED”. During his speech Ishibashi revealed “JOLED’s target market is 10~30 inch mid-size OLED panel and ultimately to form new market through flexible display” and that “top emission, RGB printing, color filter, and ITZO backplane of self-align structure will be applied for key technology”.

 

Furthermore, by forming all RGB through solution process, macro-cavity effect via thin half-transparent cathode, and minimizing interference of other colors and external reflection using color filter, JOLED explained that high purity color reproduction is possible. It is analyzed that this means that they absorbed Sony’s characteristic super top emission technology. Backplane is top-gate’s TAOS (transparent amorphous oxide semiconductor) and Ishibashi added that it is also possible to reduce cost by minimizing investment amount by applying 5 mask self-align structure.

 

Regarding flexible display, JOLED used the technology that was applied to 9.9 inch qHD panel (revealed by Sony in 2012) which used white OLED and color filter as an example but reported they are currently developing technology to produce flexible display using solution process RGB.

 

From the presentation it is estimated that for JOLED’s mass production, Sony’s OLED panel structure and Panasonic’s RGB printing technology will be combined and applied. Although detailed investment timeline was not revealed, as mass production application technology and target have been publicly announced, investment in near future is anticipated.

LCD, Busy Playing Catching Up to OLED…

Following smart phone, other devices equipped with display such as tablet PC, monitor, and TV are mostly using OLED panel. In turn, LCD is attempting to replicate key points of OLED panel to catch up.
The first is LTPS TFT technology. When Samsung Display started producing AMOLED using LTPS TFT, it was overlooked by the LCD sector as it financially needed twice the amount of investment compared to a-Si TFT technology and therefore thought it to have no business value. However, as the smart phone resolution is getting higher, LCD companies are also employing LTPS TFT that has high mobility.
The second is the ultra slim thickness of OLED panel that does not have BLU. To answer the smart phone’s need for a thin body with light weight, LCD is thinning the panel by slimming the glass substrate further and further. Nowadays, even TV sector of LCD is busy trying to become thinner. In CES2015, Sony exhibited ultra slim LCD TV with thickness of approximately 4.9mm.

The third is curved design. LG Elec. and Samsung Elec. exhibited curved OLED TV using thinness of OLED panel in CES2013. With the products on the market, LCD TV also reduced thickness and began selling curved LCD TV.

Hisense, a Chinese brand, exhibited LCD TV with curved design in CES2015. Samsung Elec. decided that the main product of 2015, SUHD LCD TV, will have curved design, as well as releasing a curved LCD monitor. However, despite reducing the thickness LCD cannot yet be applied to smart phones.

The fourth is color reproductivity rate. The existing LCD TV can only produce approximately 80% of NTSC standard, which is limited compared to 110% of OLED. LCD sector criticized OLED’s color reproduction to be excessive; however, they recently developed new technology of applying quantum dot materials onto BLU and launched the sales of LCD TV with almost 120% of NTSC. Furthermore, it is deceiving the public by calling the QD BLU LCD TV as Quantum Dot TV packaged as a non-LCD TV.

The fifth is contrast ratio. OLED TV’s contrast ratio is close to infinite with 1,000,000:1. Compared to this, LCD TV’s contrast ratio was 1,000:1, and unable to showcase dark scenes. Recently, HDR (high dynamic range) technology that brightens bright scenes and darkens dark scenes is strengthening its contrast ratio. Sony is striving to achieve high contrast ratio for LCD TV, similar to OLED TV, and exhibited HDR technology applied BRAVIA in CES2015.

Many key points of OLED such as previously mentioned thickness, contrast ratio, and curvature ratio still need to be improved by LCD panel, and diverse attempts are continually being made to catch up to OLED panel that is entering the market with great strength. However, LCD cannot yet even attempt to match OLED on high speed response time that is needed for programs with fast action such as sports.

OLED holds diversity in color definition and design, and even if LCD keeps on reaching for these characteristics, LCD will remain LCD and will not be able to overtake OLED.

Sony, unveiled a high-resolution single-lens OLED module

This module was designed by Sony to be a small and light weight glasses-style composed of OLED microdisplay, micro-optical unit, and miniaturized control board.

It is the smallest display module as a 0.23-inch high-resolution (640×480) OLED microdisplay. The contrast ratio is over 10,000:1 with 100% sRGB. Generally the RGB stripe is used to secure the color purity, but this panel uses the optimized matrix configuration.

JOLED, the last bastion of Japanese OLED

140730612118The Innovation Network Corporation of Japan (INCJ), JDI, Sony and Panasonic have finalized an agreement on JOLED establishment by January, 2015 through an integration of OLED panel R&D organizations owned by Sony and Panasonic for mass-production, development and early commercialization of the OLED panel.

INCJ has 75% of JOLED’s voting rights. INCJ and JDI have agreed on making an investment in pilot line installation for mass-production.

 

JOLED aims to become a leading company in the OLED sector by collecting the technologies owned by Sony and Panasonic such as the OLED layer technology, oxide TFT technology and flexible display technology, and converging with JDI’s mass-production technology.

JOLED plans to develop the OLED panels for application section first, including tablet PC, note PC and signage for mass-production of medium and large size OLED panels. A future target of JOLED is mass-production of the flexible OLED.

Sony unveils Head Mounted Display (HMD) for medical care

Sony displayed a system, which enables you to check endoscope video through Head Mounted Display (HMD) at International Modern Hospital Show 2014 held from July 16th to 18th, 2014. For the existing endoscopy surgery, posture restriction exists because the procedure requires external monitoring. With Sony’s new product, surgery, however, can be performed without the posture restriction.

This specialized product for medical purpose weights only about 490g which enables an operator to perform in a standing position. It doesn’t fully cover eyes of an operator by changing the shape of wearable belt so that the operator can visually check surgery device by lowering the eyes without taking it off.

This medical HMD is installed with Sony’s OLED display and shows images on the OLED display individually thus crosstalk is not that large and doesn’t induce dizziness during its use.

 Sony consulted with doctors to develop this system and said that demand for this competitive system will increase as 3D endoscope increases.

Skyrocketing interest of Panel makers in blooming smart watch market

Set makers are launching various smart watch products such as Galaxy Gear and Gear Fit by Samsung and G-Watch by LG after the smart watch by Sony. With this, display companies accelerate development and mass-production of panels for the smart watch.

At present, OLED, LCD and e-paper are the panels applied to the smart watch. Also the flexible OLED is preferred for the wearable smart watch. Samsung Display is currently mass-producing the flexible panel for the smart watch, and LG Display will also start to manufacture them in the latter half of this year. Futaba of Japan has completed the development of PMOLED for the smart watch panel, and AUO introduced an ultra-thin OLED panel showing its at SID 2014 will to enter the panel market for the smart watch.

Shipments for the world’s smart watch market in 2014 are expected to 7 million but Apple Inc., aims to sell 9 million products in 2014. Thus, the smart watch market is a business with high potential to grow explosively and is where fierce technology competition will be between the panel makers.
