China's first flexible semiconductor industry base project release, has the exclusive technology

The following is a sponsored post by Shaanxi Kuntech Semiconductor Technology

The press conference for the landing and launching of Shaanxi Kuntech Flexible Semiconductor Service Manufacturing Base Project was grandly held in West Fengxi New City, West Xian Xin New District, Shaanxi province on the morning of October 16, with its theme being "Shinning Shaanxi and Shaping the Future World".

A number of Chinese government leaders, partners from home and abroad, as well as the media attended the event, where the duo direction foldable AMOLED display with internal and external folds developed by the R&D team was also displayed.

Tianma demonstrates its latest foldable, flexible and rigid AMOLEDs at SID 2018

Tianme had an large booth in SID, showcasing many display technologies and demonstrating its latest LCD and OLED panels. Tianma started producing rigid and flexible OLEDS in April 2017 at the company's 6-Gen fab in Wuhan, and at SID the company demonstrated its 5.5" on-cell rigid AMOLEDs now in production. Tianma told us that this display was adopted in smartphones by Lenovo and Asus.

Tianma also demonstrated several flexible OLEDs in many configurations which we will list below. Almost all of the panels were based on the same basic display - a flexible 5.99" WQHD 1440x2280 (537.5 PPI) AMOLED produced on a polyimide substrate. Tianma showed this panel in a regular design, and also in a notch-type design.

Guangzhou New Vision demonstrates its latest flexible and foldable OLEDs

China's Guangzhou New Vision demonstrated its latest flexible and foldable AMOLED displays at SID DisplayWeek. According to the company in the video below, these displays will enter production in 1.5 years.

As can be seen in the video, the company is developing flexible OLEDs with a resolution of 400 PPI on oxide-TFT backplanes and Polyimide substrates. New Vision also develops printing technologies (for both OLED and QLED displays, interestingly) - but these are still in an early stage, it seems.

Digitimes: Samsung and LG aim to reduce their reliance on foreign organic material producers

Digitimes Researcher states that currently Samsung Display and LG Display both rely on imported organic materials used in OLED production, but the two Korean makers aim to decrease this reliance. Both companies are buying stakes in companies outside of Korea (for example Samsung's Novaled acquisition and Sun Fine Chem investment) in order to obtain patents and move production in house, mostly at LG Chem and Samsung SDI.

The polyimide used as a substrate in flexible OLEDs, for example, is produced by Japanese Ube Industries - and used by both LG and samsung. Several organic materials used in the OLED stack are produced by Universal Display (PHOLED emitters), Idemitsu Kosan, Dow Chemical and Merck. Both companies use glass mostly from Corning and high-temperature thin film for the back-end processing from 3M.

Researchers at Tohoku University develop a super flexible liquid-crystal device

Researchers at Tohoku University in Japan developed a super flexible organic liquid crystal device, which they say are promising for next-generation highly-flexible LCD displays. The new device is formed from ultra-thin plastic (polyimide) substrates that are firmly bonded by polymer wall spacers.

The transparent polyimide substrate (made by Mitsui Chemicals) are about 10 um thick each, and feature heat resistance and the ability to form fine pixel structures, including transparent electrodes and color filters. The refractive index anisotropy is extremely small, making wide viewing angles and high contrast ratio possible.

Yole Developpement sees OTFT-based flexible OLEDs within 2-3 years

Yole Developpement released a new report covering the OTFT market for flexible displays and other applications. According to Yole, some display makers in Taiwan and China are currently in the process of industrializing OTFT-based displays - flexible LCDs at first, with flexible OLEDs coming within 2-3 years.

OTFT penetration for displays (2016-2022, Yole)

The mobility of OTFTs are already high enough for LCDs (higher than a-Si) - but still not enough for OLEDs. But in 2-3 years this should be resolved, with low-performance (200 PPI) OLED displays for wearables, some consumer applications and embedded automotive OLEDs possible within 2-3 years.

Screen Holdings starts making flexible OLED deposition equipment

Screen Holdings logoJapan's Screen Holdings (previously Dainippon Screen Mfg), a manufacturing equipment maker, announced that it started producing mass-production systems for OLED deposition - and began supplying these to display makers in April.

Screen Holdings is already making OLED deposition systems, but only R&D tools. The company finished the development of 6-Gen tools that can coat on polyimide substrate - for flexible OLED production.

Samsung to use a hybrid glass-polymer in its upcoming foldable OLEDs

According to reports, Samsung is gearing up to introduce their first foldable OLED smartphone device by the end of 2016, as Samsung's mobile phone unit is under pressure to innovate and recapture its lost market share.

According to an interesting report from Korea, Samsung has been collaborating with a KAIST spin-off called Solip Technology that developed a foldable glass that will be used in Samsung's upcoming foldable OLEDs. Samsung is considering placing a strategic investment in Solip as this material is a key technology for Samsung.

Guangzhou New Vision shows a new 0.01 mm thick flexible OLED prototype

China's Guangzhou New Vision has been developing flexible AMOLED displays for a long time, and the company now unveiled its latest prototype. This 0.01-thick panel use a Polyimide substrate, an Oxide-TFT backplane and an RGB (direct emission) frontplane. The curvature radius is 4.5 mm.

New Vision's 2014 flexible AMOLED prototype actually used a PEN substrate - and it's interesting to see the coming moving back to Polyimide. Back in 2014 New Vision said that the flexible OLEDs will be commercialized "in the near future".

Samsung shows new foldable OLED prototypes, world's largest transparent OLED

Samsung hosted an investors forum in NY a few days ago, and it is reported that much of Samsung's focus was on OLED technologies. As we already reported, Samsung Electronics announced that flexible OLED is one of its 3 areas of future growth (especially as they struggle to increase high-end mobile phone sales), and during the conference the company revealed some interesting information and prototypes.

Foldable OLED concept (2013)

So first up were two new foldable OLED prototypes - a 5.5" (WQXGA, 2048x1526, 464 PPI) panel that folds in half and a 10" tri-foldable AMOLED (Full-HD, 218 PPI).
