On Seeya's OLED microdisplays status and plans

OLED microdisplay developer Seeya Information Technology was established in 2016, and in 2017 it started building a $300 million OLED 300 mm microdisplay production line. Seeya's fab is now in operation, with a yearly capacity of around 20 million displays (monthly capacity of 9,000 300 mm wafers).

Seeya quickly became a prominent display maker, who's currently producing high performance displays to global customers. The company says it's currently the world's largest OLED microdisplay maker by volume. Seeya's current standard displays include:

Will Samsung Electronics start using LGD's OLED TV panels?

According to an interesting report from Korea, Samsung Electronics is discussing a potential supply agreement with LG Display for WOLED TV panels. Samsung is aiming, according to the report, to buy 1 million OLED TV panels in 2021, and 4 million (around 50% of LGD's capacity!) in 2022.

This development, if true, may have a major impact on the industry, and may spur LGD (and other OLED makers) to accelerate OLED TV production and capacity expansion plans.

LGD's Guangzhou OLED TV fab suffers from low yield, mass production not achieved yet

On August 30 LG Display announced today that it started producing OLED TV panels at its 8.5-Gen OLED fab in Guangzhou, China. LGD hoped that mass production will begin shortly, but according to a new report from Korea the new fab's yields are low (50-60%) and actual mass production has not started yet.

LGD's new fab has a monthly capacity of 60,000 substrates, which will be expanded to 90,000 by 2021. The company has now lowered its OLED TV forecasts for 2019 as it did not meet its goal of starting shipping commercial panels in October.

IHS: Ink-Jet printing to finally become a mass production OLED production process in 2020

IHS says that ink-jet printing of OLED displays is finally ready to enter mass production in 2020. Production will begin at a rate of around 105,000 yearly substrates (209,000 sqm) in 2020, but will grow 12-fold within 4 years to reach 1.3 million yearly substrates in 2024 (or 7.3 million sqm).

The first producer to begin mass production using ink-jet printing will be JOLED who will enter mass production in 2020 (it already produces panels but at very low volume). OLED makers in China will quickly follow JOLED with mass production investments starting in 2020 or 2021.

SEL shows a 8.3" 8K OLED with 1058 PPI, and a new foldable OLED prototype

Semiconductor Energy Laboratory (SEL) demonstrated two new OLED display prototypes, both based on the company's proprietary CAAC-IGZO (c-axis aligned crystalline In-Ga-Zn-O) backplane material.

First up is the world's smallest 8K display, a 8.3" OLED (1058 PPI) with a resolution of 7680x4320. The panel is based on a white OLED with color filter architecture.

DSCC: Samsung to begin pilot QD-OLED production in 2019

DSCC estimates that Samsung will begin pilot production of QD-OLEDs in 2019, with a capacity of 5,000 monthly 8.5-Gen substrates. If this is successful, Samsung will double the capacity in 2020 and add a further 30,000 yearly substrates in 2021 and again in 2022. Material revenues for Samsung's QD-OLED TVs will reach $56 million in 2022.

DSCC admits, though, that as Samsung faces several technical challenges before it could launch commercial QD-OLED TVs, its forecast could be way off - there's a good chance that SDC will cancel the project, or it could increase capacity at a much faster rate than DSCC estimates and even scale-up production to 10.5-Gen.

Google and LGD developed a 1443 PPI 4.3" 120Hz VR AMOLED display

In May 2017, Google announced that it has partnered with "one of the leading OLED makers" to develop a high-end VR display. Google is now set to demonstrate this display at SID 2018 in May.

The new Google-designed display is a 4.3" 18Mp (1443 PPI, probably around 5500x3000 resolution) VR display featuring a refresh rate of 120 Hz. This will be the highest-density OLED display ever (not counting OLED-on-silicon microdisplays). Current VR AMOLEDs in production reach only about 600 PPI.

ETNews: Samsung is developing hybrid QD-OLED TVs

ETNews posted an interesting article, claiming that Samsung Display is developing a new TV technology that combines OLED emitters with quantum-dot photo-luminescence materials. The basic idea is to use blue OLED emitters and then convert the blue light to white light using quantum-dots combined with color filters (QDCFs) to add red and green colors.

This seems to be a rather complicated design, but it could be much easier to produce compared to a true RGB OLED TV, as there is no need for precise OLED patterning. This is similar to LG's WRGB OLED TVs which use a white OLED source (made from yellow and blue emitters) and color filters on top.

DSCC: Ink-Jet printing could lead to 17% cost reduction in 55" OLED TV production

LG Display currently produces all its OLED TV panels using an evaporation (VTE) process. Market research company DSCC says that ink-jet printing is more efficient than current VTE processes as it will result in simpler displays (no need for color filters, for example, as used by LG's current WRGB displays). Ink-Jet printing will also enjoy lower depreciation costs and lower indirect expenses such as water and electricity.

DSCC estimates that an ink-jet printed 55" OLED TV panel will cost 17% less to produce compared to a VTE produced panel. An ink-jet printed panel will theoretically be significantly brighter (as the color filters absorb a large portion of the light), however solution-based OLED materials have traditionally lagged behind evaporation ones (Merck though says that the latest soluble materials are on-par with evaporation ones).

IHS: AMOLED production capacity set to grow over 300% in the next 5 years

IHS Markit says that global AMOLED production capacity is set to grow from 11.9 million square meters to 50.1 million sqm in 2022 - that's a 320% growth in 5 years. Samsung and LGD will remain the market leaders and Korea will have a market share of 71% in 2022 (down from 93% in 2017). China-based OLED makers will have a market share of 26% in 2022 (up from 5% in 2017).

AMOLED production capacity (WOLED vs RGB, 2012-2022, IHS)

IHS says that the majority of OLED capacity will still be used to produce RGB (direct-emission) OLEDs in 2022. RGB OLED production capacity will grow from 8.9 million sqm in 2017 to 31.9 million sqm in 2022. WOLED (WRGB) OLED TV panel capacity will grow from 3 million sqm in 2017 to 18.2 million sqm in 2022.
