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.

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.

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).

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.

A couple of weeks ago, at IDW 2016, AU Optronics introduced a new bi-directional foldable AMOLED display. This display can be bent both inwards and upwards, unlike previous foldable AMOLED prototypes which can only be bent in one direction.

AUO says that the AMOLED structure limits the flexibility, and to overcome this the company replaced the circular polarizer usually used with a thin (10um) color filter array (apparently this is an WRGB display). AUO also used specially-located TFT and TFE (encapsulation) layers that endure many folding cycles - AUO says that the display can be bent more than 1.2 million times in 4mm curvature radius. The entire display thickness is 100 um.
