Rollable OLED displays are exciting - as these displays can enable new device form factors - such as TVs that roll up into a small cylinder or a tablet-sized device that can roll-up into a pen.

Rollable OLED TVs

In early 2019, LG launched the world's first rollable OLED device - a TV that rolls into its base. The 65" Signature OLED TV R has three viewing options - full view, line view and zero view. This is a radical new TV form factor which carries an extremely high price. Hopefully prices will be reduced as the technology matures.

Rollable mobile devices

While LG is leading the race to rollable OLED TVs, many display makers are developing smaller rollable OLED displays for mobile devices. Commercial adoption hasn't started yet, but it is likely that we will see the first rollable OLED smartphone in the market by the end of 2021 or early 2022.

The latest rollable OLED news:

BOE demonstrates new OLED displays at SID Displayweek 2022, including a 95" 8K OLED TV

BOE demonstrated its latest OLED technologies and displays at SID Displayweek 2022. The most interesting display is a 95-inch 8K HDR OLED display, produced on an Oxide-TFT panel with a white-OLED CF structure. The panel was produced using an evaporation method.

This is the first time we hear of BOE's evaporation TV program, since around 2016. The company has an active inkjet printing OLED TV project, and in December 2019 it unveiled a 55" 8K (160 PPI) printed OLED TV prototype.

Samsung shows its latest OLED displays at SID Displayweek 2022

Samsung Display unveils new OLED displays at SID Displayweek 2022. First up is the Flex G flexible display, which folds inwards twice, and the Flex S, that can fold both inwards and outwards.

Samsung is also new rollable displays - a 6.7" slidable display that can expand and a larger 12.4" slidable OLED that can expand from both ends. When close, the display is 8.1" in size.

Samsung aims to reduce the thickness of its future QD-OLED panels by removing the QD glass substrate

According to reports in Korean media, Samsung is developing a new process which will allow it to reduce the thickness of its QD-OLED panels.

The current QD-OLED design uses two glass substrates, one for the TFT backplen (and the OLED frontplane materials), and one for the QD conversion layer. The new plan is to remove the QD glass substrate, and inkjet print the QDs directly on the OLED TFE encapsulation layer.

LG Display announces the 20 semifinalists in the 2nd OLED Go! design competition

DSCC sees a $63 billion OLED market in 2026, driven by high demand for laptop, monitor and tablet displays

DSCC has released its latest OLED market forecast, and the company forecasts a 8% CAGR revenue growth, with the market reaching $64 billion in revenue in 2026. The growth will be fueled by high demand for laptop, monitor and tablet displays. The smartphone and OLED TV market will also continue to grow.

OLED market forecast, early 2022 (2021-2026, DSCC)

DSCC sees a 31% CAGR shipment growth for laptop displays, to reach around $2.4 billion in 2026, and a 95% CAGR unit growth for monitor OLED displays, which will reach $1.3 billion in 2026 (up from $200 million in 2022). This is fast growth for monitor OLED displays, but slower than DSCC previously estimated, due to competition for miniLEDs, rigid OLED capacity that will be used for laptops and tablets and lower demand to mirroring display monitors.

TCL shows a 14-inch inkjet-printed rollable OLED display

Yesterday we reported that during its DTC 2021 conference, TCL demonstrated a 65" inkjet-printed 8K OLED panel co-developed by TCL's CSoT and JOLED. During the conference, the company also unveiled another panel a rollable OLED.

This is a 14" inkjet printed OLED panel, produced using an inkjet printing process. TCL says that it has a rolling radius of <20 mm, and has been tested for up to 100,000 cycles. The panel include a built-in AI-powered compensation algorithm (we don't have more info on that). The display has been developed by CSoT in collaboration with JOLED.

Where are the rollable OLED smartphones?

In early 2021 we hoped that by the end of the year, we'll see some commercial rollable OLED smartphones. LG Electronics aimed to be the first company to release such a advice, hoping to launch it in early 2021.

Later in 2021 LG Electronics closed its smartphone business, and the rollable OLED phone project was scrapped. LG is still offering the rollable OLED TV, but this uses a completely different production process, and is extremely pricey (it is likely that LG only shipped a handful of these TVs to date).
