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:
As was reported two days ago, Samsung is showing a new AMOLED display at CES 2023, that is both foldable and rollable.
The so-called Flex Hybrid OLED opens up from 8-inch when closed, to 10.5" when opened - and 12.4" when fully rolled up.
According to a report from Korea, Samsung Display will unveil a new display at CES 2023, which is both foldable and slidable. The display is 8-inch in size when folded, opens up to a 10" display when unfolded, and then can be slided further to 12.4".
The display will be shown in a private booth, which will not be open to the public. It is likely that this display is still at an early stage of development, as there are many challenges such as durability and quality that Samsung will need to overcome. The report suggests, though, that Samsung is ready to soon commercialize such a panel.
During Lenovo's Tech World 2022 event, the company and its Motorola subsidiary showed new device prototypes, including two interesting rollable OLED devices.
In the video above, you can see a new laptop prototype that has a rollable OLED display, that opens up to increase the screen size. There's also a smartphone that opens from a 4-inch display to a 6.5-inch one using a rollable display.
During Intel's Innovation Day 2022, Samsung Display's CEO shows a prototype rollable AMOLED laptop display that opens up from 13-inch to 17-inch:
Over the years, Intel has been working with display makers to showcase innovative new display technologies. In early 2020 the company showed a foldable 17-inch laptop device.
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 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.
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, together with British design magazine Dezeen announced the semifinalists in the 2nd OLED Go! Design competition. LG says that there was high interest in this year's competition, with over 300 entries from all over the world, with many innovative ideas.
Many of the designs utilized future flexible, rollable and transparent OLEDs to create new innovative future products, for both residential and commercial applications.
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.
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.
Samsung Display showed new foldable and rollable OLED device prototypes at CES 2022, using the new Flex branding it launched in November 2021.
So first up with have the Flex Slidable, which is a smartphone type device that opens up to a wider display. The second display is the Flex S which is a foldable device that folds twice, once inwardly and once outwardly, in an "S" shape.
