Rollable OLEDs: introduction and market status - Page 4

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.

LG Electronics officially launched its 2022 OLED TV range. The company will offer OLED TVs from 42-inch (which can also be used as high-end gaming monitors) to 97-inch ones.

LG's entry-level 2022 OLED TVs include the 60Hz OLED A2 and the 120Hz OLED B2. These TVs use LG's older-generation video processor and will range in size from 48-inch to 77-inch.

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.

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).

AU Optronics demonstrated two new OLED display prototypes at SID Displayweek 2021. The first display is a 4K 32-inch 144Hz inkjet-printed AMOLED panel.

The second display is a 5.6" rollable dual-sided AMOLED display - which shows images on both side of the display.

BOE demonstrates several new OLED technologies at SID Displayweek 2021. First up is a new rollable display. The new display is 8-inch in size, and it features a resolution of 2592x2176 and a bending radius of 4 mm. BOE says the new display passed over 200,000 sliding cycles.

Last year at Displayweek 2020, BOE demonstrated a 12-inch rollable OLED. It has since been working with LG Electronics on the company's rollable smartphone (which was since canceled as LG withdrew from the smartphone market) and with OPPO on a 7.4-inch sliding OLED phone.

In March 2021 Tianma unveiled a new OLED display technology, which it refers to as CFOT OLED - a polarizer-free OLED that adopts color-filters instead to remove reflections. The company demonstrated a 8.03" CFOT OLED prototype at SID Displayweek 2021:

Tianma says that a CFOT OLED enables a thinner design, improves the light emittance and also cuts the power consumption by 20%. The 8.03" display offers a resolution of 2000x2544 (403 PPI).

Chinese OLED producer Visionox demonstrates several new OLED technologies at SID Displayweek 2021. We'll list some of these new achievements in this post, and you can see these in the video below.

Visionox shows a 'dynamic' 12.3-inch rollable display which feature a 5 mm rolling radius. A 7.92" foldable (2 mm radius) wrap-around display solution. Visionox also demonstrates a 12.3" three-folded OLED that can fold inwards (2.5 mm radius) or outwards (6.5 mm) - to become a 5.4-inch display.

Samsung Display is unveiling new OLED technologies today at SID Displayweek 2021. The video below shows all the new displays:

First up we have a tri-foldable AMOLED display shown with a smartphone prototype. The display can be folded twice inside and outside, and when fully open the display is 7.2-inch in size.

Chinese smartphone producer TCL unveiled an interesting new smartphone prototype (concept?) called the Fold ‘n’ Roll.

As you can see in the video, the device has a 6.87-inch OLED display when fully folded. It can open up (out-folding) into a 8.85-inch display, and then it can open even further to a 10-inch tablet-like device using a rolling mechanism. The display itself is produced by TCL's CSoT subsidiary.
