LG reportedly sold only 10 rollable OLED TVs in Korea since October 2020

In October 2020 LG Electronics started shipping the world's first rollable OLED TV, the 65" 65RX OLED TV. The price is set at KRW 100 million (USD 87,000). That price was actually cheaper than expected - but according to a report from Korea LGE managed to sell only 10 such TVs.

According to the report, it's not just the high price that is keeping consumers away - the TV, which is based on rollable glass, is not very durable.

Samsung Electronics halts its foldable UTG glass project

Samsung Electronics started to adopt ultra-thin glass covers for its foldable AMOLEDs, instead of polyimide, as it says UTG offers higher durability. Samsung currently uses Samsung Display's UTG, and according to reports it aimed to develop its own solution in collaboration with Corning

A new report from Korea suggests that Samsung Electronics has halted this project as it realized it should better increase the efficiency of its current supply chain (i.e. Samsung Display's UTG solution) and secure lower prices. It may be that this decision is only temporarily, as it is likely that Samsung Electronics is still aiming to also increase the durability of its UTG covers and not just decrease costs.

ETNEws: Apple aims to start using OLED displays in iPad devices in 2022

Last month we posted that the Korean Elec publication claims that Apple is aiming to adopt OLEDs in its next iPad Pro devices - and as Apple wants extended lifetime from these panels, the Korean panel makers are developing tandem OLED devices (easier for LG as it is already producing such panels for automotive applications).

Today another Korean publication, ETNews, has posted that Apple is aiming to start using OLEDs in its iPads in 2022. According to ETNews, Apple indeed reached out to both LG Display and Samsung Display for these OLEDs.

Online review shows that the Galaxy Z Fold 2 is more durable than the original Fold, but not by much

When Samsung launched its original foldable smartphone, it used a polyimide-based cover, and the screen was fragile and not very durable. Later in 2020 Samsung Display launched its ultra-thin-glass (UTG) cover (produced by Schott and processed by Dowoo Insys) which the company said is more durable the the Polyimide.

Samsung Electronics continued to adopt the new foldable UTG cover and used it in its Samsung's Galaxy Z Fold2 5G (7.6" 1768x2208 HDR10+ 120Hz Dynamic AMOLED) smartphone. But the question remains - just how more durable is the UTG-protected OLED?

Samsung Display announces a 1.4R foldable OLED display

Samsung Display announced that it has commercialized a new foldable OLED display that is the first to achieve a curvature radius of 1.4R mm. This display will be adopted in Samsung's Galaxy Z Fold2 5G (7.6" 1768x2208 HDR10+ 120Hz Dynamic AMOLED) with an Ultra-Thin Glass (UTG) cover glass.

Samsung says that in order to minimize the folding stress that is increased in such a small folding radius, the company has optimized a series of technologies related to the material of the display, the panel design and the module assembly, so that the multi-layered structure will function like a cushion when the panel is folded.

Samsung Electronics collaborates with Corning on Ultra Thin Glass technology for foldable OLEDs

Samsung started to adopt ultra-thin glass covers for its foldable AMOLEDs, instead of polyimide, as it says UTG offers higher durability. In the Galaxy Z Flip, Samsung used a UTG cover produced by Korea-based Dowoo Insys, who processes Schott's ultra thin glass for Samsung Display.

In April 2020 it was reported that Samsung Electronics wants to develop its own UTG cover technology, as as it feels that Samsung Display's UTG is still not robust enough and the company also wants to increase production yields and reduce costs. Now there are new reports from Korea that say that Samsung Electronics is collaborating with Corning in this new UTG project.

UBI sees fast growth in Polyimide films and ultra-thin glass for foldable smartphone displays

UBI Research estimates that foldable smartphone display makers will continue to rely on both Ultra-Thin-Glass (UTG) and Colorless Polyimide (CPI) films for at least the next five years.

Foldable UTG and CPI market forecast (2020-2024, UBI)

UBI sees demand for CPI films will reach 4.3 million units in 2020 while demand for UTG will reach 3.5 million units. Demand for both products will grow and by 2024 it will reach 37.1 million units for CPI and 30.5 million for UTG.

Omdia sees 73 million foldable AMOLEDs displays shipped in 2025

Omdia says that the global foldable OLED display market will grow from 700,000 units to 3.9 million in 2020 (a 5X increase) - and will continue its fast growth to reach 73.1 million in 2025.

Omdia says that the main challenge of the foldable OLED market is the reliability of the displays - mainly the cover, the touch sensor and the polarizer films. Display makers will need to adopt new technologies such as ultrathin glass covers (UTG), touch sensors on TFE and color filters on TFE

Samsung Electronics is looking to develop its own ulta-thin glass cover for foldable smartphones

Samsung Electronics's 2nd foldable smartphone, the Galaxy Z Flip, sports an ultra-thin glass cover, which replaced the polyimide one used in its previous foldable, the Galaxy Fold. The UTG glass cover is produced by Korea-based Dowoo Insys, who processes Schott's ultra thin glass.

According to a new report from Korea, Samsung Electronics wants to develop its own UTG cover, as it feels the Dowoo Insys UTG is still not robust enough and the company also wants to increase production yields and reduce costs. SE is already in talks with several glass suppliers for this project.
