China's largest OLED substrate glass production line to reach mass production in August 2023

China's largest OLED substrate (carrier) glass production fab has initiated production, with full production is expected by August this year.

This is the first phase of the production hub planned at the Weifang Optoelectronics Display Materials Industrial Park, in Shandong province. Total investment in this line was 1.4 billion yuan (around $200 million USD), and the construction of the 2nd phase in this project has now started as well. The total investment in the four planned production lines will reach around $720 million USD.

LG Display and Samsung Display are both working on special glass-TFE OLEDs for Apple's future iPads

Apple's interest in OLED displays for future iPad tablet device is not secret, and many analysts estimate that the first such device will be released in 2024.

One of Apple's requirement is for superior performance for its tablets compared to smartphone AMOLED displays - and so developers are relying on a tandem OLED structure. According to a new report from Korea, LG Display is developing another unique technology for Apple's iPads.

OLEDWorks shows new flexible and rigid automotive OLED lighting solutions

Last week at CES, OLEDWorks demonstrated some of its latest automotive OLED Lighting solutions. Developed together with Corning, Valeo and STMicroelectronics, OLEDWorks’ newest demonstrator contained the highest density of individually addressable segments of any flexible OLED panel.

You can see the new flexible OLED demonstrator in the video above on the left (the device on the right uses rigid OLED panels). OLEDWorks says that individually segmented OLED lighting panels increase safety on the road by allowing for improved communication through dynamic animation sequences and symbols. Manufacturing these OLED panels on flexible glass further expands lighting design opportunities with the ability to conform with curved surfaces in the car, integrating lighting directly into the vehicle’s architecture.

Future-Prove Your Display Production - Laser Solutions for Flat Panel Displays

This is a sponsored post by Coherent

Lasers are utilized for numerous processes in flexible OLED production, just as they are in the manufacture of other display technologies. In fact, it can be reasonably claimed that lasers are a key enabling technology in the fabrication of modern, flat panel displays. And it’s likely that they will continue to perform essential fabrication steps as flexible and foldable displays become more commonplace.

There is a variety of processes within the flexible display production line where lasers have an essential contribution to enable high throughput, high yield mass production. Nowadays, the complexity of the displays is getting larger and the number and tasks of lasers within flexible OLED production is increasing.

For this reason, choosing the right laser really means choosing the right laser supplier. Manufacturers need a partner who has the specific technical and applications development resources to identify the best and most cost-effective solution. Coherent is that partner

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.

DSCC: miniLED IT panels are more expensive to produce than tandem OLED panels

DSCC posted an interesting article, comparing the production costs of OLED vs mini-LED panels for IT. DSCC estimates that for tablets and notebooks, a tandem structure will be used, and the panels will be based on rigid substrates.

Mini-LED vs OLED IT panel production cost comparison (2021-2025, DSCC)

In the chart above you see a production cost comparison, between 2021 and 2025, for 12.9" panels. DSCC looks at two OLED production options: a tandem OLED panel with an LTPO backplane produced in a 6-Gen fab, and a similar panel that uses an Oxide-TFT backplane and produced in a larger 8.5-Gen fab. As you can see, OLED panels are more cost effective, and will remain so throughout the forecast period.
