Coherent launches a new 150 W infrared industrial femtosecond laser for large OLED display glass cutting

Coherent has launched a new Monaco infrared industrial femtosecond laser configuration with 150 W of output power. The company says that the new laser is ideal for cutting of large OLED display glass.

The OLED industry is now entering the IT display market (tablets, laptops and monitors) and this accelerates the demand for laser tools with higher output power that can process larger glass sheets than those currently used in smartphones and wearables. Coherent says that the new Monaco 1035-150-150 outputs more than double the power and pulse energy of existing configurations, enabling high-precision cutting of large glass panels in very high volumes to produce large OLED screens with perfect assembly fit in next-generation IT devices. Coherent says that its new laser is the smallest femtosecond laser of its kind on the market and the easiest to integrate into laser tools.

Samsung to prioritize its half-cut 8.5-Gen IT project with Canon Tokki as it hopes to supply OLEDs for Apple's future iPads

In the past year or so, much have been said about Samsung's plans to build a 8-Gen OLED IT production line, as the company wants to expand its capacity for monitors, laptops and tablet OLED displays.

Samsung plan for a full-cut 8-Gen line

As this is the first such production line, SDC had two ongoing R&D projects: one with Ulvac, that used full-cut vertical OLED deposition, and another with Canon Tokki, that used half-cut horizontal deposition. According to the latest reports from Korea, SDC decided to prioritize the Canon Tokki half-cut project, as the technology is more mature and is more likely to finish as per Apple's roadmap.

APS manages to produce a 3000 PPI direct-emission OLED using its latest FMM technology

In 2021 The Korean government launched a new project that aims to develop technologies for the production of OLED microdisplays for AR applications. The project is led by AP Systems (APS Holdings), and aims to produce a direct emission OLED microdisplay with a resolution of 4,000 PPI by 2024. Earlier this year APS developed FMM masks that reached 1,000 PPI.

APS now announced that it has produced a 3,000 PPI direct-emission OLED microdisplay, based on its FMM technology. This is very impressive progress.

Samsung starts building its first OLED microdisplay production line

Earlier in 2022, Samsung Display confirmed it is developing OLED microdisplays. Samsung admitted it is still at an early stage of development, and it said it will start building its first line (with likely limited capacity) in 2023. By 2024 it will mass produce displays, and in 2025 it will expand capacity so that by 2026 it will achieve full commercialization.

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

AP Systems developed an inkjet printing system for OLED OCR deposition

Korea-based OLED equipment maker AP Systems (APS) announced that it developed a new system to deposit optically transparent resin (OCR) using an inkjet printing process.

Current OLED production uses an adhesive tape (OCA) to connect the cover glass to the display. But OCA is time-consuming and relatively expensive. OCR, on the other hand, is deposited directly on the panel and is more cost effective. We recently reported that Samsung Display aims to adopt OCR technology in its foldable OLEDs to reduce costs, and is testing inkjet systems made by STI.

Technical challenges and price wars delay the industry's 8.5-Gen OLED IT displays production lines

Following strong demand for IT devices, and Samsung's success in the OLED laptop market, OLED makers have began to plan building new OLED production lines specifically for IT applications: laptops, tablets and monitors.

Several OLED makers, including Samsung, LG and BOE, are considering building 8.5-Gen production lines for this market. In fact DSCC estimated that there are 11 such lines under development right now. But it turns out that this is not so simple as designing the evaporation equipment for larger substrates is a challenge.

Kateeva did not yet receive any QD-OLED inkjet printers orders from SDC, and may lose its patent portfolio to its latest investor

In 2020 Kateeva lost Samsung's QD-OLED inkjet printing inkjet printing contact to Korea's Semes, which resulted in massive layoffs including some of Kateeva's executives.
