Researchers from Japan's Chiba University developed a new method to deposit thin OLED layers that achieves controllable molecular arrangement - that can be used to increase the efficiency and lifetime of OLED devices.

The method, called intermittent deposition, uses pauses in deposition and changes in deposition conditions to invert the orientation of the organic molecules, thus achieving high control over the resulting films. The researchers built on a tool called Rotary Kelvin Probe (RKP) that is used to measure the surface potential during and after the deposition in real-time. The new approach of intermittent deposition created a relaxed and stable surface layer with controllable polarization. 

Reports from Korea suggest that Samsung Display and LG Display are starting to produce AMOLED displays for Apple's future iPads, to be announced later this year. Samsung is set to produce 11" LTPO AMOLED displays, while LG Display is producing displays for the 13" model (but LGD will also produce 11" AMOLEDs in the future for Apple). 

The Elec says that both Korean makers developer 11" and 13" displays, but for some unknown reason only LGD will produce the 13" displays. This could change in the future, of course. One reason could be that LG Display has more experience with tandem OLED architectures (developed originally by LGD years ago for automotive OLEDs).

TCL is demonstrating a new 14" 4K 120Hz flexible AMOLED display that adopts a tandem display structure. The tandem structures enabled a reduction in power consumption of over 30%, an extension of the display's lifetime (3.5X) and a peak brightness of over 2,500 nites.

TCL was also showing a new 6.36" 1200x2670 LTPO AMOLED display, that features the company's new frequency division technology and self-developed frequency scanning circuits. Coupled with an ultra-low power consumption IC, it offers 15-20% power savings compared to TCL's standard AMOLEDs. 

During CES 2024, many device makers announced new laptops, monitors and TVs that use OLED displays. Here's a list of all these new devices:

• MSI Monarch 13 laptop (13.3" 2.8K AMOLED)
• LG OLED B4, C4, G4, M4 (WOLED TVs)
• Samsung Odyssey G9 monitor (49" 5120x1440 240Hz QD-OLED)
• Samsung Odyssey G8 / G6 monitors (27" 1440p 360Hz / 32" 4K 240Hz QD-OLED)
• Razer Blade 16 2024 laptop (16" 2560x1600 240Hz SDC AMOLED)
• Dell 2024 XPS 13 / 14 / 16 laptops (16" 90Hz 4K / 14.5" 120Hz 3200x2000 / 13.4" 2880x1800 60Hz AMOLED)
• Acer Predator X34 X / X39 monitors (4" / 39" 3440x1440 240Hz OLED)
• LG Signature OLED T (77" 4K wireless transparent WOLED TV)
• Samsung S95D, S90D, S85D (QD-OLED and WOLED TVs)
• Gigabyte AORUS 2024 QD-OLED monitors (27", 31.5", 34" QD-OLEDs)
• Acer 2024 Swift 14 X / Swift Go 14 / Swift Go 16 laptops (14" / 16" AMOLEDs)
• Panasonic Z93A, Z95A (WOLED TVs)
• HP Omen Transcend 32 gaming monitor (32" 240Hz 4K QD-OLED)
• Dell Alienware AW2725DF / AW3225QF monitors (27", 32" QD-OLEDs)
• HP 2024 Spectre x360 14 laptop (14" AMOLED)

BOE demonstrated a new rollable AMOLED display at CES 2024, a dual-slidable display, that opens up on both sides.

When closed, the display is 13.6" in size, and when fully opened, it is 16.8". BOE did not disclose any more details.

BOE has been planning a 8.5-Gen flexible IT AMOLED Line for a couple of years, and in November 2023, following some delays, the company officially announced its plans for the new fab. Now we hear from China that the Chengdu local government, together with Chengdu's Hi-Tech Industrial Development Zone, have signed the contact with BOE to build the new plant.

The total investment in the fab is expected to reach 63 billion Yuan (over $8.7 billion USD). The fab will have a capacity of 32,000 monthly substrates (2290x2620 mm), and is expected to begin production by Q4 2026 (total construction time will be 34 months, according to the plan).

TCL CSoT demonstrated several OLED displays at CES 2024. first up we have an automotive 10.1” transparent OLED display, that offers 52% transparency. CSoT says that this is a "Smart Transparent" display, although it's not clear what is meant by that exactly.

The second display is a 14" 2.8K (2880x1800, 240 PPI) inkjet printed hybrid OLED. This is the first time that CSoT has printed a laptop AMOLED display. It uses an IGZO (Oxide-TFT) backplane, and offer a variable refresh rate (30-120Hz) to expand the battery life. This display was first shown last month, when TCL stated it is on track to start mass producing OLEDs using an inkjet printing process in the second half of 2024.

Samsung Electronics announced its 2024 OLED TV lineup, with 3 series. The company's flagship OLED TV for 2024, the S95D, offers 55-, 65-, or 77-inch 4K 144hz QD-OLED panels, offering high brightness (up to 3000 nits peak brightness), a new anti-glare coating to minimize reflections, Tizen 8.0 OS, and an external One Connect box for a sleek design. The S95D offers AI-Enhanced color accuracy - validated by Pantone.

Samsung also announced two more series - S90D and S85D. Interestingly, it did not detail whether these TVs use QD-OLED (produced by SDC) or WOLED panels (produced by LGD) - or a mix as it did last year within the same series. 

Samsung Display is showing its latest rollable automotive OLED panel, at CES 2024. The company says that this display, still at a prototype-stage, incorporates new technologies that enables it to be 30% thinner compared to SDC's previous rollable OLEDs.

Samsung is showing a wide of automotive OLEDs, including a display that is both rollable and foldable, check out the video above. There's also the round 9.4-inch AMOLED that will be used in the upcoming 2025 Mini Cooper.
