4K OLED

TCL CSOT demonstrated its latest displays, technologies and prototypes at Display Week 2024. The company is focused on inkjet printing technologies, and a lot of the displays on show were indeed printed.

So first up, we TCL demonstrated a 14" 2880x1800 400 nits 30-120Hz ink-jet printed LTPO AMOLED display. The display is produced on a glass substrate, with thin film encapsulation (a 'hybrid OLED').

LG Display announced that it has developed world's first OLED gaming monitor panel with a switchable refresh rate and resolution. The company already mass producing this panel and will now aim to accelerate its market adoption and expects the first product to use this panel to arrive soon from LG Electronics, and other global gaming brands.

The new panel is 31.5" in size, and allows users to choose between two modes - high refresh rate more (480Hz and FHD) and high resolution mode (4K, 240Hz). The high refresh mode is aimed towards games in which speed is particularly important, such as first-person shooter (FPS) or racing games. The higher-resolution mode is more suitable for watching movies or 4K content. 

Panasonic Avionics announced that it shipped its first batch of the latest Astrova 4K OLED inflight entertainment monitors. These monitors will be installed on Icelandair's forthcoming new fleet of leased Airbus A321neo LR aircraft (due in Q4 2024).

Icelandair will install 16" panels in its business class seats and 13" panels in economy. The new Astrova 4K OLED monitors offer HDR10+, high-fidelity multi-channel audio, USC-C 100W fast charging ports, and an external processing unit that can be placed in the seat box for easier installation.

Samsung Display announced that it is beginning to produce a new 31.5" 4K QD-OLED. This is SDC's highest density QD-OLED display, at 140 PPI. The company recently upgraded its QD inkjet printing deposition system to support this higher resolution. It will also enable SDC to produce 8K 65" QD-OLED displays (that will also be 140 PPI). 

Samsung Display also announced that next year it will start producing 27" QHD QD-OLED monitor panels that will support a 360Hz refresh rate, targeting the gaming monitor market. 

Apple first VR headset, the Apple Vision Pro, adopts dual 1.3" 4K OLED microdisplays made by Sony. According to reports, Apple is looking to replace Sony as its supplier and is testing displays made by Seeya and BOE. Apple seems to be aiming to adopt these in its next-gen Vision Pro model - and also in a future low-cost mixed-reality headset.

Sony officially launched its 1.3" 4K OLED displays last week, with an official price of $1,000 per unit. Some reports suggest that Apple is paying $350 per display - which is still very expensive, as the two OLED displays cost almost half of the total production cost of the Vision Pro (estimated at $1,500).

Back in 2021, Sony unveiled a 4K OLED microdisplay prototype. In June Apple announced the Vision Pro headset, which uses two Sony-made 1.3" 4K (3,552 × 3,840) OLED microdisplay, made by Sony. And today Sony finally officially introduced its ECX344A display, targeting VR and AR devices.

Sony says that in order to develop the new display it developed new miniaturization processes as well as a new pixel drive circuits and a high-speed driver circuit. Sony says that the display will ship by the end of 2023 and its price is set at 150,000 Yen, or just over $1,000 USD (it is estimated that Apple pays around $350 for each panel).

United Airlines has ordered Panasonic Avionics' Astrova aircraft internal entertainment platform to be installed at United's new Airbus A321XLR and Boeing 787, starting in 2025. 

Panasonic's Astrova platform is based on 4K OLED displays. United did not specify which OLED sizes will be used, but we know that Panasonic offers 13-, 16- and 22-inch options for regular (economy) passenger seats (while it offers 19-, 22-, 27-, 32- and 42-inch for business-class seats, these displays were just announced a few days ago).

In 2022 Panasonic Avionics launched its Astrova aircraft internal entertainment platform that is based on 13-, 16- and 22-inch 4K OLED screens. The company is now adding larger OLED screens to the Astrova lineup.

The new OLED displays, aimed for business-class and first-class cabins, will be available in five sizes 19, 22, 27, 32, and 42 inches. Beyond the increased performance, Astova also offers significant weight savings compared to other seat-end architectures.
