TCL CSoT had several interesting new OLED demonstrations at SID DisplayWeek 2023, all of which were produced by inkjet printing, which shows the company's commitment to the new production process.

First up is the company latest inkjet-printed panel, this time CSoT showed a 8K (7680 × 4320) 65" TV panel that is foldable (with a bending radius of 25 mm). The panel offers a peak brightness of 800 nits, a response time of under 1 ms and a refresh rate of 120Hz.

During Display Week 2023, BOE showcased a 15" 2560x1600 rollable OLED display.

The display offered a rollable radius of 10 mm (outwards), and can roll 50 mm of its length, changing from the full 15" 16:9 display to a 13.6" 24:9. This is not as impressive as Samsung's rollable demo that grew 5 times its original rolled size.

During DisplayWeek 2023, BOE demonstrated a new OLED microdisplay. The panel is 1.3" in size, and it offers a 3552x3840 resolution (4031 PPI), a refresh rate of 90Hz, and a color gamut of 90% DCI-P3.

This is BOE's largest and highest-resolution OLED microdisplay to date. BOE's current OLED microdisplays, already in production, include a 0.39", 0.49" and 0.71" FHD panels (all of which are available on the OLED marketplace, by the way).

BOE has plans to construct an 8.5-Gen AMOLED production line with a capacity of 30,000 monthly substrates to produce IT displays for laptops, tablets and monitors. The company aims to build the B16 factory in Chengdu, Sichuan.

According to Korea's ETNews, BOE is facing delays with its B16 plans. The company is seeking support from the local government, but it has yet to gain support.

Taiwan-based AU Optronics (AUO) demonstrated several microLED display prototypes at Display Week 2023, showing the company's focus on microLED display technology as its next-gen platform.

Sample displays include a 13.5" Full-HD 5,000-nits 55% transparent display, a 17.3" transparent panel that includes an embedded LC layer so it turn from 55% transparency to an almost completely opaque display, a 14.5" 2560x1440 foldable laptop display that is based on blue microLEDs with QD color conversion, and more.

Samsung Display demonstrated many OLED technologies at Display Week 2023, which we'll detail below. It seems that the main new technology was the Sensor OLED Display, which is an OLED with an embedded sensor that can perform fingerprint sensing in addition to blood pressure, heart rate sensing and stress level sensing (all from reading the finger), which the company says is the first such display in the world.

The Sensor OLED Display embeds light-sensing organic photodiodes (OPDs) inside the display itself, which allows it to perform the sensing functions all over the display. Samsung explains that as OLED light is reflected differently depending on the contraction and relaxation of the blood vessels inside the finger, the OPD senses the light when it returns to the panel, and converts it into health information.

Display Week 2023, the industry's premier event, is now over, and it was a great week. We had dozens of meetings and saw many next-generation display technologies. As we go over all materials, we will upload new stories to detail the displays on show.

In the meantime, here are our key takeaways from this show:

Universal Display announced that it will detail advances in its latest PHOLED materials at Display Week 2023. The company's latest red, green, and blue PHOLED materials offer a narrow emission spectrum, which increases the efficiency of OLED devices, in addition to enhancing the color gamut.

UDC also unveil a new OVJP system printed on a 200mm x 500mm Corning Astra Glass substrate. UDC will also showcase the first-ever fully printed seven-layer (HIL/HTL/EBL/EML/HBL/ETL/EIL), 80 PPI, green commercial-level PHOLED device fabricated by its R&D OVJP system that has comparable device performance with vacuum thermal evaporation (VTE).

UK-based Excyton is happy to announce that it will showcase its novel TurboLED OLED architecture and technology at the 2023 Displayweek event (May 23-25, Los Angeles, California). Excyton has been accepted to participate at the 2023 I-Zone event.

TurboLED is a game-changing technology that offers a dramatic boost to the performance of displays. In a TurboLED OLED display, each pixel comprises deeper and lighter color red, green and blue emitters to maximize performance - in fact Excyton has shown that the TurboLED architecture leads to a 50% reduction in power consumption, a 3X improvement in emitter lifetime and an increased color gamut. TurboLED displays are especially suited for demanding applications, such as IT displays, automotive displays, gaming monitors, AR/VR headsets, smartphones and wearables.

In 2000 PPG Industries and Universal Display established a strategic relationship in 2000, and since then PPG has been the exclusive producer of UDC's PHOLED emitter materials. In 2021, the two companies announced that they will establish a new manufacturing site in Shannon, Ireland, for the production of UDC's emitters. Now UDC announced that the new fab is commencing operation.

The new production site will double PPG's production capacity of UDC's PHOLED emitters. This will also increase the company's ability to ensure uninterrupted supply of its crucial materials for the OLED industry.
