LG Display detailed its latest automotive display strategy. The company is now offering three product family. For luxury flagship cars (over $80,000 in cost), the company is offering its P-OLED flexible panels, that offer high performance coupled with design freedom.

For premium cars ($50,000 - $80,000) the company offers rigid OLEDs, that offer high image quality and a tandem OLED architecture for increased efficiency and lifetime. These displays are lower in cost compared to LG's P-OLEDs, and LG brands these as ATO (Advanced Thin OLEDs) as they adopt TFE encapsulation over a glass substrate. For mass market cars ($30,000 - $50,000) LGD offers LTPS LCDs.

Samsung announced several new devices today, all utilizing AMOLED displays. We'll start with the two new foldable phones, the Galaxy Z Fold5 and Z Flip5.  The Fold5 offers a foldable 7.6" 120Hz 1812x2176 foldable AMOLED display, and a 6.2" 120Hz 904x2316 cover AMOLED. The phone has a Snapdragon 8 Gen 2 chipset, 12 GB of RAM, up to 1TB of storage and a triple camera setup.

Samsung's Galaxy Z Flip5 smartphone offers a foldable 6.7" 120Hz 1080x2640 foldable AMOLED display, and a small 3.4" 720x748 cover Super AMOLED display. The phone has a Snapdragon 8 Gen 2 chipset, 8 GB of RAM, up to 512GB of storage and a dual camera setup.

Three display makers in China (BOE, Tianma and Visionox) reported their preliminary financial results for the first half of 2023. It seems as if all companies are facing a sluggish economy and lower demand for displays - but the OLED business is actually seeing increased demand.

We'll start with BOE, that expects an operating profit of around 700-800 million Yuan ($97-110 million USD) in the first half of 2023, a decrease of around 90% from last year. BOE says that it is starting to see demand increasing as the year progresses.

China-based Visionox demonstrated many OLED displays and new technologies at Display Week 2023.

So first up, we have some rollable and foldable OLEDs. You can see some impressive looking such flexible OLEDs in the video above, and Visionox featured many such displays at their booth.

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.

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.

DSCC says that BOE's market share in the flexible (and foldable) smartphone OLED market has risen to 27% in Q1 2023. BOE flexible and foldable OLED panel sales grew 81% in Q1 2023 compared to last  year, as the company enjoys growing sales to Apple, Huawei, Oppo, Realme, Vivo and ZTE. BOE is mostly taking market share from Samsung and LG, while Tianma's market share is also on the rise.

DSCC estimates that flagship smartphone shipments grew 17% in the first quarter, with flexible OLED smartphone shipments growing 18% and foldable ones growing 4%.

Researchers at the University of Chicago, led by Sihong Wang (above) and Juan de Pablo, developed a stretchable OLED device that uses TADF emitters to enable high efficiency and high stretchability.

The researchers say that this is the highest-efficiency stretchable display demonstrated to date, as all previous designs used fluorescent OLED emitters. The TADF stretchable device achieves 10% EQE and a stretchability of 125%. The substrate of this new device is a newly synthesized polymer.
