Researchers at the University of St Andrews and the University of Cologne developed a polariton-based OLED device that offers angle-independent narrowband emission.

Polariton-Exciton quasiparticles are created when an OLED material is inserted into a high-quality microcavity. The researchers explain that by sandwiching the OLED device between two "mirrors", strong coupling and hybridization of light and matter can occur. This leads to the creation of the polariton particles. 

Samsung Display started producing laptop OLED displays a while back, and now we are happy to offer one of these panels at the OLED Marketplace.

The display is a 15.6" 4K (3840x2160) laptop AMOLED, with an LVD interface. It is possible to add a touch layer.

Researchers from Korea's Pusan National University have developed a new low-cost hole injection layer (HIL) material for solution-processed OLEDs, achieving higher efficiency and lifetime compared to the current state-of-the-art.

The new material is solvent-resistant (>99%) and thermally cross-linkable. The researchers used this material to create a solution-procssed red phosphorescent OLED device. The researchers placed the material between the ITO electrode and the HTL material, thus achieving photo-crosslinking of (poly-TPD) as HTL on top of crosslinked HIL. 

OLED microdisplay maker eMagin reported its financial results for Q4 2022, with another strong quarter. The company's revenues reached $8.4 million, up 17% from last year. This is the fifth consecutive quarter in which eMagin achieved year-over-year revenue growth. At the end of the quarter, eMagin had $4.3 million in cash and equivalents.

For the full year 2022, eMagin reported revenues of $30.5 million (up 17% from 2021) and an income (EBITDA) of $2.2 million. 

DSSC says that more smartphone makers will join the foldable phone market in 2023, with 37 new models introduced (up from 19 in 2022) - including new models from Google and OnePlus. DSSC says at least 16 new clamshell phones will be released, at least 20 in-folding type and one new out-folding device.

Looking at foldable smartphone shipments, DSSC says that the market will grow 45% to reach 18.6 million units, as performance increases and price decreases.

According to reports from Korea, BOE is developing smartphone OLED displays  for Apple's iPhone 15 range, but it is facing technical hurdles.

Specifically, the iPhone 15 design has a camera (and FaceID sensors) punch-hole inside the OLED, and BOE's panel suffer from light leakage from the OLED into the camera hole area.

Wisechip has unveiled a new miniature near-eye display module that is based on a small PMOLED display. The company says that this cost-effective solution offers high-contrast and low-power, and can be used for rapid development and applications that only require a simple information display.

The display module combines a 0.19" monochrome (white) PMOLED display, and a small optical system. Wisechip says that the whole module can work up to 20 hours powered by a 70mAh lithium battery.

Buick announced a new electric vehicle in China, the Electra E5, based on General Motors' Ultium architecture. The new crossover offers a curved 30" 6K OLED display.

Buick did not release a lot of information on the new car, and we do not know whether it will be available in China only, or will also be released globally. The car will start shipping by the end of 2023.

LG Electronics announced that it will begin to take pre-orders for its 2023 OLED TV range in a few days, and some of the TVs will begin shipping later this month. The company also announced the pricing of its new TVs.
