Sinovia demonstrates its roll-to-roll printed OLEDs at Display Week 2023

Sinovia Technologies developed roll-to-roll printed OLED production technologies, that enable the companies to produce simple (segmented) flexible OLED displays at low cost.

The company has a pilot OLED production line for smart labeling, packaging, etc. The company demonstrated some of its displays at Display Week 2023. Even thought these are low-cost solutions, the performance of the OLEDs is good, with over 10,000 operating hours.

The Fraunhofer FEP showcases its latest OLED microdisplays at Display Week 2023

During Display Week 2023, the institute demonstrated its latest displays, including the world's highest-density OLED microdisplays, reaching a PPI of 10,000 with a pixel size of only 2.5 um.

Fraunhofer's 10,000 PPI display was e a 0.18" 1440x1080 (monochrome) panel, produced on 300 mm wafers, using a 28 nm backplane process. The Fraunhofer also showcases ultra low-power microdisplays, and more technologies.

TCL CSoT shows new foldable and rollable inkjet-printed OLED prototypes

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.

AUO shows foldable, transparent and automotive microLED displays at Display Week 2023

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 shows its latest flexible OLEDs at Display Week 2023 and unveils the OLED Sensor Display

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.

UDC and PPG announce that their OLED production site in Ireland is starting production

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.

Carnegie Mellon researchers design a new EEOP powered haptic OLED device

Researchers from Carnegie Mellon University's Future Interfaces Group (FIG) designed a new haptic screen technology, which they call Flat Panel Haptics, that uses embedded electroosmotic pumps (EEOPs) that can move liquids quickly using electrical fields. 

The whole haptic layer is thin (just 1.5 mm thick) and can be placed behind a flexible OLED display to create an useful haptic display, as can be seen in the video above - buttons or keys can pop-up from the screen, and the interface can take advantage of shaped icons (like a play button or a stop button). Currently the shapes are pre-defined and cannot be altered by the user, but in the future this may change if the FPH technology is used to create small dot-matrix items.
