China-based Yeolight demonstrated new OLED lighting taillights designs at the Automotive Lighting Exhibition in Shanghai. In the video below you can see some of the various prototypes:
And in the photos below you can see some others. These are interesting prototypes. Some of these have been developed in collaboration with automotive makers, for example Geely-owned Zeekr.
Many years ago, The W Hotel in Taipei installed an OLED installation called You Fade to Light, designed by rAndom International creative studio and powered by Philips' OLED lighting panels. This beautiful piece consists of 2,000 modules, each lighting up as a response to people moving in front of it.
After several years these OLED panels started to fail (and fade, which is rather ironic given the installation's name), and now the hotel replaced the OLED panels with microLED-powered panels. It is said that the microLEDs achieved the same level of uniformity and light output of the OLEDs, maybe even surpassing them.
LG Display is demonstrating its new 30" and 77" transparent OLED displays for the first time, at the company's booth at K-Display 2023, in Seoul, Korea.

The new 30" transparent OLED offers HD resolution, while the 77" panel offers 4K resolution. All of LG's latest transparent OLED displays offer 45% transparency. LG showed its entire range of T-OLED displays in a coffee shop setting, in partnership with Starbucks.
An interesting video review shows a new repair system, based on lasers, that can fix defects in smartphone AMOLED displays. The system uses optical microscopy to find defects in operating OLED displays, and then a laser is used to fix the problems:
Such systems can be useful, but of course won't be able to fix all problems and defects in AMOLED displays, only ones that were caused by physical problems in conductive lines in the OLED module, that can be fixed by lasers. It will be interesting to see if these machines will truly find a place in the OLED repair aftermarket scene.
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.
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.
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.
China-based PMOLED maker Qingyue (previously part of Visionox) demonstrated its latest OLED and ePaper displays at Display Week 2023.
So first up Qingyue showed a large transparent segmented PMOLED display, this is the largest PMOLED ever demonstrated at 20.6" in size. It did not detail the transparent level, but this looked very good and was quite impressive.
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.
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.
