MicroLED Connect concludes a successful first virtual event

MicroLED-Connect is a hybrid event series, a year-long program of virtual and onsite events, all focused on the microLED industry. The first event took place last month, a 2-day virtual event that will be focused on microLED (and also miniLED) technologies. Over 25 speakers, including leading companies, researchers and market analysts, gave excellent talks.

The event offered a single track, so that the 120+ event participants could listen to all the talks, and also participate in online networking sessions. If you missed the event, you'll be happy to know that all the sessions were uploaded online, and can be accessed with a MicroLED-Connect yearly pass. Here in this post we share samples of two of the talks (only the first few minutes).

This is definitely the best on-line event for microLED and on-par with SID Display week for all events. Great program, format and easy to navigate - Eric Virey, Yole Group

"I enjoyed the conference very much and learnt a lot. I look forward to listening to couple of the talks I missed and of course see the pdf presentations" - Homer Antoniadis, independent consultant

"I really enjoyed the talks. The quality was very high and sessions were very informative. Looking forward to future events!" - Hossein Zamani Siboni, PhD, Director of Device Engineering, VueReal Inc."

XTPL launches an ultra-precise inkjet printing platform with support for microLED interconnection printing

Poland-based inkjet printing pioneer XTPL has launched its latest printing system, the Ultra-Precise Dispensing (UPD) System that enables the printing of high-precision electronically conductive or insulating structures.

The new systems are suitable for industrial production, and XTPL is targeting the display market, and specifically the microLED display market with its new systems. For microLED developers, UPD offers the ability to deposit precise conductive interconnections, supporting the integration of the microLEDs into heterogeneous microelectronic systems. These interconnections manage control, driving, and power distribution for microLEDs, expanding potential applications in AR/VR devices, smartwatches, automotive displays, and more.

Exaddon launches 20um 3D printed probes for microLED testing

Exaddon developed a unique micro 3D Printing technology that enables it to produce probes that can access and test pads and bumps with pitches of less than 20 micron. The company says that this unique method halves the current limit of fine-pitch probing, enabling microLED developers testing options that haven't been available before.

Exaddon's μ3D printing technology delivers high quality printed metal with micrometer resolution. Exaddon’s initial microLED test array is 3D printed directly on prepatterned traces with a pitch of less than 20 μm; This demonstrator validates Exaddon’s process on microPCBs for mounting on current probe heads. With 128 probes, the array gives microLED testers a 64x increase in efficiency.

MicroLED presentations from last year's microLED virtual meeting from UCSB, Coherent and Yole Intelligence

MicroLED-Connect is an upcoming hybrid event series, a year-long program of virtual and onsite events, all focused on the microLED industry. The first MicroLED Connect virtual event is coming up later this month, a 2-day virtual event that will be focused on microLED (and also miniLED) technologies. The event will include over 25 lectures from leading companies, researchers and market analysts. The series is organized by the MicroLED Industry Association together with TechBlick.

In this post we share three online presentations, taken from last year's online microLED event (November 2022). The first video, above, is from the SSLEEC group (led by Prof. Denbaars and Prof. Nakamura) at the University of California, Santa Barbara, that discusses the latest microLED research performed at this world-renowned group.

Avicena discusses its GaN microLED array chip-to-chip interconnects

Avicena, a developer of microLED-based chip-to-chip interconnects, discussed its solution at OCP Summit 2023. Avicena's LightBundle interconnect architecture is based on arrays of innovative GaN microLEDs that are integrated directly onto high performance CMOS ICs. Each microLED array is connected via a multi-core fiber cable to a matching array of CMOS-compatible PDs.

Avicena recently unveiled the world's first 1Tbps microLED-based Transceiver IC in 16nm finFET CMOS. The company says that its microLED-based LightBundle interconnects offers much lower power and latency, higher bandwidth and lower cost compared to current solutions based on VCSELs or Silicon Photonics.

PlayNitride helps replace an OLED lighting installation with microLED based panel area lighting

The W Hotel in Taipei has an old Philips OLED installation (called You Fade to Light, designed by rAndom International creative studio). This beautiful piece consists of 2,000 modules, each lighting up as a response to people moving in front of it.

Due to the limited lifetime of the OLED devices, after years of use the installation started to fail and fade (which is rather ironic, given its name). PlayNitride collaborated with the hotel to replace the OLED panels with microLED powered panels. Each single module included over 14,000 microLEDs, and in total there was over 30 million microLEDs - 20% more than the number of microLEDs in a 4K display.

Saphlux developed a 0.39" full-color microLED microdisplay using its NPQD color conversion technology

US-based Saphlux has developed a 0.39" full-color microLED Microdisplay, based on the company's NPQD color conversion technology. You can see a sample of Saphlux's T1-0.39 RGB display in the video below. 

Saphlux's first microdisplay offers a maximum white brightness of 250,000 nits, and a wide color gamut. The company is using high-EQE blue microLEDs (it has a partner that supplies the LEDs) and its NPQD technology achieves 67% photon conversion efficiency. The company's technology enables a pixel pitch of sub-2 microns.
