AUO had an impressive booth at Displayweek, showing some of its latest microLED prototypes. It is clear that the company is highly focused on microLED technology as its next-gen display strategy.
First up, with a 31" large area single-panel microLED, which AUO says is the world's largest. The display is produced on a single glass LTPS backplane, and offers 120Hz and a brightness of 500 nits. AUO calls this a Large Size A.R.T. MicroLED display.
The display industry's premier event, Displayweek, is over. We will now collect our notes, thoughts, photos and images and will share it all in the coming days. In the meantime, we'd like to detail some initial impressions.
Generally speaking, it seems as if the display industry is going through a phase of relatively little innovation, especially with the mature LCD and OLED industry segments. While it has been a very busy week, and attendance at the event seems high, the number of actual demonstrations and prototypes was not stellar and compared to previous years, the booths were smaller and some companies skipped the event this year or preferred to only show their latest displays in private settings. Some thoughts we have:
An interesting video surfaced, showing a small (reportedly 38-inch) microLED monitor prototype by Samsung, shown at a trade show:
We do not have any more information, but this is an interesting demo by Samsung. It is estimated that the monitor has a resolution of FHD (1920x1080), if Samsung is using the same tiles as the ones used in its TVs. It could be that this is not a tiled display, but we simply do not know at this stage.
Last week during Touch Taiwan 2024, AUO demonstrated several new (and not new) microLED display prototypes. The company released this short video showing the displays in action:
AUO showed its large-area (60") microLED displays, its automotive microLED solutions (including transparent automotive displays), a 30" real-depth 3D microLED display for entertainment applications, medical-grade displays and a 31" microLED display that is a single panel (not a tiled display) - which AUO says is the world largest.
In a recent announcement, Saphlux, Inc. revealed that its NPQD® Monolithic Full-Color Micro- LED (mLED) technology has successfully undergone a new round of technological upgrades. Following this advancement, the company has launched the enhanced T2 series micro-displays.
The Saphlux T series micro-displays incorporate core technologies, including NPQD® and large-scale silicon-based bonding, specifically tailored for the AR display applications. The series currently encompasses 0.12-inch monochrome single-color (red, green, blue) micro-displays and 0.39-inch monolithic full-color micro-displays.
MicroLED display developer VueReal demonstrated its latest microLED display prototypes at CES 2024.
In the video, you can see VueReal's 2um microLED microdisplays. These are monochrome displays, but VueReal says it will showcase its first full-color microdisplays in Displayweek 2024. VueReal's CEO Reza Chazi explains the company's approach and solutions.
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."
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 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.
