PlayNitride aims to start trial production of Micro-LED displays by the end of 2017

Sep 10, 2017

PlayNitride's CEO, Charles Li, says that Micro-LED displays are not as challenging as originally expected, and the company now aims to start trial production of Micro-LED displays in the second half of 2017. The company has mass transfer and placement yield rates of over 99% in its lab.

In PlayNitride's R&D setup, it takes about 10 seconds to transfer and place 200,000 LEDs - which means that a 5" panel will take only 10 minutes to produce. However the cost for a single smartphone panel could reach about $300 - much higher than the cost of even the highest-end flexible OLED. Possible applications where Micro-LED displays could succeed commercially at this stage include smartwatches, VR / AR, automotive and transparent displays.

Yano Research sees the Micro-LED market growing from $7 million in 2017 to $4.5 billion by 2025

Sep 07, 2017

Japan-based Yano Research Institute estimates that following Sony's launch of its CLEDIS display, the Micro-LED market will finally emerge this year. Yano sees the micro-LED market growing from $7 million in 2017 through $14 million in 2018 and $224 million by 2020.

The fast growth will continue, and the micro-LED market wil reach $4.5 billion by 2025 - that's a total growth of over 65,000% from 2017 to 2025.

Unimicron to start producing PCBs for Micro-LED displays by 2019

Sep 01, 2017

Unicmicron LogoTaiwan-based PCB developer Unimicron has started to develop specific PCBs for Micro-LED displays, with aims to start mass producing such PCBs in 2019. According to LEDsInside, Unimicron will start a small batch production in 2018.

Unimicron is collaborating with Epistar's and ITRI's micro-LED display alliance, hoping that this will speed up the commercialization of its technology. LedsInside also reports that other Taiwan-based PCB makers aim to also start developing specific solutions for Micro-LED displays.

Apple patents a bi-directional Micro-LED display

Aug 30, 2017

A few days ago Apple was awarded with 52 different patents, covering a wide range of technologies that include 3D glasses, in-air gesturing, fingerprint sensing and more.

One of these patents details a Micro-LED device that is able to both emit and sense light. We have seen similar solutions based on OLEDs - in that case the photo-diodes were placed between the OLED pixels, to create a micro-display that can sense light (possible applications are for example eye-tracking in a VR headset).

Epistar: Micro-LED displays will not enter the market before 2019

Aug 24, 2017

Epistar logoDigitimes posted an interesting interview with Epistar's president, Jou Ming-Jiunn. Jou says that the most optimistic sceneraio is for micro-LED displays to enter production by the end of 2018, with real devices appearing in 2019. There are still challenges ahead though, and Epistar's customers have not yet committed to anything.

According to Jou, there are two main routes to the market for Micro-LED makers: VR/AR or wearable displays and large-area TV panels. It is not clear yet which will route will arrive first.

TrendForce sees 150 micron Micro LED-like displays arriving in the market next year

Aug 04, 2017

Market research company TrendForce says Micro LED displays still face several challenges. Commercialization of LED displays with small pitch sizes, which TrendForce calls "Micro LED-like" displays are expected by 2018.

TrendForce defines Micro LED displays as displays with LED size smaller than 100 microns. There are still several challenges ahead - with a major one being the the mass transfer of micron-size LEDs to a display backplane. Companies are now aiming to commercialize 150 micron displays as early as next year, and then will follow to develop processes to support small LED sizes.

KIMM researchers design a fast and reliable roll-to-roll micro-LED production process

Jul 30, 2017

Researchers from Korea's Institute of Machinery and Materials (KIMM) developed a new micro-LED manufacturing process based on a roll-to-roll transfer process. The researcher say that this kind of process may enable fast and reliable production.

The patented process is said to be much faster than conventional process, using an "ink-like" placement mechanism. The researchers say that in this process you can place more than 10,000 LEDs in a second - compared to about 1-10 LEDs per second in a conventional process.
