Micro-LED Production

ETRI researchers develop a highly efficient semiconductor chip packaging technology, applicable for microLED production

Researchers from Korea's ETRI institute developed a new chip packaging material, that is said to reduce the power consumption of the process by 95%, and reduce the number of required stages from 8 to 3. This could make semiconductors production much more efficient and lower in cost. 

The technology is applicable to all high-end semiconductor production - including microLED production. Indeed the team reports that they have reached out to several microLED developers to evaluate the technology, and the initial testing has been very positive. The material could be commercialized in three years.

JBD starts shipping full-color RGB microLED microdisplay samples

China-based MicroLED microdisplay developer Jade Bird Display have started shipping engineering samples of single-panel RGB microLED microdisplays. The company brands these new microdisplays as the Phoenix series, while its monochrome panels are now branded as Hummingbird. The Phoenix series is designed to be used with 50+ degree FOV waveguides.

JBD's first Phoenix samples are 0.22" panels, with a 2K resolution (2.5 um pixel pitch). The three LEDs (RGB) are all AlInGaN emitters, and are vertically stacked. JBD says that its plans for a standard product include a 0.3-inch panel with 4K resolution (2 um sub-pixel pitch. The company expects to begin full mass production in 2025.

HC Semitek starts building a $700 million microLED production line in Zhuhai, China

China-based HC Semitek is embarking on a 5 billion Yuan project (almost $700 million USD) to produce microLED wafers in Jinwan District, Zhuhai, China. The project will have three phases, with the first one (estimated at $275 million) has officially started last month.

HC Semitek hopes to light up the new production line in September 2024, and to start production by December 2024. When all three phases are complete, the new production line will have a yearly capacity of 58,800 microLED wafers (we do not the wafer size at this project, but we estimate these are 8-inch wafers). It is not clear from the reports, but this production line may also produce mini LEDs, not just microLEDs.

TrendForce: Apple delays the launch of its microLED smartwatch further to 2026

Apple has been developing microLED displays for wearable devices for many years, but the company and its production partners are not yet ready to initiate mass production. It was reported before that the company planned to launch the first microLED-powered watch in 2023, but this was delayed several times.

According to a new report by TrendForce, Apple delayed its microLED plans again, now hoping to introduce the first device in 2026. The main problem, as always, is the high production costs.

AU Optronics may close down its OLED fab as it focuses on microLED display technologies

According to reports from Japan, AUO is thinking about closing down its 4.5-Gen AMOLED production line in Singapore, as the company is shifting its focus on microLED display technologies.

AUO's first target it to start producing wearable microLED displays. It has reportedly signed a deal with Tag Heuer to supply it with smartwatch displays. In April 2023 AUO 'launched' its wearable microLED display, and it seems it is ready to begin small scale production. It will take time for AUO to expand production, as the path towards low-cost and mass-production of microLED displays (even for applications such as smartwatches) it not clear yet.

VueReal reports a major breakthrough in its microLED production technology

MicroLED developer VueReal says that it achieved a breakthrough in its MicroSolid Printing Platform, enabling it to go below 7um LED pitch (on the wafer) for full color microLED deposition. The company reports that its newest (and smallest) microLEDs show minimal impact on EQE, and this enables high-efficiency display production.

VueReal says that its new technology could soon compete on price with OLED displays while offering higher performance, and could be viable for many display segments - from wearables through smartphones to automotive and more. According to its current tests, its microLED displays will offer a brightness of 3,000 nits (and higher), while consuming around half the power compared to the latest AMOLED displays. In addition, its printing process is highly scalable and should not have a problem handling the demands of even the smartphone industry with hundreds of millions of displays per year.
