Tianma demonstrated new microLED technologies at SID Displayweek 2021

Tianma demonstrated several new microLED display prototypes at SID Displayweek 2021. First up is a 7.56" 720x480 (114 PPI) flexible MicroLED display, developed in collaboration with PlayNitride. The display is driven by an LTPS backplane and achieves a brightness of over 600 nits. The bending radius is 50 mm.

The second display is a tiled display that combines two 5.04" 480x320 (114 PPI) LTPS microLED displays. This one was develop again in collaboration with PlayNitride. The border (bezel) of the panel is less than 0.03 mm - although looking carefully at the display you can see a black line separating the two panels.

AU Optronics shows its microLED display prototypes at SID Displayweek 2021

AUO Optronics is showing its latest microLED ALED display prototypes at SID DisplayWeek 2021. Most of these aren't new display (AUO already demonstrated these last month) but it's the first time we got these on video:

You can see the 1.39" 472x472 (338 PPI) full-circle microLED display, developed together with PlayNitride. You can also see AUO's 12.1-inch 169PPI microLED display it first demonstrated in SID 2020, and the 9.4-inch 228 PIP flexible microLED prototype it also developed together with PlayNitride.

3D-Micromac launches a new microLED LIFT mass transfer tool

3D-Micromac announced a new microLED mass transfer tool, called microCETI. The company says its new technology can be used to transfer over 130 million microLEDs per hour.

MicroCETI is based on a laser-induced forward transfer (LIFT) process that can support almost any microLED material and shape. The tool also includes optional modules - a laser lift-off (LLO) module, and a single LED die repair module.

GE and Current Lighting Solutions to develop PFS/KFS phosphors for microLED applications

GE and Current Lighting Solutions have signed a collaboration agreement on small-size Potassium Fluorosilicate (PFS/KSF) phosphor for MiniLED and MicroLED applications. The two companies have a long-standing relationship in the world of PFS/KSF phosphor, and this new agreement extends their previous agreements.

The two companies will develop advanced versions of KSF Red Narrowband phosphor with material properties required to enable the use of these materials in advanced display technology such as emissive microLEDs. GE has the exclusive rights to license KSF technology for display applications and will work with display companies to license KSF technology into these advanced displays.

KAUST researchers develops highly-efficient GaN and InGaN red microLED devices

Researchers from King Abdullah's University of Science & Technology (KAUST) in Saudi Arabia developed GaN and InGan red microLED devices that are highly efficient.

The researchers managed to increase the efficiency of their previous design by a new chemical treatment that removes damages at the microLED sidewalls (created during the fabrication process) and also retains the high crystal quality at the InGaN and GaN sidewall interfaces.

Omdia: the MicroLED market will reach $7 billion in sales in 2025

Omdia published a very interesting article, detailing the company's view on the microLED market - including its latest market forecast

MicroLED display shipment by application forecast (2020-2027, Omdia)

Omdia sees 5 million microLED display shipping in 2025, which the company says will generate $7 billion in revenues. In 2027, the market will grow to over 11 million units. Omdia lowered its forecast from 2020 (back then it projected 16 million display shipments in 2027).

Here are more details on Lextar's 10.6-inch transparent microLED display prototype

Last week we reported that Ennostar Incorporation (formed by a merger of Taiwan's Epistar and Lextar in 2020) demonstrated a 10.6" transparent microLED display at Touch Taiwan 2021. We now have more information on Lextar's new display prototype.

This square display features a 640x640 resolution (85 PPI) and uses LED chips that are <50 um in size. This is a TFT-based display (LTPS? we're not sure) that achieves a transparency of 61%, a brightness of 3,000 nits (peak value) and a 120Hz refresh rate.

Rohinni designed a parallel-design for its miniLED bondhead equipment to achieve 14X placement speed boost

Micro-LED and mini-LED developer Rohinni announced that the company has developed a new design for its miniLED composite bondhead, which now allows multiple bondheads to run in parallel. Rohinni says it has been able to accelerate its miniLED deposition speed 14X compared to 'competing technologies'.

With the new system, Rohinni demonstrated >99.999% placement yield and scalability at speeds< greater than 100 die per second. said that it developed a new placement technology for mini-LED that doubles the placement speed compared to its previous technology.

eLux installs a new automated fluidic assembly R&D tool, unveils a new microLED display prototype

USA-based eLux was established in 2016 as a spin-off from Sharp Labs of America, to commercialize a unique MicroLED production technology. A year ago we discussed the company's technology and business with its CEO, Jong-Jan Lee.

eLux automated fulidic assembly tool, 2021

Today eLux announced that it has installed an automated fluidic assembly tool at its prototype fab in Taiwan. The new tool features fully automatic cassette-to-cassette fluidic assembly of ten display panels, each up to 15-inch in size. The tool has provisions for capture and recycle of microLEDs and assembly fluids to minimize operating costs, and its capacity can be expanded by adding two additional modules.
