STRATACACHE to build the first MicroLED production line in the US, mass production expected by 2023

Global digital signage solution provider STRATACACHE is embarking on a project to construct a microLED display production line in Eugene, Oregon. The company aims to start production in this fab at around 2022-2023, with plans to adopt these microLED displays in its own solutions.

The new factory (E4) will be a complete microLED production line, from epiwafer (on 300 mm silicon wafers), through transfer process and to final module assembly. The company plans to produce a wide range of displays, from tablet-sized panels to large-area displays. Some of these displays will be flexible and transparent as the company sees a market demand for such technologies. The yearly capacity of the E4 is expected to start at a 1 million square meters per year.

PlayNitride launches new displays at SID 2020

PlayNitride introduced several new display technologies at SID DisplayWeek 2020. First up we have the PixeLED Matrix, which is a tiled microLED display module based display, each produced on its own PCB.

Each PixeLED module is made from 16 pixels (4X4), and can reach pitches of 0.3-0.4 mm. PlayNitride says that this technology can compete with mini LED displays, and says that it achieves a superior contrast and can also be fitted on curved surfaces. PixeLED displays can be used for TV displays, for commercial signage displays and also for automotive lighting. The display can currently achieve a maximum brightness of 2,000 nits.

We talk MicroLED displays with VueReal's CEO

Canada-based VueReal is a startup company that develop Micro-LED based microdisplays. The company's Continuous Pixelation micro-printing technology offers high density displays, high production yields and a simple design.

VueReal's founder and CEO, Reza Chaji, was kind enough to answer a few questions we had on the company's technology and business.

Reza, thank you for your time. Can you explain VueReal's micro-printing process and technology?

VueReal’s solution is a true printing process where you do not need to pick LEDs for each transfer. It is based on a cartridge design by VueReal that releases the LEDs selectively into the substrate.

Mikro Mesa develops a cost-effective 4" RGB mass transfer process

Taiwan-based microLED developer Mikro Mesa announced that it achieved a breakthrough in its microLED transfer and bond process, which now enables the company to transfer 2-5 um microLED chips using a large 4-inch stamp.

Mikro Mesa's new process can transfer color (RGB) vertically-structured microLED chips and create a full-color display. It can be used to create high-density dipslays - up to 1,800 PPI and be used to create large microLED TVs, over 55-inch in size. The new process is a low temperature one (below 200 degrees Celsius) and can be used on flexible substrates - and be also used to create transparent displays.

Lextar to demonstrate a 5.1" 30,000 nits transparent microLED display prototype

Lextar logoLED developer Lextar Electronics announced that next week at Touch Taiwan 2019 it will showcase a 5.1" transparent active-matrix microLED display that achieves an extremely high brightness - 30,000 nits.

This is Lextar's first public demonstration of a micro-LED display. Last year at Touch Taiwan 2018 the company unveiled its first micro-LED chips. The company recognizes that its micro-LED display technology will not be ready for commercialization before 2020 at the earliest.

See PlayNitride's latest flexible and transparent MicroLED prototypes

PlayNitride demonstrated its latest Micro-LED displays at SID DisplayWeek 2019, and the following recently-published video shows the company's booth and prototypes:

So first up we have a 7.56" 720x480 (114 PPI) transparent MicroLED display, which looks very impressive. This is the same Micro-LED display that TianMa demonstrated at its own booth. Interestingly, under direct light from it seems that the display is made from tiles - but PlayNitride says that the squares are made from the stamping process, and the company is developing technology that will remove these marks.

CSoT demonstrates a 3.3" transparent Micro-LED prototype produced in collaboration with PlayNitride

TCL subsidiary China Star (CSoT) demonstrated a 3.3" 232x116 transparent Micro-LED prototype display. The display is built on an Oxide-TFT (IGZO) backplane - CSoT says that this is the first such display ever demonstrated. The transparency is around 45%.

CSoT says that it developed the display in collaboration with PlayNitride that provided the transfer technology for CSoT.

Tianma's 7.56" transparent Micro-LED prototypes developed in partnership with PlayNitride

Earlier this week China-based Tianma unveiled a new 7.56" 720x480 (114 PPI) transparent Micro-LED display prototype at SID, and the display won SID's people's choice award - the best new display technology.

Tianma today revealed that the Micro-LED prototype was co-developed with Taiwan's PlayNitride. In 2017 PlayNitride started to sample micro-LED panels and shipped samples to 10-20 potential customers. The company's chairman and CEO, Charles Li, said in June 2018 that 5-6 of these customers are continuing the developing of micro-LED modules based on these panels. Apparently TianMa is one of these customers.
