US-based Rohinni announced that it has received initial orders for its Pixalux mini-LED and micro-LED placement solution. The company expects to ship more systems in the current quarter, and anticipates higher-volume market adoption in 2020.

Rohinni says that its system combines higher throughput and accuracy for small-die applications to provide a compelling and highly-competitive solution.

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.

China-based Tianma announced that it has developed a transparent 7.56" 720x480 (114 PPI) Micro-LED display. The new display, which will be demonstrated at SID next week features a transparency of over 60%.

Tianma says that the new display has an ultra-thin border of less than 0.8 mm (left and right). Tianma says that such durable and long-lasting transparent displays could be very suitable for automotive applications (such as HUDs or in-window displays).

In September 2018 it was reported that China-based Sanan Optoelectronics started to build its first micro-LED epitaxial wafer and chip production line and in early 2019 it was reported that Sanan plans to start sampling Micro LED chips as early as January 2019.

Now Sanan announced that it has signed a contract with the Gedian Economic and Technological Development Zone in China's Hubei Province to setup a 12 billion Yuan ($1.78 billion USD) Mini-LED and Micro-LED production site.

Market research firm Yole Développement has been following the Micro-LED market for some years with some very interesting insights and forecasts.

Yole's technology & market analyst Zine Bouhamri was kind enough to discuss Yole's Micro-LED views with us. Mr. Zine is is a member of the Photonics, Sensing & Display division at Yole and he's deeply involved in the business development of the Displays unit activities.

US-based Rohinni announced a new joint venture with China-based display maker BOE. The new JV (which will be based in China and controlled by BOE) will develop LCD mini-LED and micro-LED backlighting units.

The JV will adopt Rohinni's proprietary high-speed MicroLED placement technology that is capable of placing 50 die-per-second (dps) with 10 micron accuracy at 99.999% die yields. BOE and Rohinni will initially focus on large panel applications (32-inch and up) for consumer electronic products in addition to all display sizes for industrial, automotive and other markets

In September 2018 we reported that China-based San'an Optoelectronics is gearing up to setup its first micro-LED epitaxial wafer and chip production line in Q1 2019.

According to Digitimes, San'an now plans to start sampling Micro LED chips as early as January 2019. San'an says that micro-LEDs are not mature yet, but early trial adoption will begin in the second half of 2019 - for movie theaters, TVs and automotive displays.

According to Digitimes, China-based Sa'nan Optoelectronics is gearing up to setup its first micro-LED epitaxial wafer and chip production line in Q1 2019. San'an developed 20-micron micro-LEDs, and the company is now aiming to develop 4-micron LEDs and 10-micro LED flip-chips.

According to the report, San'an aims to start small-volume micro-LED production to be used for wearables, automotive taillights and large-area displays. The company's green and blue micro-LEDs are ready for commercialization, but its red chips still require development.

At the Touch Taiwan 2018 trade show, LED developer Lextar Electronics introduced its first micro-LED chips. The company unveiled two technologies - RGB chips and color conversaion chips - with both chips meeting the requirements of mass transfer processes.

Lextar micro-LEDs can be scaled down to 20 um - and feature a luminous efficiency of over 30%.

US-based Rohinni announced a new joint-venture with Magna Electronics to develop flexible mini-LED and micro-LED based lighting devices for the automotive market.

The new JV, controlled by Magna Electronics will be called Magna Rohinni Automotive Electronics and will be based in Holly, Michagan, US. In addition to the JV, Magna also made a minority equity investment in Rohinni.
