Here is Glo and Kyocera's 1.8" microLED prototype

In June 2019 Micro-LED developer Glo announced a partnership with Japan-based display maker Kyocera to demonstrate a 1.8" Micro-LED display. Here's Kyocera's booth at CEATEC 2019 that features this display (03:00):

The Glo microLED display features a resolution of 256x256 (200 PPI), a peak luminance of 3,000 nits and a color gamut of 81% Rec.2020. The display's frame rate is 240Hz and the response time is 7 usec or less. For this demonstration panel, Kyocera provided the LTPS backplane and driving technology while glo provided its InGaN RGB micro-LEDs and its transfer technology.

Samsung Ventures invests in iBeam Materials to scale up its large-area LED production technology

iBeam Materials announced that it has received an investment from Samsung Ventures. iBeam developed a technology that can be used to produce LED chips on large-area flexible foils.

iBeam Materials, founded in 2011 in the US, is still at an early stage but this technology could enable the production of micro-LED devices directly on large-area flexible substrates without the use of a transfer (pick-and-place) process.

Sony reveals its Cystal-LED MicroLED display prices in Europe

HDTVTest posted an interesting video showing Sony's 110" Crystal-LED micro-LED display at Sony's Basingstoke UK office, at a joint event organized with AWE, a Sony distributor in Europe. The reviewer is highly positive about Sony's Micro-LED display quality:

AWE offers Sony's Crystal LED displays, which are custom made, but the company did release a general price guideline:

  • 146" display - 350,000 Euro ($390,000)
  • 182" display - 500,000 Euro ($550,000)
  • 219" display - 700,000 Euro ($780,000).

See PlayNitride's latest flexible and transparent OLED 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.

JBD demonstrates 2-million nits and 10,000 PPI Micro-LED microdisplays

Shanghai-based Micro-LED microdisplay developer JBD unveiled its latest Micro-LED microdisplay prototypes. JBD's panels can achieve a high brightness of 2 million nits coupled with very high pixel density (5,000 PPI) on a monochrome green display.

JBD also demonstrated an even high pixel density display (10,000 PPI). JBD can currently produce either monochrome or dual-color (red and green) microdisplays, and is developing full-color ones.
