At IFA 2019, TCL demonstrated its "The Cinema Wall" Micro-LED display - a 132" 4K display which features very high brightness (1,500 nits) and a wide color gamut. This is a tiled display that TCL demonstrated before at CES 2019. The display itself is produced by TCL's subsidiary CSoT.
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.
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).
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.
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.
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.
At the InfoComm 2019 US trade-show, LG Display unveiled a new 8K Micro-LED display. We do not have a lot of information about this display, only that the pixel pitch is 50 microns.
LG Display unveiled its first Micro-LED TV prototype in August 2018, a 173" TV. The company did not yet discuss the technology readiness of its Micro-LED displays.
