Introducing The MicroLED Handbook

MicroLED-Info is proud to present The MicroLED Handbook. This book is a comprehensive guide to MicroLED display technology, industry and market. MicroLED displays are thin, efficient, bright and flexible and are on track to revolutionize the display industry.

The MicroLED Handbook

Reading this book, you'll learn all about:

  • MicroLED technology, materials and production processes
  • How MicroLEDs compare to LCDs and OLEDs
  • What are the challenges towards commercial production
  • LED technology and manufacturing processes
  • MicroLED driving and full-color architectures
  • The MicroLED displays currently on the market

Meet the MicroLED-Info team at MWC 2020

The MicroLED-Info team is excited to announce its attendance at the Mobile World Congress 2020 on February 24-27 in Barcelona, Spain. The Mobile World Congress (MWC) is the world's largest gathering for the mobile industry, organized by the GSMA. It features a large exhibition, conference programme and networking opportunities.

We are looking forward for a great event and great new microLED prototypes and technologies on display.

JBD demonstrates a 3 million nits microLED microdisplay

Shanghai-based Micro-LED microdisplay developer JBD unveiled two new Micro-LED microdisplay prototypes. First up is the JBD5UM720P-G, a 0.31" 720p (1780x720, 5,000 PPI) display that features a typical brightness of 3 million nits (!). This is a monochrome green (530 nm) display.

The second display, the JBD25UMFHD-B is a higher density display, at 10,000 PPI it achieves a 2560x1440 resolution in the same 0.31" size. This is a monochrome blue (455 nm) display that has a brightness of 150,000 nits. The display's refresh rate is 360Hz.

ITRI demonstrates a 16.7" tiled microLED display produced directly on PCB backplanes

Taiwan's Industrial Technology Research Institute (ITRI) demonstrated a 16.7" microLED display "module" that was produced by directly mass transferring micro-LED chips onto a PCB backplane.

ITRI developed its own mass transfer tech, and uses microLEDs provided by PlayNitride, PCB backplanes provided by Unimicron and drivers and assembly by Macroblock. The 16.7" display is made by tiling 15 modules 6x10 cm each (45,000 LEDs). The microLEDs are <100um in pitch.

Korean companies develop packaged RGB microLED technology for easier transfer process

Seoul Viosys and Seoul Semiconductors have jointly developed a new MicroLED technology, called Micro Clean LED that basically packages three separate LEDs (red, green and blue) into a single "one-single MicroLED pixel".

The idea is that these packaged colored pixels will be easier to transfer to the target substrate compared to the transfer of three different LEDs. The package itself does not contain any driver ICs.

KAIST researchers use 3D stacked MicroLEDs to enable high density displays

Researchers from the Korea Advanced Institute of Science and Technology (KAIST) developed a new process that enables the fabrication of highly dense MicroLED displays - up to 63,500 PPI (!).

The technique involves stacking RGB LEDs in three dimensions and a semiconductor patterning process. Stacking LEDs one on top of the other creates color interference issues, and to overcome this the researchers deposited an insulating film between the layers. This also improved the efficiency of the microLED devices.

Samsung to update its consumer MicroLED The Wall TVs in 2020

Samsung announced that it will introduce new modular MicroLED TVs for the consumer market (The wall Luxury) in 2020. Samsung says it takes advantage of "production improvements" to introduce new size options - and brighter panels.

In addition to the currently available 75, 146, 219 and 292 inch options, Samsung will now offer 88, 93, 110 and 150 inch displays, that will feature peak brightness of 5,000 nits (up from 2,000 in the previous models).
