MicroLED Microdisplays

MicroLED technology is a next-generation emissive display technology that promises highly efficient and bright displays that offer superior image quality with infinite contrast and a wide color gamut. MicroLEDs are an excellent fit for microdisplays - as it can offer extremely bright and efficient displays with very fine pixel pitches.

Microdisplays are very small displays (usually under 1-inch) used in near-eye applications such as AR glasses, camera view finders and rifle sights. Most microdisplays on the market are either LCoS or OLED displays.

MicroLED Microdisplays

Many companies are developing high-end MicroLED microdisplays, and some of these are already offering initial products on the market. Some examples of such companies include Plessey (owned by Facebook), Jade Bird Display and Lumiode. MicroLED microdisplays are not in mass production, although some companies are already sampling simple monochrome displays.

Microdisplays use a high-end silicon backplane, and microLED microdisplays can be produced using a monolithic process - which means that the LEDs can be fabricated directly on the silicon wafer, or transferred to it in a process that is simpler compared to a TFT-glass transfer process.

Lumens developed a monolithic stacked RGB microLED epiwafer technology

Specialized Korea-based LED developer Lumens announced that it has developed a Monolithic RGB epitaxial wafers for micro-LED display production. The new technology stacks the three color LEDs on on top of the other on the wafer.

A stacked microLED architecture improves the performance, while also making the transfer process more productive. The company says that its design will offer a dramatic reduction in the production costs - especially the transfer process, which is reduced to a third (in terms of number of transfer steps), while also doing all the process from a single wafer.

Sundiode and Soft-EPI successfully grew a monolithic all-InGaN stacked-RGB LED structure

Stacked-RGB microLED microdisplay developed Sundiode announced that it has achieved the successful growth of a monolithic, all-InGaN RGB LED structure on a single sapphire wafer. This structure was developed in collaboration with Soft-EPI.

Sundiode's epitaxial technology enables stacked-RGB LEDs with multiple junctions, capable of emitting RGB colors independently. This structure makes it easier to produce ultra-high density microdisplays.

MICLEDI demonstrates AlInGaP "Ferrari" red microLED devices

Belgium-based microLED microdisplay developer MICLEDI demonstrated a "Ferrari" red microLEDs on aluminium indium gallium phosphide (AlInGaP) starting material. The company says that these red microLED devices are produced using a CMOS-compatible flow, free of arsenide.

MICLEDI says that it uses advanced photolithography available in 300mm wafer fabs. The company's first red microLED on GaN is solidly in the red range with wavelength centered at 620nm and good full-width half-maximum (FWHM) of <50nm. This newest announcement of red on AlInGaP achieves 653nm wavelength at extremely narrow FWHM of <9nm.

The MicroLED Industry Association to host an AR microLED technology webinar

On February 7th the MicroLED Industry Association will host a private webinar on microLED technologies for the AR market. The AR market is a very good segment for microLED developers, as it offers high performance requirements, relative microLED maturity and an excellent horizon.

The upcoming Seminar will feature four world-leading speakers, and will also be open to a Q&A session, to help increase microLED developers knowledge and involvement in the AR industry:

  • Karl Guttag: a display systems engineer, one of the most respected experts on near eye displays and HMD designs
  • Assaf Levy-Beeri: CEO at JoyaTeam, an optical design team focusing on AR solutions
  • Soon-gi Park: AR specialist at LetinAR, a Korea-based AR optical system developer
  • Reza Chaji: CEO at microLED microdisplay developer VueReal (and a microLED association member)

Reports suggest that Meta is in talks with Samsung and LG regarding the future supply of microLED microdispaly

In August 2022, we posted that both Samsung Display and LG Display started to develop microLED microdisplay technologies. According to a new report from Korea, Meta is in talks with both Korean companies regarding the future supply of both OLED and MicroLED microdisplays.

ITRI announces new microLED microdisplay technology for AR applications

Taiwan's Industrial Technology Research Institute (ITRI), is introducing its latest microLED microdisplay technologies, and unveils its latest microdisplay prototype.

The 0.5" display offers full-color images (using blue LEDs and quantum-dots based color conversion), high resolution (over 2,000 PPI) and high brightness (over 20,000 nits). The display offers high power efficiency - ITRI says it consumes less than half the energy of current solutions (likely compared to OLED microdisplays).

DSSC sees the microLED market growing to $1.3 billion in 2027, led by wearable displays and microdisplays

DSSC says that microLED display revenues will grow from around $40 million in 2023 to over $1.3 billion in 2027. While this is fast growth, it means that DSCC does not believe microLED will penetrate large display markets at least until 2028, and indeed the analysts say that lowering production costs will be necessary before microLEDs can become competitive against OLEDs and LCDs.

DSSC sees microLED microdisplay, produced using a monolithic process, taking up about 25% of the microLED display market. The largest segment for microdisplays will be smartwatches or wearable displays - as the low pixel size (relative to other display segments, at least) means that microLED technologies is relatively mature for that segment.
