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 are introducing initial products on the market. In 2020, JBD became the first company to commercially produce microLED microdisplays - 0.3" VGA (640x480) monochrome (red, green and blue) displays. In 2023 JBD started shipping engineering samples of single-panel RGB microLED microdisplays.
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.

PlayNitride showcases its latest microLED displays at Display Week 2023
Taiwan-based MicroLED developer PlayNitride (a MicroLED Industry Association member) has demonstrated its latest microLED displays at Display Week 2023.
First up we have the company's tiled large-area microLED displays, called PixeLED Matrix. The company showed a 166" vertical installation, that is made from 324 modules. The total resolution is 1440x4860 (30 PPI, or a pixel pitch of 0.833 mm). This was a very nice looking demonstration.
Sitan shows its latest microLED microdisplays and transparent displays at Display Week 2023
China-based microLED display developer Sitan Technology demonstrated its latest microLED displays at Display Week 2023.
The company has developed four microLED microdisplays: 0.13" 1024x748 monochrome, 0.18" 800x600 monochrome, 0.18” 600x400 full-color and a 0.45" monochrome FHD panel. The company's 0.13" display offers a display density of 10,000 PPI (monochrome). The company also showed small transparent microLEDs.
Seoul Semiconductor unveils new vertically-stacked WICOP microLED prototypes at Display Week 2023
During Display Week 2023, Seoul Semiconductor demonstrated new prototype display modules that use its WICOP microPixel technology. WICOP Pixel is a full-color one-chip vertically-stacked microLED technology that does not require wire bonding, packaging, or lens, and enables easier microLED display production.
Seoul Semi updates that its latest WICOP Pixels reach a brightness of 10,000 nits (up from 4,000 in its previous generation technology).
Mojo Vision lit up its first 300 mm GaN-On-Silicon blue microLED wafer
AR microLED microdisplay developer Mojo Vision announced that it has achieved a process milestone and has lit-up its first 300 mm GaN-on-Silicon blue microLED array wafer. The company says it is on track to maturing its 300 mm CMOS fab process.
Mojo Vision is developing microdisplays based on blue LEDs and quantum dots color conversion. The company developed the world's highest density microLEDs, achieve up to 28,000 PPI (sub-micron LEDs).
Don't miss the upcoming webinar on the revolutionary microLED technology made accessible via EU-Project SMILE
Germany-based QubeDot, developer and producer of microLEDs and microLED-solutions, will be hosting an online seminar as part of the SMILE EU project. The webinar will be held on June 13th, 14:00-15:30 PM (CEST).
The revolutionary microLED platform SMILE has been developed as part of an EU-funded project that relied on a collaboration between several outstanding partners from Europe. SMILE stands for “Structured Micro Illumination Light Engine” and will enable an enormous variety of novel applications in the future. With full scalability in terms of pixel numbers, fast switching speed of freely programmable optical patterns, high optical power, multiple wavelengths, and the possibility of mass production, SMILE is the next generation of lighting technology. SMILE technology is addressing quickly increasing markets and applications such as AR glasses, photonic sensors, image projection, chip- based holographic microscopy and several more.
Q-Pixel announces a 5000 PPI microLED microdisplay based on its color-tunable single-pixel technology
US-based Q-Pixel announced that it has developed a 5000 PPI full-color microLED microdisplay, based on its proprietary Polychromatic microLED technology.
Q-Pixel's technology enables a single-pixel color-tunable microLED device. The displays are produced using a monolithic process. As the company is still in stealth-mode, we do not have more information, it will be interesting to know how this technology compares to Porotech's DPT color-tunable microLED technology.
Porotech demonstrates a 0.26" 1280x720 monolithic DPT full-color microLED microdisplay
Porous-GaN material platform developer Porotech has developed a single-panel full color MicroLED microdisplay, based on its Dynamic Pixel Tuning technology. The display is 0.26" in size, with a resolution of 1280x720.
The display is produced using a monolithic process, with a single LED epitaxial growth and a single-step wafer-to-wafer bonding to the CMOS backplane. The company says that the process is simple and that it offers high yields.
JBD says its new microLED fab in Hefei is now starting display production
In June 2022 it was reported that JBD is building a $92 million USD display production line in Hefei. JBD now says that its production line has commenced operation, and is producing microLED microdisplays.
According to reports, the production line will have an annual capacity of around 120 million panels (likely JBD's 0.13" monochrome variant).
MicroLED technologies at SID Display Week 2023 - what to expect
SID Display Week is the display industry's premier display show and this year's event, which will take place on May 21-26, should be an excellent one.
