MicroLED (also written micro-LED or µLED) is a display technology in which each pixel, or each colour subpixel, is a microscopic inorganic light-emitting diode that emits its own light. The diodes are usually made from gallium nitride (GaN) and related III-nitride alloys such as indium gallium nitride (InGaN), the same material family used in LED lighting. A microLED panel is self-emissive like an OLED panel and needs no backlight or colour filter, unlike a liquid-crystal display, but its inorganic emitters tolerate far higher brightness and do not suffer the burn-in of organic materials.[1][2]

The technology covers two very different product classes: very large direct-view screens assembled from modules, and tiny near-eye microdisplays built on silicon chips for augmented reality (AR) and, much less so, virtual reality (VR). In XR the microdisplay matters most, because microLED can reach brightness levels that no other microdisplay technology matches. That brightness is what makes it the leading candidate for see-through smart glasses that must stay readable outdoors after a waveguide display has thrown away most of the light.[3][2] Its main limits are manufacturing ones: efficient red emitters and full-colour panels at micrometre pixel pitch are still difficult, and moving millions of diodes onto a backplane at high yield is expensive. MicroLED glasses on sale have mainly used monochrome green panels, and full-colour microLED projectors are recent, such as JBD's Hummingbird II (September 2025) and Roadrunner (December 2025).[4][5]

How it works

Nine green inorganic emitters sit above and connect to a silicon CMOS driving backplane; arrows indicate emitted light toward the viewing optics.
A simplified monochrome microLED microdisplay places inorganic light emitters above a silicon CMOS driving backplane. This is an illustrative architecture, not a manufacturer cross-section.


A microLED is a conventional inorganic LED shrunk to micrometre scale. As in any LED, electrons and holes recombine in a semiconductor junction and emit photons; InGaN quantum wells give blue and green light efficiently, while red has traditionally come from aluminium gallium indium phosphide (AlGaInP) or from InGaN with high indium content.[2][6] Because each pixel emits light directly, a pixel that is switched off emits nothing, which gives true black and very high contrast in the same way as OLED.[1] Huang, Hsiang, Deng and Wu note that the response time of micro-LED, mini-LED and OLED chips is several orders of magnitude faster than that of liquid crystals, and they list a luminance above 10,000,000 cd/m2 and a pixel density above 5,000 pixels per inch as requirements that micro-LED microdisplays already meet for AR.[2]

In a display the diodes sit on a driving backplane. A transistor backplane, often active-matrix, controls each emitter, and pulse-width modulation sets its brightness.[1] Backplanes can be printed circuit boards, glass or silicon.[1] Large screens place separately grown red, green and blue dies on the backplane, a step known as mass transfer. Near-eye microdisplays instead bond a whole LED array, grown on one wafer, to a silicon CMOS (complementary metal-oxide-semiconductor) driver chip, which gives very high pixel density on a single small panel.[4][7] JBD's current platform, for example, reaches 10,160 pixels per inch with a 2.5-micrometre pixel pitch on a 0.1-inch panel.[8]

History

MicroLED research began with the group of Hongxing Jiang and Jingyu Lin at Kansas State University. In their own account, the team saw blue light from a 12-micrometre InGaN/GaN microLED under a microscope in August 1999 and reported the result at the Materials Research Society fall meeting in Boston that year.[9] The paper "GaN microdisk light emitting diodes" by S. X. Jin, J. Li, J. Z. Li, J. Y. Lin and H. X. Jiang appeared in Applied Physics Letters in January 2000; it described microdisk LEDs about 12 micrometres in diameter and found that, for the same area, their quantum efficiency was higher than that of conventional broad-area LEDs.[10][11] Their patent, US 6,410,940, "Micro-size LED and detector arrays for mini-displays, hyperbright light emitting diodes, lighting and UV detector and imaging sensor," disclosed LEDs around 20 micrometres in size and microLED arrays.[12]

In November 2000 the group built a passively addressed 10 by 10 blue microdisplay with 12-micrometre pixels, published in February 2001.[9][13] A video-capable display needed each pixel driven by a CMOS circuit, and the researchers say no agency would fund that until 2007, when their company III-N Technology received support from the US Army's Night Vision and Electronic Sensors Directorate. Working by then at Texas Tech University, they delivered blue and green VGA (640 by 480) microdisplays to the Army, which had to dim them with neutral density filters to see details, and published the actively driven microdisplay in Applied Physics Letters in July 2011.[9][7] The 2011 device had 12-micrometre pixels on a 15-micrometre pitch, emitted at 462 nm (blue) or 517 nm (green), and was flip-chip bonded to a silicon CMOS active-matrix driver with indium bumps.[14]

Large direct-view products came first commercially. Sony showed a 55-inch, 1,920 by 1,080 "Crystal LED Display" prototype built from about 6 million RGB LEDs at CES in January 2012,[15] and in 2016 announced CLEDIS (Crystal LED Integrated Structure), a bezel-less modular system whose pixels each occupy only 0.003 mm2.[16] Samsung showed "The Wall," a 146-inch modular microLED television, at CES 2018.[17] Large technology companies also bought microLED start-ups: Apple acquired LuxVue Technology in 2014,[12] and Google announced its acquisition of Raxium, a developer of single-panel microLED displays, in May 2022.[18]

The first commercial microLED microdisplays for AR followed. On 12 October 2020 Jade Bird Display (JBD) announced that it was about to begin production of a 0.13-inch, 640 by 480 single-colour (red, green or blue) panel with 4-micrometre pixels.[19] Consumer glasses using JBD panels were on sale by 2024, including the Even Realities G1 and the Vuzix Z100.[20][21][22]

Why microLED suits AR

See-through AR glasses carry the image from a tiny display through an optical combiner, usually a waveguide, into the eye. Waveguides, and diffractive ones in particular, are very inefficient. Karl Guttag lists the causes: pupil expansion, etendue loss, losses at the diffraction gratings, and the need to collimate the roughly Lambertian output of an LED, which is often done with microlens arrays. Only a tiny fraction of the light that enters reaches the eye, so a display must supply millions of nits at the source to deliver thousands of nits to the eye.[3] Mojo Vision chief executive Nikhil Balram told IEEE Spectrum that waveguide efficiency is below 1 percent and that 10,000 nits at the eye, enough for a sunlit scene, needs more than a million nits from the display.[6]

Guttag describes microLED microdisplays as hundreds to over a thousand times brighter than Micro-OLED microdisplays, which is why they are paired with waveguides despite their colour limitations.[3] A self-emissive panel also removes the separate illumination optics that a liquid crystal on silicon (LCoS) projector needs. UploadVR, reporting on Meta Orion, described its microLED projectors as smaller and more power efficient than the LCoS projectors in competing devices, and Meta called them "super small and extremely power efficient."[23][24] A 2024 study in PhotoniX likewise names brightness under strong ambient light as a critical obstacle for AR and mixed reality, and presents GaN micro-LEDs as the leading candidates to solve it.[25]

Comparison with other display technologies

The display technologies used in VR and AR headsets differ in how each pixel produces light, which sets their brightness ceiling, contrast and suitability for see-through optics.

Technology Emission Separate light source Strengths Limits for XR
MicroLED Self-emissive, inorganic LED No Very high brightness (microdisplays demonstrated in the millions of nits), true black, long life, no organic burn-in[2][22] Full colour at micrometre pitch is difficult, red efficiency is the main obstacle; costly mass transfer or monolithic yield issues[4][26]
OLED / Micro-OLED Self-emissive, organic No True black, very high pixel density on silicon, mature[2][27] Far dimmer than microLED at microdisplay scale; burn-in and ageing at high luminance[2][3]
LCD Transmissive liquid crystal Yes (LED backlight) Low cost, mature Response several orders of magnitude slower than emissive LED and OLED chips[2]
LCoS Reflective liquid crystal on a CMOS chip Yes (illumination LEDs) Field-sequential full-colour projectors used in shipping AR glasses[28] Needs separate illumination optics; projectors larger and less power efficient than microLED ones[23]

Micro-OLED (OLED on silicon) is the more mature high-density rival. IEEE Spectrum reported that the Apple Vision Pro uses a micro-OLED display with 7.5-micrometre pixels and a maximum brightness of 5,000 nits, and wrote that microLED might one day replace micro-OLED in enclosed headsets of that kind.[6] TrendForce's 2023 comparison judged that microLED beats micro-OLED in contrast, lifespan and power efficiency but that integrating RGB remains a challenge.[27]

The red microLED problem

Red is the hardest colour to make efficiently at small sizes. Pushing InGaN to red wavelengths requires more indium, a large atom that disrupts the crystal; Balram described efficiency as "falling off a cliff" as indium is added.[6] The conventional alternative, AlGaInP, is efficient in large LEDs, but its external quantum efficiency (EQE) falls sharply as the device shrinks, and its higher refractive index also lowers light extraction.[29][2] Size makes both worse: Huang and colleagues note that below a chip size of 50 micrometres peak EQE drops, citing sidewall emission and insufficient light extraction, and that the higher surface-to-volume ratio of small chips aggravates losses from Shockley-Read-Hall non-radiative recombination.[2]

A 2024 US Army research solicitation stated that existing red micro-LEDs show EQE as low as 0.1 percent when smaller than 5 micrometres, and asked for red devices of 2 to 5 micrometres with EQE above 2 percent.[26] Research groups have approached that target from several directions:

Year Group Result
2021 Li, Nakamura, DenBaars et al. 611 nm InGaN red micro-LEDs with peak EQE of 2.4 to 2.6 percent that stayed nearly constant as device area shrank from 100 by 100 to 20 by 20 micrometres[29]
2023 Li, Nakamura, DenBaars et al. InGaN red micro-LEDs with a peak EQE of up to 6 percent[30]
2023 Hsiao, Kuo et al. Analysis of InGaN red micro-LEDs with dense V-shaped pits, which are thought to reduce non-radiative recombination[31]
2026 Sanyal, Pasayat et al. Single 2-micrometre InGaN red micro-LEDs on porous pseudo-substrates with a peak EQE of 2.71 percent at 630 nm, which the authors describe as the highest reported for single InGaN micro-LEDs under 5 micrometres emitting beyond 620 nm[32]

Another route avoids native red emitters altogether: a blue micro-LED is covered with a colour-converting layer such as quantum dots. Mojo Vision layers quantum dots on blue GaN micro-LEDs to shift their output to red,[6] and Huang and colleagues report that quantum-dot colour-converted micro-LED displays have reached 93.1 percent of the Rec. 2020 colour gamut in experiments.[2] Porotech's porous GaN material is engineered to let InGaN emit red, and its Dynamic Pixel Tuning drive method lets a single microLED produce different visible colours.[33]

Manufacturing challenges

Wu and colleagues identify two main obstacles to moving micro-LEDs from the laboratory to the market: raising the yield and cutting the cost of mass transfer, and producing full colour from micro-LED chips. They group full-colour methods into three families: transfer of separate red, green and blue chips, colour conversion, and single-chip multi-colour growth.[4] Huang and colleagues likewise list mass-transfer yield and defect repair as major challenges that directly affect cost.[2] Near-eye microdisplays avoid per-die transfer by bonding a whole array to a CMOS backplane,[7] but defective pixels still matter: JBD said it cut the allowed defective pixels per panel from 100 or fewer to 3 or fewer in May 2025.[5]

Wafer size is a further cost issue. JBD says advanced silicon backplanes have moved to 12-inch wafers while microLED epitaxial wafers remain mostly 4-inch, and that dicing the backplanes to match caps their utilization at 77 percent. In May 2026 it announced a move from a 4-inch architecture to a 12-inch "reconstructed wafer" process, in which sorted LED dies are placed on a 12-inch carrier and bonded to a matching silicon backplane.[34] Substrate quality matters too: the 2024 PhotoniX study grew GaN-on-GaN micro-LEDs with threading dislocation densities of about 10^5 per cm2, three orders of magnitude lower than GaN on sapphire, and showed a 3,000 pixels-per-inch microdisplay with better uniformity and luminance than a sapphire-based equivalent.[25]

Cost and complexity have stopped some programmes. In March 2024 Bloomberg's Mark Gurman reported that Apple had cancelled its in-house microLED display project, first aimed at the Apple Watch Ultra, after concluding that it was not economically viable. Apple kept OLED for the watch but was still considering microLED for other products.[35]

Companies and products

Several specialist firms make microLED microdisplays for AR and other near-eye uses.

  • Jade Bird Display (JBD), founded in 2015,[36] supplies microLED microdisplays to smart glasses makers. It says its panels were in more than 30 announced AR smart glasses by the end of 2024, including DreamSmart StarV Air2, Rokid Glasses, INMO GO2, Vuzix Z100 and OPPO Air Glass 3, and in nearly 50 models by the end of 2025, including the Alibaba Quark AI Glasses and RayNeo X3 Pro.[22][5] In 2024 it reported record panel brightness of 10 million nits for green, 2 million for blue and over 1.5 million for red, launched the Hummingbird I polychrome module rated at 6,000 nits through diffractive waveguides, and said its native monolithic RGB Phoenix series had passed 2 million nits, with custom products scheduled for mass production in the third quarter of 2025.[22] Its Roadrunner II polychrome projector, launched in June 2026, uses a 0.1-inch, 800 by 600 panel refreshing at 480 Hz and occupies 0.18 cc.[8] In July 2026 JBD announced joint work with XPANCEO on a microLED microdisplay for smart contact lenses.[36]
  • Kopin Corporation agreed with JBD in January 2021 to develop a monochrome 2,048 by 2,048 microLED display of about 1 inch diagonal for see-through AR and mixed reality, with JBD supplying LED wafers and hybrid bonding and Kopin the silicon backplanes.[37]
  • Porotech, a University of Cambridge spin-out,[33] develops the PoroGaN material and Dynamic Pixel Tuning, which it announced in May 2022 as a way to make full-colour or tunable-colour displays from identical pixels on a single wafer.[38] In December 2023 it formed a partnership with Foxconn (Hon Hai) to build microdisplays for AR and wearables.[33]
  • Plessey Semiconductors agreed in 2020 to provide its microLED technology to Facebook (now Meta Platforms) for AR and VR prototypes.[39] In January 2025 Plessey and Meta announced a red microLED display for AR glasses rated at up to 6,000,000 nits with a pixel pitch below 5 micrometres; Plessey said it dedicates its manufacturing operations to Meta under a long-term commercial agreement, and that the work uses its GaN-on-silicon platform and manufacturing facility in Devon, UK.[40]
  • Mojo Vision originally built the Mojo Vision Lens, an AR contact lens with a tiny microLED display. In January 2023 it stopped work on the lens, citing difficulty raising capital, and laid off about 75 percent of its staff to focus on microLED displays.[41] With a US$22.4 million Series A in April 2023 it listed dynamic displays of up to 28,000 pixels per inch, sub-micrometre blue micro-LEDs, quantum-dot red and green, and brightness above 1 million nits.[42] IEEE Spectrum reported a Mojo red microLED 1.37 micrometres across on a 1.87-micrometre pitch.[6] In September 2025 Mojo closed a US$75 million Series B Prime round led by Vanedge Capital, bringing its total funding to US$345 million.[43]

Use in AR and VR hardware

In headsets and glasses microLED serves as a microdisplay feeding the viewing optics, not as a large direct-view panel. Early microLED glasses and reference designs used monochrome green panels paired with waveguides:

Product Availability MicroLED display details
Vuzix Z100 General availability 20 November 2024, US$499 Monocular monochrome waveguide display in a 38-gram frame; JBD lists it among its microLED customers[21][22]
Vuzix Ultralite (reference design) Shown at CES 2023 JBD green-only 640 by 480 microLED with a Vuzix waveguide; Vuzix claimed up to 4,100 nits[3]
Even Realities G1 2024 Even Realities lists a green 640 by 200 micro LED display, 1,000 nits, 25-degree field of view and 20 Hz; Guttag identified a JBD 640 by 480 green microLED panel with a diffractive waveguide, only part of which is used for content[44][20]
Even Realities G2 Orders opened 12 November 2025, US$599 Green microLED, 640 by 350, 1,200 nits, 60 Hz, 27.5-degree field of view[45]
Rokid Glasses Announced by the end of 2024; Rokid said shipping would start in November 2025 Two JBD monochrome green microLED microdisplays, which MicroLED-Info believed to be 0.13-inch VGA panels[46][22]

Meta Orion, shown in September 2024, uses microLED projectors that feed silicon carbide waveguides for a field of view of about 70 degrees.[24][47] It is an internal development device, not a product: UploadVR reported an angular resolution of about 13 pixels per degree and a cost on the order of US$10,000 per unit.[23] The consumer Meta Ray-Ban Display (2025) uses an OmniVision LCoS microdisplay with field-sequential colour and a Lumus reflective waveguide instead. Guttag wrote that he could understand the argument that microLEDs were "not yet ready for prime time" for full-colour displays, and added that LCoS might remain the better full-colour solution for some time.[28] TrendForce wrote in 2023 that microLED AR glasses predominantly display monochrome images because of colorization barriers.[27]

MicroLED is used much less in VR than in AR. An opaque VR head-mounted display does not lose most of its light in a waveguide, so it does not need microLED's extreme brightness, and it needs large, dense, full-colour panels that microLED still struggles to make affordably.[3][2] Huang and colleagues estimate that a 100-degree field of view free of the screen-door effect needs 6K by 6K resolution, which on a 2-inch panel means about 3,000 pixels per inch and chips smaller than 5 micrometres.[2] Current high-end headsets use micro-OLED: the Apple Vision Pro,[6] and Meta VR Glasses, announced in September 2026 with 2,412 by 2,288 micro-OLED panels per eye.[48]

Research

Academic reviews treat microLED as one of the main candidate display sources for AR and VR near-eye displays. Xiong, Hsiang, He, Zhan and Wu's 2021 review of AR and VR displays covers micro-LED fabrication and properties next to holographic optical elements and metasurfaces,[49] and Lin and Jiang's 2020 perspective lists virtual reality displays among microLED's application areas.[11] Active research areas include efficient red and full-colour emitters, emitter sizes below 5 micrometres, native-substrate epitaxy to cut defects, and wafer-scale bonding to CMOS backplanes.[26][25][32][34]

Current status

As of September 2026 microLED is in commercial AR use mainly as monochrome green microdisplays in see-through smart glasses, with JBD reporting nearly 50 glasses models using its panels by the end of 2025.[5] Full-colour microLED projectors such as JBD's Hummingbird II (launched September 2025) and Roadrunner series have been launched, while the full-colour Meta Ray-Ban Display uses LCoS instead.[5][8][28] Newly announced VR headsets such as Meta VR Glasses still use micro-OLED panels.[48] MicroLED's wider use in XR depends on efficient red and full-colour emitters and on cheaper production at volume.[4][34]
