A discussion on MicroLED efficiency

MicroLED technology is regarded by many as a highly promising display technology, that could rival OLED in many applications in the future. We have been following microLEDs since 2018 via MicroLED-Info and are indeed excited by the progress and potential of this display technology.

One of the most talked-about advantage of microLED displays compared to OLEDs is the power efficiency. MicroLEDs are based on in-organic LEDs, which are inherently much more efficient than organic LEDs.

Sharp spits off display unit, to focus on microLED display technologies

According to reports from Japan, Sharp plans to split-off its display unit to a new company called Sharp Display Technology, or SDTC. According to the reports, SDTC will focus on MicroLED technology development.

SDTC will also, likely, take over Sharp's existing LCD factories (and OLED R&D lines). If this report is accurate, it is not clear what will be the future of Sharp's OLED projects.

Yole: the microdisplay market will grow to $4.2 billion by 2025

Yole Développement (Yole) says that the microdisplay market is set for impressive growth in the next few years, with the CAGR from 2020 to 2025 at 100%. Microdisplay module revenues will reach $4.2 billion in 2025, $1.8 billion of which will be for AR headsets.

This optimistic forecast has a warning though - it all depends whether next-generation display technologies will deliver on their promises - and whether actual use-cases will be found and commercialized.

The OLED and MicroLED Microdisplay Market Report

OLED-Info is proud to announce an important update to our OLED Microdisplay market report, which now adds a microLED microdisplay section. MicroLED technology shows great promise to enable extremely high-brightness and high-efficiency displays, but there are still challenges to overcome. The report now include details on all microLED microdisplay developers and includes more datasheets and product information - for both OLED and MicroLED microdisplays.


This market report provides a great introduction to both OLED and MicroLED microdisplays, and covers everything you need to know about next-generation microdisplays. This is a great guide if you're considering to adopt microdisplays in your product and if you want to understand this industry better.

Helio Display Materials develops perovskite-based materials for the display industry

Helio Display Materials, based in the UK, was spun-off from both Oxford and Cambridge University, to commercialize photoluminescent and electroluminescent perovskite-based materials for the display industry - with solutions for the OLED, LCD and Micro-LED markets.

Our sister site, Perovskite-Info, posted an interview with Helio's CEO, Simon B. Jones, discussing the company's technology and business.

MicroLED Microdisplays - quick market snapshot

This article is an extract from The MicroLED Handbook, 2020 edition, and gives a short introduction to the current market status of MicroLED Microdisplays. The handbook was published in January 2020 - there has been some updates since then, for example Plessey's recent soft-acquisition by Facebook and MICLEDI's technology was revealed.

There are several companies that develop microLED microdisplays, and these are gearing up to begin mass production of displays soon. It is likely that microdisplays will be the first type of commercial displays enabled by microLED technology.

Sea Change in Microdisplays Expected to Alter the Face of Computing

This is a guest post by Sri Peruvemba, Chair of Marketing, Society for Information Display

How will computing change in the coming years? The better question to ask is what won’t change. Thanks to a new platform, microdisplays and computing in general will transform how we communicate, how we live, even the way we express ourselves to each another. Ultimately, laptops, tablets, phones or smartwatches will go the way of the CRT. As will keyboards and mice. They’ll be replaced by innovative new wearables, inconspicuous devices that will interpret eye-blinks, voice commands, and hand gestures. A miniscule camera will follow your fingertips and body movements, allowing you to transpose images and text with ease, not unlike those depicted in Ready Player One.

The basic technology is here—used by Google, Microsoft, Oculus, MagicLeap, and other pioneers. And so is the demand. Refinements that improve performance and drive down costs are needed. But the world’s biggest players are on board. Form will follow function. Economies of scale will nosedive production costs. Within this realm, three display technologies have moved to the forefront. One appears to be slipstreaming those behind it into the 22nd century—microOLEDs.

Introducing The MicroLED Handbook

OLED-Info and MicroLED-Info are 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

DSCC updates its 2019-2025 OLED market forecasts

DSCC updated their display industry forecasts, saying that as LCD prices continue to fall it revises the capacity forecast downward by 6% as Display makers are delaying and cancelling LCD investments. DSCC's OLED capacity forecast is also reduced by 4% - and is now growing at a CAGR of 19% from 2016 to 2025 (the main reason is the cancellation of Visionox V2 phase 2 and LGD's E6 Phase 3).

OLED capacity by country (2016-2025, DSCC)

DSCC says that OLED TV roadmap is still not clear as Chinese makers are not ready to commit to OLED TV production. DSCC does see next-generation TV capacity coming online in the future - which could be inkjet-printed OLEDs, OVJP, MicroLEDs and other potential technologies. But the next-generation display market is certainly not clear yet and DSCC sees an extended forecast during which demand will outpace supply (especially as average TV size continues to grow).
