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.

MicroLED can be applied to displays of many kinds - from small displays for smartwatches and AR devices to large-area TV displays. MicroLED displays are often compared to OLED displays - the main display technology that it is rivaling.

What is an OLED?

OLED is the current premium emissive display technology, already adopted in many mobile devices, wearables and even TVs. In 2023 over 800 million OLED displays shipped to companies such as Samsung, Apple, LG, Sony and others. OLEDs can be made flexible, foldable and even rollable and the displays offer the best image quality currently in production.

MicroLEDs vs OLEDs

OLEDs use tiny sub-pixels made from organic emissive materials. Micro-LEDs are somewhat similar - but with an inorganic LED structure. Compared to OLEDs, Micro-LEDs promise to be much more efficient and bright, more durable (higher lifetime) and with a higher color gamut, mostly due to the superior performance of LEDs over their organic counterparts.

The following table shows a comparison between OLEDs and MicroLEDs (it also details mini-LEDs and regular LCDs):

As can be seen, microLEDs has the potential to beat OLEDs in most metrics, including power consumption, lifetime, brightness, temperature range and response time.

The main drawback of MicroLED technology is that it is not mature yet, and there are still challenges on the way towards commercialization, as current production costs are extremely high. It is believed that within 3-5 years microLEDs will be able to compete with OLEDs in some early markets (mostly wearables, near-eye microdisplays and ultra large-area TVs), and in the long term microLEDs represent the future of the display industry.

SID DisplayWeek 2023 - first microLED impressions

Display Week 2023, the industry's premier event, is now over, and it was a great week. We had dozens of meetings and saw many next-generation display technologies. As we go over all materials, we will upload new stories to detail the displays on show.

During the conference, we also hosted the first annual MicroLED Industry Association meeting, and were happy to see almost 40 people attending the meeting, and staying for several hours - discussing their latest technologies and exchanging information and news.

Here are our key takeaways from this show:

The US-China trade war may have implications on the display industry, and microLEDs in particular

In a new and interesting analysis, the Korea Times suggests that the US is considering adding display technologies, mostly next-gen displays OLEDs, to the list of restricted technologies and may ask Japan and Korea to stop selling materials and equipment to Chinese display makers.

Apparently the US government is still debating over this decision. OLED displays are used in defense applications, but OLED displays, unlike semiconductors, can be replaced with LCDs without effecting performance much, which means that hurting China's OLED industry will not have a strategic effect on China outside of the display industry. China today is the world's leading display maker by volume, but Korea is still leading in OLED display production. This decision, if happens will have more economic implications than strategic ones.
