With growing interest in MicroLEDs, DSCC is proud to announce a new report on MicroLED Display Technology and Market Outlook.

MicroLEDs have garnered a lot of interest because of the potential advantages over other flat-panel display technologies, most notably in high efficiency, high brightness, high color saturation, faster response rate, and longer lifetime. This unique combination of features would make MicroLED the superior display for many applications, ranging from super large TVs to microdisplays for use in AR/VR headsets. The ability to withstand harsh environmental conditions is also particularly attractive for the automotive industry.

MicroLEDs have generated a lot of hype, but also a lot of confusion amongst the mainstream media. This is because MicroLED displays can be manufactured in different ways, and each one will bring its own set of challenges and possible applications.

The report covers the two general manufacturing methods: monolithic or mass transfer. The monolithic approach is the preferred route to make microdisplays that are below 1-inch in diagonal and with a very high pixel density above 5,000 PPI. These miniature displays are very promising for AR/VR since they can achieve millions of nits in brightness without sacrificing contrast or compactness. However, obtaining a full color display has proven to be a challenge.

The mass transfer approach consists in moving a large number of individual MicroLEDs on the display substrate. This method can, in theory, produce displays of any size, including large TVs above 100-inch in diagonal. There are currently several mass transfer technologies under development.

Samsung has already started selling luxury MicroLED video walls to consumers. However, the LED chips on these displays are still larger than 100 μm, which is the commonly accepted size definition for a MicroLED. Future MicroLED TVs will be based on smaller LED chips, which will help reduce the total BoM of the display. However, shrinking the LED chips too much can have an impact on efficiency and affect the performance of the display.

The report covers all these issues in detail and shows the various solutions under development by the MicroLED industry. The report also includes market forecasts to 2027, segmented by applications.
