OLED Microdisplays: learn more and find a supplier!

The Korean Government is launching a new ecosystem technology challenge project, with an aim to advance the use of perovskite materials in the microdisplay industry, mostly for OLED and LCD displays.

The project is led by SN Display, and include a wide range of companies and organization, including Aurum Material, Toprun Material Solution, Alpha Plus, Seoul National University, Korea University, and KAIST. Samsung Display will provide technical verification support.

Taiwan-based OLED microdisplay developer INT-Tech announced that it has developed a native RGB (direct-emission) full-color OLED microdisplay, that achieves up to 150,000 nits of brightness, breaking its own record of a 100,000 nits microdisplay unveiled in December 2025.

The company demonstrated two panels that achieve this high brightness: 0.39" XGA and 0.25" VGA. You can find more information about these displays here.

In 2024, US-based microdisplay developer Kopin Corporation spun-off its consumer OLED business unit to Lightning Silicon Technology, which also licensed Kopin's OLED technology. 

Kopin held a 20% stake at LST, and today the company announced that it has sold all of its shares back to LST, for only $2.

Samsung Display is showing its latest OLED microdisplays at AWE USA 2026, including a 40,000 nits 1.3" direct-emission OLED microdisplay, that the company refers to as RGB OLEDoS. This it the brightest OLED microdisplay demonstrated by SDC to date, and one of the brightest OLEDs ever developed (second only to INT Tech's displays).

SDC's previous highest-brightness OLED microdisplay prototype achieved 20,000 nits back in May 2025, so it is great to see the company doubling the brightness in one year. We do not know how close Samsung is to actually producing such high-brightness OLED microdisplays, but just yesterday we reported that the company is planning to build an RGB OLEDoS production line, that should achieve mass production in 2028.

In November 2025, we reported that Samsung Display has finally started to produce OLED microdisplays, and Samsung Electronics will add SDC as its second microdisplay supplier for the Galaxy XR.

SDC's current OLED capacity is rather limited, and it produces WOLED-CF microdisplays. It is now reported that SDC is starting to look into direct-emission OLED microdisplay production, and has initiated talks with equipment suppliers. The displays will also support a multi-stack (tandem) architecture. Samsung is aiming to target the high-end market segment.

Guangzhou O-vision (Aoshi) Technology has successfully concluded its Series-B funding round, raising over 100 million RMB (about $14.7 million USD). The company plans to use the funds mostly towards the construction of its 12-inch K2 OLED microdisplay fab.

Aoshi has previously concluded its seed and Series-A funding round, which together raised over 150 million Yuan (over $22 million USD). 

China-based display driver IC designer Viewtrix Technology is set to IPO at the Hong Kong stock exchange (Main Board), on May 27. The company will trade with the ticker 3310.HK.

Viewtrix (also known as Yunyinggu Technology), plans to offer 52,9 million shares, with an initial price of 20.8 HKD. Viewtrix hopes to raise around 997 million HGD (or $127 million USD) from the IPO.

US-based microdisplay developer Kopin Corporation announced that it has decided to build a full-scale OLED microdisplay production line, at the company's Westborough, Massachusetts headquarters.

Kopin says it purchased a state of the art OLED deposition system and all related equipment that is required for the new production line. When this line comes online, Kopin will be the second OLED microdisplay maker in the US together with Samsung's eMagin.

The pursuit of the ideal AR/VR microdisplay has become one of the most complex engineering challenges in our industry, with massive investments and the trajectory of spatial computing at stake. At its core lies a deceptively simple problem: how to produce red, green, and blue light from pixels 50 times smaller than a strand of human hair—without compromising efficiency, color accuracy, or the ability to manufacture at scale for mass adoption.

While many in the industry continue to wrestle with this challenge, evidence suggests that Si2OLED technology provides a compelling solution. To appreciate the significance of this approach, it is important to examine the prevailing methods in the market—and understand where they fall short.

Today’s leading commercial OLEDoS microdisplays largely rely on a white OLED combined with color filters (W-OLED + CF). In this setup, a white light source illuminates all pixels, and filters selectively pass red, green, or blue light to form images. This is the same architecture used in displays from companies like Sony, including those found in devices such as Apple Vision Pro. While functional, this design suffers from a fundamental limitation: color filters inherently waste light. Only about 25%  of the emitted light contributes to the final image, while the rest is absorbed. This inefficiency forces higher driving currents to achieve acceptable brightness, increasing power consumption, accelerating material degradation, and ultimately reducing device lifespan. In addition, in order to reach the required brightness levels, WOLED+CF architectures require the use of stacked, so-called tandem OLED devices which require a high operating voltage of around 12V which puts severe constraints on the CMOS backplane technology.
