Taiwan-based PlayNitride aims to reduce MicroLED production costs by 75% by 2030 through smaller chip designs and its proprietary high-efficiency Tantium chip architecture, positioning the technology for broader adoption across consumer electronics, automotive displays, AR devices, and optical interconnects, founder and chairman Charles Li said at South Korea's Display Business Forum 2026.
Cost reduction hinges on chip scaling and Tantium architecture
Speaking at the forum, held July 21-22, Li reviewed PlayNitride's progress since launching the world's first dedicated MicroLED mass-production line in 2019, while addressing one of the industry's biggest challenges: manufacturing cost.
Li said achieving substantial cost reductions requires two parallel advances—continued chip miniaturization and higher-yield mass transfer technology. Shrinking chip size allows significantly more dies to be produced from each wafer, potentially increasing output by up to four times and theoretically reducing material costs by roughly 75%.
However, simply making chips smaller is not enough, he said. As chip dimensions shrink, brightness and energy efficiency typically decline, creating a technical hurdle that conventional MicroLED designs struggle to overcome.
Proprietary technology targets higher efficiency
To address that challenge, PlayNitride has developed Tantium, its proprietary high-voltage, low-current MicroLED chip architecture.
Li said the technology substantially lowers the driving current required by each chip while remaining compatible with existing display panel designs, enabling manufacturers to adopt it without redesigning their current architectures.
He explained that under the conventional 2T1C pixel circuit design, more than 60% of input power is consumed by the driving thin-film transistor (TFT) rather than by the light-emitting diode itself. Reducing the current flowing through the TFT therefore delivers meaningful gains in panel-level efficiency, making Tantium a key element of PlayNitride's long-term cost and performance strategy.
Broad technology platform supports multiple applications
PlayNitride has established an integrated technology platform covering epitaxial growth, chip fabrication, mass transfer, module assembly, and optical integration.
The company also offers three display-driving platforms based on application requirements and pixel density—TFT, PCB, and silicon-based solutions. These target a broad range of products, including flexible and rollable displays, large-format tiled displays, projectors, and AR microdisplays.
Li said the company's strategy is to provide optimized technology platforms for different market segments rather than relying on a single architecture across all applications.
Wearables, transparent displays, and AR emerge as key growth markets
PlayNitride has already commercialized what it describes as the world's first MicroLED smartwatch, featuring brightness of 4,500 nits, wide viewing angles, and strong outdoor visibility. The product demonstrates the scalability of MicroLED technology from large-format televisions to compact wearable devices.
Transparent displays represent another area where the company sees strong competitive advantages. Thanks to the extremely small size of MicroLED chips, PlayNitride can produce transparent panels with 70-80% transmittance while maintaining brightness ranging from several thousand nits to more than 10,000 nits.
Li said such capabilities make the technology well-suited for automotive head-up displays, transparent smart windows, and other applications where conventional LCD technology has limitations.
AR glasses are another priority because high brightness is essential for displays operating under strong ambient light. Leveraging MicroLED's small chip size, PlayNitride has introduced a full-color microdisplay featuring 720×720 resolution, a 30-degree field of view, brightness exceeding 500 nits, and power consumption below 150mW. Li said the display ranks among the industry's smallest full-color MicroLED solutions while balancing brightness, image quality, and energy efficiency.
Optical interconnect and overseas expansion shape next growth phase
Beyond displays, Li identified optical interconnect as one of the next major opportunities for MicroLED technology, citing its advantages in bandwidth, integration flexibility, and power efficiency.
During a previous earnings call, PlayNitride disclosed a strategic partnership with Brillink, an Alchip Group affiliate, to develop optical interconnect technologies. The company expects related non-recurring engineering (NRE) revenue to begin contributing in the second half of 2026, with commercial deployment more likely around 2028.
On global expansion, Li said PlayNitride will continue strengthening its international presence while maintaining its headquarters and wafer manufacturing operations in Taiwan. In addition to expanding in the US and China, the company is planning to establish a presence in Singapore.
Looking ahead, Li said MicroLED is evolving into a platform technology extending well beyond displays. By combining application-specific technology platforms with continued advances in Tantium, PlayNitride expects to improve efficiency, lower production costs and accelerate adoption across a broader range of commercial applications.
