Porotech at Display Week 2024, CEO Tongtong Zhu talks Porotech's Breakthroughs, upcoming microLED

At Display Week 2024 in San Jose, Tongtong Zhu, the CEO and founder of Porotech, highlighted their advancements and innovations in augmented reality (AR) technology. Porotech, a company specializing in semiconductor and display solutions, showcased a range of products and solutions aimed at AR applications, particularly focusing on AR head-up displays (HUD) and AR glasses. Zhu emphasized their success in creating a comprehensive supply chain ecosystem that consolidates various stages of material processing and camera module assembly, ensuring the seamless production of AR devices.

One of the key innovations presented was the production of tiny 0.12-inch microdisplays suitable for lightweight AR glasses designed for consumer applications. Porotech has developed a small projector capable of providing full-color displays, further enhancing consumer-oriented AR applications. Zhu discussed the importance of providing a full solution AR value chain, which involves close collaboration with end customers to meet their specific design and product requirements. This integrated approach ensures that Porotech can leverage the entire ecosystem to deliver high-quality AR products efficiently.

Porotech's innovation extends to wafer-to-wafer bonding, which guarantees high yield and low cost for consumer applications. This process allows for the production of singulated microdisplays that are then packaged and assembled into optical systems. This one-stop-shop approach, in partnership with Foxconn Technology Group, streamlines the manufacturing process and enhances the overall efficiency of AR device production.

Zhu proudly claimed that Porotech's technology offers an extensive range of colors, covering the entire visible spectrum. Despite this capability, they still adapt to conventional RGB or RGBY benchmarks to ensure compatibility and comparability with other products on the market. The dynamic tuning technology unique to Porotech allows for on-the-fly color adjustments, enhancing the visual experience by adapting to different backgrounds without significant computational power, which also results in lower power consumption compared to other microdisplays.

The advancements in AI, particularly with technologies like GPT, have accelerated the demand for AR solutions. Zhu predicted that prototype AR glasses incorporating Porotech’s technology would be available early next year, with commercial products expected by the end of the year. At Display Week, Porotech demonstrated various AR HUD projectors for automotive applications and microdisplays for AR glasses, showcasing both monochrome and polychrome displays that cater to different platform technologies.

Porotech's adaptive TBT dynamic technology stands out as it allows users to change colors and contrast dynamically based on the background, enhancing visibility and user experience without draining the battery. Zhu emphasized that Porotech's microdisplays are at least one-third less power-hungry than competitors, thanks to their efficient on-the-fly color adjustment capability, bypassing extensive computation.

The AR market has been significantly influenced by companies like Apple, which have set high standards for user experience despite challenges with wearability and power consumption. Porotech aims to deliver lightweight, power-efficient, and affordable AR solutions that can enhance productivity without the need for cumbersome and expensive devices. Their approach focuses on balancing various factors such as color purity, resolution, and battery life to meet consumer expectations.

Finally, Zhu discussed the improvements in waveguide technology and eye-tracking systems, which are essential for enhancing AR experiences. Porotech's efforts in consolidating the supply chain and focusing on performance and cost efficiency aim to make AR technology more accessible and widely adopted. With manufacturing bases in the UK and Taiwan, Porotech is poised to bring innovative AR products to market, with samples expected in 2024 and broader availability by 2025. The company is committed to continuous improvement and collaboration with partners to advance the AR industry.
