The global competition in the new display industry has entered a critical phase. From smartphones to smart cockpits, the rapid evolution of end-market demands is pushing mainstream display technologies toward their theoretical limits, driven by consumers' pursuit of ultimate color performance and innovative form factors. Against this backdrop, a significant challenge—and opportunity—has emerged under China's national strategy of "technological self-reliance": How can we meet the extreme demands of future displays while ensuring the autonomy of core materials?

Jinghui Zhiguang, a Chinese tech company specializing in all-inorganic halide perovskite quantum dot superlattice display materials, has transformed years of laboratory research into a breakthrough solution for the industry. With a decade of perseverance, the company has provided an innovative answer to the "bottleneck" challenges in display technology.

**A Perovskite Odyssey Toward the Photonic Era** "We stand at the final chapter of display history and the cover of the photonic era," said Professor Liu Yong, poetically describing the current technological inflection point. A doctoral advisor at Wuhan University of Technology's School of Materials Science and Engineering, Liu built his academic foundation under the guidance of Academician Zhao Dongyuan at Fudan University before furthering his studies at the Lawrence Berkeley National Laboratory under Academician Peidong Yang. His decision to return to China and commercialize his research insights has been pivotal in driving industrial transformation.

Jinghui Zhiguang's core technology—all-inorganic halide perovskite quantum dot superlattice display materials—is the key to this breakthrough. Under Academician Zhao's mentorship, the team has successfully integrated mesoporous material systems with perovskite quantum dot encapsulation, achieving a five-in-one breakthrough: all-inorganic encapsulation, surface passivation, high loading capacity, high brightness, and high stability. These advancements are supported by remarkable performance metrics: PLQY >95%, EQE >25%, and FWHM <15nm (even below 10nm in some materials).

"These benchmarks have been consistently reproduced in kilogram-scale batches and LED device modules, setting us apart not only in wet-process perovskite materials but also in the broader quantum dot and next-gen display sectors," emphasized Professor Liu.

**Redefining Display Boundaries Through Material Innovation** "Think of it as giving perovskite quantum dots a 'nano bulletproof vest'—hard yet porous silica that blocks moisture, oxygen, heat, and UV rays," explained Fan Rongwei, co-founder and CEO of Jinghui Zhiguang, using a vivid analogy. "Meanwhile, we structure perovskites into atomically thin 'layered cakes,' where one layer emits light and another tunes energy bands—like building highways for electrons to travel smoothly, producing brighter, purer, and more energy-efficient light."

With nearly a decade of entrepreneurial experience, Fan plays a crucial role in bridging lab innovations with market applications. The company has developed four product lines centered on perovskite superlattices: quantum dot powders, high-quality quantum dot inks, flexible display luminescent materials, and smart display modules. These cater to diverse applications, from QD-LCDs and QD-OLEDs to AR/VR and smart cockpits, offering superior color purity, efficiency, and wide color gamut.

**Collaborating for a Sustainable Display Ecosystem** Jinghui Zhiguang is actively partnering with upstream and downstream industry players to accelerate R&D and commercialization. Its quantum dot powders and inks have undergone batch testing with leading domestic panel manufacturers, while flexible display materials are being co-developed with smart cockpit system providers for automotive and wearable applications.

**A Vision for Global Leadership** Academician Zhao Dongyuan praised the team's "groundbreaking collective luminescence mechanism," which overcomes traditional material limitations and offers scalable solutions for OLED, QLED, and Micro-LED displays. Jinghui Zhiguang aims to establish pilot production lines within three years, achieve ¥100 million in sales within five years, and ultimately emerge as a globally competitive smart display materials brand.

"Perovskite quantum dots aren’t just materials—they’re engines that turn light into language," concluded Professor Liu. "We invite partners to join us in scripting China’s next chapter in display innovation, where light defines the future—and the future starts now."
