In the race of display technology iteration, balancing high refresh rates with high image quality has long been a recognized industry challenge. Especially for the mature and stable a-Si technology route, breaking through the limitations imposed by material properties to boost refresh rates while ensuring uncompromised image quality has become the core solution to enhancing display technology competitiveness. Deeply rooted in the a-Si technology field, HKC has continuously driven the R&D and upgrading of high-end product technologies. By achieving two core breakthroughs to address key industry pain points, HKC has successfully commercialized the a-Si MNT QHD 400Hz technology. This achievement not only smashes inherent technical bottlenecks but also forms a strategic complement to the Oxide technology route, demonstrating the company’s strength in diversified technology layout.
Architectural and Process Innovations Enable Mass-Production-Grade Breakthroughs in a-Si QHD 400Hz
The core of this high refresh rate breakthrough lies in the dual empowerment of architectural innovation and process optimization. HKC has introduced the new PFA architecture, paired with a 6-mask process, laying a solid foundation for the implementation of ultra-high refresh rates without increasing the complexity of production processes or costs. Simultaneously, HKC optimized pixel design by adopting a proprietary structure and driving method, reducing data transmission pressure and enabling screen pixels to receive display signals faster and more comprehensively—fundamentally eliminating issues such as blurry and unstable images in high refresh rate scenarios.
In addition, HKC optimized the circuit layout of the panel. By adjusting the volume and sequence of signal transmission as well as the dimensions of core components, the company developed the optimal design solution for ultra-high refresh rates. During the design phase, HKC also calibrated the film thickness of each process layer through simulation to ensure the final image quality fully aligns with mass production standards, thus accomplishing the refresh rate breakthrough.
Vertical Domain Structure Empowers the Resolution of Synergistic Bottlenecks Between High Refresh Rates and High Definition
In the wide-view liquid crystal display mode, pixel architecture arrangements are categorized as horizontal and vertical domains. While traditional horizontal domains facilitate the achievement of high refresh rates, their inherent flaw of low pixel aperture ratio hinders the realization of high transmittance specifications. HKC has innovatively adopted a vertical domain I-HIS structure, which not only stably delivers a 400Hz high refresh rate but also increases transmittance from 2.8% to 4.6%—a remarkable growth of 64%.
This breakthrough not only resolves the core challenge of synchronously improving pixel signal reception efficiency and image quality but also endows a-Si technology with high-end 2K high-definition display capabilities, shattering the industry’s inherent perception that a-Si technology "cannot balance high refresh rates and high definition". It also provides a cost-effective technical solution for mid-to-high-end display products.
To ensure the reliability of technology commercialization, HKC has currently integrated this technology into 27-inch QHD display prototypes and conducted multi-dimensional RA verification, covering optical performance, high and low-temperature operation, and stringent serial test conditions. All items have passed successfully, reaffirming the scalability and stability of the a-Si QHD 400Hz technology and pointing the way for its iteration toward higher refresh rate scenarios and large-scale application.
Synergistic Development of Dual-Technology Layout Demonstrates the Brand’s In-Depth Technological Strategy
Currently, this technology forms a precise complement to HKC’s previously launched Oxide-based dual-mode 1080Hz display (QHD 540Hz + HD 1080Hz). The Oxide route focuses on flagship-level extreme high refresh rates, targeting niche high-end demands such as professional esports players and establishing a technological benchmark. In contrast, the a-Si route deepens its presence in the mature market track, leveraging its advantages of "high refresh rate + high definition + low cost + easy mass production" to cover the extensive mid-to-high-end markets including professional esports, design and office applications.
The parallel advancement of the two routes not only demonstrates HKC’s dual strength in both cutting-edge flagship technologies and innovations in mature technology routes but also constructs a market layout of "high-end leadership, mid-end volume expansion", further consolidating the brand’s core competitiveness. Going forward, HKC will continue to deepen its multi-technology route layout, drive the iteration of display technology toward higher levels, and lead the development of the display industry through innovation-driven growth.
