RGB Mini LED is attracting attention as a next-generation display technology due to its ability to separate and control colors from the backlight stage, resulting in higher color purity and reduced light loss. Its scalability to large-area, high-brightness environments is also remarkable. This technological advancement has first become visible in the ultra-large-screen TV market. HKC has proven its large-area display capabilities by supplying 100-inch and larger RGB Mini LED TV panels to the global TV brand Hisense. In particular, the RGB Mini LED panel used in Hisense’s 116-inch UX series reportedly achieves a peak brightness of approximately 8,000nits, features 3,584 local dimming zones, and achieves color reproduction performance that meets over 95% of the BT.2020 color gamut. Simultaneously achieving high brightness and color uniformity on ultra-large screens is a technically challenging task. HKC is satisfying these requirements with RGB Mini LED, establishing a unique technological edge in the ultra-large TV market.

In the monitor market, the precision control capabilities of RGB Mini LED are expected to be further highlighted. HKC plans to officially announce its next-generation premium monitor lineup based on RGB Mini LED at CES 2026, expanding its large-area TV picture quality technology to high-resolution, high-refresh-rate desktop environments. The 31.4-inch 4K RGB Mini LED monitor, the “M10 Ultra,” is expected to be unveiled at CES 2026. It features a total of 1,596 physical local dimming zones and employs cluster-based operation, individually controlling RGB elements within each zone. This RGB cluster-based control is a key factor in effectively suppressing the halo effect, a problem faced by existing Mini LED monitors. Its performance targets the premium market, with a peak brightness of approximately 1,600nits, a native refresh rate of 165Hz, and up to 330Hz in FHD mode. Color reproduction is also expected to reach 98% to 100% of the BT.2020 standard, making it ideal for gaming environments as well as video editing and professional monitors where color accuracy is crucial.

The automotive display sector is also a key area where HKC is strategically expanding its RGB Mini LED offerings. With the spread of electrification and autonomous driving technologies, in-vehicle displays are becoming larger and more multiplexed. Stable visibility even under direct sunlight and reliability over long periods of use are emerging as key requirements. HKC’s automotive display solution, utilizing RGB Mini LEDs, has reportedly achieved a power consumption reduction of approximately 20% compared to conventional methods while maintaining high brightness of over 1,000nits. In particular, in large-scale integrated display structures that integrate the cluster and CID into a single screen, RGB Mini LEDs are recognized as a technology suitable for next-generation dashboard design due to their ability to easily maintain brightness and color uniformity.

HKC is pursuing a dedicated Mini LED production base project worth approximately 9 billion yuan in Liuyang, China, with an annual production capacity of over 500 million Mini LED backlight modules. This production base integrates LED chips, backlight modules, and panel assembly into a single value chain, serving as a strategic base for simultaneously securing cost and supply stability, key challenges for RGB Mini LEDs. Furthermore, through the operation of its direct-view LED factory in Mianyang, HKC is accumulating experience in ultra-fine LED processes and laying the foundation for expansion into next-generation LED-based displays. According to Changwook Han, Executive Vice President of UBI Research, “HKC’s RGB Mini LED strategy is a strong mid- to long-term technology roadmap encompassing TVs, monitors, and automotive displays. Key to this is that it has simultaneously secured the core elements of high brightness, high color reproduction, and precision control, and is expanding these to large-area displays and high-reliability environments. With this, coupled with large-scale investments in Mini LED and M-LED production infrastructure, HKC is establishing a unique position in the next-generation LED-based display ecosystem.”

HKC Pushes OLED Expansion: Smartphone Panel Trial Production Starts, G6 eLEAP Line Planned

/in , /by

HKC, one of China’s leading display panel manufacturers, is accelerating its transition into the small- and medium-sized OLED market. Moving beyond its traditional focus on large-sized LCDs, the company is now expanding into flexible OLED panels for smartphones and IT devices, while also actively investing in next-generation maskless OLED fabrication technologies.

HKC plans to begin trial production of smartphone OLED panels at its H6 facility in July 2025. The Phase 1 line has been built using secondhand 5.5-generation equipment previously owned by Royole, and features a hybrid structure that applies flexible encapsulation on glass substrates. The TFT backplane has a monthly capacity of 4,000 substrates, and the evaporation process follows a quarter-cut method.

In Phase 2, HKC is incorporating 4.5-generation EVEN equipment transferred from Japan’s Sharp, which is expected to be restored and operational by April 2026. The company also owns a dedicated OLED R&D line, currently undergoing restoration, with completion targeted for September 2025.

Notably, HKC is planning to build a dedicated G6 (6th-generation) OLED mass production line based on eLEAP technology. While Kunshan was initially considered as the investment site, current indications suggest the project will likely shift to Mianyang in Sichuan Province, due to changing policy dynamics and stronger local government partnerships. HKC is currently seeking regulatory approval from the Chinese government for its G6 OLED line based on eLEAP technology. While FMM (Fine Metal Mask) processing is also being considered as an option, it is understood that approval for FMM is highly unlikely due to regulatory constraints. The production line is expected to incorporate secondhand equipment from Japan Display Inc. (JDI), with potential for accompanying technical support.

This strategy signals a broader shift in China’s OLED industry, moving beyond simple production scale-ups to focus on achieving global competitiveness in advanced manufacturing technologies.

A parallel effort is underway at Visionox, which is building a G8.6 OLED line (V5) in Hefei. There, the company is developing and preparing to mass-produce OLED panels using ViP (Visionox Intelligent Pixelization), a maskless pixel formation technology based on photolithography and patents from Japan’s SEL. This approach avoids the resolution and yield limitations associated with traditional FMM processes.

HKC’s eLEAP investment aligns with this broader maskless OLED trend. Developed by JDI, eLEAP technology enables precision pixel formation without metal masks, offering advantages in aperture ratio and panel longevity. HKC signed an MOU with JDI in 2023 for joint development of eLEAP-based OLEDs. Although the companies later scaled back plans for a joint OLED fab, technical collaboration is understood to be ongoing.

The parallel efforts of HKC with eLEAP and Visionox with ViP demonstrate China’s intent to lead not only in OLED manufacturing capacity, but also in core next-generation fabrication technologies. This shift underscores the nation’s strategic ambition for technological self-reliance and global leadership in OLED production—an ambition likely to reshape the future of the small- and medium-sized OLED industry.
