H6 Backplane Bottlenecks, H7 Schedule Revisions, and Changsha R&D Funding Define the Conditions for Entry into Large-Area OLED
HKC’s OLED business has entered a phase of adjusting the timing and direction of mass-production investment. The Shenzhen H6 plant is shipping small quantities of smartphone OLED panels, building experience in product development and customer qualification. Meanwhile, the schedule and process approach for the new Gen 6 OLED investment at Mianyang H7 have been revised repeatedly. The H8 project, which envisages a 50K-per-month White OLED (WOLED) line on a site adjacent to Changsha H5, has also been confirmed to be under review.
H6 is an operating low-volume production site, H7 combines relocated LCD equipment with new OLED investment, and H8 remains an internal proposal. In its September investor relations (IR) activity report, HKC stated that its OLED business remains focused on R&D and that industrialization would proceed according to technological maturity and market demand. The company appears to be reassessing the sequence of mass-production investments and its target markets while continuing low-volume production and R&D at H6.
Changsha OLED R&D Funding Plan Takes Shape
HKC operates four Gen 8.6 LCD lines at Chongqing H1, Chuzhou H2, Mianyang H4, and Changsha H5. Following its listing in June 2026, the company secured funding for OLED technology development. According to its October 13 disclosure, gross IPO proceeds totaled RMB 8.493 billion, with net proceeds of RMB 8.187 billion after issuance expenses. The disclosure also outlined a plan to lend up to RMB 2.5 billion to Changsha HKC for the ‘Changsha New OLED R&D Upgrade Project.’ Funds will be disbursed in installments according to project needs. With this funding mechanism in place, Changsha is increasingly likely to become a central base for OLED technology and process development.
Both the proposed H8 site and the disclosed OLED R&D base are located in Changsha. If H8 proceeds as currently proposed, it could benefit from process transfer, workforce deployment, and shared infrastructure.
H6: Backplane Supply Is the Key Variable for Output Expansion
H6 houses Royole’s former Gen 5.5 AMOLED equipment. At its September IR meeting, HKC stated that product development and pilot production were underway at H6 and that small-scale production and shipments had begun. The site has accumulated hands-on experience in linking OLED design, process conditions, and customer qualification to actual products.
H6 Equipment Configuration and Expansion Constraints
| Category | Equipment and Process Configuration | Business Implications |
| H6 PH1 Former Royole Equipment |
Backplane (BP) substrate: 1,300 × 1,500 mm, 4K/month. Deposition uses quarter-cut 650 × 750 mm glass. Hybrid structure combining a glass substrate and thin-film encapsulation. | Base line providing operating experience. BP input capacity sets a benchmark for downstream expansion. |
| H6 PH2 Used Deposition Equipment |
Uses second-hand Sharp Gen 4.5 deposition equipment. Deposition area: 730 × 920 mm. No separate matching BP equipment has been secured. | Finished-panel output depends on externally sourced BPs and process compatibility. |
| Supporting Processes and R&D Equipment | One Kateeva inkjet system and a 200 × 200 mm R&D line. Touch processing is outsourced because there is no TSP process. | Integration of encapsulation, product structure, and outsourced touch processing affects module-production stability. |
| Relocation and Setup | Considering turnkey outsourcing of dismantling, relocation, and installation. Candidates: Siyue, Xinyihua, Wuhan Jingce. |
Vendor selection and division of responsibilities will affect installation timing and restart stability. |
H6 PH2 is being reviewed on the assumption that deposition equipment will be added while BPs are supplied from another site. Actual output may depend on BP supply volume, cutting dimensions, product design, and process compatibility.
H7: LCD Equipment Transfer and Delays in OLED Investment
H7 is understood to be proceeding under an existing corporate entity at a site adjacent to Mianyang H4. H7 PH1 is a proposed 60K-per-month line using relocated second-hand Gen 6 LTPS LCD equipment from JDI, while H7 PH2 represents a new Gen 6 OLED investment. DMS announced that it signed an equipment supply contract worth approximately KRW 41.3 billion with HKC on July 6, 2026, with the equipment to be installed at Mianyang H7. Orders for the H7 PH2 OLED deposition line have yet to be determined.
H7 Initial Plan and Progress as of October 2026
| Category | LCD and BP, H7 PH1 | OLED, H7 PH2 |
| Initial Plan | JDI line dismantling in October 2025. LCD and OLED BP light-up in November 2026. OLED BP supply to H6 from November 2027. | eLEAP: 32K/month (8K + 24K). Deposition tools scheduled for March 2027, mass production for June 2028. |
| As of October 2026 | Arrival of used equipment has begun, but setup is reportedly delayed by difficulties coordinating relocation and installation. | Year-end ordering remains uncertain. Prolonged project review could lead to cancellation of the Gen 6 OLED investment. |
In its September IR report, HKC explained that pressure on smartphone demand from rising memory prices and other factors is also affecting the small OLED market. With limited visibility into pricing and volumes, the burden of initial yield losses could be greater for a late entrant. HKC is therefore expected to reconsider its target customers and product mix while adjusting order timing and investment plans. H7 PH2 is planned to adopt JDI’s eLeap technology, making yield attainment with the new process a major factor in the start of mass production.
H6’s BP procurement plan is linked to production readiness at H7 PH1. The original plan called for H7 PH1 to supply OLED BPs to H6. Even if the H7 PH2 OLED investment is canceled, an H6 supply route could remain if H7 PH1’s BP production and qualification plans continue. Conversely, delays in H7 PH1 setup or BP process conversion could limit the benefits of expanding H6 PH2. BP production readiness and supply qualification at H7 PH1 therefore appear likely to be key variables for increasing shipments from H6.
H8 WOLED: An Option to Leverage Existing Customers and Process Capabilities
H8 is a proposal to build a 50K-per-month WOLED line on a site adjacent to Changsha H5. The substrate generation, phased investment cost, and mass-production schedule have not yet been determined. Compared with H7’s small- and medium-size OLED investment, the plan suggests an expansion into large-area OLED, drawing on HKC’s existing LCD customer base in TVs and monitors and its large-substrate process capabilities.
WOLED uses a stacked emission structure that produces white light over a large area, with color generated through color filters. LCD manufacturers experienced in Oxide TFT and color-filter processes may be able to leverage existing expertise. However, because OLED is current-driven, TFT characteristics optimized for LCD cannot be directly applied to OLED, and bringing products into mass production will require considerable time. HKC’s 2026 interim report reported mass production of LCD products using its proprietary HMO (high-mobility oxide) technology and identified the potential to extend the technology to OLED backplanes.
H8 Existing Business Capabilities and Mass-Production Validation Tasks
| Area | Existing Capabilities | Items to Verify Before Mass-Production Investment |
| Backplane | Large-area LCD production and experience with Oxide and HMO technologies | Device stability for OLED current driving, compensation circuits, uniformity, and long-term reliability. |
| Emission and Deposition | Large-substrate handling and OLED process experience at H6 | WOLED stack structure, deposition uniformity, material combinations, lifetime, and process throughput. |
| Color Filter and Encapsulation | Potential use of LCD color-filter processes and infrastructure | OLED-specific optical design and filter properties, low-defect encapsulation, contamination control, and scope for equipment reuse. |
| Customers and Supply Chain | TV and monitor customers and experience operating in-house brands | External customer qualification and purchase volumes, key equipment acceptance criteria, materials sourcing, and required technology licenses. |
Integration with HKC’s existing finished-product business is also possible. HKC operates the HKC, ANTGAMER, and KOORUI brands, and its official product site lists the OG27QK, a 2K 240Hz OLED monitor. OLED monitor panels are currently sourced externally. In-house panels could support vertical integration from product planning through modules to finished products, while the company’s own brands could serve as initial channels for product validation.
The actual shipment potential of a 50K-per-month line depends on substrate generation, panel yield per substrate, production yield, and utilization. In-house brands could support initial product qualification and shipments, but purchase commitments from external TV and monitor customers would also likely be needed to sustain stable line utilization.
Competing products are also improving. LG Display is refining its emission structure by applying Primary RGB Tandem 2.0 to its 2026 Tandem WOLED. H8’s competitiveness will depend on how it balances the brightness, color characteristics, lifetime, and price required by customers. Qualification as an additional source for product segments where these requirements can be met could provide one route into the market.
Funding and Capital Deployment Pace for OLED and Semiconductor Businesses
HKC has secured investment funding through IPO proceeds and operating cash flow. Its 2026 interim report showed higher revenue and lower net profit, alongside improved cash flow from operating activities. Expected returns from new OLED investment and funding needs in other businesses are likely to influence future investment priorities and the pace of capital deployment.
HKC Investment Capacity and Financial Constraints
| Item | H1 2026 or June 30 | Key Changes and Implications |
| Revenue / Net Profit Attributable to Owners | RMB 20.516 bn / RMB 1.857 bn | Year-on-year changes of +7.99% and −14.07%, respectively. Revenue growth accompanied by weaker profitability. |
| Operating Cash Flow | RMB 5.041 bn | Up 24.35% year on year. Internal investment funding from operations is maintained. |
| Cash and Monetary Assets / Restricted Portion | RMB 46.609 bn / RMB 23.490 bn | Includes time deposits, pledged assets, and guarantee deposits. Funds available for investment depend on restrictions. |
| Total Liabilities | RMB 75.076 bn | Consolidated liabilities include recognized obligations to acquire equity interests in subsidiaries. |

In a July disclosure, HKC announced that it would establish a wholly owned subsidiary with registered capital of RMB 4 billion for advanced packaging and testing in Shaoxing, Zhejiang Province. Capital will be contributed from internal funds over two to three years. Phase 1 targets 12-inch hybrid-chip packaging and testing, with a planned throughput of 20 million chips per month at full capacity.
According to the interim report, cumulative investment in the Chengdu project reached approximately RMB 2.6 billion at the end of June, representing 44.01% progress. Funds had been allocated to equipment and real estate. At its September IR meeting, HKC also described the Chengdu and Shaoxing businesses as advanced packaging and testing projects. Semiconductor investments already underway are likely to affect not only funding but also the allocation of equipment procurement, personnel, and management resources.
A possible plan to produce 12-inch, 20nm-class DRAM at the Gaozhen (Jinsemi) pilot plant in Chengdu was also identified. It involves adding second-hand equipment and reconfiguring the line, targeting a restart by the end of 2026.
IPO funds allocated to Changsha OLED have designated uses, while capital for Shaoxing will be contributed from internal funds in stages. HKC appears to be maintaining cash generation from LCD, continuing OLED R&D, and adjusting the sequence of major mass-production investments as it evaluates customer commitments and commercial feasibility.
Investment Stages and Equipment Order Outlook by Project
HKC’s equipment needs can be divided into H7 LCD relocation and modification, H6 process upgrades, Changsha OLED R&D, and future H8 mass-production facilities. Each involves different equipment and procurement schedules. R&D equipment may be ordered first; the timing and overall scale of orders for a 50K-per-month production line are likely to become clearer only after a specific investment plan is finalized.
Key Items to Monitor by Project
| Project | Key Items to Verify | Business Implications |
| H6 | Approval of external BP supply, installation of H6 PH2 deposition equipment, and repeated-production results | Potential increase in actual panel shipments following deposition-capacity upgrades. |
| H7 LCD / BP | Completion of relocation, stabilization of TFT processes, and specifications and qualification of OLED BPs for H6 | LCD restart timing and potential to supply OLED BPs to H6. |
| H7 OLED | Finalization of technology approach, deposition-tool orders, investment cost, and equipment arrival schedule | Whether new OLED capital investment will materialize and its implementation schedule. |
| H8 | Government agreements, project filing (备案) and environmental impact assessment, substrate generation, funding, and deposition-tool orders | Clarification of whether mass-production investment will proceed and projected capacity. Subsequent qualification and customer orders will affect utilization. |
If H8 proceeds with WOLED, new opportunities could emerge in large-area deposition, encapsulation, inspection, process automation, and emissive materials. The actual scope of new equipment orders will depend on how much of the existing TFT, color-filter, and other infrastructure can be reused. For Korean equipment and material suppliers, WOLED mass-production experience could be an advantage, while price competition with Chinese suppliers, local support, technology licenses, and customer acceptance requirements will also affect order prospects.
The impact on LG Display will depend on H8’s progress toward mass production and customer qualification. If HKC passes qualification by major customers and establishes a record of stable, good-quality supply, buyers could gain another WOLED procurement option. This may alter customers’ multisourcing strategies and price negotiation dynamics.
HKC appears to be continuing H6’s low-volume production and Changsha R&D while considering OLED mass-production investments linked to its existing TV and monitor businesses. The execution and results of Changsha R&D, BP supply readiness at H7 PH1, and further definition of the H8 investment plan will be key variables in assessing future investment scale and timing.
