Tiled / Modular Micro-LED Display Patent Snapshot 2026
With 12 patent families in scope, tiled and modular Micro-LED display patenting remains a concentrated, early-stage niche: the top five filers among the largest filers hold 75% of that group’s combined output, led by Shenzhen China Star Optoelectronics. Annual filing volume has eased back from its shared peaks in 2019 and 2021, and the corpus is dominated by core semiconductor device and display-circuit branches with limited activity in adjacent areas.
A small, concentrated field with a clear first-mover in China Star Optoelectronics
Shenzhen. China Star Optoelectronics (CSOT) leads the applicant ranking with 4 patent families, giving it a commanding share relative to all other filers, each of whom holds 2 or fewer patent families.
The top five filers — CSOT, ELUX Inc., Meta Platforms Technologies, AU Optronics, and LG Display — account for 75% of the ranked applicants visible in this query’ combined total, indicating a tight concentration tier with no meaningful second pack.

CSOT’s lead position, grounded in semiconductor device integration (H01L 27 and H01L 33), suggests that vertically integrated panel makers hold the strongest structural advantage in this niche today; smaller or platform-focused entrants such as VueReal and Meta Platforms Technologies have staked early claims but have not yet closed the gap.
Patent publication typically lags filing by 18–24 months, so activity in 2024–2025 is likely under-represented in the current corpus. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing activity peaked in 2019 and 2021; semiconductor devices dominate the technology mix
Two charts below capture the temporal cadence of filing and the technology branch breakdown across the 12 patent families in scope.
Annual filing trend
Filings emerged in 2019 (3 families), dipped to zero in 2020, recovered to a matching peak of 3 in 2021, then trended down to 2 per year in 2022–2023 and 1 in 2024. The most recent years (2024–2026) are subject to publication lag and likely under-represent true filing activity.

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Shenzhen China Star Optoelectronics (CSOT)
CSOT holds 4 patent families — the largest portfolio in scope — concentrated in H01L 27 (semiconductor arrays) and H01L 33 (LED dies), indicating a vertically integrated approach spanning die design through panel integration. Momentum data marks CSOT as a new entrant in the recent filing window, suggesting its activity in this specific niche is still in an early accumulation phase despite its overall scale.
patent families: 4ELUX Inc.
ELUX Inc. holds 2 patent families, with technology focus spread across H01L 25 (multi-component semiconductor devices), H01L 33 (LED dies), and H01L 27 (semiconductor arrays), reflecting a broader device-stack perspective than CSOT’s more array-centric position. Like CSOT, ELUX Inc. is flagged as a new entrant in recent filings, indicating that both leaders are still establishing their positions in tiled Micro-LED specifically.
patent families: 2Frequently asked questions
The current corpus contains 12 patent families in scope, spread across eight distinct applicants, indicating this remains a very early-stage and specialized niche within the broader Micro-LED display field.
Shenzhen China Star Optoelectronics (CSOT) leads with 4 patent families, the largest single portfolio in scope. ELUX Inc. is the nearest challenger with 2 patent families; all other applicants hold 1 family each.
Filings first appeared in 2019 (3 families), peaked again at 3 in 2021, then declined to 2 per year in 2022–2023 and 1 in 2024. The lifecycle is characterized as declining from its peak, though the most recent years are subject to publication lag and may under-represent actual activity.
The United States leads with 5 patent records, followed by China with 4. South Korea, Taiwan, and WIPO (PCT) each account for 1 patent record. The US-first profile reflects the presence of applicants such as Meta Platforms Technologies and ELUX Inc., while CSOT’s filings are anchored in China.
H01L · Semiconductor devices is the visible branch at 8 patent records, reflecting the core chip-integration focus. G09F · Displaying, advertising and signs (4 records) and G09G · Display control circuits (3 records) cover panel assembly and drive electronics. H10H, H10D, and H10F each hold 2 or fewer records.
No co-applicant relationships are recorded in this corpus. All eight filers appear to be developing tiled Micro-LED IP independently, with no visible joint-development agreements reflected in patent ownership at the time of this analysis.
