Variable Refresh Display Patents: Leaders & Filing Trends 2026
A data-backed look at variable refresh display patents: who holds the largest families, how filings have moved since 2017, and where G09G and G06F claim density leaves room to file.
Filing growth = 2021 (53 records) → 2024 (34); 2024 is the last year we treat as complete. Top-5 share = the 5 largest assignees ÷ all 1,041 records in scope (CR5), not the ranked leaders only.
What this landscape covers
Variable refresh rate display technology lets a panel change its scan frequency dynamically rather than run at a fixed rate, and the patent activity tracked here spans 1,041 published records filed between 2015 and the 2026 cut-off. The search combines title and claim matches on variable refresh terminology paired with display hardware, so the corpus captures both the panel-and-driver side of the problem and the software or GPU side that decides when a refresh should change. Publication lags filing by roughly 18 months, so the most recent filing years in any trend understate real activity.
The dataset groups filings by patent family so continuation and multi-jurisdiction filing do not inflate any one applicant's footprint, and the assignee ranking below reflects that same family count. IPC subclass shares are read against all 1,041 records, and because a single record often carries several classifications, those shares add up to more than 100% by design.

Filing trend and technology composition
Two views of the same 1,041-record corpus: how filing volume has moved year over year, and which IPC subclasses carry the claim density.
Filing trend, 2017–2026
Annual filings climbed from 32 in 2017 to a peak of 68 in 2023, then declined to 34 by 2024, a 36% drop from the 2021 level of 53. 2025 and 2026 figures are still filling in as publication catches up with filing, so they should not be read as a continued decline.
Publication lags filing by roughly 18 months, so 2025 onwards are still filling in. Growth rates on this page therefore end at 2024; running them to the last bar would understate the field.
IPC subclass composition
G09G (display control circuits) touches 46.6% of records and G06F (digital data processing) touches 32.4%, confirming that most claim activity sits on how a display timing controller or host processor manages refresh, rather than on the optical stack itself. H04N, G06T, G02B and G02F each cover a meaningfully smaller share, and G06Q and H04L sit lowest, marking the software-adjacent and transmission-adjacent edges of the field.
Shares are the percentage of the 1,041 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

US12431061B2 — Display device operated with variable refresh rate and method of driving the same
A display device includes a display panel driven by a gate driving circuit and a data driving circuit, with a timing controlling circuit that generates the gate control signal, data control signal and image data from an image signal and timing signals. The timing controller is configured to transmit those control signals and image data at a variable refresh rate, placing the inventive step in how the timing controller adapts its own signal generation and transmission cadence rather than in the panel's optical construction.Filed by LG Display, published 2025-09-30 — illustrates how current claims are being drafted around timing-controller logic rather than panel hardware.

Three findings that change where a new filing should aim, drawn directly from the ranking, the trend and the IPC composition.
A dense core, then a long tail
The leader alone accounts for 74 families and the fifth-ranked assignee still holds 27, but the ranked list runs to 100 companies — most holding only a handful of families each. That shape means the core timing-controller and driving-method claims are well staked out by a small group, while most of the ranked list is defending narrow, specific implementations.
A cooling curve after a 2023 peak
Filings rose steadily through the late 2010s, peaked at 68 in 2023, then fell to 34 by 2024 — the last year the dataset treats as complete. That drop follows several years of buildout around the core variable refresh mechanism, consistent with the claim space around timing control becoming more occupied rather than the underlying technology losing relevance.
Display-control circuitry is the crowded lane
G09G and G06F together cover the majority of records, meaning most contested claim territory concerns how the panel's control circuit or host processor decides on and executes a refresh-rate change. G02B and G02F, the optical-element and optical-modulation classes, sit at 7.9% each — comparatively open ground for anyone approaching the problem from the optics side rather than the control-logic side.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to displays & optoelectronics: variable refresh display patent landscape, with the prior art for and against each one.
Where to take this analysis
The figures above establish the shape of the field. Turning that shape into a filing or freedom-to-operate decision means going deeper on specific claims and specific gaps.
Map the white space by subclass
G06Q and H04L carry the lowest record shares in this corpus, which is worth checking against your own roadmap before assuming the space is unclaimed for the right reasons.

The ranked list covers 100 companies, and it is led by a single assignee holding 74 families, with the fifth-ranked company at 27 and the tenth at 20. Together the top five hold 19.4% of all 1,041 records in scope, which is a meaningful concentration but still leaves most of the ranking made up of companies with far smaller footprints. Anyone doing freedom-to-operate work should start with that leader's portfolio before assuming the field is fragmented.
Filings grew from 32 in 2017 to a peak of 68 in 2023, then fell to 34 by 2024, a 36% decline from the 2021 level of 53. 2024 is the most recent year the dataset treats as complete, since publication typically lags filing by around 18 months, so 2025 and 2026 figures will keep rising as more records publish. Read the recent drop as the core mechanism claims filling in, not as declining interest in the underlying technology.
G09G, display control circuits, appears on 46.6% of the 1,041 records in scope, and G06F, digital data processing, appears on 32.4%, together marking timing-controller and processor logic as the densest claim territory. H04N (pictorial communication), G06T (image processing) and the optics-focused G02B and G02F classes each cover smaller shares. Because a single record can carry several IPC codes, these shares add up to more than 100%, which is expected and reflects genuinely multi-disciplinary filings.
US12431061B2, assigned to LG Display and published 2025-09-30, claims a display device whose timing controller generates gate control signals, data control signals and image data, and transmits them at a variable refresh rate. The inventive step sits in how the timing controller adapts its own signal generation and transmission cadence, not in the physical construction of the panel or its optical stack. That framing is typical of recent filings in this corpus, where G09G-style control-circuit claims dominate over panel-hardware claims.
The IPC composition points to G06Q (business, commerce and admin data processing, 4.9% of records) and H04L (digital information transmission, 3.8%) as the least-claimed branches in this corpus, alongside the optics-focused G02B and G02F classes at 7.9% each versus G09G's 46.6%. That does not guarantee those branches are truly open — it may reflect fewer applicants approaching the problem that way — but it is a reasonable starting point for a design-around search before drafting a new application away from the crowded timing-controller lane.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
