Display Module Testing Patents: Who Leads, Where Gaps Are 2026
Display module testing and mura compensation patents: who holds the compensation-data claims
A tight, concentrated field. five ranked assignees account for all 14 records in scope, with the leader alone filing 6 of them. Filings peaked at 5 records in 2017 and have declined since; the 2026 figure is partial because the dataset cut-off is 2026-07-31 and publication typically lags filing by about 18 months, so recent-year counts understate actual filing activity.

Common questions on this field
Who are the leading patent holders in display module testing and mura compensation?
The ranked field in this dataset contains only five assignees, and together they account for all 14 records in scope. The single leader holds 6 of those 14 records, making it the largest holder by a clear margin, while the remaining four assignees hold smaller shares down to a single record each. This is a concentrated field rather than one with a long tail of occasional filers, so due diligence can focus on a short list of parties rather than a broad market scan.
What technology areas do mura compensation patents actually cover?
Every one of the 14 records in scope carries a G09G display-control-circuit classification, meaning the claims are almost entirely about how compensation values are generated, stored and applied at the driving-circuit level. Image-data-processing (G06T) and semiconductor-device (H01L) classifications each touch only one record apiece, so camera-side image processing and physical panel fabrication are comparatively under-represented relative to the compensation logic itself. A search focused only on G09G would still capture nearly the entire field.
Is patent filing activity in this field growing or slowing down?
Filing peaked in 2017 at 5 records and has not returned to that level since, with the most recent year showing 0 records. Growth cannot be reliably calculated for this dataset because there are fewer than four complete years once the roughly 18-month publication lag is accounted for. Readers should treat the apparent recent slowdown with caution rather than concluding the field has gone dormant, since 2025-2026 filings may simply not be published yet.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Display Module Testing and Mura Compensation covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
