What This Patent Covers

This patent protects the specific mechanisms for high-resolution, high-density, and control of multi-view video in 3D display devices. Its claims were thoroughly examined against nine prior art documents and successfully granted after a single office action, indicating a robust and clearly defined scope with low invalidation risk.

Competitive White Space

This patent primarily covers the display device and its control for high-resolution 3D. It leaves white space for developing novel 3D content creation tools, advanced haptic feedback systems, or specialized application-specific interfaces that leverage this display technology.

Economic Impact
~$1.5M/year estimated system development cost reduction per facility (est.)
estimated ROI · USD · AI analysis
ROI Calculation Logic

Conventional high-definition 3D display system development required approximately 3 years, including annual engineer labor costs of ~$1M (AI est.) (5 engineers × ~$40K/year/engineer × 50% development effort) and a total prototype cost of ~$0.5M (AI est.). By adopting this technology, the development period could be reduced to 1 year, eliminating complex control design. This could result in a first-year saving of ~$1M (AI est.) in engineer costs and ~$0.5M (AI est.) in prototype costs (representing 2 years of previous prototype expenditure), totaling ~$1.5M (AI est.) in the initial year.

Speed to Market
5× faster than in-house development
This technology's optical control algorithms, such as half-pixel shifting and optical axis shifting, are detailed in the patent specification. Drive control is also based on control signals, making software and hardware integration relatively straightforward. This could shorten development time by approximately 3.2 years compared to ground-up development. Integration into existing video display systems is also anticipated to be efficient, as key components are already well-defined.
