Revealing OLED Architecture Through Semiconductor Reverse Engineering
Overview
Lumenci supported litigation counsel in a patent infringement matter involving advanced OLED display technologies in two prominent smartphone devices. Through semiconductor reverse engineering, structural characterization, and detailed claim charting across more than 15 patents, Lumenci uncovered critical technical evidence and developed multiple infringement theories aligned with the patented innovations.
Client Challenge
The client required reverse engineering for patent infringement analysis in highly complex OLED display systems.
Accused products incorporated highly integrated OLED display architectures with limited public technical disclosures
Critical functional elements embedded within complex multi-layer display stacks
Under-display camera (UDC) region introduced additional structural and optical complexity
Key circuit structures inaccessible without advanced destructive reverse engineering
No direct documentation linking internal device structures to asserted patent claims
Need to establish clear infringement theories across multiple patents and subsystems
How Lumenci Helped
Lumenci deployed advanced semiconductor reverse engineering techniques to uncover internal OLED display structures and correlate them with the asserted patents.
Reverse engineered 14 devices across 20 patents with a repeatable ~2-week product turnaround
Conducted cross-sectioning, delayering, and imaging to characterize internal structures and materials
Extracted pixel, driver, and UDC circuit architectures while tracing signal paths and analyzing optical/material properties using spectroscopy and SEM/EDS.
Developed full claim charts and multiple infringement theories supported by physical evidence
Performed complete device teardown and advanced reverse engineering of accused OLED displays
Achievements for the Client
- Completed reverse engineering of 14 devices and 20 patents at scale without sacrificing analytical depth
- Mapped pixel, driver, and UDC architectures to asserted patent claims
- Established multiple infringement theories supported by physical evidence
- Delivered comprehensive claim charts strengthening litigation strategy
