Whether you'veadvancing next-generation display technology, supporting our customers, or driving business operations,you'llhave the opportunity to make a meaningful impact on products used by millions of people around the world.

Ifyou'repassionate about innovation and want to help shape the future of display technology,we'dlove to hear from you.

THE ROLE

E Ink isseekingan experienced, deeply curious engineer or applied physicist to investigate how active-matrix backplane design, electrical behavior, and modes of operation interact with electrophoretic display materials and drive schemes.

This position will join a multidisciplinary research team focused on advancing the fundamental understanding of electrophoretic display systems and translating that understanding into improved waveforms, display architectures, test methods, and product performance. The successful candidate will study the complete electrical and electro-optical system—from individual pixel circuits and backplane structures through panel-level addressing and optical response—toidentifymechanisms that affect image quality, uniformity, power consumption, reliability, and lifetime.

This is a hands-on research role combining electrical measurement, display characterization, physical modeling, experimental design, and close collaboration with waveform, materials, backplane, controller, and product-development teams.

ESSENTIAL DUTIES AND RESPONSIBILITIES

The essential duties and responsibilities of this position include, but are not limited to, the following:

• Initiate, lead, and execute fundamental research into interactions among active-matrix backplanes, electrophoretic materials, drive electronics, and waveform operation.
• Investigate how pixel-circuit and backplane characteristics—including TFT behavior, storage capacitance, parasitic resistance and capacitance, leakage, charge injection, feed through, voltage retention, RC settling, device variation, hysteresis, and bias stress—affect display response.
• Study the impact of backplaneoperatingconditions and addressing modes, including gate and source timing, line and frame timing, common-electrode behavior, hold and floating states, partial updates, power transitions, and nonideal or interrupted update sequences.
• Determine how electrical effects couple to particle motion, charge accumulation, electro-optical memory, residual voltage, optical state accuracy, ghosting, crosstalk, uniformity, color performance, and long-term display stability.
• Design controlled experiments and specialized test structures that isolatebackplane, drive-electronics,waveform, and material contributions toobserveddisplay behavior.
• Develop electrical, circuit, statistical, ormultiphysicsmodels that…
