E Ink Marquee™ is a color electrophoretic display technology built specifically for digital out-of-home (DOOH) advertising and outdoor signage. It’s a 4-particle color system — distinct from E Ink’s other color technologies like Spectra 6 — engineered around the specific demands of large-format outdoor displays: wide temperature tolerance, energy efficiency, and enough refresh speed to support rotating advertising content, while still holding onto e-paper’s core advantages of sunlight readability and near-zero static power draw.
This guide covers how Marquee works, what its key specifications are, and where it fits relative to E Ink’s other color technologies.
How E Ink Marquee Technology Works
Like all E Ink electrophoretic displays, Marquee produces an image by moving charged pigment particles within microcapsules using an electric field, rather than emitting light through a backlight. Marquee’s color comes from a 4-particle system combining cyan, magenta, yellow, and reflected white pigments within each microcapsule — mixing these particles in different combinations (yellow with magenta, white with yellow, and so on) produces the visible color at each pixel, rather than relying on a color filter layered over a black-and-white panel.
Once an image is formed, it holds in place without continuous power, the same bistability that defines every E Ink display technology. Power is only required at the moment the display transitions to new content — which for Marquee, E Ink specifies as a 5-7 second transition time. Unlike the abrupt flash typically seen when e-paper signage refreshes, early demonstrations of Marquee showed a smoother, animated transition between frames — a deliberate design choice for content like rotating ads and campaign creative, where a jarring flash between frames would be more noticeable than in slower-updating signage.
Key Specifications
Based on E Ink’s published specifications for Marquee:
- Contrast ratio: 22:1
- Operating temperature range: -20°C to 65°C
- Transition (refresh) time: 5-7 seconds
- Panel sizes: Actively expanding, with development targeting sizes up to 75″ diagonal
That operating temperature range is a standout figure — it’s built to handle real seasonal outdoor extremes, not just moderate climates, which matters for signage that has to keep working through both summer heat and winter cold without a climate-controlled enclosure.
Why Marquee Was Built for DOOH and Outdoor Signage
Conventional LCD and LED displays used for outdoor digital signage generate significant heat, particularly at large panel sizes, which typically requires active cooling systems to keep the display operating reliably. E Ink designed Marquee’s thermal performance specifically to reduce that need for complex cooling — a meaningful cost and reliability advantage for large outdoor installations, where a cooling system is one more component that can fail in the field.
Marquee’s 5-7 second transition time also reflects a deliberate design choice for DOOH: fast enough to support page-based content rotation — swapping between ads, schedules, or campaign creative — without needing the frame-by-frame refresh speed that video requires. E Ink describes this as enabling integration with brand activations and programmatic advertising campaigns, positioning Marquee for dynamic outdoor advertising rather than fully static signage alone.
E Ink Marquee vs. Other E Ink Color Technologies
Marquee joins a lineup of E Ink color technologies that includes Gallery 3, Kaleido 3, and Spectra 6 — each built for a different category of device. Interestingly, Marquee’s underlying particle approach has more in common with Gallery 3 than with Spectra 6: both use a direct multi-pigment (CMYW) system built into each microcapsule, rather than a color filter layered over a monochrome panel. But where Gallery 3 was built for handheld reading devices, Marquee has been re-engineered around outdoor DOOH requirements — a far wider operating temperature range, faster transitions, and a smoother frame-to-frame transition suited to rotating advertising content.
Spectra 6 remains E Ink’s other technology purpose-built for commercial signage, and the two are optimized for different priorities. Spectra 6 is tuned for color fidelity and typically holds a wider color gamut on signage that changes only a handful of times a day, while Marquee trades some of that color depth for a notably wider temperature range and a significantly faster transition — helpful for DOOH content that rotates more frequently than a typical static price display or storefront sign.

Where E Ink Marquee Is Used
Marquee’s combination of outdoor durability, color, and low power consumption fits a specific set of applications:
- Digital out-of-home (DOOH) advertising — billboards and large-format displays showing rotating ad campaigns
- Transit and transportation signage — schedule and wayfinding displays exposed to outdoor conditions
- Outdoor retail signage — storefront and large-format promotional displays
- Wayfinding and directional signage — for university campuses, healthcare facilities, corporate campuses, and public spaces
- Interactive street furniture — bus shelters, kiosks, and public displays integrated into outdoor infrastructure
MyGica’s EPC5500 is a 55″ outdoor color display built on E Ink Marquee technology, designed for DOOH advertising, transit networks, and outdoor retail deployments.
Frequently Asked Questions
What colors does E Ink Marquee use to produce its images? Marquee uses a 4-particle system combining cyan, magenta, yellow, and reflected white pigments within each microcapsule. Mixing these particles in different combinations produces the visible color at each pixel, similar in principle to E Ink’s Gallery 3 technology, though Marquee is engineered for outdoor DOOH use rather than handheld reading devices.
Is E Ink Marquee the same as E Ink Spectra 6? No. Both are E Ink color electrophoretic technologies, but Marquee is a distinct 4-particle color system built specifically for DOOH and outdoor signage, with a wider operating temperature range and faster transition time than Spectra 6, which is optimized instead for color fidelity on signage that updates infrequently.
Can E Ink Marquee display video? No. Marquee’s 5-7 second transition time supports rotating content like ad campaigns and scheduled updates, but it isn’t built for video or animation, which require continuous frame-by-frame refresh.
Why does E Ink Marquee need less cooling than LCD or LED displays? Marquee’s thermal performance was specifically engineered to operate reliably across a wide temperature range (-20°C to 65°C) without the active cooling systems that conventional LCD and LED displays typically require at large outdoor sizes, reducing both installation complexity and points of potential failure.
What sizes is E Ink Marquee available in? E Ink has stated ongoing development toward panel sizes as large as 75″ diagonal. MyGica currently offers a 55″ display, the EPC5500, built on Marquee technology.
