The Position
What an OEM partner is actually buying.
A hardware-level circadian platform built on Nobel-laureate LED science, deep IP, and drop-in LCD integration. Aligned with the standards the category is moving toward.
01 / Differentiated
Spectral control at the LED layer, not at the panel. Two spectrally-engineered backlights binned on chromaticity, melanopic DER, and forward voltage. The circadian signal becomes a lot-controlled product specification, not a marketing claim or a software toggle.
02 / Defensible
500+ patent portfolio owned by Korrus across circadian lighting and display, including the Soraa IP portfolio. Soraa was co-founded by Nobel laureate Dr. Shuji Nakamura, whose foundational gallium-nitride work established the platform Korrus now owns and extends. Korrus, Inc. is a subsidiary of Ecosense Lighting.
03 / Drop-in
Standard LCD panel, unchanged. Same supply chain, same manufacturing process, same cost structure. The circadian capability lives entirely in the backlight. No new cell, polarizer, or driver IC. Designed to meet TÜV Rheinland Circadian Friendly criteria.
04 / Tailwind
CIE S 026/E:2018 is the metrology framework. Brown et al. 2022 set the indoor exposure thresholds. WELL Feature L06 makes circadian signal a credentialed building requirement. The regulatory direction is set; Korrus aligns with it.
One Display · All Day · All Night
Built for the way you actually use displays
Work, watch, read, play. Whatever you’re doing, the display tunes its biological signal to the time of day. The picture never changes. Your body knows the difference.
07:00
MAX MELANOPIC
Morning focus
Work begins. The display delivers a bright, melanopic-rich spectrum that primes your circadian system for the day.
13:00
MAX MELANOPIC
Peak alertness
Midday focus, video calls, anything cognitively demanding. Spectral content supports sustained attention.
20:00
MIN MELANOPIC
Movie night, beautiful image
D65 white point and full sRGB gamut preserved. The cinematic picture is uncompromised. The melanopic signal is not.
23:00
MIN MELANOPIC
Late reading
E-reader, laptop, phone. The biological signal is quiet. Melatonin is allowed to rise. Sleep is not delayed.
The Biology
Your body has a built-in light sensor. And it’s always listening.
Intrinsically photosensitive retinal ganglion cells (ipRGCs) detect light to regulate your circadian rhythm, independent of vision. They respond to specific wavelengths that conventional displays emit continuously, around the clock.
The Pivot
Korrus displays speak directly to this system. The right biological signal at the right time.
The Mechanism
Same screen. Same colors. Different biological signal.
The picture you see never changes. The spectral signal underneath it does.
01 / Same screen
Standard LCD panel. Drop-in compatible with the existing display supply chain.
02 / Same colors
D65 white point and full sRGB gamut. No amber tint. No visible color shift between day and night.
03 / Different signal
Day delivers a melanopic-rich spectrum. Night delivers a melanopic-quiet one. The biological message changes. Your image does not.
