ELECTRONIC INK & EPD (EPAPER DISPLAY MODULIE) TECHNOLOGY

E Ink Catra™ Black and White High Refresh Rate ePaper Technology

1. E Ink Catra™
  • Refresh rate:70ms~2000ms
  • Contrast Ratio: 15:1
  • Color: Black, White, 16 Gray
  • PPI:300
  • Operating temperature:-15°C~65°C

E Ink Carta™ is a microcapsule-based ePaper technology that contains millions of charged particles in black and white. It supports 16 grayscale levels from black to white,featuring fast refresh rates, excellent stability, and a wide temperature range. It is primarily used in e-readers and other high refreshrate applications

E Ink Kaleido™ High Refresh Rate Printed ePaper Technology

2. E Ink Kaleido™
2. E Ink Kaleido™-Applicantion
  • Refresh rate:70ms~2000ms
  • Contrast Ratio: 10:1
  • Color: 4096 colors (12-bit)
  • PPI:150
  • Operating temperature: -15°C~65°C

E Ink Kaleido™ prints color filters on top of 16 grayscale black and white electronic paper, on which small shaped RGB filter arrays(CFA) are printed.When a pixel beneath a red, green, or blue filter is white, the corresponding color is visible. When the pixel is black, no light reflects, making that area appear black. By combining the 16 grayscale levels with the CFA, the display can produce 16 color shades per channel, and groups of RGB dots together deliver up to 4,096 colors.

E Ink Spectra™ Color High Saturation ePaper Technology

Spectra is a multi-color, high-saturation ePaper technology designed for electronic shelf labels (ESL), signage, advertisements, and other display applications. Starting with three colors, it has evolved through four, five, and seven colors, and now offers full-color solutions.

E Ink Gallery™ High Resolution Full Color ePaper Technology

6. E Ink Gallery™
  • Refresh rate: 350ms for black and
    white, 500ms to 1500ms for color
  • Contrast Ratio: 14:1
  • Color: Full color (approximately 60,000 colors)
  • PPI:300
  • Operating temperature: 0°C~50°C

Each microcup integrates CMYW (cyan, magenta, yellow, white) particles-no color filter needed. This e-ink technology improves light efficiency and color accuracy while retaining ePaper’s zero-power static display. Designed for e-readers and digital notebooks, it delivers 300 PPI full color witth faster refresh and low-latency handwriting.

E Ink Marquee™ Extended Temperature Full Color ePaper Technology

7. E Ink Marquee ™
  • Refresh rate: 5s~7s
  • Contrast Ratio: 22:1
  • Color: Full color (Around 60,000 colors)
  • Size (inch): Outdoor large screen (55″ or larger)
  • Operating temperature:-20°C~65°C

This extended temperature full color ePaper is engineered for outdoor anddigital out of home (DOOH) signage. Its core features include direct four color particle display, 22:1 high contrast ratio, and stable operation across-20°C to 65°C without cooling systems, with zero static power consumption. It is ideal for outdoor harsh environments and programmatic advertising scenarios.

ePaper Technology VS LCD Technology

ITEM
COLOR EPAPER DISPLAY
LCD
Revelation principle
Reflective (electrophoretic particle movement), non-luminous
Backlight penetrates the liquid crystal and filter, enabling active light emission
Color gamut space
40%–50% sRGB, 6–8 primary colors, 60,000+ colors
70%–100%+ sRGB/NTSC, with millions of colors
Color model
RYB/CMY (subtractive model, light absorption, the more you mix, the darker it gets)
Color ePaper RYB-CMY
RGB (Additive Color Model, Emitted Light, Brighter the More Mixed)
LCD RGB
Contrast ratio
30:1 (Reflective, better in strong light)
1000:1 – Million:1 (Dark-field intensity, light-sensitive to reflections)
Power dissipation
Very low: Only refresh power consumption, zero static power consumption
High: The backlight remains on continuously, resulting in sustained power consumption.
Refresh speed
Millisecond (Max 14Hz)
Millisecond (60–144Hz)
Viewing angle
Around 180°, no color bias
178° (IPS), partial angle color shift / brightness reduction
High light visibility
Excellent, clear under direct sunlight
Poor, prone to reflection, unclear
Blue light / strobe
0 Blu-ray, 0 flicker, Eye-friendly
Blue light and PWM strobe are present, which may cause prolonged fatigue.

Electronic Ink Technology Feature

Electronic Paper Display uses reflected ambient light and maintalns the image with zero or ultra-low power consumption.
An ePaper module is composed of three key parts: the ePaper film (FPL), TIFT backplane, and driver IC. It works by moving charged ink particles under an electric field to form images
