RLCD or TLCD. Choose with confidence.

Two architectures, two duty cycles. RLCD turns ambient light into a sub-milliwatt image. TLCD blends reflection and backlight to span every lux. Here is the decision, mapped across power, color, temperature and cost.

Quick decision · 30-second read

Which one answers your program.

Two production-grade paths. Pick the column that matches your operating environment.

RLC · Reflective
Rec · fit

Choose RLCD for daylight and microwatts.

  • Zero-backlight, ambient-driven imaging
  • Solar and coin-cell power budgets
  • Extreme outdoor, off-grid deployments
  • Bistable segment / graphic refresh classes
TLC · Transflective
Rec · fit

Choose TLCD when the shift never ends.

  • 24 / 7 continuous duty cycles
  • Seamless sun-to-darkness legibility
  • Full-color, wide-gamut interfaces
  • Ambient-sensor driven backlight blend

Tradeoffs · Radical transparency

Boundaries, not hidden risks.

Every architecture has limits. We publish ours before your design review finds them mid-integration.

RLC · Constraints
  • Zero-ambient environments
    Rooms with no light produce no image. Requires an optional frontlight variant to remain legible.
  • Wide-gamut color work
    Color coverage tops out below full sRGB. Not the target for HDR or color-critical retouch.
  • 60 fps full-motion video
    Optimized for UI and telemetry refresh, not continuous motion pipelines.
TLC · Constraints
  • Sub-mW power budgets
    Backlight draws power in darkness. Not a coin-cell architecture for multi-year deployments.
  • Ultra-thin bezel targets
    Edge-lit stack adds ≈1.5 mm Z-height. Not for sub-3 mm wearable form factors.
  • Cost-sensitive segment BOM
    Transflector + backlight carries a higher BOM than a pure RLCD segment module.
