Most common questions
RLCD (Reflective LCD) uses ambient light only — no backlight — for sub-milliwatt operation and true sunlight readability. TLCD (Transflective LCD) adds a switchable backlight for indoor and low-light legibility while retaining reflective performance outdoors. Choose RLCD for outdoor, battery-powered and always-on signage; choose TLCD when you need 24/7 legibility across lighting conditions.

SKU-level answers on sizes, interfaces, temperature and mechanicals.
Static RLCD content draws under 1 mW at the panel; refresh events consume a few mJ. A typical 4.4" segment RLCD runs 8–15 µA average on coin-cell power. Full datasheets list per-SKU active, refresh and standby figures.

Applications
Vertical fit for industrial, retail, transportation and OEM programs.
Battery-powered field instruments and always-on gauges use RLCD for sub-mW operation. Mains-powered HMIs with mixed indoor/outdoor use cases specify TLCD.

Custom Solutions
NRE, tooling, timelines and optical customization scope.
A 7-stage process: discovery → optical & mechanical feasibility (2–3 wk) → engineering samples (6–8 wk) → qualification → tooling → pilot → mass production. Typical NRE ranges from $15k for cosmetic customization to $120k for a full optical redesign.

Ordering & Quotes
Lead times, MOQs, incoterms, warranty and RMA policy.
Yes. Ready-To-Sell (RTS) SKUs ship as evaluation units within 3–5 business days from stock. Custom programs receive a bench evaluation panel after the feasibility phase.
Category
Partners
Distribution, design-house and reseller enablement.
Yes. Authorized distribution across North America, EMEA and APAC, plus a certified design-house program with shared engineering resources.
Category
Company
Manufacturing, compliance, contact and legal.
Manufacturing operates under ISO 9001:2015 with IATF 16949 in progress. Panels are RoHS and REACH compliant and CE marked. Medical and automotive programs support additional ISO 13485, IEC 60601 and AEC-Q100 qualification paths on request.
