1615 high-brightness RGB beads: Supports single-color (red/green/blue), dual-color, or full RGB mixing—ideal for scale alerts (e.g., green for normal weight, red for over-limit).
Independent voltage control (R:1.9V, G:2.7V, B:2.7V): Ensures consistent color saturation without cross-interference.
199.0mm X 21.8mm dimensions: Fits perfectly into height scale top bars and electronic scale display panels.
Thin profile (2.2mm): Reduces scale thickness, enhancing portability for retail or healthcare scales.
2LED backlight circuit (If=15mA): Consumes 50% less power than 4LED modules, extending battery life of portable scales.
Mercury-free construction: Meets global environmental standards (RoHS, WEEE).

QYResearch data highlights strong growth in the scale display market:
Global dynamic weighing display market: 141 million (2024) to 217 million (2031), 6.5% CAGR—driven by logistics and retail.
Electronic scale digital display market: Grew from 26.7 billion (2019) to 35 billion (2024), with healthcare (height-weight scales) and e-commerce (logistics weighing) as key segments.
Asia-Pacific demand: 45% of global electronic scale sales, with China and India leading due to rising retail and healthcare infrastructure.
BM-7 optical testing: Ensures brightness consistency (±5% variation) across the long AA area (187.0mm X 21.8mm), avoiding uneven readability.
Temperature resistance (-10℃~+60℃): Works in cold storage (logistics scales) and warm retail environments.
Electronic wire interface: Simplifies soldering to scale PCBs, reducing assembly time.
Customizable length: AA area can be adjusted from 150mm to 250mm to fit different scale models.
The module’s model number is JR-SD19921ARGB2, with an electronic wire interface. It uses 1615 high-brightness tri-color (RGB) LED beads. The overall dimensions are 199.0mm X 21.8mm X 2.2mm, and the AA area size is 187.0mm X 21.8mm. Its power supply voltage varies by LED color: 1.9V for red (R), 2.7V for green (G), and 2.7V for blue (B). The brightness is 100CD/M2, and the backlight circuit includes 2 LEDs with a forward current (If) of 15mA—forward voltage (Vf) is 1.9V for red, and 2.7V for green and blue. The LED backlight has a lifespan of 50,000 hours.

Yes. The module supports software-controlled flashing (1–5Hz) for critical alerts (e.g., overweight packages in logistics).
We offer an optional IP65 waterproof coating for the LCD surface, suitable for bathroom or wet retail environments.
Standard RGB configurations (pre-set colors) ship in 7–10 days. Custom color profiles (e.g., brand-specific hues) require 12–15 days.
