Meter-Grade Display Solutions
Low-power, wide-temperature LCD and LED displays for electricity meters, water meters, gas meters, and industrial measurement instruments. Built for 10+ years of unattended operation.
The Numbers That Matter in Metering
Before anything else, a meter display has to hit these four numbers. Here's what we deliver.
Reflective static display, no backlight
Single cell, unattended operation
Outdoor pits, cabinets, extreme climates
IQC → IPQC → OQC on every unit
Three Design Choices That Save the Battery
Ultra-low power isn't a single feature — it's a combination of three design decisions.
Reflective Polarizer
No backlight needed — ambient light is reflected off the rear polarizer and read by the user. The backlight, which normally draws the most current, is eliminated entirely.
Low-Power LCD Fluid
The liquid crystal fluid is selected for a low threshold voltage, so the segment can be driven at minimal voltage. This drops the per-segment current draw to the microamp range.
Static Drive Mode
Each segment is driven directly, not multiplexed. Multiplexing saves pins but costs current — static drive eliminates the duty-cycle current multiplier entirely.
Result: A static reflective segment LCD drawing <10 µA in continuous display — well within a 10-year battery budget.
Display Solutions for Metering
Three product lines that cover most smart meter and measurement applications.
FSTN Segment LCD
High-contrast, ultra-low-power segment LCD for electricity, water, gas, and heat meters. Reflective/transflective polarizer.
LED Digital Tubes
High-brightness LED digital tubes for industrial measurement instruments where daylight readability matters more than power.
Smart Meter TFT
Full-color TFT for smart meters with menu interface, historical data display, and touch input. High brightness and wide temp options.
Match Your Meter to the Right Display
Quick reference — which product line fits which meter type and power source.

| Gas Meter | Reflective FSTN + Anti-UV Polarizer | Outdoor · Wide temp · Warning icons |
| Heat / BTU Meter | Transflective FSTN Segment LCD | MWh/GJ units · M-Bus ready · Wide temp |
| Industrial Measurement | LED Digital Tube (4–6 digit) | High brightness · Wide viewing angle |
Display + Communication in One Module
Since we run PCBA assembly in-house, we can deliver a fully integrated display + MCU + communication module.
NB-IoT
Low-power wide-area network. Ideal for water/gas meters where battery life and coverage matter.
LoRa / LoRaWAN
Long-range, low-power. Common in private utility networks and industrial sub-metering.
RS-485 / Modbus
Wired industrial standard. For electricity meters and industrial measurement instruments.
M-Bus / Wireless M-Bus
European standard for utility metering. Common in heat and water meters.
Turnkey advantage: We can deliver a display + driver IC + MCU + communication module in one assembly — tested and ready to plug into your meter board.

Common Questions
Questions from metering buyers and engineers.
Can the display start reliably at -30°C?
My MCU pins are limited — can you optimize the drive scheme?
Can you reverse-engineer a display when the original supplier stopped production?
Can you deliver a display + MCU + communication module as one assembly?
