Monochrome Display Market for Electricity Meters Keeps Expanding: TOPTE Sets Benchmark for One‑Stop Custom LCD Solutions for Meters
Against the backdrop of global energy digitalization and widespread deployment of smart power grids, smart water, electricity and gas meters have become core terminals for energy infrastructure. Boasting four key merits — ultra‑low power consumption, ultra‑wide temperature resistance, long service life and high cost‑performance — monochrome LCDs have become the standard display solution for metering instruments of all types.
I. Global Monochrome LCD Market for Electricity Meters Expands Steadily: Sustained Demand in Both Domestic and Overseas Markets
According to the 2026 Global Monochrome LCD Industry Analysis Report, annual global demand for monochrome LCDs for smart electricity meters stands steadily at 600‑800 million pieces, making it the largest segmented application for monochrome LCDs and accounting for over 43 % of total monochrome display demand. The global smart electricity meter market reached USD 131.97 billion in 2025 and is expected to grow at over 8 % in 2026, driving growth of supporting segment‑code and dot‑matrix meter displays. Market demand falls into two clear segments:
Domestic Power‑Grid Market: Stable Large‑Volume Orders from State & Southern Grid Upgrades
China’s State Grid and China Southern Grid keep rolling out the second‑generation replacement program for smart electricity meters. National standards mandate strict requirements for meter displays: operating temperature of ‑40 ℃ ~ +85 ℃, 1000‑hour ageing test under 85 ℃ / 95 %RH, and a 16‑year service life. HTN and FSTN segment‑code panels serve as standard configurations, creating consistent demand for single‑phase and three‑phase electricity meters. The localization rate of domestic display modules has exceeded 87 %, bringing long‑term procurement dividends to large‑scale local manufacturers.
Overseas Emerging Markets: Surging Demand in India and Southeast Asia
India, Southeast Asia, the Middle East and other regions have launched national‑wide smart‑meter replacement policies. Local infrastructure operates under wide temperature and high‑humidity conditions, generating strong demand for weather‑resistant COG meter displays. Mature markets in Europe and America prefer premium high‑contrast FSTN / VA monochrome modules. This creates a dual‑track pattern: high‑volume low‑end demand in emerging markets and high‑margin premium demand in developed markets.
From an industrial‑capacity perspective, local LCD production lines in Japan, South Korea, Europe and America keep shrinking, and more than 70 % of global meter‑grade monochrome LCD capacity is located in Mainland China. While entry‑level simple segment‑code screens have low technical barriers, few manufacturers possess full‑process capabilities to produce high‑reliability custom LCD / LCM modules for electricity meters. Enterprises capable of supplying State‑Grid standard meters, IoT smart meters and overseas COG meters simultaneously enjoy strong industry moats.
II. TOPTE: Dedicated Manufacturing Base for Meter‑Grade Monochrome Displays with Dual Advantages of Capacity & Qualifications
Founded in 2015, Jiangxi Tongtai Visual Display Co,. Ltd. (TOPTE) runs 67 automated production lines with total monthly capacity exceeding 25KK. Its Class‑100 dust‑free G1 factory is dedicated to monochrome LCD manufacturing, with meter‑grade displays as a core mass‑production product, fully meeting production and delivery requirements for all categories of electricity meters.
Specialized Large‑Scale Production Lines to Guarantee Mass Delivery for Meters
Covering 18 526 m², G1 factory houses 3 front‑end glass lines, 16 pin‑assembly lines and 4 high‑precision COG bonding lines, delivering a monthly monochrome‑LCD capacity of 17.5KK.

Equipped with full‑set bonding equipment achieving COG bonding accuracy of ±5 μm, the workshop enables consistent control over meter‑module dimensions, segment patterns and optical parameters. Stable delivery is ensured in both peak and off‑peak seasons with full in‑house process control and no outsourced processing.
Rigorous Reliability Laboratory Meeting Stringent Meter‑Industry Standards
The in‑house standardized reliability laboratory is fully equipped with constant‑temperature‑humidity chambers, HAST accelerated‑aging testers, thermal‑shock testers and salt‑spray testers, which can replicate outdoor high‑temperature, cold and high‑humidity operating conditions for electricity meters. Meter‑grade products pass 1000‑hour continuous ageing tests under 85 ℃ / 95 %RH with a designed service life of 16 years, complying with the Chinese national standard GB/T 17215 for electricity meters as well as the international OIML metrology standards. The company holds four major certifications: ISO 9001, ISO 14001, ISO 45001 and EICC, qualifying for domestic grid procurement and overseas meter‑brand certification requirements.
