STONE Technology

What STONE Technology does

STONE Technology (Beijing STONE EN Technology Co., Ltd. / 北京斯通恩科技有限公司) is a privately held Chinese manufacturer founded in 2010 that specializes in intelligent TFT LCD display modules for industrial human-machine interface (HMI) applications. Its core product is an all-in-one display module that integrates a CPU (1GHz Cortex A8 in the V-Series, or Cortex M4 200MHz in earlier STV variants), Flash memory (256MB standard, expandable to 1–2GB), and resistive or capacitive touchscreen into a single unit, with screen sizes ranging from 3.5" to 15.1". The modules are controlled by any external MCU (8051, AVR, MSP430, STM32, MC9S12, Arduino) over a UART serial interface using a simple JSON command set, eliminating the need for host-side video signal generation. Supporting software is the free, cross-platform STONE Designer GUI tool for Windows, macOS, and Linux.

The company sells across five product series — Industrial (STWI), Advanced (STWA), Civil (STWC), Economics, and Control Board — plus OEM customization services (display size, logo, firmware, mechanical, optical bonding) with NRE fees of $5,000–$50,000 and volume MOQs of 50–500+ units. Pricing is quote-based, with medical-grade displays commanding 2–3x standard industrial pricing. Revenue is generated almost entirely from hardware unit sales, supplemented by OEM design services and post-sale technical support; pricing is not publicly disclosed. Manufacturing runs on three production lines in a 6,000 sqm ISO-certified facility in Beijing with stated capacity of 100,000 units per month, supported by regional sales/technical offices in Shenzhen and Hangzhou and a 50+ person international sales team. STONE holds ISO 9001, ISO 14001, ISO 13485, AS9100, CE, and RoHS certifications, and reports 3,000+ cumulative global customers including Siemens, ThyssenKrupp, National Instruments, Bosch, Samsung, GE, Toshiba, Tata Group, and State Grid Corporation of China.

The go-to-market combines a product-led growth motion (free GUI software and 1-unit sample orders) with direct OEM enterprise sales and inside-sales coverage through regional offices. Marketing is content-driven, with 100+ technical articles, an active developer forum, and industry exhibition participation. The company is founder/management-owned with no disclosed institutional investment, no parent entity, and no subsidiaries. Revenue, funding history, and unit-level financial metrics are not publicly disclosed.
