Basic Information
40X2 Dot Matrix LCM Module is a long-format character display for extended labels, parameter names, operating values, and diagnostic messages. It uses STN Negative technology, white LED backlight, and IIC/I2C communication to reduce wiring in wide panels. Supporting 3.3V or 5.0V drive voltage, wide-temperature operation, and low power use, it suits meters, control systems, test instruments, automation equipment, smart terminals, and customized electronic products requiring clear two-line information display performance.

Key Specifications
40X2 Dot Matrix LCM Module SJXD4002A-IIC is designed for interfaces that need long text lines, wider numeric fields, and more complete device messages than standard compact character screens. It uses a 40×02 character format, giving each row enough space for extended labels, parameter names, and operating values. The module size is 182.0×33.5×20.5 mm, with a 154.4×16.5 mm viewing area, 3.3V/5.0V drive voltage, AIP31066 drive IC, STN Negative LCD type, white LED backlight, 06:00 viewing angle, and IIC/I2C interface.
Design Standards
40X2 Dot Matrix LCM Module focuses on long-format readability, simplified signal routing, and stable use in equipment interfaces. The IIC/I2C interface helps reduce wiring compared with wide parallel layouts, while the STN Negative display style supports bright characters on a darker background. It operates from -20°C to +70°C and stores from -30°C to +80°C. The module also supports high contrast, low power consumption, anti-interference performance, multiple color combinations, source code support, customization, 1–3 day samples, and cost-effective production.
Applications
40X2 Dot Matrix LCM Module is suitable for systems that need to show longer information without moving to a graphic LCD, such as instrument readouts, equipment settings, diagnostic text, production data, menu lists, and warning messages. It can be used in meters, equipment control panels, information display systems, industrial controls, test instruments, automation devices, smart terminals, and customized electronic products. Its 40×2 format gives engineers more horizontal display capacity for clear character-based interfaces.
