• Low power consumption, high anti-interference performance
• Support for multiple color combinations
• Provide a complete set of one-stop technical information and source code
• Supports customization
• Supports 1-3 day samples
• High quality and cost-effective

Key Specifications

Character 4002 LCD SJXD4002A-IIC is a monochrome 40×2 display module for long text strings, extended parameter names, equipment labels, and numeric information. Its 182.0×33.5×20.5 mm module size and 154.4×16.5 mm viewing area provide a wide character window for two-line data presentation. The module supports 5.0V or 3.3V drive voltage, AIP31066 drive IC, STN Positive LCD type, yellow LED backlight, 06:00 viewing angle, and IIC/I2C interface for MCU connection.

Design Standards

Character 4002 LCD is designed for projects that require a long horizontal reading area with simplified wiring. The STN Positive display mode creates a clean monochrome viewing effect, while the yellow LED backlight improves character recognition in equipment panels. Its IIC/I2C interface reduces connection complexity and supports easier integration with embedded control systems. The module also supports -20°C to +70°C operation, -30°C to +80°C storage, high contrast, low power consumption, anti-interference performance, color options, source code support, customization, and 1–3 day samples.

Applications

Character 4002 LCD is suitable for devices that need longer text output without using a graphic display. It can show equipment instructions, production values, test results, menu lists, alarm descriptions, and operating records across two wide rows. Common application areas include meters, equipment control panels, information display systems, industrial controllers, embedded terminals, automation devices, testing instruments, and customized electronic products. Its 40×2 layout gives engineers more space for readable character content while keeping the module structure practical and cost-effective.
