Basic Information
20X4 line Character Module offers a four-row LCD format for equipment that needs clearer menu grouping, values, alerts, and system messages on one screen. Its VA negative display, white LED backlight, IIC interface, and 3.3V/5V drive support readable contrast with fewer control lines. The 98.0x60.0mm module suits industrial controllers, instruments, medical devices, appliances, terminals, and development boards requiring stable text output during setup, monitoring, diagnostics, and daily operation tasks.

Key Specifications
20X4 line Character Module is designed for equipment that needs four rows of organized text instead of a limited two-line readout. The SJXD2004A-IIC model provides a 20×4 character format, giving more space for menus, alarms, values, and system messages on one screen. It uses a 98.0×60.0×20.0 mm module outline and a 76.0×25.2 mm viewing area, making it suitable for panels that require clearer information grouping. The module supports 3.3V/5.0V drive voltage, ST7066/AIP31066 driver IC, IIC/I2C interface, white LED backlight, VA Negative LCD type, 06:00 viewing angle, -20°C to +70°C working temperature, and -30°C to +80°C storage temperature.
Design Standards
20X4 line Character Module is built to improve information layout, reduce wiring complexity, and support stable embedded communication. The IIC/I2C interface lowers the number of required control lines, helping engineers simplify PCB routing and reserve more MCU pins for buttons, sensors, relays, or communication circuits. Its VA Negative display structure creates a dark-background visual effect, while the white LED backlight improves character recognition for control panels and instrument interfaces. The design also supports high contrast, wide-temperature use, low power consumption, anti-interference performance, multiple color options, technical documentation, source code support, customization, 1–3 day sample evaluation, and fast batch delivery planning.
Applications
20X4 line Character Module is suitable for products that need more visible information than standard 16×2 or 20×2 LCD modules. It can display multi-step menus, machine parameters, fault descriptions, process data, service reminders, timer records, user instructions, and operating status across four clear rows. Common application fields include industrial controllers, measuring instruments, automation panels, medical devices, household appliances, information terminals, consumer electronics, access equipment, and DIY development boards. Its 20×4 format, IIC connection, VA Negative contrast, and larger viewing area make it practical for interface designs that need richer text output while keeping a simple character LCD structure.
