Key Specifications
I2C 20*4 Characters is a four-line character LCD module designed for equipment that needs more text content in one compact display area. The SJXD2004A-IIC model provides a 20×4 character layout, helping users view menu layers, status details, numerical data, and prompt messages without frequent page switching. It features a 98.0×60.0×20.0 mm module outline, 76.0×25.2 mm viewing area, 3.3V/5.0V drive voltage, AIP31066/ST7066 driver IC, IIC/I2C interface, white LED backlight, FSTN Positive LCD type, 06:00 viewing direction, -20°C to +70°C working temperature, and -30°C to +80°C storage temperature.
Design Standards
I2C 20*4 Characters is developed for efficient multi-row display control, simplified wiring, and stable embedded communication. The IIC/I2C interface reduces the number of required controller pins, making PCB design cleaner for systems that also connect buttons, sensors, relays, alarms, or external communication modules. Its FSTN Positive display structure improves character definition on a light background, while the white LED backlight keeps the screen clear for front-panel reading. The module also supports high contrast, low power consumption, anti-interference performance, wide-temperature operation, multiple color options, technical documentation, source code assistance, customization, 1–3 day sample testing, and fast batch production planning.
Applications
I2C 20*4 Characters is suitable for products that need organized four-row information display while keeping a standard character LCD structure. It can present setting menus, device status, measurement values, alarm descriptions, process steps, diagnostic codes, service reminders, and user instructions on one screen. Typical application areas include measuring instruments, industrial controllers, automation panels, medical equipment, access terminals, home appliances, information display systems, consumer electronics, and DIY development boards. Its 20×4 layout, I2C connection, FSTN Positive readability, and white backlight make it practical for compact control interfaces requiring clearer text grouping and efficient hardware integration.
