Basic Information
Industrial Character Screen provides a 20x4 LCD format for equipment that needs organized menus, values, alarms, and operating feedback on one panel. Its VA negative display, white LED backlight, IIC interface, and 3.3V/5V drive support clear contrast with fewer control lines. The 98.0x60.0mm body suits industrial controllers, instruments, medical devices, terminals, appliances, and development boards requiring stable multi-line text output during setup, diagnostics, monitoring, maintenance, and daily equipment operation tasks.

Key Specifications
Industrial Character Screen is a 20×4 LCD module designed for equipment that needs more structured text space on one display. The SJXD2004A-IIC model provides four rows of character output, making it easier to arrange operating data, menu layers, alarm codes, and setting values. It features a 98.0×60.0×20.0 mm module size, 76.0×25.2 mm viewing area, 3.3V/5.0V drive voltage, AIP31066/ST7066 driver IC, IIC/I2C interface, white LED backlight, VA Negative LCD type, 06:00 viewing direction, -20°C to +70°C working temperature, and -30°C to +80°C storage temperature.
Design Standards
Industrial Character Screen is developed for industrial-style control panels that require stable communication, clear information grouping, and reduced wiring work. The IIC/I2C interface lowers the number of control lines, helping engineers simplify PCB design while keeping enough MCU pins for sensors, keys, relays, or external communication ports. Its VA Negative display mode creates a dark visual background with strong text contrast, while the white LED backlight supports clean readability in equipment interfaces. The module also supports low power operation, high anti-interference performance, wide-temperature use, multiple color combinations, complete technical information, source code assistance, customization, 1–3 day sample testing, and fast batch delivery planning.
Applications
Industrial Character Screen suits products that need to show several groups of information at the same time without using a graphic LCD. It can present process values, device status, fault details, setting menus, maintenance reminders, timer records, user instructions, and operating feedback across four readable lines. Common application areas include industrial controllers, automation panels, measuring instruments, medical equipment, access terminals, home appliances, information display systems, consumer electronics, and DIY development boards. Its 20×4 layout, IIC connection, VA Negative contrast, and larger viewing area make it practical for compact equipment that needs richer text display and reliable panel integration.
