It features a 146.0×62.5×19.5 mm module size, 3.3V/5.0V drive voltage, ST7066/AIP31066 driver IC, IIC/I2C interface, white LED backlight, STN Negative LCD type, 06:00 viewing direction, -20°C to +70°C working temperature, and -30°C to +80°C storage temperature.
Design Standards
20 Character x 4 Line LCD Display is built to combine a larger text area with simplified connection design. The IIC/I2C interface helps reduce wiring complexity, allowing engineers to connect the module to controllers, development boards, and compact PCB layouts with fewer signal lines. Its STN Negative display mode creates a dark-background visual effect, while the white LED backlight helps highlight characters clearly in operating panels. The module also supports high contrast, wide-temperature performance, low power consumption, strong anti-interference ability, multiple color combinations, technical documentation, source code support, customization, 1–3 day sample supply, and fast batch delivery planning.
Applications
20 Character x 4 Line LCD Display is suitable for products that need organized multi-row information in a clear character format. It can present parameter lists, setup menus, sensor readings, alarm messages, operation steps, production data, service reminders, and equipment status across four readable lines. Common application fields include industrial controllers, measuring instruments, medical devices, communication equipment, automation systems, home appliances, consumer electronics, information display terminals, and DIY development projects. Its 20×4 format, I2C control, white backlight, and STN Negative readability make it practical for interfaces that need richer text output, cleaner wiring, and dependable daily operation.
