It features a 98.0×60.0×15.0 mm module size, 76.0×25.2 mm viewing area, 3.3V/5.0V drive voltage, ST7066/AIP31066 driver IC, 16PIN interface, white LED backlight, STN Positive LCD type, 06:00 viewing direction, -20°C to +70°C working temperature, and -30°C to +80°C storage temperature.
Design Standards
20X4 Character LCD Display Module is built for direct controller connection, stable character output, and easy use in electronic product design. The 16PIN interface provides a familiar parallel connection structure, helping engineers integrate the module into control boards, test equipment, and display panels without relying on a serial adapter. Its STN Positive display mode presents dark characters on a bright background, while the white LED backlight creates a clean and neutral viewing effect for modern equipment interfaces. The module also supports high contrast, wide-temperature operation, low power consumption, anti-interference performance, multiple color combinations, technical documentation, source code support, customization, 1–3 day samples, cost-effective quality, and batch delivery within fast project schedules.
Applications
20X4 Character LCD Display Module is suitable for products that need more visible data than a basic two-line screen while keeping the structure simple and economical. It can display parameter pages, equipment states, menu layers, error codes, count values, service notices, user commands, and operating instructions in a four-line character layout. Typical uses include measuring instruments, control panels, information display systems, industrial equipment, medical devices, household appliances, consumer electronics, communication products, Arduino projects, and DIY development boards. Its 20×4 capacity, STN Positive readability, white backlight, and 16PIN hardware connection make it useful for reliable text display in long-running device interfaces.
