It supports 3.3V/5.0V drive voltage, ST7066/AIP31066 driver IC, IIC/I2C interface, white LED backlight, STN negative LCD type, 06:00 viewing angle, -20°C to +70°C operation, and -30°C to +80°C storage.

Design Standards

Character I2C Display Screen is built for simplified MCU connection, stable text control, and dark-background readability in embedded equipment. The IIC/I2C interface helps reduce wiring compared with traditional parallel LCD modules, while the STN negative structure creates a clear contrast effect for modern control panels. Its design also supports low power consumption, high anti-interference performance, multiple color combinations, complete technical documents, source code support, customization service, 1–3 day sample preparation, high cost performance, and fast batch delivery planning within 15 days.

Applications

Character I2C Display Screen fits devices that need organized two-line information instead of complex graphic output. It can show setting menus, operating status, error codes, measurement values, user instructions, timer data, and basic system messages. Typical uses include meters, equipment control panels, information display systems, industrial controllers, home appliances, medical devices, consumer electronics, and DIY development projects. Its 20×2 layout, I2C communication, white backlight, and STN negative viewing effect make it practical for product interfaces that require more text capacity with fewer control pins.
