16X4 LCD DISPLAY

The 1604 16×4 LCD Display is an alphanumeric liquid crystal display (LCD) capable of displaying 16 characters per line across 4 lines, making it suitable for presenting larger amounts of text, numerical data, and system status information. It is commonly based on the HD44780 controller and supports both parallel and I²C interfaces (with an optional I²C adapter), allowing easy integration with microcontrollers such as Arduino, ESP32, STM32, Raspberry Pi, and PIC. The display features a blue backlight with white characters, adjustable contrast, low power consumption, and reliable performance for embedded applications. Due to its larger display area and ease of interfacing, the 1604 16×4 LCD is widely used in industrial control systems, biomedical instruments, IoT devices, data acquisition systems, measurement equipment, home automation, and educational electronics projects.
