An LCD display module is a self-contained electronic component that pairs a liquid crystal display panel with a built-in driver IC, interface circuitry, and a backlight. It is widely used in microcontrollers (like Arduino and Raspberry Pi) to show text, numbers, or simple graphics.
| • Display Format | 16 characters per line × 2 lines (32 total characters) |
| • Operating Voltage | 4.7V to 5.3V (typically 5V DC) |
| • Current Consumption | ~1mA without backlight; higher with LED backlight on |
| • Module Dimensions | ~80.0 mm (W) × 36.0 mm (H) × 10.0–11.0 mm (T) |
| • Viewing Area | ~64.5 mm to 66.0 mm (W) × 14.5 mm to 16.0 mm (H) |
| • Controller IC | Built-in HD44780 or equivalent (e.g., S6A0069) |
| • Interface | 16 pins supporting 4-bit or 8-bit parallel data mode, or 4 wires via an optional I2C Adapter Module |
| • Backlight | LED (commonly white, blue, or yellow-green) |
