How Does the LCD 16×2 JHD 162A Display Work?

The LCD 16×2 JHD 162A Display uses the HD44780 controller, which communicates with a microcontroller through a parallel interface. It can operate in two modes:

• 4-bit Mode: Requires 4 data lines, conserving microcontroller pins
• 8-bit Mode: Uses 8 data lines for faster data transfer

In addition to the data lines, the module uses control pins:

1. RS (Register Select): Chooses between command mode or data mode
2. RW (Read/Write): Selects between read or write operations
3. EN (Enable): Latches the data into the display on a high-to-low pulse

The backlight and contrast can be adjusted to suit different lighting conditions, ensuring optimal readability. Libraries like LiquidCrystal.h in Arduino make it extremely simple to program and control this display.
