The most reliable way to identify your display is to locate the main controller IC(s) on the board and note their part numbers. This single piece of information is often enough to determine the entire interface and operational logic of the display. Many Phico D-0 series displays use popular, well-documented controller chips, including:
Most PHICO modules found in legacy hardware fall into two broad architectural categories. Both rely on standardized industry-standard controllers. Category A: Alphanumeric Character LCDs (16x2, 20x2, 20x4) phico d0 94v0 lcd display datasheet pdf

This is arguably the most critical piece of information. The LCD's primary controller chip determines the pinout, power supply, and the command set required to drive it. The PHICO D0 series was manufactured with at least two distinct controllers:
If you have identified the display as an HD44780-compatible character LCD, you can use the standard LiquidCrystal library that comes with the Arduino IDE. The standard wiring is as follows: Many Phico D-0 series displays use popular, well-documented
A : While most of these displays are 5V devices, some may tolerate 3.3V logic levels, but they may be unreliable. Use a level shifter for consistent operation.
