Phico D0 94v0 Lcd Display Datasheet Pdf

Phico D-0 94V-0 a generic series of LCD modules manufactured by Data Vision . Because "94V-0" is actually a UL flammability rating

Problem 2: The display turns on, but no characters appear, or only one line works.

Technical Specs:

  1. Count the number of pins (usually 16).
  2. Look up the pinout for a "Standard 16x2 HD44780 LCD."
  3. Check if the backlight requires a separate resistor (usually 5V via a 220-ohm resistor).
  • D often signifies a standard character LCD module.
  • 0 (zero) may indicate the specific backlight color (e.g., Yellow-Green or LED Blue) or the LCD fluid type (STN – Super Twisted Nematic or FSTN – Film Compensated STN).
  • Note: The exact D0 specification is best confirmed via the datasheet, but it frequently points to a 16-character by 2-line display (16x2) with a parallel interface.

Recommendation for your next step:

Important from the datasheet:

The second line of a 16x2 display starts at DDRAM address 0x40 (or 0xC0 depending on the controller revision). Your PHICO datasheet will specify this. Phico D-0 94V-0 a generic series of LCD
