is a commonly encountered, vintage alphanumeric character display module frequently salvaged from old telecommunications equipment, printers, and industrial machinery. Often labeled under "Data Vision" or simply with the manufacturer mark "PHICO D-0 94V-0," these displays are robust, reliable, and widely utilized in hobbyist electronics projects due to their standard pinout.
Connecting Pin 15 directly to 5V without a current-limiting resistor can permanently destroy the backlight module or cause severe voltage drops on your microcontroller board.
indicates that the plastic/fiberglass substrate extinguishes itself within 10 seconds during vertical burn tests, and no flaming drips are permitted. phico d0 94v0 lcd display datasheet pdf
However, after searching technical databases and component libraries, for a "D0 94V0" model. "PHICO" is likely a misspelling of Philco (a vintage electronics brand) or a generic OEM code. "94V0" is not a model number; it is a UL flammability rating (meaning the PCB is made of flame-retardant material).
If this is a Phiaco module, the full model number is likely longer, such as "PHIACO D0-xxxxxx" or similar. To find the exact PDF, check the FPC (Flexible Printed Circuit) cable or the back of the PCB for a longer alphanumeric string. "94V0" is not a model number; it is
PHICO D-0 94V-0 modules most commonly manifest as , alongside a few specialty 128x64 or 240x128 graphic variants. Under the hood, they typically use industry-standard controllers like the Hitachi HD44780 (or equivalent Samsung/STMicroelectronics drivers), ensuring long-term compatibility with standard microcontroller libraries.

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:
When you look at the printed circuit board (PCB) attached to the back of an LCD module, you will frequently see text etched into the copper or silkscreened onto the board reading "PHICO D0" and "94V-0".
