The difficulty in locating a "PHICO D0" datasheet highlights a major issue in the electronics supply chain: rebranding and generic labeling. Factories in Shenzhen or Taiwan produce millions of "no-name" LCDs, stamping "94V0" for safety and a batch code like "D0" for internal tracking. Consequently, an engineer must rely on community consensus rather than a manufacturer’s document. To interface with this display, one would ignore the "PHICO" brand entirely and instead search for a datasheet for a "Standard 16x2 LCD with 94V0 PCB."

Phico manufactured several classes of alphanumeric and graphic displays. Most of these legacy modules rely on industry-standard controller chips, making them highly compatible with modern microcontrollers like Arduino, ESP32, and Raspberry Pi. 1. Character LCD Modules (e.g., 16x2, 20x4)

The mark is a widely recognized footprint in the surplus electronics, repair, and industrial automation industries. If you are reverse-engineering an old medical device, repairing a legacy point-of-sale (POS) terminal, or retrofitting an industrial controller, finding the exact technical specifications for this display can be challenging.

Phico D-0 94V-0 (often branded under Data Vision ) is a legacy character LCD module commonly used in industrial automation, PLC systems, and older electronic equipment. The "94V-0" in its name refers to its UL flammability rating, indicating that the PCB material is flame-retardant and self-extinguishing. Alibaba.com Technical Specifications

The Phico D0 94V0 is a legacy liquid crystal display (LCD) module frequently found in vintage electronics, industrial equipment, testing instruments, and early consumer devices. If you are repairing, retrofitting, or repurposing a device containing this display, finding the exact datasheet can be challenging. This is because "94V-0" is not an explicit part number, but rather a UL (Underwriters Laboratories) flammability rating for the printed circuit board (PCB).

If you physically have this display, do not search for "PHICO." Instead:

This is not a model number . It is a flammability rating established by Underwriters Laboratories (UL 94). A "94V-0" rating signifies that the plastic/fiberglass PCB materials are self-extinguishing within 10 seconds during vertical flame testing.
