If you’d like me to continue now, upload clear photos of the display (front, back, and close-ups of any chips/markings) or confirm whether "94V0" is just the PCB flammability marking. I will then search for the exact datasheet PDF.
(You can also tell me if you only need general LCD datasheet content—pinout, voltage levels, timing—rather than this specific part.)

The Phico D-0 94V-0 (often branded as Data Vision Phico) is a legacy LCD module manufactured by Phico, a PCB manufacturer in Taiwan. The markings "D-0" and "94V-0" are generic designations; "94V-0" specifically refers to a UL flammability rating for the PCB material rather than the display model itself.

Because "Phico D-0 94V-0" is a generic PCB marking, it can appear on widely different display types, including: Alphanumeric: 16x1 or 16x2 character displays.
Graphic/TFT: Some versions are 5.7-inch TFT screens or larger monochrome graphic boards with 20 pins instead of 16.
Custom Industrial: Used in specialized equipment like autosamplers.

Finding the exact PDF for older or generic Phico modules can be difficult as manufacturers often update part numbers. Use the following search strategies to locate the datasheet:
The Phico D-0 94V-0 (often branded as Data Vision) refers to a series of LCD modules commonly found in industrial equipment, such as chromatography autosamplers. While "94V-0" is a standard UL flammability rating for the PCB material rather than a model number, these modules typically follow the standard HD44780-compatible interface.

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
While Phico produced several variants under this designation (such as the P124-1 or P141-14), the most common configuration is a 16x2 character display Display Type : Character LCD (typically 16 characters x 2 lines). Module Dimensions : Approximately Viewing Area Operating Voltage : 5V DC (Logic supply range Supply Current : 2.0 to 5.0 mA. Controller Compatibility : Generally uses the standard Hitachi HD44780
or compatible controllers (like the Samsung KS0066U), making it easy to interface with modern microcontrollers like Arduino. Interface and Pinout The module typically features a 16-pin interface , which is the industry standard for character LCDs: Description Ground (0V) Power Supply (+5V) Contrast Adjustment (via potentiometer) Register Select (0=Command, 1=Data) Read/Write (usually grounded for Write) Enable Signal Data Bus lines (8-bit or 4-bit mode) Backlight Anode (+) Backlight Cathode (-) Review and Performance New In Box PHICO D-0 94V-0 LCD Display Screen | eBay UK
Because exact part numbers for LCDs can be complex (often consisting of a manufacturer code, a screen size, and a revision code), it is likely that "D0 94V0" is a specific revision or part of a larger model number (e.g., from a manufacturer like Phiaco or a similar brand).
Below is a guide on how to find the specific datasheet PDF, along with the typical technical specifications you can expect from a display bearing this identification.
Even without the PDF, you can solve 90% of issues with the PHICO D0 94V-0.
Likely Full Part Number Structure: 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.
Since obtaining the exact PHICO D0 PDF can be difficult, we can infer the specifications based on thousands of similar HD44780-compatible displays. These are highly standardized. Use the table below as a working reference until you locate the original datasheet.
