The Phico D-0 94V-0 refers to a lineage of LCD modules manufactured by Data Vision (also known as Data International Co., Ltd.). The name "94V-0" is not a part number but a flammability safety rating from Underwriters Laboratories (UL), indicating the PCB material will self-extinguish within 10 seconds of ignition. Core Technical Profile
While the "D-0 94V-0" branding is found on many distinct models, the most common variants are industrial-grade character and graphic displays used in factory automation, telecommunications, and legacy computing. The Ultimate Guide To UL 94V-0 Circuit Boards - Jhdpcb
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.

These timings are easily met by any microcontroller, including Arduino at 16MHz.
Without the specific datasheet, identifying the pinout requires caution. However, most Phiaco/Phico modules follow a standard layout:
Warning: Always verify voltage levels with a multimeter if possible before connecting to a microcontroller, as reverse polarity can damage the panel.
Introduction In the realm of embedded systems and hobbyist electronics, few components are as ubiquitous as the alphanumeric LCD display. While branded components often come with comprehensive documentation, a significant portion of the market relies on generic modules identified only by cryptic PCB codes. One such query involves the "PHICO D0 94V0 LCD Display." Although "PHICO" is not a recognized semiconductor manufacturer, analyzing the string "D0 94V0" reveals that this document is not a datasheet for a specific product but rather a technical profile for a standard 16x2 or 20x4 character LCD built on a UL 94V-0 compliant printed circuit board.
The Significance of "94V0" The most concrete piece of information in the query is "94V0." This is not a feature of the LCD glass itself but a safety standard for the PCB driving the display. According to UL (Underwriters Laboratories) Standard 94, "V-0" indicates that the material stops burning within 10 seconds on a vertical specimen, with no flaming drips. For an engineer, seeing "94V0" on the silkscreen guarantees that the display's controller board meets fire safety regulations for consumer electronics. Therefore, the "PHICO D0" is likely a generic LCD module manufactured for industrial use where PCB flammability is a legal requirement. if specified) |
Decoding "D0" and Interface Presumption The code "D0" is non-standard but typically refers to a variant in a series. Given the context of small LCDs, this likely points to a parallel interface using the Hitachi HD44780 (or equivalent) controller. Most character LCDs with a 94V0 rating feature a 16-pin interface (or 14-pin for simple versions). The "D0" might denote the specific backlight color (e.g., White or Blue) or a specific temperature range (Standard vs. Wide). Without a genuine PHICO datasheet, one must infer the electrical characteristics: logic voltage of 5V (or 3.3V for modern variants), typical contrast adjustment via a potentiometer on pin 3 (V0), and a default character set of 5x8 dots.
Mechanical and Electrical Assumptions Based on standard 94V0-rated displays, the "PHICO D0" likely measures 80mm x 36mm for a 16x2 character layout. The datasheet (if it existed) would show a standard pinout: Pin 1 (Vss/Ground), Pin 2 (Vdd/+5V), Pin 3 (V0/Contrast), Pin 4 (RS), Pin 5 (R/W), Pin 6 (E), and Pins 7-14 (DB0-DB7). The "94V0" rating suggests the module operates between 0°C and 50°C. A missing datasheet forces the user to reverse-engineer these parameters, often by treating the device as a "standard HD44780 clone," which is a safe assumption for 99% of generic LCDs.
The Challenge of Generic Components 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."
Conclusion The "PHICO D0 94V0 LCD Display" is a phantom product that exists physically but not in formal documentation. The string "94V0" is the only technical guarantee, certifying the PCB as flame-retardant. The "D0" likely signifies a minor mechanical variant of a standard HD44780-compatible character LCD. While a dedicated datasheet for "PHICO" cannot be produced, the device can be successfully driven using generic LCD library examples for Arduino or PIC microcontrollers. Ultimately, this query demonstrates that for generic displays, the UL safety rating on the PCB is often more reliable than the missing brand name on the label.
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.
