The standard footprint of the Phico D-0 architecture balances space efficiency with optimal outdoor or industrial scannability. The character-based systems (like the 16x1 character layout) adhere to the following physical geometry: 80.0 mm × 36.0 mm × 10.0 mm Active Viewing Area: 65.0 mm × 14.0 mm Dot Size: 0.55 mm × 0.75 mm Dot Pitch: 0.63 mm × 0.83 mm Safety Rating: UL 94V-0 certified flame resistance Standard Pinout Configuration (16-Pin Interface)
Because the Phico D-0 relies on standard character display logic, you do not need a specialized driver. You can easily run it using the standard LiquidCrystal library in the Arduino IDE. Step-by-Step Wiring for 4-Bit Mode
If you require exact physical frame dimensions, screw-hole placements, or timing diagrams, do not look up "94V0". Instead, take your digital camera, snap a photo of the rear PCB markings, and search online for or use generic "HD44780 compliant 1602 specification pdf" resources, as the physical footprints are overwhelmingly standard across manufacturers.

100 mA to 240 mA typical. Note: Always use a current-limiting resistor (e.g., 47 Ωcap omega Ωcap omega ) on Pin 15 to prevent burning out the backlight. Interfacing with Modern Microcontrollers
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
: 5V (typical) with a logic range of -0.3V to 7V Current Consumption : 2.0 to 5.0 mA Datasheet Resources
By the end of this guide, you will have all the technical specifications, pinout details, and command set information necessary to interface this display with Arduino, Raspberry Pi, PIC, or any other microcontroller. The standard footprint of the Phico D-0 architecture
If you are designing a product for medical, automotive, aerospace, or industrial safety markets, you are legally required to use components with a V-0 rating. It means the PCB substrate and the LCD’s plastic frame are flame-retardant. Seeing "94V-0" silkscreened on the back of the display assures compliance with safety regulations (e.g., IEC, UL, CE).
If your PHICO D0 94V0 module features a single row of 14 or 16 pins (or pads), it follows this standard layout: Pin Number Technical Description VSScap V sub cap S cap S end-sub 0V System Reference 2 VDDcap V sub cap D cap D end-sub Power Supply Typically +5.0V (some modern variants use +3.3V) 3 VOcap V sub cap O VEEcap V sub cap E cap E end-sub Contrast Adjust Variable voltage via a 10k Ωcap omega potentiometer 4 Register Select Low = Instruction Register; High = Data Register 5 Read / Write Low = Write to LCD; High = Read from LCD 6 Falling-edge triggered signal to latch data 7 – 14 DB0 – DB7
Locating the exact documentation for legacy liquid crystal displays (LCDs) can be challenging. Components marked with often confuse builders because this text does not represent the part number. Instead, it indicates compliance with the UL 94V-0 flammability standard for plastics and circuit boards.
The PHICO D0 94V0 LCD display is a high-quality display module designed for use in various electronic devices. It features a high-resolution LCD panel with a wide viewing angle, making it ideal for applications where image quality is crucial. The display is manufactured by PHICO, a reputable company known for producing high-quality display modules. Step-by-Step Wiring for 4-Bit Mode If you require
The keyword points to a highly sought-after reference document for legacy character and graphic LCD modules manufactured by Data Vision under the "PHICO" brand. The string "D-0" represents the base logic configuration, while "94V-0" indicates the UL 94V-0 flammability standard rating for the green printed circuit board (PCB) backing, ensuring high thermal resistance and self-extinguishing safety features.
After some digging, I found that the PHICO D0 94V0 is a 4.3-inch TFT LCD display module with a resolution of 480x272 pixels. Here are some interesting features and specs:
