A UL 94 plastic flammability standard classification. It indicates that the printed circuit board (PCB) is designed to self-extinguish within 10 seconds when exposed to a vertical flame, a critical safety specification for industrial manufacturing environments. Core Technical Specifications

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)

Look for a pin connected to a small trimpot (a variable resistor) or a voltage divider network. This is the contrast adjustment pin (Vo, Pin 3 for HD44780), which needs a negative voltage (sometimes as low as -17V) for the display to show any characters.
When you land on a datasheet, press Ctrl+F and search for "94V-0". That exact phrase should appear in the "Physical Specifications" or "Safety" section. The character-based systems (like the 16x1 character layout)
The vast majority of character LCD modules manufactured on boards marked by PHICO utilize industry-standard display controllers. In 95% of cases, a character LCD follows the architecture of the controller or its modern equivalents (such as the Sitronix ST7066, Samsung S6A0069, or AiP31066). Typical Functional Block Diagram
While multiple versions exist, most Phico D-0 modules follow these general industrial standards: Power Supply : Typically requires for logic. : Standard parallel interface, often compatible with the HD44780 controller Connector Type : Varies between (standard character) and (graphics or dual-controller) configurations. Dimensions : A common 20x2 character version measures approximately 116mm x 37mm Standard 16-Pin Pinout
To find deeper reference material regarding timing diagrams, instruction sets, and DDRAM mapping, you can bypass the "PHICO" nomenclature and search directly for the standard or Sitronix ST7066 datasheet PDFs, as their functional guidelines apply identically to your module.
