Display Datasheet Pdf Patched | Phico D0 94v0 Lcd
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
If your display has more than 16 pins and is likely graphical:
Most PHICO character modules use the industry-standard Hitachi HD44780-compatible 16-pin interface: Pin VSS Ground (0V) 2 VDD Power Supply (+5V) 3 VO Contrast Adjustment (via potentiometer) 4 RS Register Select (H: Data / L: Instruction) 5 R/W Read/Write (H: Read / L: Write) 6 E Enable Signal 7-14 DB0-DB7 Data Bus Lines (DB7 used for Busy Flag) 15 A (LED+) Backlight Anode (+5V) 16 K (LED-) Backlight Cathode (0V) phico d0 94v0 lcd display datasheet pdf
Operating these legacy displays in a modern context requires careful attention to the contrast voltage. While the logic typically runs at 5V, the contrast pin often requires a variable voltage between 0V and 5V, usually managed via a 10k-ohm potentiometer. Without this precise adjustment, the display will either appear entirely blank or show solid "blocks" in the character cells, leading many hobbyists to believe the unit is defective when it is simply misconfigured.
Flip your LCD over. Look for a white silkscreen text that says something like: While Phico produced several variants under this designation
For many Phico modules, you can find known pinouts and hookup diagrams shared by other users. Here are some examples from the search results:
" is often printed on the back of these LCD modules, it refers to a generic PCB safety standard ( While the logic typically runs at 5V, the
Connect Phico to Arduino Digital Pins 5, 4, 3, 2 respectively.
Look for a white or silver adhesive barcode label on the back of the PCB. This often contains the true part number (e.g., Character modules: DM-1602, WH1602, or Graphic modules: WG12864 ).
The search for is a classic journey in the world of hardware hacking. While the specific PDF may be cryptic, the underlying truth is that this display is a robust, flame-retardant, HD44780-compatible workhorse.
