Based on the PHICO D0 94V0 datasheet PDF, the key features and specifications of the display module are:
A : The extra pins may be for features like buttons, LEDs, or multiple backlight anodes/cathodes. For the 24-pin display, only 16 pins are used for the LCD itself, with the others connected to buttons and LEDs.
Since a single "Phico D0" datasheet doesn't exist, here is a logical, step-by-step plan to find the exact specifications for your specific LCD. phico d0 94v0 lcd display datasheet pdf
Because "94V-0" is printed on millions of circuit boards worldwide, look closely at the edges of the PCB for a secondary stamped or printed part number (such as PHICO SS-M , 1074 , 1620 , or similar alphanumeric strings) to pinpoint the exact display variant. Common Architecture: The HD44780 Standard
When you look at the printed circuit board (PCB) attached to the back of an LCD module, you will frequently see text etched into the copper or silkscreened onto the board reading "PHICO D0" and "94V-0". Based on the PHICO D0 94V0 datasheet PDF,
) to generate negative bias current required to drive larger liquid crystal grids smoothly, avoiding ghosting or fading text. Where to Find the PDF and Replacement Screens
What are the (e.g., 16x2, 20x4)?
& "Data Vision" : The markings "PHICO" and "Data Vision" likely refer to either the manufacturer of the printed circuit board (PCB) or the final assembler/distributor of the LCD module. Data International (or Data Vision) is noted to use PHICO as a source for their display PCB designs.
: Can be found at S&S Electrical Supply for roughly $20. Because "94V-0" is printed on millions of circuit
The second line of a 16x2 display starts at DDRAM address 0x40 (or 0xC0 depending on the controller revision). Your PHICO datasheet will specify this.
