Once you have identified a specific model number (e.g., "DV-20200") or a controller chip (e.g., "T6963C"), use these as your primary search terms:
The longevity of Phico displays in the surplus market is a testament to their rugged design. Unlike modern OLEDs that suffer from organic degradation, these passive-matrix LCDs can operate for decades if kept within their thermal limits. For engineers and enthusiasts seeking the "PDF datasheet," the most effective strategy is to search for the specific driver chip part number located under the black epoxy "blobs" on the board, as the command set for these chips is what ultimately dictates how the display functions.
