PDF reference sheet for the PG128128ERS-ATA-B, a Powertip graphic LCD module with a 128 x 128 dot format. At 191 KB it should cover the core specifications: outline drawing, connector pinout, operating voltages, backlight data and interface timing. Technicians use it to verify supply rails on the display connector, identify the controller signals and source a compatible replacement. The ERS letters separate this version from the LRU and LRF variants of the same size, so compare suffixes carefully against the part label.
