PDF datasheet covering the PG24064LYS-ITA-H, a 240 x 64 dot graphic LCD module in the Powertip PG series. The file is 613 KB, so it likely includes detailed drawings and timing charts alongside the pin table and electrical ratings. Repair technicians rely on it to identify the connector pins, check contrast voltage and backlight supply, and confirm the controller interface before swapping a panel. Several LYS, LRU and LRS variants share this 240x64 size, so match the complete suffix on the module before trusting the details.
