Specification PDF, about 397 KB, for the PE160240BRF-001-H display module. The 160240 code most likely describes a 160 x 240 dot graphic LCD, and the 001-H suffix marks a particular build. A document of this size usually includes block diagram, controller interface, electrical and optical characteristics plus a dimensioned outline. Use it to trace the panel connector, check bias and backlight voltages, and confirm that any replacement module matches before fitting it.
