Small 89.8 KB datasheet in PDF format for the PG240160-B graphic LCD module series. Following the usual numbering, this is a 240 x 160 dot panel, and the trailing B looks like a series or document revision letter. Such a sheet normally lists pin functions, absolute maximum ratings, supply and contrast voltages, and an outline drawing with mounting holes. Repairers use it to check whether the display is receiving correct power and bias, or to find a drop-in equivalent. Confirm the full part code on the module before relying on the figures.
