Technical datasheet in PDF format, 1.23 MB, covering the PD104SL3 display panel, likely a 10.4 inch class TFT judging by the 104 code. Sibling SL5 and SL6 versions exist, so treat the variant number as significant. Contents normally include mechanical outline, connector pin list, electrical characteristics, timing diagrams and backlight ratings. Use it to trace signals at the panel connector, measure supply rails while diagnosing a dark or flickering screen, and check compatibility before swapping panels in equipment.
