Datasheet for the PD104SL5 TFT panel, provided as a 1.29 MB PDF. The 104 code points to a 10.4 inch class display, one of several SL-series variants that may differ in brightness, interface or backlight. The sheet is useful for identifying interface pins, supply voltage and power sequencing, input timing and backlight drive details. In practice it helps when repairing industrial terminals or replacing a failed panel, confirming whether a candidate replacement is truly compatible. Verify the model printed on the panel rear first.
