The datasheet explicitly shows that Pin 1 is marked by a copper dot on the film edge. Misalignment by 0.1mm will short VGH (30V) to VSS.

Always cross-reference the "Lot Number" on the physical COF film (located near the sprocket hole) with the "Wafer Fab Code" in the datasheet's appendix. If the codes don't match the revision table, you are likely holding a counterfeit part. The datasheet explicitly shows that Pin 1 is
