The V.1 suffix, FPC orientation and controller timing need review before replacement screening. Same diagonal size or connector pin count is not sufficient.
Specification, lifecycle and replacement checks
Confirm the complete manufacturer part number and revision on the installed-panel label.
Verify display interface, connector, supply, timing, outline, mounting and optical requirements from current documentation.
Confirm lifecycle status, traceable stock, lead time and a sample-validation plan before production approval.
