Key specs from the official datasheet / distributor listing
| Spec | Value |

| Description | 4 digit, 0.17 in, 7-segment custom LCD panel |
| Display type | TN - Twisted Nematic |
| Display mode | Reflective |
| Backlight | Without backlight |

- Pass: the symbol has 12 terminals, which matches the datasheet's 12 pins.
- Mismatch / incomplete data: all terminals are currently just generic numbered terminals with:
- no pin names
- no pin descriptions
- all pin types set to Bi-Directional
- That means the symbol is structurally the right size, but semantically incomplete versus the datasheet. The sync rules specifically call for exact datasheet-derived pin numbers, names, and functions rather than generic placeholders
- Pass: the footprint has 12 pads, so the pad count matches the symbol and datasheet.
- Likely okay mechanically: the attached footprint/3D model assets exist, and the part dimensions line up with the published package/module dimensions.
- Limitation: I could not extract the exact pad numbering/order or the full pin-function table from the PDF automatically, so I could not conclusively verify pad-to-pin naming/orientation mapping.
- Mismatch: there are currently no pin descriptions in the part project.
- Mismatch: all pins are marked Bi-Directional, which is unlikely to be correct for an LCD glass module because these pins usually have specific COM/SEG drive roles rather than generic bidirectional behavior.
- Per the sync workflow, missing pin names/descriptions/types should be treated as incomplete metadata that needs to be filled from the datasheet pin table
Summary of issues to flag
| Area | Result | Notes |
|---|---|---|
| Datasheet URL | Fixed | Official Lumex PDF added |
| Pin count | Good | 12 symbol terminals / 12 footprint pads / 12 datasheet pins |
| Pin names | Missing | Symbol terminals are unnamed generics |
| Pin descriptions | Missing | No functional descriptions present |
| Pin types | Likely wrong | All set to Bi-Directional |
| Package property | Missing | Should be added as a project property |
| Manufacturer property | Missing | Should be added as a project property |
- naming each terminal,
- setting correct pin descriptions,
- assigning more accurate pin types,
- and verifying footprint pad numbering against the symbol.
