| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Electronics (electronics) | enabling | 68% | expert_inference | Electronics provides a capability that enables this technology without being the only possible path. |
|
| Advanced Chemistry (advanced_chemistry) | enabling | 68% | expert_inference | Advanced Chemistry provides a capability that enables this technology without being the only possible path. |
|
| Glassmaking (glassmaking) | enabling | 68% | expert_inference | Glassmaking provides a capability that enables this technology without being the only possible path. |
|
| Early Plastics (plastics) | historical_predecessor | 75% | expert_inference | Early Plastics (Bakelite) is an earlier historical predecessor or foundation, not a one-to-one engineering dependency. |
|
| Transistors (transistors) | enabling | 68% | expert_inference | Transistor technologies enable LCD architectures, but many optical-display pathways are contextual and do not require a single transistor lineage. |
