End-to-end traceability with digital lot management
OLED plant: end-to-end traceability from glass substrate input to finished panel

/Factova AI VisionOverview
- Display manufacturing from Color Filter → Cell → Module passes through multiple independent plants and process stages before a finished panel is made
- Each stage is located at a different site, with different equipment and in a different country, and each process manages and operates its own lots
- Color filter, cell and module processes are distributed across multiple sites in Korea and overseas, so data from several plants accumulates sequentially until the final panel is completed
Challenge
- Problems originating in the color filter plant do not surface immediately: fine pattern defects or particles may pass in-house inspection within limits, yet appear as defects only after bonding in the cell process and assembly into the finished product in the module process
- The key is not “finding the defect” but tracing which plant, lot, equipment and point in time the defect originated from
What Was Applied
- Established a digital lot management system to secure traceability across all processes, from glass substrate input to finished panel
Capabilities Applied
01
End-to-End Traceability across all processes based on Tracing KeysContinuously assigns and manages Tracing Keys (PO, WO, Invoice number, Lot ID, etc.) from raw material input through cell and module processes to final panel completion, tracing the links between raw materials, processes, equipment and finished products without breaks even when lots are split, merged or substituted
02
Data connectivity across the entire processConnects the full history of each lot into one—input raw materials, equipment passed through, process conditions, inspection data, sensor values and Run Notes—to build an analyzable data foundation
03
Supports scoping of abnormal products and defect root-cause analysisTracing of responsible material lots (instant lookup of in-house and already-shipped inventory locations by serial number, panel ID, pallet ID and invoice number) and original-shipment tracing for customer returns (real-time lookup of original shipment information upon customer return)
Average results across LG affiliates
Time to locate target Lot products↓ 95% ReducedReal-time lot location and status tracking
Rework, F-cost↓ 30% ReducedLot tracing reduces rework and F-Cost
Damage from defect spread↓ 16% ReducedDefective processes put on Hold immediately
Recall scope↓ Minimized ReducedIn an RMA, only the problem lots are recalled rather than entire lots
