Mother Substrate Rib Partitions for Accurate OLED Inspection

The patent applies preliminary action by forming inspection patterns and reference marks on the substrate before the actual OLED elements are manufactured. This allows inspection infrastructure to be prepared in advance, enabling accurate measurements without adding complexity to the element formation process itself. The inspection patterns are created during initial substrate processing steps.

The patent uses copying by creating test patterns that replicate the structure and materials of actual OLED elements on the same substrate. These copied structures serve as reference samples for inspection, allowing accurate measurement of element formation without needing to inspect every actual element individually. The test patterns copy the critical geometric and material properties of production elements.

The patent merges inspection functionality with the manufacturing substrate by integrating inspection patterns, reference marks, and test elements directly into the substrate structure during production. This combination eliminates separate inspection substrate preparation steps and allows simultaneous use of the substrate for both element formation and inspection, maintaining productivity while ensuring quality.

The substrate is designed with multi-functionality, serving both as the base for OLED element formation and as the carrier for inspection patterns and reference marks. This universal substrate structure performs multiple functions - production and inspection - without requiring separate dedicated inspection substrates, thereby maintaining manufacturing efficiency while enabling comprehensive quality verification.
