Display Substrate Capacitor Segmentation for Laser Repair

The capacitor structure is segmented into multiple independent sub-capacitors (first sub-capacitor, second sub-capacitor, etc.), where each sub-capacitor consists of its own first electrode, second electrode, and dielectric layer. This segmentation allows defective sub-capacitors to be isolated and repaired independently without affecting other sub-capacitors, thus enabling repair capability while preventing short-circuiting of the entire capacitor structure.

The first electrode and second electrode are designed with different geometric configurations (e.g., first electrode extends in first direction, second electrode extends in second direction perpendicular to the first direction). This local differentiation in electrode geometry creates distinct overlapping regions for each sub-capacitor, allowing laser cutting to target specific defective areas without cutting through overlapping regions of other sub-capacitors, thereby preventing short-circuits while maintaining repairability.

The capacitor structure is divided into multiple independent sub-capacitors with distinct first electrodes, second electrodes, and dielectric layers. Each sub-capacitor occupies a specific overlapping region, allowing defective portions to be identified and repaired independently. This segmentation maintains compact layout through controlled overlapping while enabling easy isolation and repair of defective sub-capacitors without affecting other regions.

Different sub-capacitors are designed with locally differentiated electrode geometries and orientations (first direction vs. second direction), creating unique overlapping patterns for each sub-capacitor. This local quality differentiation allows repair personnel to target specific defective sub-capacitors using laser cutting without accidentally cutting through overlapping regions of adjacent sub-capacitors, thus maintaining both compact layout and ease of repair.

The capacitor structure is segmented into multiple independent sub-capacitors, each with its own first electrode, second electrode, and dielectric layer. This segmentation can be achieved through standard manufacturing processes by adjusting patterning steps, thus maintaining manufacturing simplicity. At the same time, the segmented structure provides repair flexibility by allowing individual sub-capacitors to be isolated and repaired independently when defects occur, without requiring redesign of the entire capacitor structure.

The first electrode and second electrode are designed with locally differentiated geometries (different extension directions, different shapes) that can be implemented through conventional photolithography and etching processes. This local quality differentiation provides repair flexibility by creating distinct overlapping regions for each sub-capacitor, enabling targeted laser cutting repairs while maintaining compatibility with existing manufacturing processes and simplicity.
