Segmented Pixel Driving Electrode for Light Emitting Display Panel Defect Isolation

The pixel driving electrode is divided into multiple separate first electrodes (e.g., first electrode, second electrode, third electrode) instead of using a single continuous electrode. This segmentation isolates particle defects to specific regions, preventing short circuits from propagating to other pixels. Each first electrode can be independently covered by the second electrode, ensuring that even if particles are present, only the affected region is impacted.

The common electrode is divided into multiple separate common electrodes, with each common electrode connected to a specific first electrode through a corresponding connection hole. This segmentation ensures that a short circuit in one pixel (e.g., between the first electrode and common electrode) is isolated to that pixel only, preventing the defect from affecting other pixels or degrading overall panel quality.

The electrode structure is segmented into multiple isolated first electrodes covered by separate second electrodes. When particles are present on the pixel driving electrode during manufacturing, the segmented structure ensures that particles can only cause defects in the specific region where they are located. The isolation between first electrodes and the corresponding coverage by second electrodes prevents particle-induced defects from propagating to other regions, thereby maintaining higher yield rates.
