Display Wiring Layout With Auxiliary Lines to Prevent Short Circuits

The patent divides the wiring system into separate segments: first voltage wirings, second voltage wirings, first auxiliary wirings, and second auxiliary wirings. These segmented wirings are connected through connection wirings at specific intervals, creating discrete connection points that prevent continuous short circuits while maintaining electrical functionality. The segmentation allows close spacing overall while ensuring isolation between critical conductive paths.

Connection wirings act as intermediary elements between the voltage wirings and auxiliary wirings. Instead of direct continuous contact between opposing voltage lines, the connection wirings provide controlled intermediate connection points. This intermediary structure enables electrical connection where needed while maintaining gaps and insulation elsewhere, preventing direct short circuits between adjacent voltage wirings.

The patent utilizes multiple layers (first insulating layer, second insulating layer) to create vertical separation between wirings that are horizontally close. By moving the isolation problem from the horizontal plane to the vertical dimension through stacked insulating layers, the design achieves electrical isolation without requiring large horizontal gaps, thus maintaining compact device area while preventing short circuits.

The wiring structure is segmented into discrete sections connected by connection wirings. Between these connection points, gaps are maintained in the wiring paths. This segmentation allows the use of smaller gaps overall compared to a continuous wiring design, as the discontinuous nature of the connections inherently provides isolation points that reduce the required gap distance for preventing short circuits.

The insulating layers serve multiple functions simultaneously: they provide electrical isolation between adjacent voltage wirings, they support and position the auxiliary wirings, and they provide a structural framework for the connection wirings. This multi-functionality reduces the need for additional separate isolation components, thereby limiting the increase in device complexity while achieving comprehensive short circuit prevention.

The patent merges the isolation function with the structural support function by having the auxiliary wirings disposed on the insulating layers. Instead of separate isolation barriers and support structures, the insulating layers perform both roles. This merging reduces the number of discrete components needed, limiting the increase in device complexity while providing robust electrical protection.
