Display Panel Wiring Layout for Alignment-Deviation Tolerance

The patent applies preliminary action by pre-defining precise dimensional relationships between lateral wires, front wires, and back wires before the laser etching process. The maximum line width of lateral wires and maximum linear distance between adjacent lateral wires are predetermined to be less than specific differences involving wire dimensions and alignment deviations, ensuring that even with alignment errors, short circuits cannot occur. This pre-planned dimensional design enables the subsequent laser etching to proceed efficiently without compromising alignment accuracy.

The patent applies parameter changes by transforming the alignment deviation parameter from a problematic variable into a design input. The maximum line width of lateral wires and maximum linear distance between lateral wires are set based on the alignment deviation between first and second wirings. Specifically, these dimensions are defined to be less than the difference between wire spacing and alignment deviation, converting the reliability concern into a straightforward dimensional specification that simplifies the overall wire layout design.
