AI Technical Summary
Technical Problem
During the fabrication of OLED touch display products, the metal traces of the photomask may experience voltage differences due to charge accumulation, resulting in pattern damage and affecting the yield and touch stability.
Method used
The design employs multiple light-shielding strips and short-circuit strips to short-circuit the wiring and extension parts of the mask, evenly distributing static charge and preventing damage from electrostatic discharge.
Benefits of technology
It improves product yield and touch stability, and reduces the risk of electrostatic discharge injury.

Abstract
本公开公开了一种掩模板、显示基板以及显示装置，其中本公开一实施例的掩模板包括多个遮光条和多个短路条，多个遮光条配置为阻挡光线，第一遮光条布置成网格状图案；第二遮光条包括位于网格状图案第一侧并延伸至第二侧的多个第一走线部，位于网格状图案第三侧并延伸至第二侧的多个第二走线部，以及位于网格状图案第二侧的多个第三走线部，第三走线部包括，靠近第一走线部的第一延伸部和靠近第二走线部的第二延伸部，多个短路条将第一走线部、第二走线部、第一延伸部和第二延伸部短接。本公开提供的掩模板通过将第一走线部、第二走线部、第一延伸部和第二延伸部短接，使得静电荷均匀分布在各条走线部，避免静电释放损伤。
