掩膜组件、主掩膜板及配合掩膜板
摘要：
本发明涉及一种主掩膜板、配合掩膜板及掩膜组件，该掩膜组件包括具有蒸镀区的主掩膜板，具有配合区的配合掩膜板，主掩膜板的有效蒸镀区与显示面板的显示区对应，配合掩膜板的第一配合区内布设有第一配合开口，第一配合开口在配合掩膜板上的正投影完全覆盖有效蒸镀开口在配合掩膜板上的正投影，且配合掩膜板的第二配合区遮挡主掩膜板无效蒸镀区内的无效蒸镀开口。上述掩膜组件中，主掩膜板上在异形的有效蒸镀区外开设无效蒸镀开口，可以平均有效蒸镀区边缘的应力，防止有效蒸镀区边缘因为受力不均而产生褶皱，提高蒸镀良率。同时，可以通过配合掩膜板上的第二配合区遮挡无效蒸镀区内的无效蒸镀开口，制得具有开槽区的异形显示面板。
摘要（英）：

A mask component (100), comprising a main mask plate (10) provided with an evaporation plating zone (12) and a matching mask plate (30) provided with a matching zone, wherein an effective evaporation plating zone (121) of the main mask plate (10) corresponds to a display zone of a display panel; a first matching opening is formed inside a first matching zone (321) of the matching mask plate (30); the orthographic projection of an effective evaporation plating opening on the matching mask plate (30) is completely covered by the orthographic projection of the first matching opening on the matching mask plate (30); in addition, an ineffective evaporation plating opening (122) inside an ineffective evaporation plating zone (1123) of the main mask plate (10) is shielded by a second matching zone (323) of the matching mask plate (30). Also provided are the main mask plate (10) and the matching mask plate (30).
