本实施例中,遮挡条202的外周朝上凸设有围合壁300,围合壁300呈封闭围合状,围合壁300与遮挡条202围合形成开口朝上的容置腔301,围合壁300围合在镂空槽201的外周。通过设置围合壁300,这样,在喷涂透明胶体、第一荧光胶以及第二荧光胶的过程中,喷涂在遮挡条202上的透明胶体、第一荧光胶以及第二荧光胶则收纳的容置腔301中,避免在不同喷涂的过程中,残留物质与正在喷涂的物质之间形成混杂。
围合壁300为弹性材料制成,围合壁300具有朝向镂空槽201的侧边壁,侧边壁的中部朝向容置腔301弯曲凸出,形成凸入在容置腔301中的凸出部302,凸出部302弯曲围合形成朝向镂空槽201的凹陷空间303。
这样,在喷涂的过程中,喷涂的物质(例如透明胶体、第一荧光胶以及第二荧光胶)则会进入容置腔301中,且同时也通过镂空槽201喷涂在基板100的发光区102上,进入容置腔301中的喷涂物资朝外挤压凸出部302,在挤压的过程中,使得凹陷空间303变形,这样,处于围合壁300外部的喷涂物质,受到凸出部302的挤压,可以加快其通过镂空槽201,落入在发光区102上,避免在喷涂过程中,出现喷涂不实的问题。
本实施例中,凸出部302具有朝向布置的朝上部,朝上部设有多个开口朝上布置的孔位。这样,在喷涂的过程中,喷涂物质朝下冲入容置腔301中,也冲击着孔位,便于凸出部302受到更大的冲击,可以更好驱动凸出部302背离容置腔301弹性变形,从而可以挤压着镂空槽201上方的喷涂物质更密实、更快穿过镂空槽201,覆盖在发光区102上。
凸出部302的中部凸设有硬质的筋条400,筋条400延伸容置腔301的长度方向延伸布置,筋条400具有朝上布置的上表面,筋条400的上表面设有多个开口朝上布置的上凹槽401。这样,喷涂物质进入容置腔301后,自上而下冲击着筋条400,且上凹槽401可以加大喷涂物质的冲击,从而可以更好的驱动凸出部302弹性变形。
本实施例中,筋条400具有朝下布置的下表面,筋条400的下表面与凸出部302的相交处形成相交位,相交位沿着筋条400的长度方向延伸布置,相交位朝上凹陷,形成下凹槽条402,下凹槽条402沿着筋条400的长度方向延伸布置。
这样,通过设置下凹槽条402,减低筋条400的下表面与凸出部302之间连接的相交位的抗弯能力,在对筋条400进行冲击的情况下,通过筋条400可以更好驱动凸出部302背离容置腔301变形。
本实施例中,遮挡条202具有朝向镂空槽201的内侧壁,沿着自上而下的延伸方向,遮挡条202的内侧壁朝向镂空槽201倾斜布置。这样,在喷涂的过程中,穿过镂空槽201的喷涂物质则会朝内倾斜喷涂,避免喷涂物质越过镂空槽201的区域,喷涂至遮挡条202下方的区域,进一步限制了第一荧光胶与第二荧光胶之间的混杂。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本发明的保护范围之内。
