图5为本申请的显示面板的第三实施例的结构示意图(图中仅示出单一第二触控电极的部分)。
本发明的实施方式
请参照附图中的图式,其中相同的组件符号代表相同的组件。以下的说明是基于所例示的本申请具体实施例,其不应被视为限制本申请未在此详述的其它具体实施例。
请参照图2和图3,图2为本申请的显示面板的第一实施例的调光结构层、金属网格层和架桥的结构示意图;图3为本申请的显示面板的第一实施例的结构示意图(图中仅示出单一第二触控电极的部分)。
本申请的第一实施例的显示面板100包括封装层11和形成在封装层11上的触控功能结构12。触控功能结构12包括保护层121、金属网格层122、调光结构层123、绝缘层124和架桥125。
保护层121设置在封装层11上,用于保护封装层11。金属网格层122设置在封装层11上。调光结构层123设置在封装层11上。具体的,在第一实施例中,金属网格层122和调光结构层123均设置在保护层121上,绝缘层124覆盖金属网格层122和调光结构层123。
金属网格层122包括沿着第一方向延伸设置的多条第一金属走线1221和沿着第二方向延伸设置的多条第二金属走线1222。第一金属走线1221和第二金属走线1222交叉设置形成多个空余区域122a。调光结构层123包括多个用于调节显示面板100发出光线的出光效果的微结构1231。
微结构1231于封装层11上的正投影位于空余区域122a于封装层11上的正投影内。在本第一实施例中,具体的,微结构1231和金属网格层122间隔设置且微结构1231设置在空余区域122a中。
本第一实施例的显示面板100通过调光结构层123的微结构1231对显示面板100的出光进行调整,从而使得显示面板100的出光更为均匀且出光效率更大。其中,微结构1231可以通过调节自身的尺寸、形状和排列阵型,以调整显示面板100的出光效率。
另外,微结构1231的调光原理是通过改变发出光的光折射角度和光反射角度,进而影响光线的传播方向,进而起到调整出光效率的目的。
在本第一实施例中,将调光结构层123和金属网格层122同层设置,避免了发出光线经调光结构层123的微结构1231的调整后,部分光线被金属网格层122挡住,提高了出光效果。
在本第一实施例中,第一方向和第二方向相互正交设置。当然,第一方向和第二方向也可以非正交设置,本申请并不限制。
在本第一实施例中,微结构1231呈阵列式排布。这样的设置提高微结构1231布置的均衡性,进而提高出光效果。当然,在微结构1231在进行阵型排列时,可以根据具体的情况进行设置,比如需要蓝色光更亮,则在蓝色子像素的上方设置微结构;如需要提高显示面板四周边缘的亮度,则可以在显示面板的四周边缘区域设置微结构或密度相较于中间区域更大的微结构。
另外,微结构1231包括透光的金属体、二维光子晶体和微透镜中的至少一种。即微结构1231可以是单一金属体、二维光子晶体和微透明,也可以包括金属体、二维光子晶体和微透明中的两种或三种。
可选的,二维光子晶体包括SiN x晶体和/或SiO 2晶体,微透镜包括球面透镜和/或非球面透镜。即二维光子晶体可以是单一的SiN x晶体和SiO 2晶体,也可以包括SiN x晶体和SiO 2晶体两种。微透镜可以是单一的球面透镜和非球面透镜,也可以包括球面透镜和非球面透镜两种。
进一步的,至少部分微结构1231的出光面为凹凸形的曲面,比如锯齿状、波浪状等。这样的设置,提高了出光的均匀性和扩大出光角度,而且由于微结构1231的凹凸曲面结构,提高了微结构1231和绝缘层124的粘结稳定性。
而当本申请的显示面板为柔性显示面板时,微结构1231的凹凸曲面起到释放弯折应力的作用,便于柔性显示面板进行弯折。
在本第一实施例中,金属网格层122的金属走线(第一金属走线1221和第二金属走线1222)围成多个触控电极,多个触控电极包括多个交叉且相互绝缘设置的第一触控电极12a和第二触控电极12b。
其中相邻的两个第二触控电极12b通过架桥125电性连接,相邻的两个第一触控电极12a通过走线直接连接。
触控功能结构12还包括有机层126,架桥125设置在绝缘层124上,有机层126设置在是架桥125上。当然,在另一实施例中,架桥可以设置在封装层上,保护层设置在架桥上,金属网格层和调光结构层设置在保护层上,绝缘层设置在金属网格层和调光结构层上。
另外,架桥125于封装层11上的正投影和微结构1231于封装层11上的正投影间隔设置。这样的设置,避免了发出光线经调光结构层123的微结构1231的调整后,部分光线被架桥125正面挡住,提高了出光效果。
请参照图4,在第二实施例的显示面板200中,显示面板200包括封装层21和形成在封装层21上的触控功能结构22。触控功能结构22包括保护层221、金属网格层222、调光结构层223、绝缘层224和架桥225。
本第二实施例与第一实施例的不同之处在于:触控功能结构22包括一绝缘层224,调光结构层223设置在保护层221上,绝缘层224设置在调光结构层223上,金属网格层222设置在绝缘层224上,微结构2231对应设置在空余区域的下方。架桥225和调光结构层223同层设置,架桥225用于连接金属网格层222中的两个相邻的第二触控电极。
另外,本第二实施例中的调光结构层223的结构和第一实施例的调光结构层的结构一致,具体请参照第一实施例的内容,在此不再赘述。
