本申请实施例提供一种显示面板,该显示面板包括基底、触控功能层和阵列功能层;所述基底包括第一基底层以及形成于所述第一基底层之上的第二基底层,所述阵列功能层设置在所述基底上,其中,至少一层触控功能层形成于所述第一基底层与所述第二基底层之间;通过将触控功能层设置在第一基底层和第二基底层之间,实现了显示面板的内嵌触控,同时对不同结构的触控功能层,可将其中一层触控功能层设置在第一基底层和第二基底层之间,另一层设置在第一基底层下或者第二基底层上,实现内嵌触控,对于单层结构的触控功能层,可使显示面板更加轻薄;通过在触控功能层上设置定位板,使得所述第二基底层的外露区能准确设置在所述触控功能层连接端,还可以作为后续基底表面阵列层制作的对位标记;通过将所述第二基底层的外露区尺寸设置的比所述阵列功能层的过孔尺寸大,使得所述第二基底层更容易形成,简化了制作工艺难度;通过将触控功能层上相对于子像素发光部件的区域挖空,使得触控功能层金属可以采用不透明金属;通过上述实施例,本申请实施例实现了显示面板的内嵌触控,使触控显示器更加轻薄。
综上所述,虽然本申请已以优选实施例揭露如上,但上述优选实施例并非用以限制本申请,本领域的普通技术人员,在不脱离本申请的精神和范围内,均可作各种更动与润饰,因此本申请的保护范围以权利要求界定的范围为准。
