参见图5，所述光敏器件44包括至少一个薄膜晶体管442、第一绝缘层443和光敏二极管444。
所述至少一个薄膜晶体管442位于所述基板45上。在实际中，所述薄膜晶体管442和所述基板45还包括缓冲层。由于在所述基板朝向所述发光层30的一侧设置了第一遮光薄膜445，因此所述第一遮光薄膜445能够有效的遮挡住发光层30的光线，避免所述光线进入所述薄膜晶体管442和光敏二极管444中。一方面能够避免薄膜晶体管442中的有源区受光照影响二产生的阈值电压漂移，另一方面能够避免发光层30的光线干扰光敏二极管444，使光敏器件作出错误的判断。
所述第一绝缘层443覆盖所述至少一个薄膜晶体管442，用于隔离所述薄膜晶体管442和光敏二极管444。所述光敏二极管444设置在所述第一绝缘层443上，通过通孔与所述至少一个薄膜晶体管442电连接。所述光敏二极管444在所述基板45上的投影与所述至少一个薄膜晶体管442在所述基板45上的投影不重叠。这样设置能够有效的避免薄膜晶体管442中的金属走线和其他不透光区遮挡所述光敏二极管444。
在本实施例中，所述光敏二极管444包括：第一电极4441、第二绝缘层4444、光敏材料4442和第二电极4443。
所述第一电极4441位于所述第一绝缘层443上，通过通孔与所述至少一个薄膜晶体管442电连接。所述第二绝缘层4444覆盖所述第一电极4441，并具有暴露出所述第一电极4441的开口。所述光敏材料4442位于所述开口中。所述第二电极4443覆盖所述光敏材料4442。
本实施例中，所述第一电极4441为透光电极，所述第二电极4443为反射电极。所述反射电极可以是金属电极，例如银、铜、金等具有良好的导电性和反射率的导电金属。所述透明电极可以是氧化铟锡等透明导电材料。所述第一遮光薄膜445覆盖所述第二电极4443。
本实施例中，所述彩膜层40还包括第二遮光薄膜445，所述第二遮光薄膜445设置在所述基板45背离所述发光层30的表面上。所述第二遮光薄膜445在所述基板45上的投影覆盖所述至少一个薄膜晶体管442在所述基板45上的投影，且所述第二遮光薄膜445在所述基板45上的投影与所述光敏二极管444在所述基板45上的投影不重叠。所述第二遮光薄膜445用于遮挡外界光线，避免外界光线进入薄膜晶体管442中而损害的薄膜晶体管442的性能。
本申请中，所述显示面板还包括与所述彩膜层40连接的柔性电路板，所述柔性电路板将感光区产生的电信号传输给控制芯片。柔性电路板的设置为本领域中的常用技术手段，在此不再赘述。
相应的，本申请还提供了一种电子设备，所述电子设备包括如前所述的显示面板。
本申请将光敏器件设置在彩膜层中，与彩膜层中的彩色滤光片间隔设置，从而达到了将光敏器件集成到显示面板中的目的，避免了现有技术中由于设置光敏单元而导致的成本增加，能够有效减小电子设备的厚度。相比于现有技术，本发明对集成有指纹识别功能的智能设备进行优化，在不影响电子设备的性能的情况下有效降低了成本。
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。
