    • The underside of an inactive portion of a display cover layer in an electronic device may be covered with an opaque masking material. Openings in the opaque masking material may be form ambient light sensor and proximity sensor windows. An ambient light sensor window may be filled with a material that transmits at least some visible light. A proximity sensor window may be filled with a material that transmits more infrared light relative to visible light than the material in the ambient light sensor window. The materials in the ambient light sensor window and proximity sensor window may include one or more layers of ink, patterns of holes, layers of material that are shared with the opaque masking layer, and materials that are black, white, or other colors. A light guide structure may be used to route light received from a sensor window to an associated sensor.
    • 电子设备中的显示覆盖层的不活动部分的下侧可以用不透明的掩模材料覆盖。 不透明掩模材料中的开口可以形成环境光传感器和接近传感器窗口。 环境光传感器窗口可以填充有透射至少一些可见光的材料。 接近传感器窗口可以填充相对于可见光透射比环境光传感器窗口中的材料更多的红外光的材料。 环境光传感器窗口和接近传感器窗口中的材料可以包括与不透明掩模层共享的一层或多层墨水,孔图案,材料层,以及黑色,白色或其它颜色的材料。 光导结构可以用于将从传感器窗口接收的光路由到相关传感器。
