Abstract

A display screen (12A) includes a carrier (18), OLED pixels (14) disposed over the carrier (18), and control circuitry (16) disposed over the carrier (18) and coupled to the OLED pixels (14). The display screen (12A) also includes a light absorption layer (100) disposed in a plane such that the carrier (18) is on a first side of the plane, and the OLED pixels (14) and control circuitry (16) are on a second side of the plane. In some implementations, the light absorption layer (100) helps prevent light (40) emitted by an optical sensor module (10) disposed behind the OLED display screen (12A) from directly impinging on light sensitive regions of the display screeds control circuitry (16). The light absorption layer (100) also can, in some instances, help prevent light (42) from directly impinging on, and being reflected by, regions of the display screeds pixels (14).
