Abstract
An opto-electronic device comprises light transmissive regions extending through it along a first axis to allow passage of light therethrough. The transmissive regions may be arranged along a plurality of transverse configuration axes. Emissive regions may lie between adjacent transmissive regions along a plurality of configuration axes to emit light from the device. Each transmissive region has a lateral closed boundary having a shape to alter at least one characteristic of a diffraction pattern exhibited when light is transmitted through the device to mitigate interference by such pattern. An opaque coating may comprise at least one aperture defining a corresponding transmissive region to preclude transmission of light therethrough other than through the transmissive region(s). The device can form a face of a user device having a body and housing a transceiver positioned to receive light along at least one light transmissive region.
