Abstract: A device comprising an optical system, a transmitter, and a detector. The optical system comprises a transmitter-side component and a detector-side component. The transmitter is adapted to transmit a first plurality of dots of light, along a transmitter-side optical path through at least one transmissive region of the transmitter-side component and beyond the device. The detector is adapted to detect a second plurality of dots of light from beyond the device and along a detector-side optical path through at least one transmissive region of the detector-side component. The transmitter-side component is adapted to impart a first diffraction effect, on the first plurality of dots, that introduces at least one nth order diffracted dot, each corresponding to one of the first plurality of dots. The detector-side component is adapted to impart a second diffraction effect on the second plurality of dots before detection by the detector.

Abstract: An opto-electronic device having a plurality of layers deposited on a substrate and extending in at least one lateral aspect defined by a lateral axis thereof, comprises at least one emissive region and a light-absorbing layer surrounding the at least one emissive region. The at least one emissive region comprises a first electrode, a second electrode, and at least one semiconducting layer disposed between the first electrode and the second electrode. The first electrode is disposed between the substrate and the at least one semiconducting layer. The light-absorbing layer reduces reflection of light incident thereon, and comprises at least one dielectric layer and at least one particle deposited with the at least one dielectric layer.

Abstract: The present disclosure relates to electronic devices having a display panel and a plurality of opto-electronic components, and in particular, mechanisms for mitigating diffraction effects when exchanging light, by such opto-electronic components, through at least one transmissive region of the display panel. The display panel may be one of: be, and comprise, a layered semiconductor device, which in some non-limiting examples, may be an opto-electronic device, having a plurality of (sub-) pixel emissive regions, each comprising first and second electrodes separated by at least one semiconducting layer.
