Abstract
Configurations for display stacks of an electronic device and methods for mitigating crosstalk are disclosed. The display stack may include a transceiver module, which may be located under or behind the display. The transceiver module may include a transmitter module, which may provide polarized light from the transmitter that may suppress module crosstalk. The transceiver module also may include a receiver module, which may include polarization control elements and an analyzer for differentiating between a target signal and a crosstalk signal. The polarization control on both the transmitter module and receiver module sides may suppress the crosstalk signals, which may be due to the reflections between and within the elements of the display stack and resulting from positioning the transceiver module behind the display.
