1. A system comprising:
a control circuit configured to provide a binary control signal alternating between a first binary state during first phases and a second binary state during second phases;
a screen controlled by the binary control signal, the screen being configured to emit light during each first phase, and not emit light during each second phase;
a light sensor disposed under the screen or along an edge of the screen, the light sensor configured to provide a measurement signal after a plurality of consecutive measurements across a plurality of consecutive second phases, each measurement being a representative of a quantity of light received by the light sensor during each measurement phase; and
