Claim 13:
14. A method, comprising:
providing, using a control circuit, a binary control signal alternating between a first binary state during first phases and a second binary state during second phases;
emitting light, using a screen controlled by the binary control signal, during each first phase, and not emitting, using the screen, light during each second phase;
providing, using a light sensor disposed under the screen or along an edge of the screen, 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
determining, by a processing unit, a setpoint signal based on the measurement signal, a duration of the first binary state and the second binary state is set by the control circuit based on the setpoint signal.
