1. A system for displaying information, comprising:
 an emission device arranged to emit light so as to display information to a user, the emission device being adapted to emit the light in a pulsed manner so that the intensity of the light varies between a high value and a low value; and
 a selective viewing device comprising a panel, the panel being adapted so that the user can view the light which is emitted by the emission device through the panel so as to visually perceive the information being displayed, the panel having a variable transparency which can be varied between a state of high transparency and a state of low transparency,
wherein the system is adapted to synchronize the emission device and the selective viewing device so that the states of the emission device emitting light at a high-intensity value and the states of the panel of the selective viewing device of high transparency overlap in time,
the system further comprising:
 a photoelectric conversion means arranged to convert ambient light into electric energy which is fed into the system; and
 an energy storage device arranged to supply energy to drive the emission device, such that the energy produced by the photoelectric conversion means is used to store energy in the energy storage device, and
wherein the energy storage device comprises at least a first energy storage component and a second energy storage component, and the system is arranged so that one of the first energy storage component and the second energy storage components is charged by the photoelectric conversion means while the respective other of the first energy storage component and the second energy storage component supplies the energy to drive the emission device.
