A display system configured to be integrated in an accessory to be worn by a wearer/user as an article of clothing, an item of jewelry, a wristwatch, a pocket watch or a fashion item, the display system including:
- (a) a source of electrical energy,
- (b) one or more light sources,
- (c) a source of mechanically generated information, the mechanically generated information being variable, wherein the system is adapted to indicate the mechanically generated information via an indication selected from one of the group of indications consisting of indication of mechanical information, indication of visual animation and indication of a visual presentation,
- (d) a transformation device adapted for transforming such mechanically generated information into luminous information or visual animation, and the source of electrical energy adapted to feed electrical energy to the one or more light sources indirectly via the transformation device,
- (e) a control device adapted to allow the user/wearer to control the activation of the system, wherein the system provides a luminous information or visual animation, and
- the source of electrical energy being
- a miniature generator actuated by the combination of the movements of the user/wearer and the effect of gravity on a mobile mass, or
- an energy source selected from one of the group of energy sources consisting of the user/wearer, a battery, an electrochemical device, a rechargeable battery, a solar/photovoltaic cell, and a micro-generator converting mechanical energy into electricity.
