Abstract
An electronic display device (20) including a display member (21). The display member (21) is permanent so that no energy is required to keep the display unchanged. The display device (20) operates without a battery, the energy required to change the display being created by interaction between two elements, such as by friction or by an impact, thereby creating an electric pulse that is processed by an electronic circuit (25) before being applied to the display member (21) in order to change its display.
Claims15
An electronic display device (20) including a display member (21), said device being characterized in that said display member (21) is permanent so that no energy is required to keep the display unchanged, said display device (20) operating without a battery, the energy required to change the display being created by interaction between two elements, thereby creating an electric pulse, said pulse being processed by an electronic circuit (25) before being applied to the display member (21) in order to change the display.
An electronic display device comprising a permanent display member that does not require energy to keep the display unchanged and that requires electrical energy to change the display;
- and
- wherein the electrical energy required to change the display is generated by interaction between two physical portions of the device moving relative to each other.
