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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) A display device according to claim 1, in which said display member (21) is of the liquid crystal display (LCD) type. ### Claim 3 (depends on 1) A display device according to claim 1, in which said display member (21) includes bistable nematic crystals. ### Claim 4 (depends on 1) A display device according to claim 1, in which said display device (20) forms part of a dose indicator or counter for a fluid dispenser device. ### Claim 5 (depends on 1) A fluid dispenser device comprising: a body (1); a fluid reservoir (10); a dispenser member (15), and a dose counter for counting the number of doses that have been dispensed or that remain to be dispensed from the reservoir (10), said device being characterized in that said dose counter includes a display device (20) according to claim 1. ### Claim 6 (depends on 5) A dispenser device according to claim 5, in which the interaction between two portions (10, 11; 1, 2) of said device moving relative to each other while the device is being actuated, is transformed by an electromechanical converter into an electric pulse used to change the display. ### Claim 7 (depends on 5) A dispenser device according to claim 5, in which the electric pulse required to change the display is created by a striker pin (11) that is displaced against a contactor (2) while the dispenser device is being actuated. ### Claim 8 (depends on 7) A dispenser device according to claim 7, in which said contactor (2) is held stationary relative to the body (1), and said striker pin (11) co-operates with a spring (12). ### Claim 9 (depends on 1) The display device according to claim 1, wherein the energy required to change the display is created by friction. ### Claim 10 (depends on 1) The display device according to claim 1, wherein the energy required to change the display is created by impact. ### Claim 11 (depends on 5) The dispenser device according to claim 5, wherein the dispenser member is a pump or a valve. ### Claim 12 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. ### Claim 13 (depends on 12) The display according to claim 12, wherein the electrical energy required to change the display is generated without a battery. ### Claim 14 (depends on 12) The display according to claim 12, wherein the display is a liquid crystal display (LCD). ### Claim 15 (depends on 12) The display according to claim 12, wherein the display comprises bistable nematic crystals.
