Display device of the galvanometric or logometric type, including a control circuit in form of an integrated circuit chip

A display device with a winding a pivoting element of the galvanometic or logometric type, comprising:

• a case,
• a support of electrically insulating material fixed with said case,
• at least one integrated circuit chip serving as a control circuit for said display device, said integrated circuit chip being carried by said support,
• a memory included in said integrated circuit chip, said memory defining a parameter connected by a transformation law from size of input electrical control to angle of pivoting of said pivoting element of said device, so that all the display devices produce the same angle of pivoting of the pivoting element when receiving the same electric control signal at the input, even if said display devices have different transformation laws from size of input electric control to pivot angle of the pivoting element, as a result of manufacturing spread, and
• a series of strips of electrically conductive material carried by said support, said series of strips comprising first strips which connect said integrated circuit chip and at least one said winding of said device, and said series of strips comprising further strips which have each a first end connected to said integrated circuit chip and have each a second end provided with a curve, on an edge of said support, for establishing electric contact between said strips of electrically conductive material and external circuits generating electric control signals.
