This disclosure concerns printed wiring boards for recording or displaying information. The printed wiring board comprises an insulated substrate, a plurality of functional elements placed on the insulated substrate, a plurality of strip wires formed on the insulated substrate, each of the strip wires connected to a respective functional element, and at least two of the strip wires having different lengths such that one is longer than the other, each of the strip wires comprising a first portion having a first resistivity and a second portion having a second resistivity which is higher than the first resistivity, wherein the resistance of the second portion of the shorter strip wire is higher than the resistance of the second portion of the longer strip wire. |
