Touch panel

摘要

In a touch panel, a rectangular resistive film is formed on a substrate and electrodes are provided along the four sides of the resistive film. Each electrode includes a plurality of gaps and a plurality of divided electrodes. The divided electrodes are linearly arranged along the corresponding side of the resistive film, and the electrode, in which the divided electrodes at both ends are connected to terminals, respectively, is formed by arranging the divided electrodes of the same shape and repeating this same shape.

1. A touch panel comprising:
two substrates opposing each other at a particular distance; resistive films formed on opposing surfaces of the substrates, respectively; and electrodes formed along four sides of one of the resistive films, each of the electrodes including a plurality of divided electrodes that are linearly arranged and resistances between the divided electrodes, the divided electrodes and the resistances being connected in series with each other, each of the divided electrodes being made pectinate and comprising a straight-shaped inner electrode portion and an outer electrode portion other than the straight-shaped inner electrode portion, configured such that
the straight-shaped inner electrode portion is disposed at a first distance from a respective one of the four sides of the one of the resistive films, the first distance being greater than a second distance at which the outer electrode portion is disposed from the respective one of the four sides,the straight-shaped inner electrode portions of the divided electrodes each extend parallel to the respective one of the four sides and are linearly arranged with respect to each other,lengths of the straight-shaped inner electrode portion in each of the divided electrodes other than the straight-shaped inner electrode portions of the divided electrodes at both ends of the electrode are substantially the same,a ratio of the length of each of the straight-shaped inner electrode portions of the divided electrodes at the both ends of the electrode to the length of each of the straight-shaped inner electrode portions of the other divided electrodes is from 0.1:1 to 0.5:1, andthe straight-shaped inner electrode portions of the divided electrodes at the both ends of the electrode are connected to respective power supply terminals.
