Touch panel and touch type input device

摘要

A touch panel which includes a molecule oriented polylactic acid film, the polylactic acid film has a first principal plane and a second principal plane formed with electrodes, and the electrode on the first principal plane includes divided electrodes which are electrically divided into at least four sections. A touch panel input device having the touch panel is configured to have the respective divided electrodes connected to a processor which outputs position information and/or pressed information based on voltages detected independently from the divided electrodes.

1. A touch panel comprising:
a molecule oriented polylactic acid film, the polylactic acid film having a first principal plane and a second principal plane; a divided electrode on the first principal plane, the divided electrode being electrically divided into at least four sections; and an electrode on the second principal plane, wherein the polylactic acid film is configured to generate a voltage based on deformation of the polylactic acid film, and each of the sections of the divided electrode output respective voltages resulting from the deformation of the polylactic acid film so that position information of a pressing location of the touch panel is determined based on differences between the respective voltages output from each of the sections of the divided electrode.
