Touch panel system, electronic device, and semiconductor device

An electronic device comprising:

• a first housing;
• a second housing;
• a third housing;
• a plurality of hinges,
• a first circuit;
• a display portion;
• and
• a touch sensor,
• wherein the first circuit comprises a neural network,
• wherein the display portion comprises a flexible display,
• wherein the flexible display comprises a portion held by the first housing, a portion held by the second housing, and a portion held by the third housing,
• wherein the touch sensor is configured to output an input handwritten character as image information to the first circuit,
• wherein the first circuit is configured to analyze the image information and convert the image information into character information, and configured to display an image comprising the character information on the display portion,
• wherein the analysis is performed by inference through the use of the neural network, and
• wherein the first housing, the second housing, and the third housing are joined by the plurality of hinges so that the flexible display is changed in shape reversibly between an opened state and a three-folded state.
