Data processing device

A data processing device comprising:

• a display portion comprising flexibility;
• a touch sensor comprising a first conductive layer;
• a first driver, a second driver and a third driver arranged in a periphery of the display portion;
• a sensor portion configured to discern an external state of the display portion;
• an arithmetic portion configured to supply image data to the first driver, the second driver and the third driver;
• and
• a memory portion configured to store a program executed by the arithmetic portion,
• wherein the first conductive layer is electrically connected to a second conductive layer via a conductive particle,
• wherein the first conductive layer is a conductive layer having a light-transmitting property,
• wherein the second conductive layer is a metal layer,
• wherein the display portion is configured to be folded at a first fold between the first driver and the second driver and a second fold between the second driver and the third driver,
• wherein a first mode in which the display portion is unfolded or a second mode in which the display portion is folded is sensed by the sensor portion,
• wherein when the display portion is folded, a first region of the display portion is unexposed and a second region of the display portion is exposed,
• wherein low power consumption processing is performed on the first region of the display portion, and
• wherein degradation correction processing is performed by controlling amount of current flowing through one of the first region and the second region of the display portion to inhibit display unevenness.
