Classification: CPC G  H | IPC G  H

Claim 0:
1. An electronic device comprising:
a first housing;
a second housing connected to the first housing to be variable in relative position with respect to the first housing;
a display module including a flexible substrate, a thin film transistor (TFT) layer laminated on the flexible substrate, a protection layer laminated on the TFT layer, and a deformation region which deforms as the relative position of the second housing with respect to the first housing changes;
a bending portion including a first layer which is integrally configured with the flexible substrate and at least a part of which is bent to extend to a rear surface of the display module, and a second layer which is integrally configured with the TFT layer, at least a part of which is bent to extend to the rear surface of the display module, and which is laminated on the first layer;
a display driver IC (DDI) disposed in the bending portion;
a touch wire disposed on the protection layer to be connected to a touch circuit of the electronic device; and
a detection wire disposed on the protection layer in the deformation region and configured to have an electrical value changeable depending on physical damage to the protection layer,
wherein the detection wire extends from the protection layer to the second layer of the bending portion so as to be electrically connected to the display driver IC, and
wherein the display driver IC includes a detection circuit electrically connected to the detection wire to detect the electrical value of the detection wire, which changes due to the physical damage to the protection layer.
