Flexible display device and method of sensing warpage of the same

摘要

A flexible display device includes: a flexible display unit configured to display an image; a flexible touch screen unit disposed over the flexible display unit; an insulating film interposed between the flexible display unit and the flexible touch screen unit, and a spacer formed between the flexible touch screen unit and the insulating film in order to maintain a distance between the flexible touch screen unit and the insulating film. A conductive layer is further formed over the insulating film and configured to touch the flexible touch screen unit when the flexible display device is bent. A degree of warpage of the flexible display device can be measured and thus can be utilized in various warpage events of the flexible display device by using warpage values.

1. A flexible display device comprising:
a flexible display unit configured to display an image; a flexible touch screen unit disposed over the flexible display unit, wherein the touch screen unit comprising a touch-sensitive surface that faces the flexible display unit; an insulating film interposed between the flexible display unit and the flexible touch screen unit; a conductive layer interposed between the insulating film and the flexible touch screen unit; and a spacer providing a gap between the flexible touch screen unit and the conductive layer such that the conductive layer does not contact the touch-sensitive surface of the flexible touch screen unit when the flexible display device is not bent, wherein the flexible display unit and the flexible touch screen unit are configured such that part of the conductive layer contacts the touch-sensitive surface when the flexible display device bends at a certain degree.
