Abstract

Disclosed is a folding display device comprising: a display panel. and a folding shaft. The display play can be configured to be folded along the display device. The folding shaft can be configured to partition the display panel into a first display portion and a second display portion, and a folding state detecting electrode is a capacitive detecting electrode and is provided on the first display portion and/or the second display portion. According to the disclosure, the problem of the prior art that a detecting unit in a folding display device is difficult to determine the specific degree of folding of the folding display device may be solved. Thereby, the degree of folding of a folding display device can be accurately detected.
