The protective case of the present inventors foldable image display device presented below is a foldable image display device or folder in which two out-folding and folding generation axes 11 and 12 are applied at a central part of the foldable body 20 while maintaining an interval. A foldable image display device having a feature that a single out-folding folding generation shaft 11 is applied to the body 20 and in the folded state, the outer circumferential surface of one foldable body is received and protected by the protruding portion of the opposite foldable body. It is a protective case applied to and can be applied to the existing out-folding imaging device.

It is a perspective view, a front view, a bottom view, a side view, and a rear view of the folded state, and FIG. 3 is a front view and a bottom view of the fully flat unfolded state of FIGS. 1 and 2.

As shown in FIGS. 1 and 3, the foldable image display device 10 capable of double-out-folding has an out-folding-folding axis 1 (11) and an out-folding-folding generation axis 2 at the center of the foldable body 20. (12) applies with a certain interval.

As shown in the perspective view and rear view of Fig. 1, the double-out-folding image display device has both sides of the foldable body parallel to the axis 1 (11) and out-folding generation axis 2 (12) when the image display device is fully folded. The end edge maintains a gap that can be opened and operated without mutual interference, and the bezel portion of the foldable body 20 except for the flexible display device 60 is narrow.

Due to the characteristics of the double-out-folding image display device, the display device 60 and flexible display device 60 are fixed or detachably applied to the edge of the foldable body opposite the axis 1 (11) where the out-folding occurs or the axis 2 (12) where the out-folding occurs. It is difficult to apply a protective case that protects the outer circumferential surface of the foldable body 20.

When the protective case is fixed to the circumferential surface, the position of the unfixed part of the protective case may be changed due to the change in the circumference of the circumferential surface that occurs when the foldable body is folded or unfolded. When the sphere 130 is applied to the protective case, a problem in that the portion of the flexible display device 60 displayed through the transmission window or the through hole 130 may be hidden due to the transition to the unfolded state may occur.

In addition, as shown in FIGS. 1 to 3, when predicting a case where the user grips the foldable image display device, which one faces the axis 1 (11) where the out-folding occurs or the axis 2 (12) where the out-folding occurs? It is highly likely to be used while gripping the outer circumference of U.

Under such a grip condition, one side of the protective case is fixed to the outer circumference of U and rotates or folds when one facing the shaft 1 (11) or the shaft 2 (12) where the out-folding occurs. The part of the protective case that is used may interfere with the user's hand that maintains the grip state, resulting in jamming.
