Abstract

Disclosed is a protective case for a foldable image display device, wherein the protective case, when in a folded state, has a cone-shaped folding space gap between the inner surfaces thereof that progressively narrows further from a fold occurring axis thereof. The present invention is provided with a protective case 1 and a protective case 2. The protective case 1 is provided with: a fixing surface 1 surrounding the folding outer surface 1; and a folding space protruding peripheral surface 1 which surrounds a portion of the peripheral surface of the foldable body and has a folding space sloped surface 1 further protruding a predetermined length in the direction of the folding space gap. The protective case 2 is provided with: a fixing surface 2 surrounding the folding outer surface 2; and a folding space protruding peripheral surface 2 which surrounds a portion of the peripheral surface of the foldable body and has a folding space sloped surface 2 further protruding a predetermined length in the direction of the folding space gap. The protruding heights of the first folding space protruding peripheral surface 1 and the second folding space protruding peripheral surface 2 gradually decrease with distance from the fold occurring axis. According to the present invention, hinge damage caused by the application of an external force exceeding an allowable range when the foldable image display device is folded, and scratches, nicks, encapsulation damage, or the like of a screen display surface caused by foreign matter entering the folding space gap formed at the sides of the folding inner surfaces can be prevented.

Abstract

Provided is a protective case for a foldable image display apparatus which prevents the hinge breakage due to an external force action exceeding the allowable range in the folded state of the foldable image display apparatus and prevents scratching, stabbing, and other damages of the screen display surface due to foreign substances introduced into the folding space gap formed inside the folding inner surface. The protective case primarily supports and disperses an external force even when an external force is applied to the hinge part in the folded state, and the protective case occupies and closes the folding space gap which is an empty space area.

Abstract

A folding space member of a foldable image display device is disclosed. The present invention is a member which is applied to prevent hinge damage due to an external force action beyond an allowable range when the foldable image display device is in a folded state, and to prevent scratches, nicks, damage to a plastic cover, etc., of a screen display surface caused by foreign matter flowing into a folding space gap formed on a side of an inner folding surface, wherein the member is realized in the form of an accessory detachable from the foldable image display device or may be integrally formed as a part of the foldable image display device, and even when the display device is in a folded state and the external force is applied to a hinge portion, a folding space insert and a folding space support serve to support and disperse the external force and close the folding space gap.

Abstract

The present invention relates to an image display device with multiple layers of display devices, the image display device comprising a fixed body, wherein the fixed body has one surface on which two types of display devices having different properties, such as a transparent display device and display device 1 including an electronic ink display device on the one surface of the fixed body, are laminated. The image display device comprises a light shutter which is electrically connected to a controller so as to perform the function of selectively blocking or transmitting a light inflow to display device 1 and a light outflow from display device 1.

Abstract

The present invention relates to an image display device comprising a transparent display device and an optical shutter. Unlike existing smartphones or tablet PCs which, when an image display device thereof is turned off or inactivated, maintain a screen of the image display device in a black color capable of providing no information to a user, when the disclosed image display device is turned off or inactivated, the image display device allows a still image (including a picture, a document, a sketch, a memo, etc.), which is applied by a user in a state where the still image can be replaced between the transparent display device and a front support surface of a fixed body, to pass through the optical shutter and the transparent display device maintaining a transparent state without consuming electricity and be then always displayed to the user. Further, when the disclosed image display device is turned on or activated, the image display device opacifies the optical shutter applied between the transparent display device and the still image applied by the user, so as to block exposure of the still image and allow only an activated screen of the transparent display device to be displayed to the user.

Abstract

The present invention relates to an image display device comprising a flexible display means that can be bent freely, such as a flexible OLED or electronic paper, wherein the flexible display means employs a folding type edge at one end thereof and employs a rolling type or sliding type edge using a roller at the other opposite end thereof. More specifically, the present invention relates to an image display device comprising a flexible display means which has an in-folding or out-folding function applied to an edge at one end thereof and a rolling function applied to an edge at the other opposite end thereof, wherein the edge to which the folding or rolling function is applied can freely achieve the folding or rolling function independently without being affected by the opposite edge to which the rolling or folding function is applied.
