Benefits of technology

The solution enables portable productivity with keyboard and mouse input capabilities, protects the screen display surface, and enhances durability through shock absorption, addressing the limitations of conventional devices.

Problems solved by technology

However, although conventional shape-invariant plate-shape smart phones are convenient to use image information, they are inconvenient to be used as a productivity tool since keyboard input and mouse input are limited unlike the desktop or notebook computers.
Similarly, although shape-invariant tablet devices of a plate shape also have difficulties in keyboard input and mouse input, some problems of the keyboard input have been solved as two-in-one products having a detachable cover applying a keyboard function on one side which covers the screen display surface of the tablet device are released.
However, the problems such as inconvenience of portability that cannot be gripped with one hand, occurrence of keyboard contact scratches on the screen display surface, and limited use of a mouse input device that is important as a productivity tool have not been solved yet.
Although notebook computers widely used in the present are evaluated as a productivity tool that can be carried within a limited range as a keyboard is provided on one side of a folding surface, it does not satisfy high-level portability such as one-hand grip due to the limitation of shape invariant.
In addition, an image display device to which a flexible display device that can be folded and rolled will be applied needs to protect the screen display surface, in addition to the folding or rolling occurrence area that is a vulnerable portion of the flexible display device, from scratches or dents, and therefore, unlike the plate-shape smartphones and tablet computers, it inevitably requires to provide a cover case in the image display device itself, or customers need to purchase and apply a cover case later as an additionally applied product.

Abstract

The present invention relates to a foldable image display device or a foldable and rollable composite application image display device, which has a flexible display device capable of meeting requirements for a large screen and portability. The image display device having a keyboard is configured such that in a minimized state of the image display device, an attachable / detachable keyboard unit is mounted on the body of the image display device so that the attachable / detachable keyboard unit can be carried as a single piece with the image display device, and in a partially unfolded or wholly unfolded state of the image display device, the keyboard unit is detached to function as a keyboard, where a camera unit applied to the keyboard unit recognizes a user's one-handed gesture, such that it is possible for a user to perform tasks with the device even in the absence of a mouse.
