Image display device having keyboard and keyboard unit therefor

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.

1 . A keyboard unit attached to, detached from, stored in and withdrawn from any one image display device provided with a flexible display device that can be bent, rolled or expanded among an infolding image display device, an outfolding image display device, a dual-folding image display device implementing both infolding and outfolding, a rollable infolding image display device, and a rollable outfolding image display device, the keyboard unit comprising:
 a keyboard body having keys arranged on one side, and applying a configuration or a component corresponding to a configuration or a component applied to a keyboard application space of the image display device and related to attachment, detachment, storage and withdrawal of the keyboard unit; and   a camera unit including a rotatable camera module, and a supporting arm of a predetermined length, an end of which is assembled at one side of the keyboard body in a rotatable state, having a rotation support piece formed at an opposite end to rotate and support the camera module, wherein   the keyboard body includes, on one side, a camera module storage space formed to store and rotate the camera module without interference with individual keys of the keyboard body, and a supporting arm storage groove formed to store and maintain the supporting arm without interference with individual keys of the keyboard body.   
     
     
         2 . The unit according to  claim 1 , wherein the keyboard body includes a support slope surface formed at an end portion of the supporting arm storage groove to apply a contact sustaining force to the supporting arm so that the supporting arm rotating and protruding from the supporting arm storage groove may maintain a predetermined angle and a standing state without help of an external force. 
     
     
         3 . The unit according to  claim 1 , wherein the keyboard unit further comprising a supporting arm protrusion sensing means capable of sensing a stored or a rotating and protruding state of the supporting arm. 
     
     
         4 . The unit according to  claim 1 , wherein the keyboard unit further comprising a hand position sensing means for sensing a user's hand entering a camera module area under the camera module in a character input state or a user's hand moving from the camera module area under the camera module toward the keys capable of inputting characters provided, at one end portion of the keyboard body located on an opposite side of the camera module storage space. 
     
     
         5 . The unit according to  claim 1 , wherein the keyboard unit further comprising a charging means including a battery and a charging terminal. 
     
     
         6 . The unit according to  claim 1 , wherein a perimeter of an exposed edge of the image display device or out of the edge, in a perimeter of the keyboard unit, is formed by applying a protruding bumper or made of a soft material capable of absorbing shock so that the keyboard unit may absorb shock applied to the image display device while the keyboard unit is attached to or stored in the keyboard application space of the image display device. 
     
     
         7 . The unit according to  claim 1 , wherein a display device cover for covering an all-time screen display surface of the flexible display device is formed to be extended or assembled as a separate component at an edge of the keyboard unit. 
     
     
         8 . The unit according to  claim 1 , wherein the keyboard unit further comprising a display device cover for covering an outfolding screen display surface of the flexible display device, which is formed to be extended or assembled as a separate component at an edge of the keyboard unit. 
     
     
         9 . The keyboard unit according to  claim 8 , wherein an edge cover for covering a portion where outfolding of the flexible display device is generated is formed at one end of the display device cover. 
     
     
         10 . The unit according to  claims 8 , wherein a window is formed in the display device cover to confirm partial image information even when the display device cover covers the all-time screen display surface or the outfolding screen display surface of the flexible display device, or not to cover the camera module after the display device cover is opened.
