View Patent ↗The present invention relates to a variable display area type display device having a structure which can selectively extend or reduce a display area. The present invention comprises: a base plate having a foldable body; a display unit which is installed on one surface of the base plate and in which the display area is folded and changed by the folding of the base plate; and a plate supporting member for supporting the base plate before or after the folding of the base plate.
1. A variable display area type display device, comprising:
a base plate having a foldable body;
a display part which is installed at one surface of the base plate and has a display area which varies as the display area is folded and changed by the folding of the base plate;
a plate support member which supports the base plate before or after the base plate is folded;
wherein said base plate comprises a hinge part and a pair of plate unites which are coupled with each other in a foldable way about the hinge part; and
wherein said plate support member comprises a support part corresponding to a plane portion of the base plate and a guide part which is provided at an edge portion of each of both sides of the support part and has a guide groove guiding the edge portion of each of both sides of the base plate.
2. A variable display area type display device according to claim 1 , wherein said display part is formed of a flexible display which is entirely attached to the pair of the plate units.
3. A variable display area type display device according to claim 1 , wherein said display part is formed of a pair of displays attached corresponding to the pair of the plate units, respectively.
4. A variable display area type display device according to claim 1 , wherein in a state that the base plate is folded, an edge portion of each of both sides of one plate unit between the pair of the plate units keeps being guided by means of the guide part.
5. A variable display area type display device according to claim 4 , wherein at an end portion of one plate unit, there is provided a pivot member for providing a rotation center for an inverted operation of one plate unit while at the same time preventing the base plate from escaping from the plate support member.
6. A variable display area type display device according to claim 4 , wherein said base plate and said plate support member are formed in rectangular shapes, and the entire length of the base plate is two times the length of the plate support member.
