Foldable electronic device and control method thereof

An electronic device comprising:

• a first housing including a first top face facing a first direction, and a first bottom face facing a second direction opposite to the first direction in a second state;
• a second housing including a second top face facing a third direction, and a second bottom face facing a fourth direction opposite to the third direction in the second state;
• a touch screen display continuously disposed between the first top face of the first housing and the first bottom face of the first housing and between the second top face of the second housing and the second bottom face of the second housing, the touch screen display being viewable through at least the first top face and the second top face, wherein the touch screen display includes a flat region, at least one curved region, and a folding region;
• a connection structure comprising hinges configured to pivotably connect the first housing and the second housing, wherein the first housing is configured to be folded with respect to the second housing using the hinges, the connection structure comprising hinges comprising a first hinge and a second hinge provided proximate different respective sides of the connection structure, the second hinge being spaced apart from the first hinge in direction of a folding axis;
• the connection structure further comprising hinge covers disposed over the hinges in direction of a rotation axis of the hinge, and configured to cover the hinges when the hinges are viewed from outside of the electronic device;
• and
• support sheets disposed between the first hinge and the second hinge and disposed under the folding region to prevent or reduce the folding region of the touch screen display from deflection by a user touch on the folding region,
• wherein the folding region and the flat region of the touch screen display form one planar display area in a first state where the first top face is parallel to the second top face,
• wherein the folding region in the second state distinct from the first state forms a curved display area extended from the flat region.
