Flexible display apparatus

A flexible display apparatus comprising:

• a flexible display module;
• a frame module connected to a lower side of the flexible display module, the flexible display module being configured to be wound onto the frame module or unwound from the frame module;
• and
• a panel elevating module connected to an upper side of the flexible display module, the panel elevating module including at least one retractable unit configured to elevate the flexible display module via unfolding of the at least one retractable unit,
• wherein the retractable unit includes:
• a plurality of first links;
• a plurality of second links intersecting respective ones of the first links;
• a hinge member provided at each intersection between the first and second links;
• a joint member provided at adjoining ends of each of the first and second links;
• and
• an elastic member provided at each joint member and supported by the ends of the first and second links,
• wherein the elastic member is compressed when the flexible display module is moved downward,
• wherein the elastic member provides the respective first and second links with a restoration force when the flexible display module is moved upward,
• wherein the panel elevating module further includes:
• an upper frame coupled to the upper side of the flexible display module to support an upper side of the retractable unit;
• a lower frame coupled to the frame module to support a lower side of the retractable unit;
• and
• a link elevating unit coupled to the lower frame to fold and unfold the retractable unit, and
• wherein the link elevating unit includes a cylinder member having an elevating shaft connected to the hinge member located adjacent to the lower frame.
