  • Patent number: 10878728
    Abstract: A flexible display apparatus includes a display panel including a first region, a second region, and a third region between the first region and the second region, a housing movably supporting the display panel, and a frame movably disposed in the housing to stretch or contract based on movement of the display panel, wherein the frame includes a fixing part fixed to the housing to movably support the first region of the display panel, a sliding part coupled to the second region of the display panel and movably disposed in the housing, and an elastic part elastically connected between the fixing part and the sliding part to support the third region of the display panel. Accordingly, a display area may be enlarged and reduced with only an action of a user's hand by using a frame without a separate driving power, and thus, total size and weight may decrease, thereby increasing the convenience of keeping and movement.
