Abstract: A display device includes: a display panel, a back cover which supports the display panel on a rear surface of the display panel; at least one flexible film which is electrically connected to one end of the display panel and is on one surface of the back cover; a printed circuit board which is electrically connected to the at least one flexible film and on one surface of the back cover; and a roller on which the display panel and the back cover are wound or unwound, the roller being configured by a first flat portion, a second flat portion, and a curved portion. When the display panel and the back cover are fully wound around the roller, the at least one flexible film corresponds to the first flat portion, and the printed circuit board corresponds to the second flat portion.

Abstract: A display device may include a display panel, a first back cover disposed on a rear surface of the display panel, at least one flexible film which is electrically connected to one end of the display panel and is bent toward a rear surface of the first back cover or a front surface of the display panel, and a printed circuit board which is electrically connected to the at least one flexible film and disposed on the rear surface of the first back cover or the at least one flexible film. The printed circuit board overlaps one end of the display panel. Accordingly, one end of the display panel in which the pad area which is vulnerable to the stress is disposed and the printed circuit board are maintained to be flat, to minimize the damage of the display device.

Abstract: A rollable display apparatus includes a flexible display panel, a panel extension sheet connected to the flexible display panel, and a housing module. The flexible display panel is configured to be loaded into and unloaded from the housing module. The rollable display apparatus further includes a roller part in the housing module that has a double roller structure. The roller part is configured to individually wind and unwind each of the panel extension sheet and the flexible display panel.

Abstract: There is provided a TFT backplane having at least one TFT with oxide active layer and at least one TFT with poly-silicon active layer. In the embodiments of the present disclosure, at least one of the TFTs implementing the circuit of pixels in the active area is an oxide TFT (i.e., TFT with oxide semiconductor) while at least one of the TFTs implementing the driving circuit next to the active area is a LTPS TFT (i.e., TFT with poly-Si semiconductor).
