Abstract: A curved display module includes a curved display panel curved with a first curvature in a first direction. A plurality of flexible circuit films are connected to a side portion of the curved display panel. A plurality of driving chips are each mounted on the flexible circuit films. A printed circuit board is connected to the flexible circuit films and is curved with a second curvature in the first direction. Two sides parallel to each other of each of the flexible circuit films are in direct contact with the curved display panel at first and second contact points, respectively, and are in direct contact with the printed circuit board at third and fourth contact points, respectively. A distance between the first and third contact points is different from a distance between the second and fourth contact points.

Abstract: A display device includes a display panel, and a power management circuit including a switching regulator for supplying a power in a discontinuous conduction mode or in a continuous conduction mode, and a sensing circuit for sensing whether the switching regulator is operated in the discontinuous conduction mode, the switching regulator including a comparator for monitoring the supplied power, and an RS latch for receiving an output signal from the comparator, and the sensing circuit including a phase lock loop circuit for generating a first clock signal, a phase delay circuit for generating a second clock signal having a phase delayed from the first, and a determination circuit for outputting a first value when a pulse width of the output signal from the RS latch is small, and for outputting a second value when the pulse width of the output signal from the RS latch is not small.

Abstract: A display apparatus includes a housing having a pillar shape, a plurality of monitors, and a driving unit received in the housing and providing driving signals to the plurality of monitors. Each of the plurality of monitors displays an image through its front surface and back surface and includes side surfaces connecting the front surface and the back surface. One side surface of the side surfaces of each of the plurality of monitors is coupled to the housing. A thickness of each of the plurality of monitors decreases as a distance from the housing increases.
