Abstract: A tiling display device comprises a plurality of display devices, and a main circuit board driving the plurality of display devices. Each of the plurality of display devices includes a display panel that displays an image, a plurality of flexible films bonded to a rear surface of the display panel, and a printed circuit board electrically connected to the plurality of flexible films. A plurality of printed circuit boards of the plurality of display devices are cascaded to each other and the plurality of printed circuit boards have a same shape. Therefore, the efficiency of a manufacturing process of the plurality of printed circuit boards provided in a tiling display device can be improved.

Abstract: Disclosed are a power supply apparatus and a display apparatus including the same, which control a plurality of slave power supply apparatuses without any increase in number of terminals of a master power supply circuit. The power supply apparatus includes a master power supply circuit, a slave power supply circuit, and an enable signal line connected between the master power supply circuit and the slave power supply circuit. A voltage of the enable signal line is shifted based on an operation of the slave power supply circuit.
