A skin care device according to an embodiment of the present disclosure includes an outer case having a first opening, an inner case configured to be fastened to the outer case and having a second opening corresponding to the first opening, and a light output module configured to be accommodated between the outer case and the inner case, in which the light output module includes a module body configured to form a predetermined area based on a shape of the outer case or the inner case, a module cover formed along a part of an outer part of the module body, and, between the module body and the module cover, a plurality of light sources disposed in an array form along the outer part of the module body, and in which each of the plurality of light sources is disposed to face the module body.

Skin care device

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.

Tiling display device

A power supply and a display device using the same are provided. The power supply includes a logic voltage generator and a power voltage generator. The logic voltage generator generates an internal logic voltage based on an externally input voltage. The power voltage generator generates a plurality of power voltages based on the external input voltage. When the external input voltage is cut off, the power voltage generator stops outputting a drain voltage, and then stops outputting a half drain voltage.

Power supply and display device using the same
