A curved display apparatus and a multi display system having the same are provided. The curved display apparatus includes a display panel, and a fixation member which fixes the display panel so that the display panel is curved with multiple curvatures.

Curved display apparatus and multi display apparatus having the same

A method of supplying a power to elements in a power supply apparatus including a primary side and a second side. Particularly, a method of supplying a driving power to an element at the primary side of the power supply apparatus from a primary coil of a transformer. A power factor improvement section improves a power factor of a received alternating current (AC) power. A transformer then receives the AC power having the improved power factor from a primary coil and generates an induced power at a secondary coil. The transformer then provides the AC power to drive a predetermined element located at the primary side of the power supply apparatus from the primary coil.

Power supply apparatus and method

A method of forming a dielectric layer in a capacitor adapted for use in a semiconductor device is disclosed. The method includes forming a first ZrOlayer, forming an interfacial layer using a plasma treatment on the first ZrOlayer, and forming a second ZrOlayer on the interfacial layer.
