Abstract: Disclosed is a display panel and a manufacturing method thereof. The display panel includes a plurality of ink layers applied in a cover window and a manufacturing method thereof.

Abstract: A display panel includes a cover window, an ink layer formed with a multi-layer structure on a rear surface of the cover window and directly adhered to a middle frame, and an adhesive layer disposed on the rear surface of the cover window and overlapping with the ink layer, and at least one layer of the multi-layer structure of the ink layer may include a conductive material. An electric charge generated by the cover window is distributed to the middle frame via the ink layer and discharged by the middle frame to prevent a shift phenomenon, a green phenomenon, or both in the display panel.

Abstract: A charging apparatus is disclosed that charges a smartphone in a high-speed charging mode or in a general charging mode in consideration of a voltage state of a vehicle battery, or does not charge the smartphone, such that the charging apparatus effectively copes with unexpected situations capable of occurring in the vehicle. Therefore, when a voltage of a battery embedded in the vehicle reaches a constant voltage, the charging apparatus charges the smartphone in a manner that the in-vehicle battery voltage is protected, and no problem occurs in the vehicle when the vehicle starts engine ignition in the future. As a result, the charging apparatus efficiently charges the battery of the smartphone by adjusting the current and the voltage according to a voltage drop situation during a high-speed charging mode or a general charging mode, thereby efficiently charging the smartphone battery without causing overload to the battery.
