Abstract: Disclosed are a display apparatus and a control method thereof, the display apparatus including: a display unit which includes a plurality of pixels with an organic light emitting diode (OLED); a power supply which supplies power to the display unit; an image processor which processes an image signal in accordance with the plurality of pixels; and a controller which divides the frame into a plurality of sub-frames, assigns bit weights to each of the divided sub-frames, and controls the power supply to supply a voltage which is adjusted by the assigned bit weights in accordance with the sub-frames to the display unit.

Abstract: A wireless power transmission apparatus and a wireless power transmission system are provided. The wireless power transmission apparatus includes a main body; and a support which is disposed on a side surface of the main body, wherein the main body includes a transmission resonator unit which generates a first magnetic field of a horizontal direction with respect a ground surface and a second magnetic field of a vertical direction with respect to the ground surface.

Abstract: An input device for a display screen is disclosed. The input device includes a plurality of conductive members which contact or approach the touch screen and provide various electrostatic capacitances. The conductive member includes a shock absorber at a contact end portion.

Abstract: A power supplying apparatus, a power supplying method, an organic light-emitting diode (OLED) display apparatus are provided. The OLED display apparatus includes: a plurality of components which are to perform an operation of the OLED display apparatus; a power supplying unit; a rectifier which rectifies an input voltage supplied from the power supplying unit; and a voltage level converter which converts a level of the input voltage rectified by the rectifier and supplies the input voltage having the converted level to the plurality of components.

Abstract: Disclosed are a display apparatus and a control method thereof, the display apparatus including: a display which displays an image; a touch panel which includes a plurality of pulse transmitting lines distributed with regard to a touch area of the touch panel, where voltage pulses are transmitted to the plurality of pulse transmitting lines, and a plurality of receiving lines distributed with regard to the touch area configured to detect a user's touch input on the touch area based on the voltage pulses transmitted to the pulse transmitting lines; and a controller configured to control a number of the voltage pulses to the plurality of pulse transmitting lines, where the number of the voltage pulses transmitted to the plurality of pulse transmitting lines corresponding to a touch expectation area of the touch area is greater than those voltage pulses transmitted to other areas of the touch area.
