    • Disclosed herein is a stereoscopic image display apparatus capable of wirelessly transmitting and receiving power. The stereoscopic image display apparatus includes a stereoscopic image display unit and shutter glasses. The stereoscopic image display unit divides stereoscopic images into images for the left eye and images for the right eye and displays the resulting stereoscopic images, generates a signal of opening/closing a right eye shutter and a left eye shutter, and generates a power signal and then wirelessly transmits power in a magnetic resonance coupling manner. The shutter glasses wirelessly receives the power signal from the stereoscopic image display unit in the magnetic resonance coupling manner, and provides the images for the left eye and the images for the right eye by alternatively opening and closing the left eye shutter and the right eye shutter in response to the signal of opening/closing the right eye shutter and the left eye shutter.

    • Disclosed herein is a wireless charging system that includes a transmission device including a primary coil and a reception device including a secondary coil, wherein the transmission device detects an input signal provided from the primary coil to generate an output signal in the form of a pulse, and compares the level of the generated output signal with a reference voltage to generate a detection signal for determining the presence or absence of the reception device. The wireless charging system does not require an analog-to-digital converter (ADC), eliminating the necessity of using an ADC chip or a high-priced control circuit including an ADC block, thus reducing a material cost of the system. In addition, since the wireless charging system does not require a software algorithm for processing an ADC signal, the performance can be improved.
