Abstract:
The present disclosure provides a display system including: a display apparatus; a wireless power reception apparatus configured to supply power to the display apparatus; and a wireless power transmission apparatus configured to emit a laser beam toward the wireless power reception module, wherein the wireless power reception module is formed as a bar type; and the wireless power transmission module comprises a light source configured to emit light of a specific wavelength as a laser beam, and a light shaping unit configured to shape the light of the light source and to convert the shaped light into a laser beam having a different cross-section and output the laser beam. Accordingly, by performing wireless power transmission using laser light, which satisfies the electromagnetic interference (EMI) requirements, wireless power may be transmitted to high-quality wall-mounted TVs and AV devices.
