Abstract: PURPOSE: A rectenna for a wireless power transmission is provided to receive power in all directions by non-directionally receiving power energy through a microwave by wireless. CONSTITUTION: A dielectric substrate(110) has a fixed dielectric constant. A ground plate(130) is formed on one side of the dielectric substrate. An antenna(120) transmits and receives a microwave in air. A rectification circuit electrically connects the antenna to the ground plate. The rectification circuit converts the microwave received from the antenna into DC power.

Abstract: PURPOSE: A wireless power receiving device is provided to improve conversion efficiency by receiving a radio frequency signal of a specific frequency band and changing the radio frequency signal into DC power. CONSTITUTION: A wireless reception unit(110) receives a radio frequency signal of a specific frequency band. The frequency of the radio frequency signal of the specific frequency band is 800MHz to 2.0GHz. An amplifier(120) amplifies the radio frequency signal of the specific frequency band. A rectification unit rectifies the radio frequency signal of k and changes it into DC power. A boosting circuit unit(150) amplifies each DC power. A combination unit combines the each power and outputs it.

Abstract: PURPOSE: An LED electronic display board and a driving chip embedded in the LED electronic display board reduce current consumption by including the driving chip controlling a unit module, where LEDs are connected in series, with one route. CONSTITUTION: A driving chip (20) controls the flash of an LED module (10). A power supply unit (30) supplies power to the LED module and the driving chip. The LED module is made up of multiple unit modules formed by connecting a predetermined number of LEDs in series. The driving chip includes multiple driving pins (21) connected to multiple nodes, respectively. The driving pin makes a current provided to the unit module from the power supply unit flow in a bypass route formed by the LED or a switch device.
