Abstract: Provided are a double contact point switch and a magnetic connector having the same. The double contact point switch includes: a pin part; an additional terminal part; and an elastic part applying elastic force to the pin part, wherein the pin part includes a front contact point and a rear contact point, the pin part moves rearward when external force is applied to the front contact point of the pin part and again moves forward when the external force of the front contact point disappears, by the elastic part, and the rear contact point contacts the additional terminal part when the pin part moves rearward. As a result of this configuration, it is possible to confirm whether or not a contact of a magnetic connector was made without installing a separate signal terminal in the magnetic connector.

Abstract: Disclosed is a rollable display apparatus including: a flexible display panel that includes a pixel array; a roller part having a surface for winding the display panel; a first housing receiving the roller part and having a first opening through which a portion of the display panel passes; a rotational controller coupled between the roller part and the first housing, the rotational controller configured to: in a first state, enable the roller part to rotate in a first direction to unwind the display panel from the roller part but prevent rotation of the roller part in a second direction opposite the first direction, in a second state, enable the roller part to rotate in the second direction to wind the display panel onto the roller part, and switch from the first state to the second state responsive to receiving a triggering operation from a user.

Abstract: Provided is a charging system having a circuit for delaying power supply, and more particularly, a charging system having a circuit for delaying power supply installed on a side of a power supply apparatus, wherein the circuit for delaying power supply prevents a spark from being generated when an electronic device and the power supply apparatus are connected to each other. The circuit for delaying power supply blocks the power supply to the Vcc power terminal in the case in which the GND ground power terminal and the D signal terminal are not in an electrically shorted state and releases the blocking of the power supply to the Vcc power terminal because an operation of the transistor is changed and a charging state of the capacitor is changed in the case in which the GND ground power terminal and the D signal terminal become the electrically shorted state.

Abstract: The present invention relates to a method and apparatus for treating organic waste and producing solid fuel or compost from the treated organic waste.

Abstract: A backlight assembly having protrusions in a side surface between a side supporter and a cover shield is provided. The protrusions prevent the cover shield from being deformed by an external force and prevent disconnection of a wire between the side supporter and the cover shield. The backlight assembly includes a plurality of light sources; a side supporter having a plurality of U-shaped curved portions which align with and support the light sources; a PCB having a plurality of inverters mounted thereon; a plurality of wires which connect the inverter and an electrode of each light source; a cover shield with an edge for protecting end portions of the light sources and a second edge for protecting the PCB; and an extension formed on one surface of the side supporter opposite to the cover shield edge.
