    摘要: A magnetic field control device is disclosed. A magnetic field control device includes: a housing having an accommodation space formed therein; a first magnet member which is positioned in the accommodation space, has a central shaft disposed parallel to a first axis, and generates a magnetic field; a second magnet member which is positioned at a side of the first magnet member in the direction of a second axis perpendicular to the first axis, has a central shaft disposed parallel to the first axis, and generates a magnetic field; a magnet drive part for rotating the first magnet member and the second magnet member around the central shafts thereof, respectively; and a control part for controlling the magnet drive part to adjust angles of the first magnet member and the second magnet member.

    摘要: A display device is provided including a display panel. A pixel of the display panel includes a light emitting element, first through sixth transistors, and a capacitor. The first transistor is connected between a power line and the light emitting element and operates depending on a potential of a first node. The second transistor is connected between a data line and a second node. The capacitor is connected between the first node and the second node. The third transistor is connected between the first transistor and the first node. The fourth transistor is connected between the first node and a reference voltage line. The fifth transistor is connected between the second node and the reference voltage line. The sixth transistor is connected between the power line and the second node.
