  • Patent number: 12243491
    Abstract: A display panel includes a scan driving circuit. The scan driving circuit includes a first transistor that outputs a high-voltage of a scan signal during a turn-on period. The first transistor includes a first semiconductor pattern layer including a first input region, a first output region, and a first channel region, a first gate electrode overlapping the first channel region, a second semiconductor pattern layer including a second input region electrically connected to the first input region, a second output region electrically connected to the first output region, and a second channel region overlapping the first channel region, and a second gate electrode overlapping the second channel region, and electrically connected to the first gate electrode.

  • Publication number: 20250053255
    Abstract: A display device includes a display panel and an input sensor. The input sensor may include a first sensing electrode, a signal line electrically connected to a first terminal of the first sensing electrode, a first line at least partially overlapping the first sensing electrode and extending in the same direction as the first sensing electrode in the active area, and a first switching element defining a first current path in the first sensing electrode and the first line or blocking the first current path.

  • Patent number: 12223883
    Abstract: A display device includes: a pixel including a light emitting element, a first capacitor connected between a first node and a second node, and a second capacitor connected between the second node and a third node. The pixel further includes: a first transistor connected between the second node and the light emitting element to operate depending on potential of the first node; a second transistor connected between the third node and a data line to operate depending on a first scan signal; a third transistor connected between the third node and the second transistor to operate depending on a light emitting control signal; a fourth transistor connected between a reference voltage line and a first node to operate depending on the second scan signal; and a fifth transistor connected between the reference voltage line and the third node to operate depending on a third scan signal.

  • Patent number: 11863627
    Abstract: A smart home device including an input interface; a communication interface configured to communicate with a server and at least a first target device; and a processor configured to control the communication interface to communicate with the server using a first communication protocol to receive first target device format information describing a first communication control device format for communicating and controlling the first target device to perform a first operation, receive a first control command for communicating with and controlling the first target device input from the input interface, control the communication interface to communicate with the first target device using a second communication protocol different than the first communication protocol, wherein the first target device does not communicate with the server using the second communication protocol, convert the first control command into a format described by the first target device format information, and transmit the converted first con
