Abstract: A display driving device includes a power circuit, a gate driver, a data driver, and a controller. The power circuit generates gate supply voltages. The gate driver applies a gate driving signal to gate lines. The data driver applies data signals to data lines intersecting the gate lines. The controller controls the power circuit, the gate driver, and the data driver to set the gate driving signal to be at least one of the gate supply voltages when abnormal power off occurs. The controller also controls the power circuit to allow the gate supply voltages to be discharged naturally.

Abstract: A display driver integrated circuit (IC) and a display system including the same are provided. The display driver IC includes: a charge pump including a first node and a second node; a flying capacitor connected between the first node and the second node; a voltage regulator; a first switch connected between an output terminal of the voltage regulator and one of the first node and the second node; and a second switch connected between a ground and the other of the first node and the second node.

Abstract: A hair extension includes a hair weft. The hair weft is made of individual strands of human or synthetic hair. Far infrared powder is deposited onto Polyurethane (PU) and/or Keratin adhesive glue and webbing of silk or synthetic lace is incorporated with hair weft to create the human or synthetic hair PU and/or Keratin skin as connection strip(s). A connection strip receives connected ends of the individual strands of human or synthetic hair. A top adhesive strip is disposed on a top side of the connection strip and a bottom adhesive strip is disposed on a bottom side of the connection strip. The top and bottom adhesive strips both have a left side and a right side. The left side of the top adhesive strip and right side of the top adhesive strip are divided by an adhesive parting line.

Abstract: An electronic device includes a circuit protection unit providing over-current protection to a main circuit and including a series connection of first and second current limiting circuits, and a normally-open branch circuit coupled in parallel to the first current limiting circuit and operable to conduct when a voltage across the first current limiting circuit reaches a first predetermined threshold voltage not greater than an endure voltage of the first current limiting circuit. Prior to conduction of the branch circuit, the first current limiting circuit maintains a current flowing therethrough at a first limit value when a current flowing through the main circuit reaches the first limit value. Upon conduction of the branch circuit, the second current limiting circuit maintains a current flowing therethrough at a second limit value greater than the first limit value when the current flowing through the main circuit reaches the second limit value.
