  • Patent number: 12154912
    Abstract: A display device according to one or more embodiments of the disclosure includes a pixel on a base layer; a gate driver configured to supply a gate control signal to the pixel through a gate line; pads including a first pad on the base layer and electrically connected to the pixel through a data line and a second pad on the base layer and electrically connected to the gate driver; and a protection circuit electrically connected to the pads. The protection circuit includes a first protection circuit electrically connected between the first pad and the pixel and a second protection circuit electrically connected between the second pad and the gate driver. The first protection circuit and the second protection circuit have different structures.

  • Patent number: 7746621
    Abstract: A bar type ionizer has a discharging electrode, a ground electrode, a high voltage unit, and a controller unit and uses the technique of eliminating static electricity by corona discharging. The ionizer also has a FND unit mounted on the bar which lets the user see the bar information including address of the bar, frequency, duty rate, alarm, run/stop state easily, plus buttons that let the user control the bar information easily, an air supply device installed around the needles in the air injecting socket which sends air, and a second air supply device installed around the needles having round sections and sending air to the end of the needles to eliminate the dust attached on the end of the needles. The ionizer has a streamlined section so that inside air flows smoothly. The second air supply device is elliptic with the minor axis smaller than the radius of the needle. The needle is positioned at the center of this elliptic groove and fixed by it.

  • Patent number: 7710707
    Abstract: A flexible ionizer uses soft X-ray and has a head unit generating soft X-ray whose wavelength is 1.2˜1.5 ?, a soft X-ray protect unit shielding the leak of the soft X-ray from the head unit, and a power control unit supplying a control signal and control voltage to the head unit. The head unit is positioned outside of the soft X-ray protect unit with the flexible ionizer further having a flexible tube protecting a high voltage cable that connects the head unit and power control unit from external impact or vibration and letting the user bend the head of the head unit at an arbitrary angle toward a charged body if necessary, a connecting device letting the ions generated at the window positioned inside of the body of the ionizer emit toward the charged body by connecting one end of the flexible tube and the head unit, and a connecting device connecting the other end of the flexible tube and the body of the ionizer.
