  • Publication number: 20240090278
    Abstract: The disclosure relates to a display device including an oxide semiconductor pattern. The disclosure provides a driving thin film transistor and a switching thin film transistor using an oxide semiconductor pattern as an active layer. Each of the driving thin film transistor and the switching thin film transistor includes a light shielding pattern. The light shielding pattern includes a semiconductor material layer doped with P-type impurity ions. By virtue of the light shielding pattern including the semiconductor material layer, each of the driving thin film transistor and the switching thin film transistor exhibits an increase in threshold voltage and, as such, freedom of circuit design is secured.

  • Publication number: 20240072064
    Abstract: The disclosure provides an array substrate of a thin film transistor including an oxide semiconductor pattern, and a display device using the same. The thin film transistor array substrate includes a substrate including an active area and a non-active area disposed around the active area, and a first thin film transistor disposed on the substrate. The first thin film transistor includes a first oxide semiconductor pattern disposed on the substrate, a first gate electrode disposed under the first oxide semiconductor pattern while overlapping with the first oxide semiconductor pattern, a first source electrode and a first drain electrode disposed on the first oxide semiconductor pattern and connected to the first oxide semiconductor pattern, and a first light shielding pattern disposed over the first oxide semiconductor pattern and electrically connected to one of the first source electrode and the first drain electrode while overlapping with the first oxide semiconductor pattern.

  • Publication number: 20240074235
    Abstract: A display apparatus is provided. The display apparatus may include a light-emitting device and a pixel driving circuit electrically connected to the light-emitting device. The pixel driving circuit may supply a driving current corresponding to a data signal to the light-emitting device according to a gate signal. For example, the pixel driving circuit may include at least one thin film transistor. The thin film transistor may include an active pattern comprising an oxide semiconductor. A source region of the active pattern overlaps a source semiconductor pattern, and a drain region of the active pattern overlaps a drain semiconductor pattern. The source semiconductor pattern and the drain semiconductor pattern may include n-type impurities. A channel region of the active pattern may be outside the source semiconductor pattern and the drain semiconductor pattern. Thus, in the display apparatus, reliability of the pixel driving circuit may be improved.

  • Patent number: 6141998
    Abstract: A door lock device having an indoor and outdoor housing, each having inner tube-shaped supports, and further including indoor and outdoor handle connection members, each having at a first end handle connections with an indoor and an outdoor handle, respectively, and having at a second end opposite the first end driving cams formed with a cam curvature having step differences in an axial direction. Indoor and outdoor slide cylinders are provided having driven cams in contact with the driving cams and experiencing a rectilinear motion in the axial direction by means of the axial step difference. A first coupling spring is fixed to the indoor handle connection member and the indoor slide cylinder. A second coupling spring is fixed to the outdoor handle connection member and the outdoor slide cylinder. Indoor and outdoor end frames allow the indoor and outdoor slide cylinders to be guided rectilinearly in the axial direction by means of a rectilinear guide fitting.
