  • Patent number: 11063068
    Abstract: A display apparatus includes a substrate having a first substrate, a second substrate, and an inorganic insulating layer between the first substrate and the second substrate. A first buffer layer is on the substrate, wherein the first buffer layer includes n+1 layers, and ā€˜nā€™ is 0 or an even number. A first thin film transistor, a second thin film transistor, and a storage capacitor are each on the first buffer layer. The first thin film transistor includes a first active layer formed of a low temperature poly silicon material. The second thin film transistor includes a second active layer formed of an oxide semiconductor material. The storage capacitor includes a first capacitor electrode and a second capacitor electrode.
    Type: Grant

  • Patent number: 9954014
    Abstract: A thin film transistor substrate having two different types of thin film transistors on the same substrate, and a display using the same are discussed. The thin film transistor substrate can include a substrate, a first thin film transistor (TFT), a second TFT, a first storage capacitor electrode, an oxide layer, a nitride layer, a second storage capacitor electrode, a planar layer and a pixel electrode. The first TFT is disposed in a first area, the second TFT is disposed in a second area, and the first storage capacitor electrode is disposed in a third area on the substrate respectively. The oxide layer covers the first and second TFTs, and exposes the first storage capacitor electrode. The nitride layer is disposed on the oxide layer and covers the first storage capacitor electrode. The second storage capacitor electrode overlaps with the first storage capacitor electrode on the nitride layer. The planar layer covers the first and second TFTs, and the second storage capacitor electrode.
