  • Publication number: 20240395865
    Abstract: A thin film transistor includes a semiconductor layer, a gate insulating layer, a gate, a source and a drain. The semiconductor layer has a first heavily doped region, a second heavily doped region, a third heavily doped region, an intrinsic region and a lightly doped region. The gate shields the intrinsic region and a first portion of the first heavily doped region. A second portion of the first heavily doped region is located outside an area of the gate. The source and the drain are electrically connected to the second heavily doped region and the third heavily doped region respectively. The source and the drain are arranged in a first direction. The first portion of the first heavily doped region and the gate have an overlapping region. A length of the overlapping region in the first direction is greater than a length of the intrinsic region in the first direction.

  • Patent number: 12125870
    Abstract: A stretchable display panel includes a first stretchable film, a first transparent optical clear adhesive, a patterned organic layer, multiple light-emitting elements, and multiple wires. The first transparent optical clear adhesive is located on the first stretchable film. The patterned organic layer includes multiple first island portions and multiple first bridge portions. Any adjacent two of the first island portions are connected via a corresponding one of the first bridge portions. The light-emitting elements are located above the first island portions. The first transparent optical clear adhesive is located between the light-emitting elements and the first stretchable film. A first surface of the patterned organic layer faces away from the light-emitting elements. An included angle between the first surface and a first side surface of the first island portions is greater than 90 degrees. The wires are located above the first bridge portions.
