  • Publication number: 20240128324
    Abstract: A field effect transistor includes a substrate having a transistor forming region thereon; an insulating layer on the substrate; a first graphene layer on the insulating layer within the transistor forming region; an etch stop layer on the first graphene layer within the transistor forming region; a first inter-layer dielectric layer on the etch stop layer; a gate trench recessed into the first inter-layer dielectric layer and the etch stop layer within the transistor forming region; a second graphene layer on interior surface of the gate trench; a gate dielectric layer on the second graphene layer and on the first inter-layer dielectric layer; and a gate electrode on the gate dielectric layer within the gate trench.

  • Patent number: 11956994
    Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.

  • Patent number: 11740711
    Abstract: A mouse includes a main housing, a key structure, and a pressing force adjusting component. The key structure has a connecting end, a free end, and an elastic section. The connecting end is connected to the main housing, and the elastic section is located between the connecting end and the free end. The pressing force adjusting component is movably disposed on the main housing and has a limiting portion, and the limiting portion limits elastic deformation of the elastic section. A location of the pressing force adjusting component on the main housing is adapted to be changed to change a location of the limiting portion at the elastic section.
