  • Publication number: 20240162114
    Abstract: A power module including at least one power device, an insulation thermally conductive layer, and a heat dissipation device is provided. The insulation thermally conductive layer has a patterned circuit layer. The power device is disposed on the patterned circuit layer and is electrically connected to the patterned circuit layer. The heat dissipation device includes a heat dissipation plate and a heat dissipation base. The heat dissipation plate has a first surface and a second surface opposite to each other, and the insulation thermally conductive layer is disposed on the first surface. The heat dissipation base is partially bonded to the heat dissipation plate, and a chamber is formed between the heat dissipation plate and the heat dissipation bases. The heat dissipation base has a plurality of first heat dissipation bumps located in the chamber.

  • Patent number: 8289485
    Abstract: A liquid crystal display panel including several first electrode portions, several second electrode portions, and a smectic liquid crystal layer is provided. The first electrode portions and the second electrode portions are disposed on a first substrate. When an AC voltage is applied on the first electrode portions and the second electrode portions, the direction of a horizontal electrical field formed between each first electrode portion and the adjacent second electrode portion is parallel to the surface of the first substrate. The smectic liquid crystal layer is interposed between the first substrate and a second substrate. During the phase change of a liquid crystal molecule of the smectic liquid crystal layer, the horizontal electrical field generated by applying the AC voltage on the first electrode portions and the second electrode portions facilitates the alignment of the liquid crystal molecule of the smectic liquid crystal layer.
