  • Patent number: 11216039
    Abstract: A flexible display includes a bottom plate, a support plate, two hinge modules, a frame body, a bending module and a flexible panel. The support plate is provided with a first end and a second end. The first end is rotatably connected to the bottom plate. The hinge modules are disposed at the second end of the support plate. The frame body is provided with a fixed frame and a plurality of turning frames. The fixed frame is connected to the hinge modules. The plurality of turning frames are pivoted to two opposite sides of the fixed frame respectively. The bending module is connected with the fixed frame and the plurality of turning frames. The flexible panel is disposed on the frame body and covers the bending module. When the flexible display is switched to a touch mode, the bending module drives the plurality of turning frames to be flush with the fixed frame so that the flexible panel is in a flat plate shape.

  • Publication number: 20210050478
    Abstract: The light-emitting diode package includes a plurality of bumps being a couple corresponding to each other. Each of the bumps has a first part and a second part placed under the first part, and a gap is formed between the bumps in a period-repeating wriggle shape or an irregular wriggle shape. Accordingly, the distance between the bumps of the light-emitting diode package is small, which results in a less stress being concentrated at the space between the bumps, as a result, a crack is difficultly caused by the stress to the light-emitting diode package. In other words, the structural strength between the bumps and the covering part is enhanced. Still, while being manufactured, the yield rate of the light-emitting diode package is also improved since there is almost no crack to reduce the yield rate.
