  • Publication number: 20190187523
    Abstract: A display panel includes a first substrate, a second substrate, a display medium layer, pixel units, and a light-shielding conductive pattern layer. The first substrate has a first inner surface and a first outer surface, and the first outer surface serves as a display surface of the display panel. The second substrate is disposed opposite to the first substrate and has a second inner surface and a second outer surface. The display medium layer is disposed between the first inner surface and the second inner surface. The pixel units are disposed between the display medium layer and the first inner surface, and at least one of the pixel units includes an active element. The light-shielding conductive pattern layer is disposed between the display medium layer and the second inner surface, at least partially overlaps the active element in a vertical projection direction, and includes a first patterned light-shielding conductive layer and a first patterned low-reflection layer.

  • Publication number: 20170056282
    Abstract: A mouth-opening training device includes a water-filled bag having a zigzag edge or a sawtooth edge. By increasing or decreasing the amount of water located inside the water-filled bag to alter the total thickness of the water-filled bag, said device can accommodate different thickness of occlusion of teeth of a patient. Said device can make a further improvement on layers of flavor in occlusion of the teeth. Said device can further include a plurality of pivotable plate-shaped objects connected or coupled to the water-filled bag. The plate-shaped objects can provide different thickness combinations and further meet the user demands on thickness of occlusion of the teeth.

  • Publication number: 20100175229
    Abstract: An elastic clip that can be fabricated and assembled easily includes a first clipping blade, a second clipping blade, a pin and an elastic reed. The first clipping blade and second clipping blade face each other, and have respectively a pair of lugs in the middle corresponding to each other. Each lug has a transverse notch and a pin hole at a tail end of the notch to be wedged in transversely by the pin to couple the first and second clipping blades. The pin serves as a movement axis. The elastic reed is disposed between the first and second clipping blades by pushing from a rear side. The elastic reed has a first side blade and a second side blade retained by the first and second clipping blades, and a curved portion in the middle to press and surround the pin. Thus assembly can be done quickly and labor cost can be reduced. It provides significant improvements over the conventional elastic clip.

  • Publication number: 20020040800
    Abstract: A packaging structure of a chip is disclosed. The packaging structure has high heat conductivity and a preferred electric insulation and can protect the chip. The packaging structure includes a chip, a lead frame, a signal transmission device for being connected to the chip and lead frame, a protecting gel layer, a diamond-like carbon layer, and an electric insulating layer. By aforesaid structure, when the chip is working, the heat from the chip is dissipated through the diamond-like carbon layer under the hollowed portion so that a working temperature of the chip is retained in a normal temperature.
