  • Patent number: 8283617
    Abstract: A display device is applied to a light sensing system. The display device includes a display module and a pattern layer. The pattern layer is made of optical material and formatted on the display module. The pattern layer includes patterned optical material and gaps without optical material. The pattern layer selectively reflects or absorbs invisible light with specific wavelength emitted from the display module, such that a light sensor cannot sense the invisible light reflected or absorbed by the optical material or just can sense a little invisible light through the optical material. However, the invisible light can be emitted out of the gaps without the optical material, such that the light sensor can selectively sense the invisible light. Based on the light sensing result, the light sensor can recognize the corresponding pattern.

  • Publication number: 20100265671
    Abstract: The package structure of the PCB comprises a substrate and a frame. The frame is located at the top of the substrate, and the substrate and the frame define a receiving space. The electronic components are mounted on the substrate and distributed in the receiving space. Because of the protection of the frame, the electronic components are effectively protected from the collision of installation in the process or use in the process. The substrate can be a flexible circuit board or a rigid-flex PCB and the electronic components are directly embedded in the substrate. Therefore the thickness of the package structure is reduced.
