  • Publication number: 20240371741
    Abstract: A layout structure of a flexible circuit board includes a flexible substrate, a circuit layer and a dummy circuit layer which are arranged on the flexible substrate. The circuit layer includes first inner leads, second inner leads, an inverted U-shape connection line and a horizontal inner lead. A first distance between the first inner leads is less than a second distance between the second inner leads. One of dummy leads of the dummy circuit layer is located between the first and second inner leads, another dummy lead is located between the second inner leads. The dummy leads are provided to allow lead spaces on both sides of the inverted U-shape connection line is the same. Thus, etching solution will not flow laterally in an etching space between the inverted U-shape connection line and the horizontal inner lead.

  • Patent number: 8897548
    Abstract: A low-complexity method of converting 2D images/videos into 3D ones includes the steps of identifying whether each pixel in one of the frames is an edge feature point; locating at least two vanishing lines in the frame according to the edge feature point; categorizing the frame into the one of close-up photographic feature, of landscape feature, and of vanishing-area feature; if the frame is identified to have the vanishing-area feature or the landscape feature to generate a GDM; and apply a modificatory procedure to the GDM to generate a final depth information map; if the frame is identified to have the close-up photographic feature, distinguish between a foreground object and a background information in the frame and define the depth of field to generate the final depth information map.
