2results about How to "Uniform line width" patented technology

A flexible circuit board includes a substrate, a plurality of circuit patterns disposed on the substrate, and a protective layer disposed on the circuit patterns, wherein each of the plurality of circuit patterns has a thickness greater than 8 µm and less than or equal to 25 µm, and wherein a thickness deviation between the plurality of circuit patterns is 0.5 µm to 3 µm. When the flexible circuit board is connected with a display panel, the display panel can have high performance and high current can flow through the display panel. The circuit pattern having the features according to the present invention is prevented from being damaged by high current.

This application relates to a method, apparatus, device, and medium for detecting lane line separation and merging points. The method includes: after acquiring a lane line image, performing skeletonization processing on the lane lines in the lane line image to obtain a lane line skeleton diagram; identifying all branch nodes on the lane line skeleton diagram, and determining pseudo branch nodes among all branch nodes; and eliminating pseudo branch lane lines corresponding to the pseudo branch nodes in the lane line skeleton diagram to obtain the real branch nodes in the lane line image, i.e., obtaining the lane line separation and merging points. The solution provided by this application can accurately detect lane line separation and merging points.
