The invention discloses a display panel and a display device, the display panel further comprises a substrate, a driving circuit layer, a display film layer, a packaging film layer, a packaging barrier dam, a flat layer and a touch wiring layer, and the driving circuit layer is arranged on the substrate; the flat layer is arranged on the packaging film layer, and the touch control wiring layer is arranged on the flat layer; wherein the flat layer is provided with a via hole in the area where the packaging blocking dam is located, and the touch control wiring layer extends towards the edge of the display panel along the via hole. The via holes are formed in the flat layer, and the touch routing layer on the flat layer extends downwards from the position of the packaging barrier layer, so that the problems of breakage and short circuit of the touch routing caused by a process reason when the touch routing is formed on the section of the flat layer are solved, the touch routing has good performance, and the touch routing quality is improved. Therefore, the display and touch effects of the display panel are better.

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.

The present invention relates to the technical field of electromagnetic shielding materials, and specifically discloses a curved metal mesh electromagnetic shielding optical window and a preparation method and application thereof. The present invention adopts a variable speed laser direct writing method for scanning exposure, thereby improving the line width uniformity of different glue thickness areas; at the same time, metal aluminum is used as the metal shielding material, and an alkaline solution is used to develop and etch it, thereby successfully preparing a curved metal mesh electromagnetic shielding optical window with high line width uniformity. The present invention effectively solves the problems of uneven photoresist coating in the preparation process of the curved metal mesh in the prior art, such as poor line width uniformity and transmittance, difficulty in stripping the metal film, and corrosion of the metal optical window by the metal etching solution. The prepared metal mesh window takes into account both high transmittance and superior electromagnetic shielding performance.

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.
