Title:
LASER SPLICING METHOD, CONDUCTIVE FILM, TOUCH MODULE, CAPACITIVE TOUCH SCREEN AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/166650
Kind Code:
A1
Abstract:
A laser splicing method, applied to a conductive film, comprising: dividing the conductive film into a plurality of step-by-step etching regions spliced together; and sequentially performing etching in each of the step-by-step etching regions by means of a laser, so as to form a spliced non-conductive pattern, the non-conductive pattern comprising several polygonal unit patterns (1); each step-by-step etching region is formed by surrounding of first splicing lines (2) each provided at an intersection of two adjacent unit patterns in a first direction and second splicing lines (3) provided in a second direction, contour lines of two adjacent unit patterns intersect and form acute angles with the first splicing line, and the first direction and the second direction form a certain angle with each other. By means of said method, the problem of short circuit of a conductive film caused by splicing misalignment can be avoided. Further involved are a conductive film, a touch module, a capacitive touch screen and an electronic device.
