Title:
DRIVING BACKPLANE AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/115402
Kind Code:
A1
Abstract:
A driving backplane and a manufacturing method therefor, and a display device and a manufacturing method therefor. The manufacturing method for the driving backplane comprises: providing a base substrate (1), the base substrate (1) being provided with a first surface (101) and a second surface (102) which are arranged oppositely, and a side surface (103) being connected between the first surface (101) and the second surface (102); forming a flexible film layer (16) on the first surface (101), and patterning the flexible film layer (16) to form a first opening part (161), the first opening part (161) comprising a first part (1611), a second part (1612), and a third part (1613) which are connected in sequence; bending part of the flexible film layer (16) to the second surface (102), such that the first part (1611) is opposite to the first surface (101), the second part (1612) is opposite to the side surface (103), and the third part (1613) is opposite to the second surface (102); forming a conductive layer (17) on the side of the flexible film layer (16) away from the base substrate (1) by using the flexible film layer (16) as a mask, the conductive layer (17) being formed in at least part of the first opening part (161) to form a conductive strip (171); and removing at least the flexible film layer (16) and the conductive layer (17) around the conductive strip (171). The manufacturing method is simple in process, high in precision, and free of etching foreign matters.
