Title:
DRIVING SUBSTRATE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/093270
Kind Code:
A1
Abstract:
A driving substrate (1) and a display device (100). The driving substrate (1) comprises a base substrate (10), a first metal layer (20) and a second metal layer (30) which are insulated, and an adapter layer (70); the first metal layer (20) and the second metal layer (30) respectively comprise a first wire (21) and a second wire (31); the first wire (21) and the second wire (31) are electrically connected by means of the adapter layer (70); part of the adapter layer (70) respectively extends into first through holes (51) and second through holes (52) to form first conductive holes (61) and second conductive holes (62); one first conductive hole (61) and one second conductive hole (62) form a group of conductive connection holes (60); the length of an intra-group current path of each group is smaller than the length of an inter-group path thereof; the length of the intra-group current path in any group is equal to the lengths of the intra-group current paths of other groups. The driving substrate (1) can reduce current density and reduce voltage drop.
