  • Patent number: 11276674
    Abstract: A driving substrate includes a base substrate. The base substrate has a display region and a peripheral region, and the peripheral region includes a bonding region between the display region and a first side face of the base substrate. The driving substrate further includes a plurality of first pads spaced apart from each other, which are disposed in the bonding region of the base substrate. A first side face of each first pad is flush with the first side face of the base substrate. A thickness of the first pad is approximately in a range from 0.5 microns to 2 microns.
