摘要： 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.

摘要： A chip bonding method and a bonding device. The chip bonding method is used for bonding a chip to a display module, the display module includes a substrate and a functional layer on the substrate, the substrate includes a first substrate portion and a second substrate portion, the functional layer is on the first substrate portion, and an electrode is on an upper side of the second substrate portion. The chip bonding method includes: forming a light absorbing film layer on a side of the second substrate portion facing away from the electrode; coating a conductive adhesive film on the electrode, and placing the chip on the conductive adhesive film; and irradiating, by using a laser beam, a side of the second substrate portion facing away from the electrode.
