  • Publication number: 20240243083
    Abstract: Provided are a driver IC and a display device. The driver IC includes at least one GOA pad area. Each of the at least one GOA pad area includes a plurality of first pads arranged in a plurality of rows and a plurality of columns. Each of the plurality of columns of the first pads is divided into at least two first pad groups arranged independently of each other. Each of the at least two of the first pad groups includes at least two of the first pads adjacent to each other, and the first pads in each of the first pad groups are electrically connected with each other. The driver IC further includes a plurality of leads electrically connected with the first pad groups, and each of the first pad groups is electrically connected with a different lead.
