  • Publication number: 20240387787
    Abstract: A display apparatus includes a light-transmitting substrate, a pad group, a mini-IC, a first wire, and a first light-emitting element. The pad group includes a first pad, a second pad, and a third pad. The mini-IC is bonded to the pad group. The first wire is electrically connected to the first pad. The first pad and the second pad have first sides and second sides opposite to each other. The third pad is located on the first sides of the first pad and the second pad. The first wire is structurally separated from the second pad and the third pad. A winding segment of the first wire is disposed between the second pad and the third pad and bypasses the second pad from the first sides of the first pad and the second pad so as to extend toward the second sides of the first pad and the second pad.

  • Patent number: 10879218
    Abstract: A method of manufacturing a display device includes the following steps. A bonding pad is formed on a dielectric layer. A light-shielding material is formed on the dielectric layer. A temperature of the light-shielding material is increased such that the light-shielding material is cured into a light-shielding layer. During curing the light-shielding material into the light-shielding layer, the light-shielding material flows to and contacts a portion of a surface of the bonding pad. A light-emitting element is electrically connected to the bonding pad.
