  • Patent number: 12001245
    Abstract: An electronic product comprises: a sensing area that senses a touch, a non-sensing area adjacent to the sensing area and that does not sense a touch, a display panel that displays an image on a front surface, and a stack structure disposed on a rear surface of the display panel and that includes a plurality of conductive patterns that sense a touch. The plurality of conductive patterns includes first conductive patterns that extend across the sensing area and the non-sensing area. Each of the first conductive patterns has a first thickness in the sensing area and a second thickness in the non-sensing area that is less than the first thickness.
