Patent number: 11494016Abstract: A touch integrated display device includes a substrate, at one metal layer, a touch sensor and trace layer, and a shielding layer. The substrate includes an active area and a fan out area neighbouring to the active area. The metal layer is disposed over the substrate in the active area, extended to the fan out area and includes a plurality of source lines and a plurality of gate lines. The touch sensor and trace layer is disposed over the metal layer in the active area and extended to the fan out area. The shielding layer is at least disposed at an overlap region of the fan out area where the metal layer and the touch sensor and trace layer are overlapped from a top view to shield electromagnetic interference between the metal layer and the touch sensor and trace layer.Type: GrantFiled: January 11, 2021Date of Patent: November 8, 2022Assignee: Novatek Microelectronics Corp.Inventors: Yu-Ying Tang, Ching-Yang Pai, Chih-Chang Lai
