Patent number: 11842005Abstract: In some examples, a touch screen includes resistors between the touch electrodes and routing traces. In some examples, the resistors can include a transparent conductive material included in the touch electrodes of the touch screen. The resistors can be located in a border region of the touch screen that can surround an active area of the touch screen that can include the touch electrodes and display pixels of the touch screen, for example. In some examples, the resistors included in the touch screen can have different resistances from each other and the same outer dimensions as one another. The resistors can reduce the variation in resistance from channel to channel in the touch screen, which can improve touch screen performance, for example.Type: GrantFiled: February 13, 2023Date of Patent: December 12, 2023Assignee: Apple Inc.Inventors: Zhou Lu, Isaac Wing-Tak Chan, Justin Zachary Wu, Rangarajan Krishnan, Qingbo Guo, Chao Zhang
