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

Patent number: 7629633Abstract: A vertical thin film transistor (TFT) structure allows for a channel length to be scaled down, below that allowed by lateral TFT structures, to nanoscale (i.e., below 100 nm). However, while reducing the channel length, short-channel effects have been found in previous VTFT structures. Aspects of the new vertical TFT structure allow for the suppression of some of the short-channel effects. Advantageously, the capability of defining nanoscale channel length with short-channel effect suppression allows for p-channel vertical TFTs, where previously these were impractical. Furthermore, in aspects of the vertical TFT structure, the gate electrode is entirely vertical and by eliminating the horizontal overlap of the gate electrode over the drain electrode that present in earlier vertical TFT structures, parasitic gate-to-drain capacitance is eliminated.Type: GrantFiled: January 17, 2006Date of Patent: December 8, 2009Inventors: Isaac Wing Tak Chan, Arokia Nathan
