    Abstract: A touch screen having layers. The touch screen can include a substrate upon which the layers of the touch screen are disposed, and a touch region including a touch pixel electrode, a first display sub-pixel and a second display sub-pixel. The touch screen can also include a sense connection coupled to touch sensing circuitry. An intermediate connection can be disposed between the touch pixel electrode and the sense connection, and can be coupled to the sense connection at the first display sub-pixel and the touch pixel electrode at the second display sub-pixel. In some examples, the sense connection can be disposed at least partially underneath a structure in the first display sub-pixel, such as a data line. In some examples, the intermediate connection can be comprised of a same material type as a structure in the first display sub-pixel, such as a gate line material.

    Abstract: A touch screen is disclosed that includes conductive elements in a display area and connecting traces for routing the conductive elements to other locations. The connecting traces can be routed underneath or over existing opaque structures in the display area, instead of in border areas adjacent to the display area, to minimize the effect of the connecting traces on the display aperture ratio. The lengths and/or widths of these connecting traces as well as the number of parallel connecting traces used to connect to a particular element can be selected to balance the load on the drive and/or sense circuitry and on display pixels caused by the connecting traces.

    Abstract: Improvement of visual uniformity of an integrated touch screen display is provided. A touch screen can include common electrodes separated by gaps in a Vcom layer. To improve visual non-uniformity in the display resulting from the gaps, a first set of semi-transparent dummy features (primary-dummy features) can be formed on a second layer at the locations of the gaps, and a second set of dummy features (supplementary-dummy features) can also be formed on the second layer or another layer to mitigate low spatial resolution of the primary-dummy features and/or non-uniform spacing of the primary-dummy features. In some examples, holes or slits can be formed in the Vcom layer at areas of the supplementary-dummy features to further improve visual uniformity.

    Abstract: Touch regions in a diamond configuration in a touch sensitive device are disclosed. Touch regions can include drive regions of display pixels to receive stimulation signals and sense regions of display pixels to send touch signals based on a touch or near touch. The drive regions and sense regions can be disposed diagonally adjacent to each other to form a diamond configuration. In an example diamond configuration, diagonal drive regions can be separate and unconnected from each other, while diagonal sense regions can be electrically connected to each other via their sense lines. The diagonal sense region connections can be in a forward diagonal direction, a backward diagonal direction, or a combination thereof. In an alternate example diamond configuration, diagonal drive regions can be electrically connected to each other via their drive lines, while diagonal sense regions can be electrically connected to each other via their sense lines. The diagonal drive and sense region connections can be in a forward diagonal direction, a backward diagonal direction, or combinations thereof. An exemplary touch sensitive device having a diamond configuration can be a touch screen.

    Abstract: The border routing of conductive traces in devices, such as displays, touch sensor panels, and touch screens, to improve border area space usage, thereby reducing device size, and to reduce trace resistance, thereby improving device operation, is disclosed. The conductive traces can form a staggered stair-step configuration in the device border area, in which the average widths of the traces can be different from each other and each trace can have segments with different widths. The conductive traces can be coupled to an active area of the device to transmit signals to and from the active area in accordance with a device operation. The varying widths can help improve the border area space usage, reduce trace resistance, and reduce the differences in resistance between traces.

    Abstract: A touch screen. In some examples, the touch screen can comprise a first element coupled to a first sense connection, and a second element coupled to a second sense connection. In some examples, the first and second sense connections can be configured such that a load presented by the first sense connection and the first element is substantially equal to a load presented by the second sense connection and the second element. In some examples, the first and second sense connections can comprise detour routing configured such that a resistance of the first sense connection is substantially equal to a resistance of the second sense connection. In some examples, the first and second sense connections can be coupled to dummy routing configured such that a first capacitance presented by the first sense connection is substantially equal to a second capacitance presented by the second sense connection.

    Abstract: Reduction of the effects of differences in parasitic capacitances in touch screens is provided. A touch screen can include multiple display pixels with stackups that each include a first element and a second element. For example, the first element can be a common electrode, and the second element can be a data line. The display pixels can include a first display pixel including a third element connected to the first element, and the third element can contribute to a first parasitic capacitance between the first and second elements of the first display pixel, for example, by overlapping with the second element. The touch screen can also include a second display pixel lacking the third element. The second display pixel can include a second parasitic capacitance between the first and second elements of the second display pixel. The first and second parasitic capacitances can be substantially equal, for example.
