    摘要: A display having data lines that can be configured between a display mode and a touch mode is disclosed. The display can have sense regions for sensing a touch or near touch on the display during the touch mode. These same regions can display graphics or data on the display during the display mode. During display mode, the data lines in the sense regions can be configured to couple to display circuitry in order to receive data signals from the circuitry for displaying. During touch mode, the data lines in the sense regions can be configured to couple to corresponding sense lines in the regions, which in turn can couple to touch circuitry, in order to transmit touch signals to the circuitry for sensing a touch or near touch. Alternatively, during touch mode, the data lines in the sense regions can be configured to couple to ground in order to transmit residual data signals to ground for discarding.

    摘要: A gate driver circuit for switching gate line voltage supplies between display and touch modes is disclosed. The circuit can include one or more switches configured to switch one or more gate lines of an integrated touch sensitive display between a display mode and a touch mode. During touch mode, the circuit can be configured to switch the gate lines to connect to a more stable voltage supply. The circuit can also be configured to reduce or eliminate interference from the display circuitry to the touch circuitry that could affect touch sensing. During display mode, the circuit can be configured to switch the gate lines to connect to a fluctuating voltage supply.

    摘要: Displays with touch sensing circuitry integrated into the display pixel stackup are provided. Circuit elements, such as touch signal lines, such as drive lines and sense lines, grounding regions, in the display pixel stackups can be grouped together to form touch sensing circuitry that senses a touch on or near the display. An integrated touch screen can include multi-function circuit elements that can operate as circuitry of the display system to generate an image on the display, and can also form part of a touch sensing system that senses one or more touches on or near the display. The multi-function circuit elements can be, for example, capacitors in display pixels that can be configured to operate as storage capacitors/electrodes, common electrodes, conductive wires/pathways, etc., of the display circuitry in the display system, and that may also be configured to operate as circuit elements of the touch sensing circuitry.

    摘要: 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.

    摘要: Touch screens with more compact border regions can include an active area that includes touch sensing circuitry including drive lines, and a border region around the active area. The border region can include an area of sealant deposited on conductive lines, and transistor circuitry, such as gate drivers, between the active area and the sealant. The conductive lines can extend from the sealant to the active area without electrically connecting to the transistor circuitry. The conductive lines can have equal impedances and can connect the drive lines to a touch controller off of the touch screen. A set of drive signal characteristics for the drive lines can be obtained by determining a transfer function associated with each drive line, obtaining an inverse of each transfer function, and applying a set of individual sense signal characteristics to the inverse transfer functions to obtain the corresponding set of drive signal characteristics.
