摘要： Common electrodes (Vcom) of integrated touch screens can be segmented into electrically isolated Vcom portions that can be operated as drive lines and/or sense lines of a touch sensing system. The touch screen can include high-resistivity connections between Vcom portions. The resistivity of the high-resistivity connections can be high enough so that touch sensing and image display can be performed by the touch screen, and the high-resistivity connections can provide an added functionality by allowing a charge build up on one of the Vcom portions to be spread to other Vcom portions and/or discharged from system by allowing charge to leak through the high-resistivity connections. In this way, for example, visual artifacts that result from charge build up on a Vcom portion can be reduced or eliminated.

摘要： An electronic device display may have an array of display pixels. Each pixel may receive display data on a data line and may have a thin-film transistor that is controlled by a gate line signal on a gate line. The transistors may be controlled to apply electric fields across liquid crystal material. A common electrode may be used to distribute common electrode signals to the display pixels. The display may have a segmented common electrode with isolated regions that serve as respective touch sensor electrodes. A display may include a display driver integrated circuit that is adjusted to produce clock signals (CLK) with desired rise and fall times (82, 84, 86). Gate driver circuitry such as thin-film transistor circuitry may include pass transistors controlled by latches. The pass transistors may be used in providing the clock signals (CLK) with the adjusted rise and fall times (82, 84, 86) to the gate lines to serve as gate line signals.
