Abstract: A measuring system comprises a pulse generator, an under test device, a variable resistor and a detecting control system. The pulse generator provides pulse signals with different voltage peaks to the under test device and the variable resistor. The variable resistor adjusts its resistance value according to a control signal. The detecting control system detects the voltage ringing ranges of the first terminal of the under test device at different resistance values. The detecting control system generates the control signal to adjust the resistance value of the variable resistor according to the voltage ringing ranges.

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.

Abstract: 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.

Abstract: The antenna on hand held devices, such as the iPhone or iPad, can be subject to interference from other circuitry on the device. Such interference may come from high frequency switching of nearby display circuitry, such as de-multiplexors or other circuits. To address this issue, the switching rates may be slowed in certain circuits by adding resistance and/or capacitance, thus raising the RC time constant and slowing the switching times to reduce the high frequency components. Alternatively or in addition to, an EMI shield can be placed over some or all of the display driving circuitry to shield the antenna from high frequency interference.

Abstract: A display may have a thin-film-transistor layer with a substrate layer. A layer of dielectric may be formed on the substrate layer and may have an upper surface and a lower surface. The thin-film-transistor layer may include an array of display pixels. Data lines and gate lines may provide signals to the display pixels. Gate driver circuitry in an inactive peripheral portion of the display may include a gate driver circuit for each gate line.

Abstract: Display ground plane structures may contain slits. Image pixel electrodes in the display may be arranged in rows and columns. Image pixels in the display may be controlled using gate lines that are associated with the rows and data lines that are associated with the columns. An electric field may be produced by each image pixel electrode that extends through a liquid crystal layer to an associated portion of the ground plane. The slits in the ground plane may have a slit width. Data lines may be located sufficiently below the ground plane and sufficiently out of alignment with the slits to minimize crosstalk from parasitic electric fields. A three-column inversion scheme may be used when driving data line signals into the display, so that pairs of pixels that straddle the slits are each driven with a common polarity. Gate line scanning patterns may be used that enhance display uniformity.

Abstract: A gate signal adjustment circuit for a display is disclosed. The gate signal adjustment circuit can adjust a transition time of a gate signal used to drive data displaying. The adjustment can be to either speed up or slow down the transition time according to the requirements of the display. In an example, the gate signal adjustment circuit can include multiple transistors, where a first set of the transistors outputs the gate signal and a second set of the transistors outputs an adjustment to the gate signal. The second set of transistors can be the same or different sizes depending on the desirable number of adjustment options. The circuit can also include a control line coupled to the second set of transistors to control the adjustment output. Gate signal adjustment can reduce crosstalk in the display.
