    摘要: Better performance can be provided for a display system that has semiconductor microelectronic components such as demultiplexors, gate line and data line drivers, and pixel switches formed on the display substrate, e.g., a glass substrate that constitutes part of an active matrix display panel. A threshold voltage of a constituent transistor of one of these microelectronic components, e.g., a pixel thin film transistor (TFT) that is part of a particular display element, may be measured using a replica component that emulates the behavior of the component.

    摘要: Methods and devices employing circuitry for reducing power usage of a touch-sensitive display are provided. In one example, a method includes receiving power for a display of an electronic device. The method also includes powering a touch subsystem and a display subsystem of the display. The method includes, in a standard display mode, storing a frame of data in pixels of the display subsystem during a first period of time. The method also includes, in a low power display mode, storing a frame of data in pixels of the display subsystem during a second period of time. The second period of time is not equal to the first period of time. The method includes detecting a touch of the display via the touch subsystem between each synchronization signal of a plurality of synchronization signals received by the display.

    摘要: Present techniques involve methods and systems of inversion patterns for pixels in a display. Inversion techniques involve driving image signals having a first polarity to data lines of a pixel matrix during a first time period and driving image signals having an opposite polarity to the data lines during a second time period. In some embodiments, the pixels may be configured to have electrodes having only two finger electrodes, thus widening the distance between electrodes and decreasing the susceptibility for crosstalk between pixels. In some embodiments, horizontal cross-talk of electromagnetic fields between pixels may be further reduced by configuring the data line driving scheme such that voltage polarity is flipped for the pixels along every two, three, or more data line columns. Furthermore, a Z inversion pattern may be employed to reduce the occurrence of undesirable display artifacts.
