摘要： Systems and methods for calibrating an electronic display to reduce or eliminate a mura artifact are provided. The mura artifact may be due to differential behavior of common voltage layers (VCOMs) in the electronic display. One method for reducing or eliminating the mura artifact may involve turning on an electronic display and programming pixels the electronic display to a uniform gray level. An initial luminance value may be determined and, after waiting a period of time, a subsequent luminance of the pixels may be measured. When a difference between the subsequent luminance and initial luminance is within a threshold, the mura artifact may be understood to have settled and the electronic display may be calibrated.

摘要： Design criteria of display screens is provided that can be used in combination with particular inversion schemes and scanning orders of the display screens to reduce or eliminate visual artifacts that can be caused by the effects of capacitive coupling of voltage changes in one part of the display into other parts of the display. Using particular combinations of inversion schemes and scanning orders, together with particular design criteria for the display screen, can allow one type of effect, e.g., an increase or decrease in a brightness of a display pixel, caused by one type of coupling effect, such as a coupling between data lines, can be offset by the effect caused by another type of coupling effect, such as a coupling between pixel electrodes.

摘要： With respect to liquid crystal display inversion schemes, a large change in voltage on a data line can affect the voltages on adjacent data lines due to capacitive coupling between data lines. The resulting change in voltage on these adjacent data lines can give rise to visual artifacts in the data lines' corresponding sub-pixels. Various embodiments of the present disclosure serve to prevent or reduce these visual artifacts by applying voltage to a data line more than once during the write sequence. Doing so can allow erroneous brightening or darkening caused by large voltage swings to be overwritten without causing additional large voltage swings on the data line.

摘要： Pre-charging display screen sub-pixels, such as aggressor sub-pixels, prior to the application of a target data voltage to the aggressor sub-pixels is provided. In some examples, a target voltage of a sub-pixel in a previous row in the scanning order of the display can be used to pre-charge sub-pixels. The row of sub-pixels to be pre-charged can be switched on during the updating of another row of sub-pixels. In this way, for example, target voltages applied to data lines while an update row is connected to the data lines, e.g., to update the update row, can be applied to the row to be pre-charged as well.

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.
摘要翻译：现有技术涉及显示器中像素的反演图案的方法和系统。反转技术涉及在第一时间段期间驱动具有第一极性的图像信号到像素矩阵的数据线，并且在第二时间段期间驱动与数据线具有相反极性的图像信号。在一些实施例中，像素可以被配置为具有仅具有两个指状电极的电极，从而加宽电极之间的距离并降低像素之间的串扰的敏感度。在一些实施例中，可以通过配置数据线驱动方案来进一步减少像素之间的电磁场的水平串扰，使得沿着每两个，三个或更多个数据线列的像素翻转电压极性。此外，可以采用Z反转图案来减少不期望的显示伪影的发生。
