The calibration system may include calibration computing equipment and a test chamber having a light sensor. The calibration computing equipment may be configured to operate the light sensor and the display to gather display intensity performance data for obtaining a display gamma model. The display intensity performance data may be gathered using a range of display control settings that will be used in performing color calibration operations for the display. The calibration computing equipment may be configured to operate the light sensor and the display to gather display color performance data for determining a display white point calibration.

    摘要: Methods and devices employing circuitry for quickly discharging pixels of a display before the display is turned off are provided. In one example, a method may include receiving at the electronic display a signal indicating the electronic display will be powered off within a period of time. The method may also include, in response to the signal, causing a frame of pixel data originating from the electronic display to be stored in pixels of the electronic display before the electronic display is powered off. Storing the frame of pixel data in the pixels may inhibit image artifacts from occurring on the electronic display when the electronic display is powered back on in the future.

    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 floating data lines due to capacitive coupling between data lines. The change in voltage on these floating data lines can be increased when the application of voltage to the data line occurs after a toggling operation of the Vcom, i.e., when a voltage applied to the Vcom changes the voltage on the Vcom from one polarity to an opposite polarity. Various embodiments of the present disclosure serve to eliminate or reduce the effects of Vcom voltage toggling on data line voltages by applying a voltage (e.g., a fixed voltage) to the data lines while the voltage on Vcom toggles.

    摘要: Systems, methods, and devices are provided to calibrate an electronic display to reduce or eliminate mura artifacts. Such mura artifacts may be due to differential behavior of multiple common voltage layers (VCOMs) of the display. One method for reducing or eliminating such muras may involve setting pixels of an electronic display to a gray level and setting an operating parameter of the liquid crystal display to a starting value. An image of the pixels may be captured. Using the image, an average luminance of the pixels may be determined and the image may be amplified around the average luminance to enhance contrast of the image. When the amplified image substantially does not indicates the presence of a mura, the value of the operating parameter may be stored in the electronic 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.
