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.

Methods and devices for improving image quality in a display having multiple common voltage layers (VCOMs) are provided. In one example, a method may include maintaining a deactivation signal on pixels of the display after programming a frame of data onto the pixels of the display, but before a touch sequence. The method may also include supplying a first data signal to each pixel of a first set of pixels coupled to a first VCOM while maintaining the deactivation signal. The method may include supplying a second data signal to each pixel of a second set of pixels coupled to a second VCOM while supplying the first data signal. The first data signal is supplied to each pixel of the first set of pixels and the second data signal is supplied to each pixel of the second set of pixels to inhibit image distortion during the touch sequence.

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:
Systems and methods for calibrating an electronic display to reduce or eliminate artifacts are provided. One method for reducing or eliminating artifacts may involve baking the operational—but not yet fully calibrated—electronic display to reduce stray charge on the electronic display. After baking the display, the electronic display may be calibrated to reduce or eliminate flicker and/or mura artifacts
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:
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.
