摘要： Methods and devices employing zero-bias display turn-off circuitry, including turn-off logic and switching devices, are provided. In one example, a method may include supplying a common voltage output of ground to a common electrode of a pixel of an electronic display, supplying an activation signal to the pixel to activate the pixel, supplying a data signal of ground to a pixel electrode of the pixel, and removing the activation signal from the pixel while the data signal is being supplied to the pixel to store the data signal in the pixel. When the activation signal is removed, the method may include causing the common voltage output being supplied to the common electrode of the pixel to change to a floating value to prevent a kickback voltage from affecting the data signal stored in the pixel.

摘要： A system and device for reducing ground bounce in circuitry. Utilization of a common ground supplied to multiple integrated circuits reduces the complexity and costs of producing circuitry but tends to interfere with signal quality within the circuitry by subjecting each integrated circuit to the ground bounce of every other integrated circuit. By introducing a source follower to selectively decouple and/or couple slave circuits within the circuitry, the ground bounce for the overall system can be reduced, thereby increasing the efficiency of interpreting signals within the circuitry.

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： A method and system is disclosed for powering device sub-circuitry of an electronic device. The sub-circuitry may be used to provide control signals to a direct current switcher on a main system board, thus eliminating passive circuitry typically associated with the sub-circuitry. Furthermore, by actively generating the control signals for the direct current switcher, explicit timing control circuitry is not required to synchronize the transmitted power to the sub-circuitry.

摘要： Methods and devices employing circuitry for display turn-off that offsets the effect of kickback voltage are provided. In one example, a method may include determining an amount of kickback voltage that is expected to occur in pixels of the electronic display during shutdown of the display, supplying a common voltage output to a common electrode of a pixel of the electronic display, and supplying an activation signal to the pixel to activate the pixel. The method may also include supplying a data signal to a pixel electrode of the pixel. The data signal may be substantially equal to the sum of the common voltage output and the determined kickback voltage. The method may include removing the activation signal from the pixel to store the data signal in the pixel to reduce the effect of kickback voltage on the pixel electrode of the pixel during shutdown of the electronic display.

摘要： 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.

摘要： Methods and devices for reducing a voltage difference between common voltage layers (VCOMs) of a display are provided. In one example, a method may include supplying an activation signal to a row of pixels of the display to activate the row of pixels. The method may also partially removing the activation signal from the row of pixels at a predetermined rate. The method may include detecting a voltage difference between a first VCOM of a first set of pixels of the display and a second VCOM of a second set of pixels of the display after the activation signal has been partially removed. The method may also include controlling removal of the activation signal from the row of pixels based at least partially on the detected voltage difference.
