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.

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： Systems and methods for testing a peripheral in accordance with a high-speed serial interface protocol are provided. A test system can test a peripheral by providing user-specified control over a test processor (which is substantially the same processor the peripheral will interface with when installed) to test, calibrate, or both test and calibrate the peripheral. The test processor can communicate with the peripheral according to the high-speed serial interface protocol, thereby effectively providing an actual “in-device” environment for testing and/or calibrating the peripheral.

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： Systems, devices, and methods for using clock detector circuitry to reduce turn-on time of an electronic display, improve image quality, and reduce operations of a host are provided. In one example, a system may include a host configured to transmit a number of signals and a display driver coupled to the host. The number of signals may include a clock signal and data signals. The display driver is configured to drive a display based at least in part on the data signals. The display driver is also configured to be reset upon detection of the clock signal without waiting for a host-issued reset signal. A clock detect circuit configured to detect the clock signal may be configured to transmit an internal reset signal to reset the display driver without a dedicated host-issued reset signal.
