    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: Displaying an image on a display screen is provided by periodically changing the scanning order in which rows of sub-pixels of the display screen are scanned. One scanning order can be selected to scan the rows in the update of a first image frame of the display, and then a different scanning order can be selected to scan the rows in the update of a second image frame. Particular scanning orders can be selected in order to reduce or eliminate the appearance of visual artifacts by changing the location of the visual artifacts across multiple image frames. For example, different scanning orders that result in visual artifacts at different positions on the display screen can be used, and the selection of scanning order can periodically change among the different scanning orders such that the position of the visual artifacts changes periodically during the updating of multiple image frames.

    摘要: Devices and methods for reducing a variation in voltage perturbation between common voltage layers (VCOMs) of a display in response to voltage interference are provided. In one example, a resistive element may be coupled to one of several VCOMs to increase the resistance value of the VCOM. The resistive element may cause a variation in voltage perturbations between the several VCOMs to become generally more uniform, thereby reducing or eliminating certain image artifacts.

    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: Better performance can be provided for a display system that has semiconductor microelectronic components such as demultiplexors, gate line and data line drivers, and pixel switches formed on the display substrate, e.g., a glass substrate that constitutes part of an active matrix display panel. A gate source capacitance of a constituent transistor of one of these microelectronic components, e.g., a pixel thin film transistor (TFT) that is part of a particular display element, may be measured using a replica component that emulates the behavior of the component.

    摘要: Setting a slew rate, e.g., a rising time or a falling time, of a scanning signal can be performed with a first operation, and a shunting resistance of the scanning line can be set with a second operation. A scanning system that scans a display screen, a touch screen, etc., can set a desired slew rate during a first period of time and can set a desired shunting resistance during a second period of time. A gate line system can sequentially scan gate lines to display an image during a display phase of a touch screen. The gate line system can, for example, increase the falling times of gate line signals. After the falling gate line signal has stabilized, for example, the gate line system can decrease the shunting resistance of the gate line.
