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： 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.

摘要： Methods and devices are provided for controlling the brightness of a display for an electronic device based on ambient light conditions. In one embodiment, an electronic device may employ one or more brightness adjustment profiles for changing the brightness of a display based on the ambient light level. The brightness adjustment profiles may include two or more sections, each corresponding to different ambient light levels, which may be adjusted independently of one another. The different sections may allow a user to customize brightness adjustments for different ambient light conditions. In certain embodiments, the slope and/or offset of a section may be adjusted in response to receiving a user input that changes the brightness setting for a certain ambient light level.

摘要： Updating an image of a display is provided by scanning rows of sub-pixels of the display by applying voltages to pixel electrodes of adjacent sub-pixels in different lines such that polarity changes in opposite directions can occur in two sub-pixels that are adjacent to a particular sub-pixel. In one example, a positive-polarity voltage can be applied to one sub-pixel that is adjacent to a particular sub-pixel, causing a swing in the polarity of the sub-pixel from negative to positive. A negative-polarity voltage can be applied to another sub-pixel that is adjacent to the particular sub-pixel, swinging the polarity of the pixel electrode from positive to negative. A change in brightness of the particular sub-pixel that may result from a voltage swing one direction in an adjacent sub-pixel may be offset by a change in brightness of the particular sub-pixel that may result from a voltage swing in another adjacent sub-pixel.

摘要： Pre-charging display screen sub-pixels, such as aggressor sub-pixels, prior to the application of a target data voltage to the aggressor sub-pixels is provided. In some examples, a target voltage of a sub-pixel in a previous row in the scanning order of the display can be used to pre-charge sub-pixels. The row of sub-pixels to be pre-charged can be switched on during the updating of another row of sub-pixels. In this way, for example, target voltages applied to data lines while an update row is connected to the data lines, e.g., to update the update row, can be applied to the row to be pre-charged as well.
