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.

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： 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： With respect to liquid crystal display inversion schemes, a large change in voltage on a data line can affect the voltages on adjacent floating data lines due to capacitive coupling between data lines. The change in voltage on these floating data lines can be increased when the application of voltage to the data line occurs after a toggling operation of the Vcom, i.e., when a voltage applied to the Vcom changes the voltage on the Vcom from one polarity to an opposite polarity. Various embodiments of the present disclosure serve to eliminate or reduce the effects of Vcom voltage toggling on data line voltages by applying a voltage (e.g., a fixed voltage) to the data lines while the voltage on Vcom toggles.
