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 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： A display is disclosed that includes a transparent substrate and a plurality of pixel transistors that are formed on the transparent substrate to generate an image for display. A transistor drive circuit is used to drive the pixel transistors to generate the image. The transistor drive circuit may include a gate driver. Further, a test circuit may be used to: adjust voltages that are applied by the gate driver to a pixel transistor; and determine the voltage of the gate driver when a current spike has occurred to the pixel transistor which causes the pixel transistor to turn on. Once this threshold voltage for the gate driver to turn on the pixel transistor has been determined, it may be stored in a storage device for future use by the gate driver. Other embodiments are also described and claimed.

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.
