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： Methods and devices useful in compensating for VDD and VTH variations in a micro light-emitting diode (micro-LED) display are provided. By way of example, an LED driver includes a first transistor having a first source coupled to an upper voltage rail (VDD), a first gate, and a first drain. The LED driver includes a second transistor having a second source coupled to the first drain of the first transistor, a second gate, and a second drain coupled to the LED. The second transistor is configured to receive the drive current signal from the first transistor and supply the drive current signal to the LED. The LED driver includes compensation circuitry configured to adjust the drive current signal such that the drive current signal is independent of the upper voltage rail (VDD) and a threshold voltage (VTH) of the first transistor or the second transistor.

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 data lines due to capacitive coupling between data lines. The resulting change in voltage on these adjacent data lines can give rise to visual artifacts in the data lines' corresponding sub-pixels. Various embodiments of the present disclosure serve to prevent or reduce these visual artifacts by applying voltage to a data line more than once during the write sequence. Doing so can allow erroneous brightening or darkening caused by large voltage swings to be overwritten without causing additional large voltage swings on the data line.

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 data lines due to capacitive coupling between data lines. The resulting change in voltage on these adjacent data lines can give rise to visual artifacts in the data lines' corresponding sub-pixels. Various embodiments of the present disclosure serve to prevent or reduce persisting visual artifacts by offsetting their effects or by distributing their presence among different colored sub-pixels. In some embodiments, this may be accomplished by using different write sequences during the update of a row of pixels.

摘要： Design criteria of display screens is provided that can be used in combination with particular inversion schemes and scanning orders of the display screens to reduce or eliminate visual artifacts that can be caused by the effects of capacitive coupling of voltage changes in one part of the display into other parts of the display. Using particular combinations of inversion schemes and scanning orders, together with particular design criteria for the display screen, can allow one type of effect, e.g., an increase or decrease in a brightness of a display pixel, caused by one type of coupling effect, such as a coupling between data lines, can be offset by the effect caused by another type of coupling effect, such as a coupling between pixel electrodes.

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： Shunt structures, such as shunt lines, that can be positioned between two adjacent pixel electrodes in different rows of display pixels in a display screen are provided. A conductive shunt structure between two pixel electrodes can be configured for reducing a capacitive coupling between the pixel electrodes. The shunt structure can be connected to a voltage source, such as ground, an AC ground, etc. In this way, for example, a pixel-to-pixel capacitance between adjacent pixel electrodes can be reduced.
