Abstract: An electronic device may include an electronic display panel having multiple display pixels for displaying an image based on analog voltage signals. The electronic device may also include interpolation circuitry to generate the analog voltage signals based on digital image data corresponding to the image. The interpolation circuitry may also receive analog reference voltages and interpolate between sets of the analog reference voltages to generate intermediate voltages, which may be a part of the analog voltage signals. Interpolating between the sets analog reference voltages may include performing a first level interpolation of a first set of the analog reference voltages to generate a first intermediate voltage and performing a second level interpolation of a second set of the analog reference voltages to generate a second intermediate voltage, wherein the first level interpolation is different from the second level interpolation.

Abstract: An electronic display includes an active area including multiple pixels. The electronic display also includes a first row driver set including a first column of row drivers and a second column of row drivers. A first active row driver in the first column of row drivers drives a first portion of the multiple pixels, and a first spare row driver in the second column of row drivers is in an inactive state. The electronic display also includes a second row driver set including a third column of row drivers and a fourth column of row drivers. A third active row driver in the third column of row drivers drives a second portion of the multiple pixels, and a second spare row driver in the fourth column of row drivers is inactive.

Abstract: An electronic device may display image content via a tile-based display by controlling light emission from display pixels of the tile-based display. Based on image data associated with the image content, a processing circuitry of the tile-based display may receive a potential tile boundary. The processing circuitry may resample the image data based on geometry of the tile boundary and positions of the display pixels on the tile-based panel. After resampling the image data, the processing circuitry may adjust gain of the tile boundary display pixels according to a gain mask to compensate for the tile boundary.

Abstract: Aspects of the subject technology relate to displays for electronic devices and methods of operating the displays. The display may include an array of display pixels arranged in rows and columns. A v-drive operation in which rows are alternatingly operated about a center of each of two halves of the display is provided. Data rendering operations are provided that generate a virtual frame rate boost.

Abstract: An integrated touchscreen can include light emitting diodes or organic light emitting diodes (LEDs/OLEDs), display chiplets and touch chiplets disposed in a visible area of the integrated touch screen. For example, the LEDs/OLEDs, display chiplets and touch chiplets can be placed on a substrate by a micro-transfer tool. The integrated touchscreen can also include electrodes disposed in the visible area of the integrated touch screen. The electrodes can be capable of providing display functionality via the one or more display chiplets during display operation (e.g., operating as cathode terminals of the LEDs during the display operation) and capable of providing touch functionality via the touch chiplets during touch operation (e.g., touch node electrodes can be formed from groups of the electrodes and sensed). In some examples, the touch node electrodes can be formed and coupled to touch chiplets via the display chiplets.
